This application claims the benefit of US Patent Application No. 60/387,690,
filed June 11,2002, which is incorporated by reference herein.
BACKGROUND OF THE INVENTION
This invention relates to small molecular compounds which inhibit beta
amyloid production and have utility in the treatment of Alzheimer's disease.
Alzheimer's Disease (AD) is the most common form of dementia (loss of
memory) in the elderly. The main pathological lesions of AD found in the brain
consist of extracellular deposits of beta amyloid protein in the form of plaques and
angiopathy and intracellular neurofibrillary tangles of aggregated
hyperphosphorylated tau protein. Recent evidence has revealed that elevated beta
amyloid levels in the brain not only precede tau pathology but also correlate with
cognitive decline. Further suggesting a causative role for beta amyloid in AD, recent
studies have shown that aggregated beta amyloid is toxic to neurons in cell culture
and has a detrimental effect on memory. This suggests that reducing beta amyloid
levels is a viable therapeutic strategy for the treatment of AD.
Beta amyloid protein is composed mainly of 39 to 42 amino acid peptides and
is produced from a larger precursor protein called amyloid precursor protein (APP) by
the sequential action of the proteases beta and gamma secretase. Although rare, cases
of early onset AD have been attributed to genetic mutations in APP that lead to an
overproduction of either total beta amyloid protein or its more aggregation-prone 42
amino acid isoform. Furthermore, people with Down's Syndrome possess an extra
chromosome that contains the gene that encodes APP and thus have elevated beta
amyloid levels and invariably develop AD later in life.
There continues to be a need for compositions useful in inhibiting beta
amyloid production and in the prevention and treatment of Alzheimer's Disease.

prepared using the methods described below, together with synthetic methods known
in the synthetic organic arts or variations of these methods by one skilled in the art.
See, generally, Comprehensive Organic Synthesis, "Selectivity, Strategy & Efficiency
in Modern Organic Chemistry", ed., I. Fleming, Pergamon Press, New York (1991);
Comprehensive Organic Chemistry, "The Synthesis and Reactions of Organic
Compounds", ed. J.F. Stoddard, Pergamon Press, New York (1979). Preferred
methods include, but are not limited to, those outlined below.
In certain embodiments, it may be desirable to utilize chirally pure α-amino
acids, 1,2-aminoalcohols, N-sulfonyl α-amino acids, and N-sulfonyl 1,2-
aminoalcohols in the reactions described herein for the production of the
phenylsulfonamides of the invention. A number of methods for producing these
compounds are known in the art. Among desirable methodologies are those described
in US Patent Application No. 60/339,264, filed December 11, 2001, and later filed as
US Patent Application No. 10/304,322 and International Patent Application
PCT/US02/38119, both filed November 26, 2002, "Process for the Synthesis of
Chirally Pure α-Amino-Alcohols"; US Patent Application No. 10/014,304, filed
December 11, 2001, entitled "Heterocyclic Sulfonamide Inhibitors of Beta Amyloid
Production", published as US-2002-0183361-A on December 5, 2002; and US Patent
Application No. 10/166,896, filed June 11, 2002 and later published January 16, 2003
as US-2003-0013892-A1, entitled "Production of Chirally Pure α-Amino Acids and
N-Sulfonyl α-Amino Acids".
A first method of preparation for the compounds of the invention consists of
reaction of a 1,2-aminoalcohol II with the appropriate sulfonyl halide in the presence
of a base such as triethylamine (TEA) and in a suitable solvent to afford compounds
of formula III. For compounds where R9 and R10 are hydrogen, oxidation of the N-

sulfonyl primary alcohol with pyridinium chlorochromate (PCC) or under Swem
conditions then affords the corresponding aldehyde IV which can be reacted with
Grignard reagents to afford the secondary alcohols V as a mixture of diastereomers
which can be separated by high performance liquid chromatography (HPLC) or other
suitable methods (Scheme 1).

A second method of preparation involves reaction of an a-amino acid or ester
DC with the appropriate sulfonyl halide in the presence of a base such as triethylamine
and in a suitable solvent to afford compounds of formula X (Scheme 2). The
intermediate N-sulfonyl acid X (Rx=H) can be converted to the corresponding
primary alcohol VIII (R9=R10=H) utilizing standard methodology such as LiAIH4
(LAH), B2H6 or cyanuric chloride/NaBH4. The intermediate N-sulfonyl ester X
(Rx=alkyl, Bn) can also be reduced to the corresponding primary alcohol VIII
utilizing standard methodology such as LiAIH4. Alternatively, the intermediate N-
sulfonyl ester X (Rx=alkyl, Bn) can be converted to the aldehyde IV with diisobutyl
aluminumhydride (DiBAL). Finally, the intermediate N-sulfonyl ester X (Rx=alkyl,
Bn) can be reacted with 2 equivalents of Grignard reagent to afford the tertiary
alcohols HI with R9=R10. Alternatively, for tertiary alcohols III with R9 not equal to

R10, the corresponding Weinreb amide (see Scheme 7) of the N-sulfonyl acid can be
prepared and subsequently reacted with R9MgX and R10MgX.

In a variation of the second method to prepare the primary alcohols, an α-
amino acid or ester (or N-protected derivative thereof) VI is first converted to the
corresponding primary 1,2-aminoalcohol VII (using the methodology outlined in the
previous paragraph), which is subsequently, after deprotection (if necessary), reacted
with the appropriate sulfonyl halide (Scheme 3) to afford compounds of formula VIII.


