TECHNICAL FIELD OF THE INVENTION
[002] The present invention relates to modulators of muscarinic receptors. The present invention
also provides compositions comprising such modulators, and methods therewith for treating
muscarinic receptor mediated diseases.
BACKGROUND OF THE INVENTION
[003] The neurotransmitter acetylcholine binds to two types of cholinergic receptors: the
ionotropic family of nicotinic receptors and the metabotropic family of muscarinic receptors.
Muscarinic receptors belong to the large superfamily of plasma membrane-bound G protein
coupled receptors (GPCRs). To date, five subtypes of muscarinic receptors (M1-M5) have been
cloned and sequenced from a variety of species, and show a remarkably high degree of homology
across species and receptor subtype. These M1-M5 muscarinic receptors are predominantly
expressed within the parasympathetic nervous system which exerts excitatory and inhibitory control
over the central and peripheral tissues and participate in a number of physiologic functions,
including heart rate, arousal, cognition, sensory processing, and motor control.
[004] Muscarinic agonists such as muscarine and pilocarpine, and antagonists, such as atropine
have been known for over a century, but little progress has been made in the discovery of receptor
subtype-selective compounds, thereby making it difficult to assign specific functions to the
individual receptors. See, e.g., DeLapp, N. et ah, "Therapeutic Opportunities for Muscarinic
Receptors in the Central Nervous System," J. Med. Chem., 43(23), pp. 4333-4353 (2000); Hulme,
E. C. etal., "Muscarinic Receptor Subtypes," Ann. Rev. Pharmacol. Toxicol, 30, pp. 633-673
(1990); Caulfield, M. P. et ah, "Muscarinic Receptors-Characterization, Coupling, and Function,"
Pharmacol. Ther., 58, pp. 319-379 (1993); Caulfield, M. P. et al, International Union of
Pharmacology. XVII. Classification of Muscarinic Acetylcholine Receptors," Pharmacol. Rev., 50,
pp. 279-290 (1998), the disclosures of which are incorporated herein by reference.
[005] The Muscarinic family of receptors is the target of a large number of pharmacological
agents used for various diseases, including leading drugs for COPD, asthma, urinary incontinence,
glaucoma, Alzheimer's (AchE inhibitors). Despite the large therapeutic value of this family,
cholinergic drugs are limited by the lack of selectivity of these agents, with significant activation of
the parasympathetic autonomous system and elevated incidence of adverse effects. The molecular
cloning of the muscarinic receptors and the identification of the physiological role of specific

isoforms using knock-out mice, nas recently delineated novel opportunities for selective muscarinic
ligands, and has helped to define the selectivity profile that is required for enhanced efficacy and
reduced side effects.
[006] There is a need for modulators of muscarinic receptors M1-M5. There is also a need for
methods for treating muscarinic receptor-mediated diseases.
[007] There is also a need for modulators of muscarinic receptors that are selective as to
subtypes M1-M5.

DETAILED DESCRIPTION OF THE INVENTION
[022] As used herein, the following definitions shall apply unless otherwise indicated.
I. DEFINITIONS

[023] As used herein, the following definitions shall apply unless otherwise indicated, for
purposes of this invention, the chemical elements are identified in accordance with the Periodic
Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75th Ed. Additionally,
general principles of organic chemistry are described in "Organic Chemistry", Thomas Sorrell,
University Science Books, Sausolito: 1999, and "March's Advanced Organic Chemistry", 5th Ed.,
Ed.: Smith, M.B. and March, J., John Wiley & Sons, New York: 2001, the entire contents of which
are hereby incorporated by reference.
[024] The term "muscarinic receptor," without a prefix specifylng the receptor subtype, refers to
one or more of the five receptor subtypes M1-M5.
[025] The term "modulating" as used herein mean's increasing or decreasing, e.g. activity, by a
measurable amount. Compounds that modulate muscarinic activity by increasing the activity of the
muscarinic receptors are called agonists. Compounds that modulate muscarinic activity by
decreasing the activity of the muscarinic receptors are called antagonists. An agonist interacts with
a muscarinic receptor to increase the ability of the receptor to transduce an intracellular signal in
response to endogenous ligand binding. An antagonist interacts with a muscarinic receptor and
competes with the endogenous ligand(s) or substrate(s) for binding site(s) on the receptor to
decrease the ability of the receptor to transduce an intracellular signal in response to endogenous
ligand binding.
[026] The phrase "treating or reducing the severity of a muscarinic receptor mediated disease"
refers both to treatments for diseases that are directly caused by muscarinic activities and
alleviation of symptoms of diseases not directly caused by muscarinic activities. Examples of

