LACTAM COMPOUNDS AND
THEIR USE AS PHARMACEUTICALS
FIELD OF THE INVENTION
The present invention relates to modulators of 11-P hydroxyl steroid dehydrogenase type 1
(11βHSDl) and/or mineralocorticoid receptor (MR), compositions thereof and methods of using the
same.
BACKGROUND OF THE INVENTION
Glucocorticoids are steroid hormones that regulate fat metabolism, function and distribution.
In vertebrates, glucocorticoids also have profound and diverse physiological effects on development,
neurobiology, inflammation, blood pressure, metabolism and programmed cell death. In humans, the
primary endogenously-produced glucocorticoid is cortisol. Cortisol is synthesized in the zona
fasciculate of the adrenal cortex under the control of a short-term neuroendocrine feedback circuit
called the hypothalamic-pituitary-adrenal (HPA) axis. Adrenal production of cortisol proceeds under
the control of adrenocorticotrophic hormone (ACTH), a factor produced and secreted by the anterior
pituitary. Production of ACTH in the anterior pituitary is itself highly regulated, driven by
corticotropin releasing hormone (CRH) produced by the paraventricular nucleus of the hypothalamus.
The HPA axis maintains circulating cortisol concentrations within restricted limits, with forward drive
at the diurnal maximum or during periods of stress, and is rapidly attenuated by a negative feedback
loop resulting from the ability of cortisol to suppress ACTH production in the anterior pituitary and
CRH production in the hypothalamus.
Aldosterone is another hormone produced by the adrenal cortex; aldosterone regulates sodium
and potassium homeostasis. Fifty years ago, a role for aldosterone excess in human disease was
reported in a description of the syndrome of primary aldosteronism (Conn, (1955), J. Lab. Clin. Med.
45: 6-17). It is now clear that elevated levels of aldosterone are associated with deleterious effects on
the heart and kidneys, and are a major contributing factor to morbidity and mortality in both heart
failure and hypertension.
Two members of the nuclear hormone receptor superfamily, glucocorticoid receptor (GR) and
mineralocorticoid receptor (MR), mediate cortisol function in vivo, while the primary intracellular
receptor for aldosterone is the MR. These receptors are also referred to as 'ligand-dependent
transcription factors,' because their functionality is dependent on the receptor being bound to its

WO 2006/053024 PCT/US2005/040550
ligand (for example, cortisol); upon ligand-binding these receptors directly modulate transcription via
DNA-binding zinc finger domains and transcriptional activation domains.
Historically, the major determinants of glucocorticoid action were attributed to three primary
factors: 1) circulating levels of glucocorticoid (driven primarily by the HPA axis), 2) protein binding
of glucocorticoids in circulation, and 3) intracellular receptor density inside target tissues. Recently, a
fourth determinant of glucocorticoid function was identified: tissue-specific pre-receptor metabolism
by glucocorticoid-activating and -inactivating enzymes. These 11-beta-hydroxysteroid dehydrogenase
(1 l-(3-HSD) enzymes act as pre-receptor control enzymes that modulate activation of the GR and MR
by regulation of glucocorticoid hormones. To date, two distinct isozymes of 11-beta-HSD have been
cloned and characterized: lipHSDl (also known as 11-beta-HSD type 1, llbetaHSDl, HSD11B1,
HDL, and HSD11L) and 11|3HSD2. lipHSDl and llpHSD2 catalyze the interconversion of
hormonally active cortisol (corticosterone in rodents) and inactive cortisone (11-
dehydrocorticosterone in rodents). lipHSDl is widely distributed in rat and human tissues;
expression of the enzyme and corresponding mRNA have been detected in lung, testis, and most
abundantly in liver and adipose tissue. lipHSDl catalyzes both 11-beta-dehydrogenation and the
reverse 11-oxoreduction reaction, although lipHSDl acts predominantly as a NADPH-dependent
oxoreductase in intact cells and tissues, catalyzing the activation of cortisol from inert cortisone (Low
et al. (1994) J. Mol. Endocrin. 13: 167-174) and has been reported to regulate glucocorticoid access to
the GR. Conversely, 11 (3HSD2 expression is found mainly in mineralocorticoid target tissues such as
kidney, placenta, colon and salivary gland, acts as an NAD-dependent dehydrogenase catalyzing the
inactivation of cortisol to cortisone (Albiston et al. (1994) Mol. Cell. Endocrin. 105: R11-R17), and
has been found to protect the MR from glucocorticoid excess, such as high levels of receptor-active
cortisol (Blum, et al., (2003) Prog. Nucl. Acid Res. Mol. Biol. 75:173-216).
In vitro, the MR binds cortisol and aldosterone with equal affinity. The tissue specificity of
aldosterone activity, however, is conferred by the expression of 11PHSD2 (Funder et al. (1988),
Science 242: 583-585). The inactivation of cortisol to cortisone by 11PHSD2 at the site of the MR
enables aldosterone to bind to this receptor in vivo. The binding of aldosterone to the MR results in
dissociation of the ligand-activated MR from a multiprotein complex containing chaperone proteins,
translocation of the MR into the nucleus, and its binding to hormone response elements in regulatory
regions of target gene promoters. Within the distal nephron of the kidney, induction of serum and
glucocorticoid inducible kinase-1 (sgk-1) expression leads to the absorption of Na+ ions and water
through the epithelial sodium channel, as well as potassium excretion with subsequent volume
expansion and hypertension (Bhargava et al., (2001), Endo 142: 1587-1594).
In humans, elevated aldosterone concentrations are associated with endothelial dysfunction,
myocardial infarction, left ventricular atrophy, and death. In attempts to modulate these ill effects,
multiple intervention strategies have been adopted to control aldosterone overactivity and attenuate
2