[079] In general, the term "substituted," whether preceded by the term "optionally" or not, refers
to the replacement of hydrogen radicals in a given structure with the radical of a specified
substituent. Specific substituents are described above in the definitions and below in the
description of compounds and examples thereof. Unless otherwise indicated, an optionally
substituted group may have a substituent at each substitutable position of the group, and when more
than one position in any given structure may be substituted with more than one substituent selected
from a specified group, the substituent may be either the same or different at every position. A ring
substituent, such as a heterocycloalkyl, may be bound to another ring, such as a cycloalkyl, to form
a spiro-bicyclic ring system, e.g., both rings share one common atom. As one of ordinary skill in
the art will recognize, combinations of substituents envisioned by this invention are those
combinations that result in the formation of stable or chemically feasible compounds.
[080] The phrase "stable or chemically feasible," as used herein, refers to compounds that are not
substantially altered when subjected to conditions to allow for their production, detection, and
preferably their recovery, purification, and use for one or more of the purposes disclosed herein. In
some embodiments, a stable compound or chemically feasible compound is one that is not
substantially altered when kept at a temperature of 40 °C or less, in the absence of moisture or other
chemically reactive conditions, for at least a week.
[081] As used herein, an effective amount is defined as the amount required to confer a
therapeutic effect on the treated patient, and is typically determined based on age, surface area,
weight, and condition of the patient. The interrelationship of dosages for animals and humans
(based on milligrams per meter squared of body surface) is described by Freireich et al., Cancer
Chemother. Rep., 50: 219 (1966). Body surface area may be approximately determined from
height and weight of the patient. See, e.g., Scientific Tables, Geigy Pharmaceuticals, Ardsley, New
York, 537 (1970). As used herein, "patient" refers to a mammal, including a human.
[082] Unless otherwise stated, structures depicted herein are also meant to include all isomeric
(e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for
example, the R and S configurations for each asymmetric center, (Z) and (E) double bond isomers,
and (Z) and (E) conformational isomers. Therefore, single stereochemical isomers as well as
enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present
compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of
the compounds of the invention are within the scope of the invention. Additionally, unless
otherwise stated, structures depicted herein are also meant to include compounds that differ only in

tne presence or one or more isotopically enriched atoms, For example, compounds having the
present structures except for the replacement of hydrogen by deuterium or tritium, or the
replacement of a carbon by a 13C- or 14C-enriched carbon are within the scope of this invention.
Such compounds are useful, for example, as analytical tools or probes in biological assays.

available starting materials using methods known in the art. Exemplary synthetic routes to
produce compounds of formulae (I and II), are provided below in Preparations A-F and Schemes
1-10. For simplicity of illustration, schemes 1-10 depict only a single R1 substituent on the
fused phenyl ring of formulae I and II, the compounds of this invention may include 1 to 4 R1
substituents on the fused phenyl ring.
[0155] Scheme 1 below depicts general conditions for the synthesis of compounds of formula

amination conditions (step a), typically using NaBH(OAc)3 in DCE/AcOH/TEA at room
temperature, may be used to provide the desired compounds of formula I. For less reactive
ketones, more forcing conditions may be used. For example, the treatment of the amine (A) and
the ketone in a neat solution of Ti(OiPr)4, followed by treatment with NaBH4 in MeOH, may be
used to provide the desired compounds of formula I. See Abdel-Magid, A.F. et al., "Reductive
Amination of Aldehydes and Ketones with Sodium Triacetoxyborohydride. Studies on Direct

[0175] The present invention includes within its scope pharmaceutically acceptable prodrugs of
the compounds of the present invention. A "pharmaceutically acceptable prodrug" means any
pharmaceutically acceptable salt, ester, salt of an ester, or other derivative of a compound of the
present invention which, upon administration to a recipient, is capable of providing (directly or
indirectly) a compound of this invention or an active metabolite or residue thereof. Preferred
prodrugs are those that increase the bioavailability of the compounds of this invention when
such compounds are administered to a mammal or which enhance delivery of the parent
compound to a biological compartment relative to the parent species.
[0176] The term "pharmaceutically acceptable carrier, adjuvant, or vehicle" refers to a non-toxic
carrier, adjuvant, or vehicle that does not destroy the pharmacological activity of the compound
with which it is formulated. Pharmaceutically acceptable carriers, adjuvants or vehicles that
may be used in the compositions of this invention include, but are not limited to, ion exchangers,
alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer
substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride
mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate,

disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts,
colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances,
polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-
polyoxypropylene-block polymers, polyethylene glycol and wool fat.
[0177] Pharmaceutically acceptable salts of the compounds of this invention include those
derived from pharmaceutically acceptable inorganic and organic acids and bases. Examples of
suitable acid salts include acetate, adipate, alginate, aspartate, benzoate, benzenesulfonate,

picrate, pivalate, propionate, salicylate, succinate, sulfate, tartrate, thiocyanate, tosylate and
undecanoate. Other acids, such as oxalic, while not in themselves pharmaceutically acceptable,
may be employed in the preparation of salts useful as intermediates in obtaining the compounds
of the invention and their pharmaceutically acceptable acid addition salts.
[0178] Salts derived from appropriate bases include alkali metal (e.g., sodium and potassium),
alkaline earth metal (e.g., magnesium), ammonium and N^CM alkyl)4 salts. This invention also
envisions the quaternization of any basic nitrogen-containing groups of the compounds disclosed
herein. Water or oil-soluble or dispersible products may be obtained by such quaternization.
[0179] The compositions of the present invention may be administered orally, parenterally, by
inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir.
The term "parenteral" as used herein includes subcutaneous, intravenous, intramuscular, intra-
articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial
injection or infusion techniques. Preferably, the compositions are administered orally,
intraperitoneally or intravenously. Sterile injectable forms of the compositions of this invention
may be aqueous or oleaginous suspension. These suspensions may be formulated according to
techniques known in the art using suitable dispersing or wetting agents and suspending agents.
The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-
toxic parenterally-acceptable diluent or solvent, for example as a solution in 1,3-butanediol.
Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution
and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally
employed as a solvent or suspending medium.

[0180] For this purpose, any bland fixed oil may be employed including synthetic mono- or di-
glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the
preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or
castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may
also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or
similar dispersing agents that are commonly used in the formulation of pharmaceutically
acceptable dosage forms including emulsions and suspensions. Other commonly used
surfactants, such as Tweens, Spans and other emulsifylng agents or bioavailability enhancers
which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or
other dosage forms may also be used for the purposes of formulation.
[0181] The pharmaceutically acceptable compositions of this invention may be orally
administered in any orally acceptable dosage form including, but not limited to, capsules,
tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly
used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also
typically added. For oral administration in a capsule form, useful diluents include lactose and
dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is
combined with emulsifylng and suspending agents. If desired, certain sweetening, flavoring or
coloring agents may also be added.
[0182] Alternatively, the pharmaceutically acceptable compositions of this invention may be
administered in the form of suppositories for rectal administration. These can be prepared by
mixing the agent with a suitable non-irritating excipient that is solid at room temperature but
liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such
materials include cocoa butter, beeswax and polyethylene glycols.
[0183] The pharmaceutically acceptable compositions of this invention may also be
administered topically, especially when the target of treatment includes areas or organs readily
accessible by topical application, including diseases of the eye, the skin, or the lower intestinal
tract. Suitable topical formulations are readily prepared for each of these areas or organs.
[0184] Topical application for the lower intestinal tract can be effected in a rectal suppository
formulation (see above) or in a suitable enema formulation. Topically-transdermal patches may
also be used.
[0185] For topical applications, the pharmaceutically acceptable compositions may be
formulated in a suitable ointment containing the active component suspended or dissolved in one
or more carriers. Carriers for topical administration of the compounds of this invention include,
but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol,