WO 2006/053024 PCT/US2005/040550
the resultant hypertension and its associated cardiovascular consequences. Inhibition of angiotensin-
converting enzyme (ACE) and blockade of the angiotensin type 1 receptor (AT1R) are two strategies
that directly impact the rennin-angiotensin-aldosterone system (RAAS). However, although ACE
inhibition and AT1R antagonism initially reduce aldosterone concentrations, circulating
concentrations of this hormone return to baseline levels with chronic therapy (known as 'aldosterone
escape'). Importantly, co-administration of the MR antagonist Spironolactone or Eplerenone directly
blocks the deleterious effects of this escape mechanism and dramatically reduces patient mortality
(Pitt et al., New England J. Med. (1999), 341: 709-719; Pitt et al., New England J. Med. (2003), 348:
1309-1321). Therefore, MR antagonism may be an important treatment strategy for many patients
with hypertension and cardiovascular disease, particularly those hypertensive patients at risk for
target-organ damage.
Mutations in either of the genes encoding the 11-beta-HSD enzymes are associated with
human pathology. For example, lipHSD2 is expressed in aldosterone-sensitive tissues such as the
distal nephron, salivary gland, and colonic mucosa where its cortisol dehydrogenase activity serves to
protect the intrinsically non-selective MR from illicit occupation by cortisol (Edwards et al. (1988)
Lancet 2: 986-989). Individuals with mutations in 11PHSD2 are deficient in this cortisol-inactivation
activity and, as a result, present with a syndrome of apparent mineralocorticoid excess (also referred
to as 'SAME') characterized by hypertension, hypokalemia, and sodium retention (Wilson et al.
(1998) Proc. Natl. Acad. Sci. 95: 10200-10205). Likewise, mutations in liptlSDl, a primary
regulator of tissue-specific glucocorticoid bioavailability, and in the gene encoding a co-localized
NADPH-generating enzyme, hexose 6-phosphate dehydrogenase (H6PD), can result in cortisone
reductase deficiency (CRD), in which activation of cortisone to cortisol does not occur, resulting in
adrenocorticotropin-mediated androgen excess. CRD patients excrete virtually all glucocorticoids as
cortisone metabolites (tetrahydrocortisone) with low or absent cortisol metabolites
(tetrahydrocortisols). When challenged with oral cortisone, CRD patients exhibit abnormally low
plasma cortisol concentrations. These individuals present with ACTH-mediated androgen excess
(hirsutism, menstrual irregularity, hyperandrogenism), a phenotype resembling polycystic ovary
syndrome (PCOS) (Draper et al. (2003) Nat. Genet. 34: 434-439).
The importance of the HPA axis in controlling glucocorticoid excursions is evident from the
fact that disruption of homeostasis in the HPA axis by either excess or deficient secretion or action
results in dishing's syndrome or Addison's disease, respectively (Miller and Chrousos (2001)
Endocrinology and Metabolism, eds. Felig and Frohman (McGraw-Hill, New York), 4th Ed.: 387-
524). Patients with Cushing's syndrome (a rare disease characterized by systemic glucocorticoid
excess originating from the adrenal or pituitary tumors) or receiving glucocorticoid therapy develop
reversible visceral fat obesity. Interestingly, the phenotype of Cushing's syndrome patients closely
resembles that of Reaven's metabolic syndrome (also known as Syndrome X or insulin resistance
3

WO 2006/053024 PCT/US2005/040550
syndrome) the symptoms of which include visceral obesity, glucose intolerance, insulin resistance,
hypertension, type 2 diabetes and hyperlipidemia (Reaven (1993) Ann. Rev. Med. 44: 121-131).
However, the role of glucocorticoids in prevalent forms of human obesity has remained obscure
because circulating glucocorticoid concentrations are not elevated in the majority of metabolic
syndrome patients. In fact, glucocorticoid action on target tissue depends not only on circulating
levels but also on intracellular concentration, locally enhanced action of glucocorticoids in adipose
tissue and skeletal muscle has been demonstrated in metabolic syndrome. Evidence has accumulated
that enzyme activity of 11βHSDl, which regenerates active glucocorticoids from inactive forms and
plays a central role in regulating intracellular glucocorticoid concentration, is commonly elevated in
fat depots from obese individuals. This suggests a role for local glucocorticoid reactivation in obesity
and metabolic syndrome.
Given the ability of 11βHSDl to regenerate cortisol from inert circulating cortisone,
considerable attention has been given to its role in the amplification of glucocorticoid function.
11βHSDl is expressed in many key GR-rich tissues, including tissues of considerable metabolic
importance such as liver, adipose, and skeletal muscle, and, as such, has been postulated to aid in the
tissue-specific potentiation of glucocorticoid-mediated antagonism of insulin function. Considering a)
the phenotypic similarity between glucocorticoid excess (Cushing's syndrome) and the metabolic
syndrome with normal circulating glucocorticoids in the latter, as well as b) the ability of 1 lpHSDl to
generate active cortisol from inactive cortisone in a tissue-specific manner, it has been suggested that
central obesity and the associated metabolic complications in syndrome X result from increased
activity of 1 lpHSDl within adipose tissue, resulting in 'Cushing's disease of the omentum' (Bujalska
et al. (1997) Lancet 349: 1210-1213). Indeed, 1 lpHSDl has been shown to be upregulated in adipose
tissue of obese rodents and humans (Livingstone et al. (2000) Endocrinology 131: 560-563; Rask et
al. (2001) J. Clin. Endocrinol. Metab. 86: 1418-1421; Lindsay et al. (2003) J. Clin. Endocrinol.
Metab. 88: 2738-2744; Wake et al. (2003) J. Clin. Endocrinol. Metab. 88: 3983-3988).
Additional support for this notion has come from studies in mouse transgenic models.
Adipose-specific overexpression of lipHSDl under the control of the aP2 promoter in mouse
produces a phenotype remarkably reminiscent of human metabolic syndrome (Masuzaki et al. (2001)
Science 294: 2166-2170; Masuzaki et al. (2003) J. Clinical Invest. 112: 83-90). Importantly, this
phenotype occurs without an increase in total circulating corticosterone, but rather is driven by a local
production of corticosterone within the adipose depots. The increased activity of lipHSDl in these
mice (2-3 fold) is very similar to that observed in human obesity (Rask et al. (2001) J. Clin.
Endocrinol. Metab. 86: 1418-1421). This suggests that local lipHSDl-mediated conversion of inert
glucocorticoid to active glucocorticoid can have profound influences whole body insulin sensitivity.
Based on this data, it would be predicted that the loss of lipHSDl would lead to an increase
in insulin sensitivity and glucose tolerance due to a tissue-specific deficiency in active glucocorticoid
4