polyoxyethylene, polyoxypropylene compound, emulsifylng wax and water. Alternatively, the
pharmaceutically acceptable compositions can be formulated in a suitable lotion or cream
containing the active components suspended or dissolved in one or more pharmaceutically
acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan
monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl
alcohol and water.
[0186] For ophthalmic use, the pharmaceutically acceptable compositions may be formulated as
micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in
isotonic, pH adjusted sterile saline, either with or without a preservative such as benzylalkonium
chloride. Alternatively, for ophthalmic uses, the pharmaceutically acceptable compositions may
be formulated in an ointment such as petrolatum.
[0187] The pharmaceutically acceptable compositions of this invention may also be
administered by nasal aerosol or inhalation. Such compositions are prepared according to
techniques well-known in the art of pharmaceutical formulation and may be prepared as
solutions in saline, employlng benzyl alcohol or other suitable preservatives, absorption
promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or
dispersing agents.
[0188] Most preferably, the pharmaceutically acceptable compositions of this invention are
formulated for oral administration.
[0189] The amount of the compounds of the present invention that may be combined with the
carrier materials to produce a composition in a single dosage form will vary depending upon the
host treated, the particular mode of administration. Preferably, the compositions should be
formulated so that a dosage of between 0.01-100 mg/kg body weight/day of the modulator can
be administered to a patient receiving these compositions.
[0190] It should also be understood that a specific dosage and treatment regimen for any
particular patient will depend upon a variety of factors, including the activity of the specific
compound employed, the age, body weight, general health, sex, diet, time of administration, rate
of excretion, drug combination, and the judgment of the treating physician and the severity of
the particular disease being treated. The amount of a compound of the present invention in the
composition will also depend upon the particular compound in the composition.
[0191] Depending upon the particular condition, or disease, to be treated or prevented,
additional therapeutic agents, which are normally administered to treat or prevent that condition,
may also be present in the compositions of this invention. As used herein, additional therapeutic

[0198] According to an alternative embodiment, the present invention provides a method of
treating or reducing the severity of a disease in a patient, wherein said disease is selected from
pain, psychosis (including schizophrenia, hallucinations, and delusions), Alzheimer's disease,
Parkinson's disease, glaucoma, bradhycardia, gastric acid secretion, asthma, or GI disturbances.
[0199] According to a preferred embodiment, the present invention is useful for treating or
reducing the severity of psychosis, Alzheimer's disease, pain, or Parkinson's disease.

[0202] Sodium bis(trimethylsilyl)amide (6 mmol, 6 mL of 1 M solution in THF) was added to a
suspension of 2.06 g (6.0 mmol) of methoxymethyltriphenylphosphonium chloride in 6 mL of
THF at 0 °C under argon. After stirring at 0 °C for 15 min, the resulting dark red solution was
added via syringe to a solution of 0.79 g (4.0 mmol) of JV-(ethoxycarbonyl)tropinone (6) in 8 mL
of THF at 0 °C and then stirred at room temerature for 4 h (an orange color persisted). The
reaction mixture was quenched by adding sat aq. NaCl (15 mL) and then extracted with ether
(25 mL x 3). The combined organic extracts were dried over Na2SO4. The solid residue
obtained after solvent evaporation was loaded onto a short silica gel column (3.5 cm x 4 cm) to
remove the phosphorous impurities. The product was eluted with ether. After the solvent was
evaporated, the product enol ether was obtained as a brown oil which was used in the next step
without further purification.
[0203] The enol ether intermediate was dissolved in a solution of 12 mL of 2 N HCl and 20 mL
of acetonitrile, and stirred at room temperature for 16 h. After removing the acetonitrile on a
rotary evaporator, the aqueous solution was extracted with ether (25 mL x 3). The combined
organic extracts were washed with sat. aq. NaHCO3 (15 mL x 2), sat. aq. NaCl (15 mL) and then
dried over Na2SO4. After the solution was evaporated to dryness, the residue was purified by
chromatography (SiC>2, 10%-20% EtOAc in Hexane as eluent). iV-(ethoxycarbonyl)-8-aza-
bicyclo[3.2.1]octane-3-carbaldehyde (0.65 g) was obtained as a colorless oil in an approximately

mmol) in DCM (25 mL) was slowly added AICI3 (666 mg, 5 mmol) under argon at -43 °C (dry
ice/isopropanol bath). The reaction mixture was stirred at -43 °C under argon for 30 min, and
then quenched with sat. aq. K2CO3 (50 mL). After the reaction mixture was gradually warmed
to room temperature, it was extracted with ether (200 mL x 5). The combined ether extracts
were washed with sat. aq. K2CO3 (200 mL x 2) and sat. aq. NaCl (200 mL x 2), dried over
MgSO4, filtered, and concentrated to give 2.6 g of oily crude product 7-oxa-bicyclo[2.2.1]hept-
5-ene-2-carbaldehyde which was used in the next step without further purification. See

Functional mobilization of intracellular calcium to determine muscarinic receptor activity:
[0273] CHO cells expressing muscarinic receptors (M1 to Ms) are grown as monolayers in tissue
culture flasks at 37° C in a humidified atmosphere containing 5% CO2 and passaged every 3-5
days. The growth media is Dulbecco's modified eagles medium (DMEM, Gibco Cat# 12430-
054), containing 25 mM Hepes and supplemented with Fetal Bovine Serum (Hyclone, cat#
SH30071.03), 0.1 mM of MEM non-essential amino acids (GIBCO, Cat# 11140-050), 1 mM
MEM Sodium Pyruvate (GIBCO Cat# 11360-070) and 100 units/ml of Penicillin G and 100
/ig/ml of Streptomycin (GIBCO Cat# 15140-122). The recombinant muscarinic receptor cell
lines are grown under antibiotic pressure with media containing 25 /ig/ml zeocin and 500 /Jg/ml
G418 (Ml-CHO), 4 fig/ml puromycin, 50 /ig/ml zeocin and 2.5 /ig/ml blasticidin (M2 and M4-
CHO) or 50 /ig/ml zeocin and 4 jig/ml puromycin (M3 and M5-CHO).
[0274] Cells are harvested at 80-90% confluence using Versene (GIBCO Cat# 15040-066),
collected by centrifugation and seeded 18-24 hrs prior to running the calcium assay at a density
of 5,000-10,000 cells/well in back-walled, clear-bottomed 384-well plates (BD Biocoat, poly-D-
lysine, Cat#356663). The day of the experiment, the cells are washed with a plate washer
(Bioteck Instruments, ELX 405) using bathl buffer (140-mM NaCl, 4.5-mM KCl,2-mM CaCl2,
1-mM MgCk, 10-mM Hepes-Na, 10-mM Glucose, pH 7.4, with NaOH) containing 1 mM
Probenecid. Next, the calcium dye Fluo-3 (25 jd/well of Fluo-3 AM at 4 µM, Molecular Probes
F-1241, in Bath 1 buffer containing 1 mM Probenecid) is added to the 25 µl of Bath 1 remaining
in each well after the plate wash and the dye is loaded at 37°C in the tissue culture incubator for
60-90 min. The fluorescent dye is removed using the plate washer with Bath 1 containing 1 mM
Probenecid, leaving 25 /d/well of this solution after the wash. Alternatively, cells can be loaded
with the calcium indicator from Molecular Devices (Calcium 3 Assay Reagents, Cat # R7181)
adding 5 /tl of a 5X solution dye in Bath 1 containing 1 mM Probenecid (10 ml per dye flask
cat# R7182 to generate a solution 20X) to 20 µl of the same buffer. After loading for 60 min, the
experiment can be run without having to remove the dye.
[0275] Compounds are prepared at a 2x fold concentration in a 96-well plate (round bottom,
Costar Corning cat# 3656), by reconstituting the pre-spotted compounds in bath 1 containing 1
mM probenecid. The final concentration DMSO is 0.5 %, and the amount of DMSO is
normalized across the assay plate. To determine an agonist action of the compounds on
muscarinic receptors, the reconstituted compounds are added (25 µl compound/well) to the cell
assay plate (containing 25 µl/well) using the multi-channel robotic system of the FLIPR 3
Instrument (Molecular Devices, Sunnyvale, CA). To determine a functional inhibitory action of
the compounds on muscarinic receptors, the reconstituted compounds are added (25 µl

compound/well) to the assay plate and pre-incubated for 15 min prior to adding 25 µl of
Carbachol at 3X the EC80 for each muscarinic subtype. Alternatively, the compounds can be
co-applied simultaneously with the agonist. In both assay modes, the fluorescence is recorded
for 60 sec (excitation wavelength is 488 nM and emission wavelength 540 nm) using the FLEPR
3 instrument
[0276] The potency, efficacy and selectivity of the muscarinic compounds were evaluated by
screening the compound activity across the whole family (M1 to M5 cells). Compounds were
also screened for activity on other proteins such as other GPCRs and ion channels to determine
selectivity on M4 receptors.
[0277] The compounds of the present invention were found to modulate the M1 and/or M4
muscarinic receptors selectively over the other receptor types.
[0278] Examples of activities and efficacies of the muscarinic compounds of formulae (I and II)
on modulating M1 and M4 receptors are shown below in Table 2. The compound activity for the
M1 and M4 receptor is illustrated with "xxx" if activity was measured to be less than 0.1 uM,
"xx" if activity was measured to be between 0.1 µM and 1.0 µM, and "x" if activity was
measured to be greater than 1.0 µM. The efficacy for M1 and M4 modulation is illustrated with
"xxx" if efficacy was calculated to be greater than 85 %, "xx" if efficacy was calculated to be
between 85% and 65%, and "x" if efficacy was calculated to be less than 65 %.