WO 2006/053024 PCT/US2005/040550
levels. This is, in fact, the case as shown in studies with 11βHSDl-deficient mice produced by
homologous recombination (Kotelevstev et al. (1997) Proc. Natl. Acad. Sci. 94: 14924-14929; Morton
et al. (2001) J. Biol. Chem. 276: 41293-41300; Morton et al. (2004) Diabetes 53: 931-938). These
mice are completely devoid of 11-keto reductase activity, confirming that 1 lpHSDl encodes the only
activity capable of generating active corticosterone from inert 11-dehydrocorticosterone. lipHSDl-
deficient mice are resistant to diet- and stress-induced hyperglycemia, exhibit attenuated induction of
hepatic gluconeogenic enzymes (PEPCK, G6P), show increased insulin sensitivity within adipose,
and have an improved lipid profile (decreased triglycerides and increased cardio-protective HDL).
Additionally, these animals show resistance to high fat diet-induced obesity. Taken together, these
transgenic mouse studies confirm a role for local reactivation of glucocorticoids in controlling hepatic
and peripheral insulin sensitivity, and suggest that inhibition of lipHSDl activity may prove
beneficial in treating a number of glucocorticoid-related disorders, including obesity, insulin
resistance, hyperglycemia, and hyperlipidemia.
Data in support of this hypothesis has been published. Recently, it was reported that
11βHSDl plays a role in the pathogenesis of central obesity and the appearance of the metabolic
syndrome in humans. Increased expression of the 1 lpHSDl gene is associated with metabolic
abnormalities in obese women and that increased expression of this gene is suspected to contribute to
the increased local conversion of cortisone to cortisol in adipose tissue of obese individuals (Engeli, et
al., (2004) Obes. Res. 12: 9-17).
A new class of lipHSDl inhibitors, the arylsulfonamidothiazoles, was shown to improve
hepatic insulin sensitivity and reduce blood glucose levels in hyperglycemic strains of mice (Barf et
al. (2002) J. Med. Chem. 45: 3813-3815; Alberts et al. Endocrinology (2003) 144: 4755-4762).
Furthermore, it was recently reported that selective inhibitors of lipHSDl can ameliorate severe
hyperglycemia in genetically diabetic obese mice. Thus, lipHSDl is a promising pharmaceutical
target for the treatment of the Metabolic Syndrome (Masuzaki, et al., (2003) Curr. Drug Targets
Immune Endocr. Metabol. Disord. 3: 255-62).
A. Obesity and metabolic syndrome
As described above, multiple lines of evidence suggest that inhibition of 1 lpHSDl activity
can be effective in combating obesity and/or aspects of the metabolic syndrome cluster, including
glucose intolerance, insulin resistance, hyperglycemia, hypertension, and/or hyperlipidemia.
Glucocorticoids are known antagonists of insulin action, and reductions in local glucocorticoid levels
by inhibition of intracellular cortisone to cortisol conversion should increase hepatic and/or peripheral
insulin sensitivity and potentially reduce visceral adiposity. As described above, lipHSDl knockout
mice are resistant to hyperglycemia, exhibit attenuated induction of key hepatic gluconeogenic
enzymes, show markedly increased insulin sensitivity within adipose, and have an improved lipid
5

WO 2006/053024 PCT/US2005/040550
profile. Additionally, these animals show resistance to high fat diet-induced obesity (Kotelevstev et
al. (1997) Proc. Natl. Acad. Sci. 94: 14924-14929; Morton et al. (2001) J. Biol. Chem. 276: 41293-
41300; Morton et al. (2004) Diabetes 53: 931-938). Thus, inhibition of llpHSDl is predicted to have
multiple beneficial effects in the liver, adipose, and/or skeletal muscle, particularly related to
alleviation of component(s) of the metabolic syndrome and/or obesity.
B. Pancreatic function
Glucocorticoids are known to inhibit the glucose-stimulated secretion of insulin from
pancreatic beta-cells (Billaudel and Sutter (1979) Horm. Metab. Res. 11: 555-560). In both Cushing's
syndrome and diabetic Zucker fa/fa rats, glucose-stimulated insulin secretion is markedly reduced
(Ogawa et al. (1992) J. Clin. Invest. 90: 497-504). I lpHSDl mRNA and activity has been reported in
the pancreatic islet cells of ob/ob mice and inhibition of this activity with carbenoxolone, an
11βpHSDl inhibitor, improves glucose-stimulated insulin release (Davani et al. (2000) J. Biol. Chem.
275: 34841-34844). Thus, inhibition of 11|3HSD1 is predicted to have beneficial effects on the
pancreas, including the enhancement of glucose-stimulated insulin release.
C. Cognition and dementia
Mild cognitive impairment is a common feature of aging that may be ultimately related to the
progression of dementia. In both aged animals and humans, inter-individual differences in general
cognitive function have been linked to variability in the long-term exposure to glucocorticoids
(Lupien et al. (1998) Nat. Neurosci. 1: 69-73). Further, dysregulation of the HPA axis resulting in
chronic exposure to glucocorticoid excess in certain brain subregions has been proposed to contribute
to the decline of cognitive function (McEwen and Sapolsky (1995) Curr. Opin. Neurobiol. 5: 205-
216). llpHSDl is abundant in the brain, and is expressed in multiple subregions including the
hippocampus, frontal cortex, and cerebellum (Sandeep et al. (2004) Proc. Natl. Acad. Sci. Early
Edition: 1-6). Treatment of primary hippocampal cells with the llpHSDl inhibitor carbenoxolone
protects the cells from glucocorticoid-mediated exacerbation of excitatory amino acid neurotoxicity
(Rajan et al. (1996) J. Neurosci. 16: 65-70). Additionally, llpHSDl-deficient mice are protected
from glucocorticoid-associated hippocampal dysfunction that is associated with aging (Yau et al.
(2001) Proc. Natl. Acad. Sci. 98: 4716-4721). In two randomized, double-blind, placebo-controlled
crossover studies, administration of carbenoxolone improved verbal fluency and verbal memory
(Sandeep et al. (2004) Proc. Natl. Acad. Sci. Early Edition: 1-6). Thus, inhibition of lipHSDl is
predicted to reduce exposure to glucocorticoids in the brain and protect against deleterious
glucocorticoid effects on neuronal function, including cognitive impairment, dementia, and/or
depression.

D. Intra-ocular pressure
Glucocorticoids can be used topically and systemically for a wide range of conditions in
clinical ophthalmology. One particular complication with these treatment regimens is corticosteroid-
induced glaucoma. This pathology is characterized by a significant increase in intra-ocular pressure
(IOP). In its most advanced and untreated form, IOP can lead to partial visual field loss and
eventually blindness. IOP is produced by the relationship between aqueous humour production and
drainage. Aqueous humour production occurs in the non-pigmented epithelial cells (NPE) and its
drainage is through the cells of the trabecular meshwork. 1 ipi-ISDl has been localized to NPE cells
(Stokes et al. (2000) Invest. Ophthalmol. Vis. Sci. 41: 1629-1683; Rauz et al. (2001) Invest.
Ophthalmol. Vis. Sci. 42: 2037-2042) and its function is likely relevant to the amplification of
glucocorticoid activity within these cells. This notion has been confirmed by the observation that free
cortisol concentration greatly exceeds that of cortisone in the aqueous humour (14:1 ratio). The
functional significance of lipi-ISDl in the eye has been evaluated using the inhibitor carbenoxolone
in healthy volunteers (Rauz et al. (2001) Invest. Ophthalmol. Vis. Sci. 42: 2037-2042). After seven
days of carbenoxolone treatment, IOP was reduced by 18%. Thus, inhibition of lipHSDl in the eye
is predicted to reduce local glucocorticoid concentrations and IOP, producing beneficial effects in the
management of glaucoma and other visual disorders.
E. Hypertension
Adipocyte-derived hypertensive substances such as leptin and angiotensinogen have been
proposed to be involved in the pathogenesis of obesity-related hypertension (Matsuzawa et al. (1999)
Ann. N.Y. Acad. Sci. 892: 146-154; Wajchenberg (2000) Endocr. Rev. 21: 697-738). Leptin, which
is secreted in excess in aP2-lipHSDl transgenic mice (Masuzaki et al. (2003) J. Clinical Invest. 112:
83-90), can activate various sympathetic nervous system pathways, including those that regulate
blood pressure (Matsuzawa et al. (1999) Ann. N.Y. Acad. Sci. 892: 146-154). Additionally, the renin-
angiotensin system (RAS) has been shown to be a major determinant of blood pressure (Walker et al.
(1979) Hypertension 1: 287-291). Angiotensinogen, which is produced in liver and adipose tissue, is
the key substrate for renin and drives RAS activation. Plasma angiotensinogen levels are markedly
elevated in aP2-lipHSDl transgenic mice, as are angiotensin II and aldosterone (Masuzaki et al.
(2003) J. Clinical Invest. 112: 83-90). These forces likely drive the elevated blood pressure observed
in aP2-lipHSDl transgenic mice. Treatment of these mice with low doses of an angiotensin II
receptor antagonist abolishes this hypertension (Masuzaki et al. (2003) J. Clinical Invest. 112: 83-90).
This data illustrates the importance of local glucocorticoid reactivation in adipose tissue and liver, and
suggests that hypertension may be caused or exacerbated by lipHSDl activity. Thus, inhibition of
1 lpHSDl and reduction in adipose and/or hepatic glucocorticoid levels is predicted to have beneficial
effects on hypertension and hypertension-related cardiovascular disorders.
7

WO 2006/053024 PCT/US2005/040550
F. Bone disease
Glucocorticoids can have adverse effects on skeletal tissues. Continued exposure to even
moderate glucocorticoid doses can result in osteoporosis (Cannalis (1996) J. Clin. Endocrinol. Metab.
81: 3441-3447) and increased risk for fractures. Experiments in vitro confirm the deleterious effects
of glucocorticoids on both bone-resorbing cells (also known as osteoclasts) and bone forming cells
(osteoblasts). lipHSDl has been shown to be present in cultures of human primary osteoblasts as
well as cells from adult bone, likely a mixture of osteoclasts and osteoblasts (Cooper et al. (2000)
Bone 27: 375-381), and the lipHSDl inhibitor carbenoxolone has been shown to attenuate the
negative effects of glucocorticoids on bone nodule formation (Bellows et al. (1998) Bone 23: 119-
125). Thus, inhibition of 11|3HSD1 is predicted to decrease the local glucocorticoid concentration
within osteoblasts and osteoclasts, producing beneficial effects in various forms of bone disease,
including osteoporosis.
Small molecule inhibitors of 11βHSDl are currently being developed to treat or prevent
11βHSDl-related diseases such as those described above. For example, certain amide-based
inhibitors are reported in WO 2004/089470, WO 2004/089896, WO 2004/056745, and WO
2004/065351.
Antagonists of 11βHSDl1 have been evaluated in human clinical trials (Kurukulasuriya, et al.,
(2003) Curr. Med. Chem. 10: 123-53).
In light of the experimental data indicating a role for lipHSDl in glucocorticoid-related
disorders, metabolic syndrome, hypertension, obesity, insulin resistance, hyperglycemia,
hyperlipidemia, type 2 diabetes, androgen excess (hirsutism, menstrual irregularity,
hyperandrogenism) and polycystic ovary syndrome (PCOS), therapeutic agents aimed at
augmentation or suppression of these metabolic pathways, by modulating glucocorticoid signal
transduction at the level of 1 lpHSDl are desirable.
Furthermore, because the MR binds to aldosterone (its natural ligand) and cortisol with equal
affinities, compounds that are designed to interact with the active site of lipi-ISDl (which binds to
cortisone/cortisol) may also interact with the MR and act as antagonists. Because the MR is
implicated in heart failure, hypertension, and related pathologies including atherosclerosis,
arteriosclerosis, coronary artery disease, thrombosis, angina, peripheral vascular disease, vascular wall
damage, and stroke, MR antagonists are desirable and may also be useful in treating complex
cardiovascular, renal, and inflammatory pathologies including disorders of lipid metabolism including
dyslipidemia or hyperlipoproteinaemia, diabetic dyslipidemia, mixed dyslipidemia,
hypercholesterolemia, hypertriglyceridemia, as well as those associated with type 1 diabetes, type 2
diabetes, obesity, metabolic syndrome, and insulin resistance, and general aldosterone-related target-
organ damage.

The compounds described herein can be asymmetric (e.g., having one or more stereocenters).
All stereoisomers, such as enantiomers and diastereomers, are intended unless otherwise indicated.
Compounds of the present invention that contain asymmetrically substituted carbon atoms can be
isolated in optically active or racemic forms. Methods on how to prepare optically active forms from
optically active starting materials are known in the art, such as by resolution of racemic mixtures or
by stereoselective synthesis. Many geometric isomers of olefins, C=N double bonds, and the like can
also be present in the compounds described herein, and all such stable isomers are contemplated in the
present invention. Cis and trans geometric isomers of the compounds of the present invention are
described and may be isolated as a mixture of isomers or as separated isomeric forms.
Resolution of racemic mixtures of compounds can be carried out by any of numerous methods
known in the art. An example method includes fractional recrystallizaion using a chiral resolving acid
which is an optically active, salt-forming organic acid. Suitable resolving agents for fractional
recrystallization methods are, for example, optically active acids, such as the D and L forms of tartaric
acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid or the various
optically active camphprsulfonic acids such as p-camphorsulfonic acid. Other resolving agents
suitable for fractional crystallization methods include stereoisomerically pure forms of a-
methylbenzylamine (e.g., S and R forms, or diastereomerically pure forms), 2-phenylglycinol,
norephedrine, ephedrine, N-methylephedrine, cyclohexylethylamine, 1,2-diaminocyclohexane, and
the like.
Resolution of racemic mixtures can also be carried out by elution on a column packed with an
optically active resolving agent (e.g., dinitrobenzoylphenylglycine). Suitable elution solvent
composition can be determined by one skilled in the art.
Compounds of the invention also include tautomeric forms, such as keto-enol tautomers.
Compounds of the invention further include hydrates and solvates, as well as anyhydrous and
non-solvated forms.

Compounds of the invention can also include all isotopes of atoms occurring in the
intermediates or final compounds. Isotopes include those atoms having the same atomic number but
different mass numbers. For example, isotopes of hydrogen include tritium and deuterium.
The phrase "pharmaceutically acceptable" is employed herein to refer to those compounds,
materials, compositions, and/or dosage forms which are, within the scope of sound medical
judgement, suitable for use in contact with the tissues of human beings and animals without excessive
toxicity, irritation, allergic response, or other problem or complication, commensurate with a
reasonable benefit/risk ratio.
The present invention also includes pharmaceutically acceptable salts of the compounds
described herein. As used herein, "pharmaceutically acceptable salts" refers to derivatives of the
disclosed compounds wherein the parent compound is modified by converting an existing acid or base
moiety to its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to,
mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues
such as carboxylic acids; and the like. The pharmaceutically acceptable salts of the present invention
include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound
formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable
salts of the present invention can be synthesized from the parent compound which contains a basic or
acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting
the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base
or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like
ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found
in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p.
1418 and Journal of Pharmaceutical Science, 66, 2 (1977), each of which is incorporated herein by
reference in its entirety.
The present invention also includes prodrugs of the compounds described herein. As used
herein, "prodrugs" refer to any covalently bonded carriers which release the active parent drug when
administered to a mammalian subject. Prodrugs can be prepared by modifying functional groups
present in the compounds in such a way that the modifications are cleaved, either in routine
manipulation or in vivo, to the parent compounds. Prodrugs include compounds wherein hydroxyl,
amino, sulfhydryl, or carboxyl groups are bonded to any group that, when administered to a
mammalian subject, cleaves to form a free hydroxyl, amino, sulfhydryl, or carboxyl group
respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate

Synthesis
The novel compounds of the present invention can be prepared in a variety of ways known to
one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized
using the methods as hereinafter described below, together with synthetic methods known in the art of
synthetic organic chemistry or variations thereon as appreciated by those skilled in the art.
The compounds of this invention can be prepared from readily available starting materials
using the following general methods and procedures. It will be appreciated that where typical or
preferred process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents,
pressures, etc.) are given; other process conditions can also be used unless otherwise stated. Optimum
reaction conditions may vary with the particular reactants or solvent used, but such conditions can be
determined by one skilled in the art by routine optimization procedures.
The processes described herein can be monitored according to any suitable method known in
the art. For example, product formation can be monitored by spectroscopic means, such as nuclear
magnetic resonance spectroscopy (e.g., 'H or 13C) infrared spectroscopy, spectrophotometry (e.g.,
UV-visible), or mass spectrometry, or by chromatography such as high performance liquid
chromatograpy (HPLC) or thin layer chromatography.
Preparation of compounds can involve the protection and deprotection of various chemical
groups. The need for protection and deprotection, and the selection of appropriate protecting groups
can be readily determined by one skilled in the art. The chemistry of protecting groups can be found,
for example, in Greene, et al., Protective Groups in Organic Synthesis, 2d. Ed., Wiley & Sons, 1991,
which is incorporated herein b)' reference in its entirety.
The reactions of the processes described herein can be carried out in suitable solvents which
can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be
substantially nonreactive with the starting materials (reactants), the intermediates, or products at the
temperatures at which the reactions are carried out, i.e., temperatures which can range from the
solvent's freezing temperature to the solvent's boiling temperature. A given reaction can be carried
out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step,
suitable solvents for a particular reaction step can be selected.
The compounds of the invention can be prepared, for example, using the reaction pathways
and techniques described below.
Compounds of the invention can be generally prepared by the method outlined in Scheme 1.
Reagents of formula 1-1 (X is a leaving group such as halo) can be reacted with an amines of formula
1-2 (or its salts) in an appropriate solvent (e.g., CH2C12) and optionally in the presence of a base such
as diisopropyl ethyl amine to provide the desired products 1-3. As an example, sulfonyl chlorides of
formula 1-4 can be reacted with the amines of formula 1-2 to provide sulfonyl linked compounds of
formula 1-5.

A series of spirocyclyl amines of formula 2-8 can be prepared according to the procedure
outlined in Scheme 2. N-protected 2-1 (Pr is an amino protecting group such as Boc) can be treated
with a base such as LDA at low temperature in a solvent such as tetrahydrofuran followed by addition
of l-bromo-3-methyl-2-butene (2-2). The resulting intermediate (2-3) can be treated with ozone and
then reduced with methyl sulfide to provide the aldehyde 2-4. Reductive amination of 2-4 with
amines 2-5 can be conducted in a solvent such as methanol and using a reducing agent such as sodium
triacetoxyborohydride, and the product 2-6 can be cyclized in the presence of a base such as
isopropylmagnesium bromide to provide the lactam 2-7 which upon acidic cleavage of the Boc group
yields the desired amine 2-8.
29

WO 2006/053024 PCT/US2005/040550

A series of amines of formula 3-7 can be prepared according to the procedure outlined in
Scheme 3. Treatment of Boc protected nipecotic ethyl ester 3-1 with a base such as LDA at low
temperature in a solvent such as tetrahydrofuran followed by addition of l-bromo-3-methyl-2-
butene can result in an intermediate 3-2, which can be treated with ozone followed by reduction
with methyl sulfide to provide the aldehyde 3-3. Reductive animation of 3-3 with amines 3-4
(where Qi is, e.g., substituted or unsubstituted cycloalkyl or aryl) can be conducted in a solvent
such as methanol and using a reducing agent such as sodium triacetoxyborohydride. The
resulting intermediate 3-5 can be cyclized in the presence of a base such as isopropylmagnesium
bromide to provide the lactam 3-6 which upon acidic cleavage of the Boc group yields the desired
piperidine 3-7.

WO 2006/053024 PCT/US2005/040550
Alternatively, treatment of compound 5-1 with alkyl amines R3cNH2 and sodium cyanide can
provide alkylated hydantoin derivatives 5-2. Aromatic substituted hydantoins 5-4 can be obtained by
coupling compounds 5-2 with aromatic boronic acids or aromatic halides 5-3 in the presence of
catalyst. Acidic cleavage of the Boc group yields the desired piperidines 5-4 (Scheme 5).

In a further alternative route, piperdines 6-6 can also be prepared by the method outlined in
Scheme 6. The protected amino acid 6-1 can be coupled with an amine Q-NH2 using a coupling
agent such as BOP to provide compound 6-2 which, in turn, can be hydrogenated at the presence
of Pd catalyst to yield compound 6-3. Compound 6-3 can be treated with methyl chloroformate
and a base such as triethyl amine in CH2CI2 to complete the ring closure and form hydantoin 6-4.
As described previously, N alkylation with R3cX (X is a leaving group such as halo) can yield
compounds of formula 6-5 and acid cleavage can yield compounds of formula 6-6.

Pharmaceutical Formulations and Dosage Forms
When employed as pharmaceuticals, the compounds of Formula I can be administered in the
form of pharmaceutical compositions. These compositions can be prepared in a manner well known in
the pharmaceutical art, and can be administered by a variety of routes, depending upon whether local
or systemic treatment is desired and upon the area to be treated. Administration may be topical
(including ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery),
pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer;
intratracheal, intranasal, epidermal and transdermal), ocular, oral or parenteral. Methods for ocular
delivery can include topical administration (eye drops), subconjunctival, periocular or intravitreal
injection or introduction by balloon catheter or ophthalmic inserts surgically placed in the
conjunctival sac. Parenteral administration includes intravenous, intraarterial, subcutaneous,
intraperitoneal or intramuscular injection or infusion; or intracranial, e.g., intrathecal or
35

WO 2006/053024 PCT/US2005/040550
intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or
may be, for example, by a continuous perfusion pump. Pharmaceutical compositions and formulations
for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops,
suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or
oily bases, thickeners and the like may be necessary or desirable.
This invention also includes pharmaceutical compositions which contain, as the active
ingredient, one or more of the compounds of the invention above in combination with one or more
pharmaceutically acceptable carriers. In malting the compositions of the invention, the active
ingredient is typically mixed with an excipient, diluted by an excipient or enclosed within such a
carrier in the form of, for example, a capsule, sachet, paper, or other container. When the excipient
serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or
medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders,
lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in
a liquid medium), ointments containing, for example, up to 10 % by weight of the active compound,
soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged
powders.
In preparing a formulation, the active compound can be milled to provide the appropriate
particle size prior to combining with the other ingredients. If the active compound is substantially
insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is
substantially water soluble, the particle size can be adjusted by milling to provide a substantially
uniform distribution in the formulation, e.g. about 40 mesh.
Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol,
starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate,
microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. The
formulations can additionally include: lubricating agents such as talc, magnesium stearate, and
mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and
propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the invention
can be formulated so as to provide quick, sustained or delayed release of the active ingredient after
administration to the patient by employing procedures known in the art.
The compositions can be formulated in a unit dosage form, each dosage containing from
about 5 to about 100 mg, more usually about 10 to about 30 mg, of the active ingredient. The term
"unit dosage forms" refers to physically discrete units suitable as unitary dosages for human subjects
and other mammals, each unit containing a predetermined quantity of active material calculated to
produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.
The active compound can be effective over a wide dosage range and is generally administered
in a pharmaceutically effective amount. It will be understood, however, that the amount of the
compound actually administered will usually be determined by a physician, according to the relevant
36

WO 2006/053024 PCT/US2005/040550
circumstances, including the condition to be treated, the chosen route of administration, the actual
compound administered, the age, weight, and response of the individual patient, the severity of the
patient's symptoms, and the like.
For preparing solid compositions such as tablets, the principal active ingredient is mixed with
a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous
mixture of a compound of the present invention. When referring to these preformulation compositions
as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so
that the composition can be readily subdivided into equally effective unit dosage forms such as
tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the
type described above containing from, for example, 0.1 to about 500 mg of the active ingredient of the
present invention.
The tablets or pills of the present invention can be coated or otherwise compounded to
provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can
comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope
over the former. The two components can be separated by an enteric layer which serves to resist
disintegration in the stomach and permit the inner component to pass intact into the duodenum or to
be delayed in release. A variety of materials can be used for such enteric layers or coatings, such
materials including a number of polymeric acids and mixtures of polymeric acids with such materials
as shellac, cetyl alcohol, and cellulose acetate.
The liquid forms in which the compounds and compositions of the present invention can be
incorporated for administration orally or by injection include aqueous solutions, suitably flavored
syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil,
sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.
Compositions for inhalation or insufflation include solutions and suspensions in
pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The
liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described
supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route
for local or systemic effect. Compositions in can be nebulized by use of inert gases. Nebulized
solutions may be breathed directly from the nebulizing device or the nebulizing device can be
attached to a face masks tent, or intermittent positive pressure breathing machine. Solution,
suspension, or powder compositions can be administered orally or nasally from devices which deliver
the formulation in an appropriate manner.
The amount of compound or composition administered to a patient will vary depending upon
what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state
of the patient, the manner of administration, and the like. In therapeutic applications, compositions
can be administered to a patient already suffering from a disease in an amount sufficient to cure or at
least partially arrest the symptoms of the disease and its complications. Effective doses will depend on
37

WO 2006/053024 PCT/US2005/040550
the disease condition being treated as well as by the judgment of the attending clinician depending
upon factors such as the severity of the disease, the age, weight and general condition of the patient,
and the like.
The compositions administered to a patient can be in the form of pharmaceutical
compositions described above. These compositions can be sterilized by conventional sterilization
techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized,
the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The
pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and
most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients,
carriers, or stabilizers will result in the formation of pharmaceutical salts.
The therapeutic dosage of the compounds of the present invention can vary according to, for
example, the particular use for which the treatment is made, the manner of administration of the
compound, the health and condition of the patient, and the judgment of the prescribing physician. The
proportion or concentration of a compound of the invention in a pharmaceutical composition can vary
depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobichy),
and the route of administration. For example, the compounds of the invention can be provided in an
aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for
parenteral adminstration. Some typical dose ranges are from about 1 |^g/kg to about 1 g/kg of body
weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg
of body weight per day. The dosage is likely to depend on such variables as the type and extent of
progression of the disease or disorder, the overall health status of the particular patient, the relative
biological efficacy of the compound selected, formulation of the excipient, and its route of
administration. Effective doses can be extrapolated from dose-response curves derived from in vitro
or animal model test systems.
The compounds of the invention can also be formulated in combination with one or more
additional active ingredients which can include any pharmaceutical agent such as anti-viral agents,
antibodies, immune suppressants, anti-inflammatory agents and the like.
Labeled Compounds and Assay Methods
Another aspect of the present invention relates to labeled compounds of the invention (radio-
labeled, fluorescent-labeled, etc.) that would be useful not only in radio-imaging but also in assays,
both in vitro and in vivo, for localizing and quantitating the enzyme in tissue samples, including
human, and for identifying ligands by inhibition binding of a labeled compound. Accordingly, the
present invention includes enzyme assays that contain such labeled compounds.
The present invention further includes isotopically-labeled compounds of the invention. An
"isotopically" or "radio-labeled" compound is a compound of the invention where one or more atoms
are replaced or substituted by an atom having an atomic mass or mass number different from the
38

WO 2006/053024 PCT/US2005/040550
atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable
radionuclides that may be incorporated in compounds of the present invention include but are not
limited to 2H (also written as D for deuterium), 3H (also written as T for tritium), nC, 13C, 14C, 13N,
I5N, 15O, 17O, I8O, 18F, 35S, 36C1,82Br, 75Br, 76Br, 77Br, 123I, 124I, 125I and 131I. The radionuclide that is
incorporated in the instant radio-labeled compounds will depend on the specific application of that
radio-labeled compound. For example, for in vifro receptor labeling and competition assays,
compounds that incorporate 3H, 14C, 82Br, 1251, 1311,3:iS or will generally be most useful. For radio-
imaging applications nC, 18F, 125I, 123I, 1241,1311,75Br, 76Br or 77Br will generally be most useful.
It is understood that a "radio-labeled compound" is a compound that has incorporated at least
one radionuclide. In some embodiments the radionuclide is selected from the group consisting of 3H,
14C,125I,35Sand82Br.
In some embodiments, the labeled compounds of the present invention contain a fluorescent
lable.
Synthetic methods for incorporating radio-isotopes and fluorescent labels into organic
compounds are are well known in the art.
A labeled compound of the invention (radio-labeled, fluorescent-labeled, etc.) can be used in
a screening assay to identify/evaluate compounds. For example, a newly synthesized or identified
compound (i.e., test compound) which is labeled can be evaluated for its ability to bind a 1 lpHSDl or
MR by monitering its concentration variation when contacting with the lipHSDl or MR, through
tracking the labeling. For another example, a test compound (labeled) can be evaluated for its ability
to reduce binding of another compound which is known to bind to lipHSDl or MR (i.e., standard
compound). Accordingly, the ability of a test compound to compete with the standard compound for
binding to the 11βHSDl or MR directly correlates to its binding affinity. Conversely, in some other
screening assays, the standard compound is labled and test compounds are unlabeled. Accordingly,
the concentration of the labled standard compound is monitored in order to evaluate the competition
between the standard compound and the test compound, and the relative binding affinity of the test
compound is thus ascertained.
Kits
The present invention also includes pharmaceutical kits useful, for example, in the treatment
or prevention of11βHSDll- or MR-associated diseases or disorders, obesity, diabetes and other
diseases referred to herein which include one or more containers containing a pharmaceutical
composition comprising a therapeutically effective amount of a compound of the invention. Such kits
can further include, if desired, one or more of various conventional pharmaceutical kit components,
such as, for example, containers with one or more pharmaceutically acceptable carriers, additional
containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or
39

WO 2006/053024 PCT/US2005/040550
as labels, indicating quantities of the components to be administered, guidelines for administration,
and/or guidelines for mixing the components, can also be included in the kit.
The invention will be described in greater detail by way of specific examples. The following
examples are offered for illustrative purposes, and are not intended to limit the invention in any
manner. Those of skill in the art will readily recognize a variety of noncritical parameters which can
be changed or modified to yield essentially the same results. The compound of the Examples were
found to inhibitors of 11PHSD1 and/or MR according to one or more of the assays provided herein.

diazaspiro[4.5]decan-l-one

Step 1. Benzyl (5R)-2-(trans-4-hydroxycyclohexyl)-l-oxo-2,7-diazaspiro[4.5]decane-7-carboxylate
A mixture of 1-benzyl 3-ethyl 3-(2-oxoethyl)piperidine-l,3-dicarboxylate (1.0 g, 0.0030 mol,
prepared by using procedures analogous to those described for the synthesis of example 1, steps 1 and

mol) in 1,2-dichloroethane (8 mL, 0.1 mol) was stirred at rt for 30 min. To the mixture was added
sodium triacetoxyborohydride (1.6 g, 0.0075 mol) and the resulting mixture was stirred at rt for 1 h.
The reaction mixture then was warmed to 80 °C with stirring for 16 h. After cooling to ambient
temperature, the reaction mixture was diluted with dichloromethane and the solution was washed with
IN HC1, water, brine, and dried over MgSC>4. After filtration, the filtrate was concentrated in-vacuo
and the resulting residue was purified by flash column chromatography to afford 1.04 g of the desired
product. Further purification by chiral HPLC led to the isolation of both diastereoisomers. The first-
peak to elute was assigned the S configuration and the second peak was assigned as the R
configuration. LC-MS: 387.3 (M+H)+.
Step 2. Benzyl (5R)-l-oxo-2-{lrans-4-[(triethylsilyl)oxy]cyclohexyl}-2,7-diazaspiro[4.5]decane-7-
carboxylate

carboxylate (2.0 g, 0.0052 mol) in JV.Af-dimethylformamide (5 mL, 0.06 mol) were added 1H-
imidazole (0.986 g, 0.0145 mol) and chlorotriethylsilane (1.13 mL, 0.00673 mol) at rt. After stirring
for 2 h ice-water was added and the resulting mixture was stirred at room temperature for 30 minutes
and extracted three times with AcOEt. The combined extracts were washed with brine, dried over
sodium sulfate, and concentrated. The residual oil was purified by column chromatography using
30% by volume AcOEt in hexanes.

Pd/C, and the suspension was stirred at rt under a H2 balloon for 1.5 h. The inorganics were filtered
and the filtrate was concentrated to afford the desired product.
Step 4. (5R)-7-[2-chloro-5-(trifluoromethyl)phenyl]-2-(trans-4-hydroxycyclohexyl)-2,7-
diazaspiro[4.5]decan-l-one
A mixture of aryl bromide, tris(dibenzylideneacetone)dipalladium(0) (2 mg, 0.000002 mol),
2'-(dicyclohexylphosphino)-N,N-dimethylbiphenyl-2-amine (5 mg, 0.00001 mol) in 1,4-dioxane (0.5
mL, 0.006 mol) was stirred under N2 (g) for 20 min. To this were added (5R)-2-{trans-4-
[(triethylsilyl)oxy]cyclohexyl}-2,7-diazaspiro[4.5]decan-l-one (30 mg, 0.00008 mol) and sodium
te/'/-butoxide (11.8 mg, 0.000123 mol), and the resulting mixture was degassed and stirred at 100 °C
for 16 h. At this time 1M TBAF in THF (0.3 mL) was added dropwise to the reaction mixture and the
solution was stirred at rt for 1 h. The volatiles were removed in-vacuo and the residue was purified by
prep-I-IPLC to afford the desired product. LC-MS: 431.1 (M+H)+.

Example A
Enzymatic assay of 110HSD1
All in vitro assays were performed with clarified lysates as the source of lipHSDl activity.
HEK-293 transient transfectants expressing an epitope-tagged version of full-length human 11(3HSD1
were harvested by centrifugation. Roughly 2 x 107 cells were resuspended in 40 mL of lysis buffer
(25 mM Tris-HCl, pH 7.5, 0.1 M NaCl, 1 mM MgCl2 and 250 mM sucrose) and lysed in a
microfluidizer. Lysates were clarified by centrifugation and the supernatants were aliquoted and
frozen.
298

WO 2006/053024 PCT/US2005/040550
Inhibition of 11βHSDl by test compounds was assessed in vitro by a Scintillation Proximity
Assay (SPA). Dry test compounds were dissolved at 5 mM in DMSO. These were diluted in DMSO
to suitable concentrations for the SPA assay. 0.8 \xL of 2-fold serial dilutions of compounds were
dotted on 384 well plates in DMSO such that 3 logs of compound concentration were covered. 20 \\L
of clarified lysate was added to each well. Reactions were initiated by addition of 20 \\L of substrate-
cofactor mix in assay buffer (25 mM Tris-HCl, pH 7.5, 0.1 M NaCl, 1 mM MgCl2) to final
concentrations of 400 \xM NADPH, 25 nM 3H-cortisone and 0.007% Triton X-100. Plates were
incubated at 37 °C for one hour. Reactions were quenched by addition of 40 uL of anti-mouse coated
SPA beads that had been pre-incubated with 10 |J.M carbenoxolone and a cortisol-specific monoclonal
antibody. Quenched plates were incubated for a minimum of 30 minutes at RT prior to reading on a
Topcount scintillation counter. Controls with no lysate, inhibited lysate, and with no mAb were run
routinely. Roughly 30% of input cortisone is reduced by lipHSDl in the uninhibited reaction under
these conditions.
Test compounds having an IC50 value less than about 20 uM according to this assay were
considered active.
Example B
Cell-based assays for HSD activity
Peripheral blood mononuclear cells (PBMCs) were isolated from normal human volunteers
by Ficoll density centrifugation. Cells were plated at 4x105 cells/well in 200 JJL of AIM V (Gibco-
BRL) media in 96 well plates. The cells were stimulated overnight with 50 ng/ml recombinant human
IL-4 (R&D Systems). The following morning, 200 nM cortisone (Sigma) was added in the presence
or absence of various concentrations of compound. The cells were incubated for 48 hours and then
supernatants were harvested. Conversion of cortisone to cortisol was determined by a commercially
available ELISA (Assay Design).
Test compounds having an IC50 value less than about 20 uM according to this assay were
considered active.
Example C
Cellular assay to evaluate MR antagonism
Assays for MR antagonism were performed essentially as described (Jausons-Loffreda et al. J
Biolumin and Chemilumin, 1994, 9: 217-221). Briefly, HEK293/MSR cells (Invitrogen Corp.) were
co-transfected with three plasmids: 1) one designed to express a fusion protein of the GAL4 DNA
binding domain and the mineralocorticoid receptor ligand binding domain, 2) one containing the
GAL4 upstream activation sequence positioned upstream of a firefly luciferase reporter gene (pFR-
LUC, Stratagene, Inc.), and 3) one containing the Renilla luciferase reporter gene cloned downstream
299

WO 2006/053024 PCT/US2005/040550
of a thymidine kinase promoter (Promega). Transfections were performed using the FuGENE6
reagent (Roche). Transfected cells were ready for use in subsequent assays 24 hours post-
transfection.
In order to evaluate a compound's ability to antagonize the MR, test compounds are diluted in
cell culture medium (E-MEM, 10% charcoal-stripped FBS, 2 mM L-glutamine) supplemented with 1
nM aldosterone and applied to the transfected cells for 16-18 hours. After the incubation of the cells
with the test compound and aldosterone, the activity of firefly luciferase (indicative of MR agonism
by aldosterone) and Renilla luciferase (normalization control) were determined using the Dual-Glo
Luciferae Assay System (Promega). Antagonism of the mineralocorticoid receptor was determined
by monitoring the ability of a test compound to attenuate the aldosterone-induced firefly luciferase
activity.
Compounds having an IC5o of 100 |_iM or less were considered active.