For the preparation of compounds derived from unnatural a-amino acids
containing beta branching in the amino acid side chain, a method of preparation based
on the work of Hruby (Tet. Lett. 38: 5135-5138 (1997)), incorporated by reference, is
outlined in Scheme 4. This route entails formation of the α, β-unsaturated amide XII
of the Evans chiral auxiliary from an α,β-unsaturated acid XI, followed by conjugate
addition of an organocuprate, trapping of the resulting enolate anion XIII with N-
bromosuccinimide (NBS), displacement of the bromide XIV with azide anion to
afford XV, followed by reduction to the 1,2-aminoalcohol and subsequent
sulfonylation to afford the target compound XVI.


For the preparation of N-alkylated sulfonamides XVII (R6 can be alkyl,
substituted alkyl, allyl, substituted allyl, benzyl, or substituted benzyl), the
sulfonamide ester X can be N-alkylated by either treatment with a suitable base such
as sodium hydride followed by the alkylating agent R6X or by employing Mitsunobu
conditions (R6OH/DEAD, TPP). LiBH4 reduction of the N-alkylated sulfonamide
ester affords the N-alkylated sulfonamide in the primary alcohol series XVII (Scheme
5). These primary alcohols XVII can be converted to N-alkylated analogs of the
secondary alcohols V or aldehyde IV series by chemistry that has been outlined
above. Alternatively, the N-alkylated sulfonamide esters, or their corresponding
Weinreb amides, can be treated with Grignard reagents to afford the N-alkylated
analogs of the tertiary alcohols III (where R9 and R10 are non-hydrogen).

As previously noted (Scheme 1), the preparation of sulfonamides derived from
1,2-arrJnoalcohols in the secondary alcohol series V results in the formation of a
diastereomeric mixture. An alternate method of preparation of these compounds that
results in the production of a pure diastereomer is outlined in Scheme 7 for
compounds derived from L-isoleucine. This method which utilizes chemistry
previously employed by Ronx (Tetrahedron 50: 5354-5360 (1994)), consists of
addition of Grignard reagents to the Weinreb amide XXIII (derived from the requisite
a-amino acid) followed by stereospecific reduction of the ketone XXIV to afford a
single diastereomeric N-protected 1,2-aminoalcohol XXV. Deprotection of this
compound followed by reaction with sulfonyl chlorides affords the pure
diastereomeric sulfonamide secondary alcohols of formula XXVI.

Where catalysts or solvents are included in a reaction step of this invention, it
is expected that other catalysts or solvents known in the art, but not mentioned herein,
can be used. Those skilled in the art will readily be able to determine suitable

catalysts, solvents and reaction conditions for each reaction step included in the
invention.
The invention includes certain types of reactions, such as enolate trapping,
hydrolysis, and reduction reactions that are generally known in the art, but previously
had not been applied in the novel manner of the present invention. Variations in the
specific methods of accomplishing individual steps of the invention can be apparent to
those in the art. Although ail of these possible variations cannot be set forth herein,
such variations are contemplated to be within the scope of the present invention.

An alternate preparation of sulfonamides derived from unnatural 1,2-
aminoalcohols utilizes the Bucherer modification of the Strecker α-amino acid
synthesis (Scheme 6). In this route, an aldehyde XVHI is reacted with cyanide anion

Example 278 - Repressor Release Assay (RRA)
The beta amyloid inhibitory activity of the compounds of the present invention
was determined using the Repressor Release Assay (RRA). See, Table 17. A
compound was considered active in RRA if it leads to at least a 1.5 fold increase in
luciferase activity at 10 ug/mL and was non-toxic.
A. Cell Culture
CH0-K1 cells were cultured in whole DMEM media (DMEM - High
Glucose with 10% fetal bovine serum, 1% Non-essential Amino Acids, and 1%

Penicillin-Streptomycin) at 37°C with 5% CO2. Two million cells were plated into
10-cm dishes 24 hrs prior to transfection.
Transient transfections were completed as recommended by Gibco
BRL using their Lipofectamine Plus system. First, 6 µg of pRSVO-luc and 6 µg of
APP-1acI construct DNA were added to 460 µL Opti-Mem transfection media and
incubated with 30 µL Plus reagent for 15 minutes. Then, a lipid mixture of 40 µL
Lipofectamine reagent and 460 µL Opti-Mem transfection media was incubated with
the DNA-Plus reagent mixture for 15 minutes. During the DNA-lipid incubation, the
CHO-K1 cells were washed once and covered in 5.0 mL DMEM media without
Penicillin-Streptomycin. The DNA-lipid preparation was then layered onto these
cells and incubated at 37°C overnight.
One and one half million transfected cells per well (100 µL total
volume) were plated into sterile, opaque Packard 96-well Culture-Plates in clear
DMEM whole media (DMEM - without phenol red) and incubated at 37°C with 5%
CO2 for 3-5 hours.
B. Compound Dilution
Compounds were diluted using two different protocols; one protocol
was used for compounds supplied neat (weighed powder in vial) and the other
protocol was used for compounds supplied in solution (20 mM in DMSO in 96-well
plates). For both protocols. 25 mM Hepes and 25 mM Hepes/1% DMSO were
prepared fresh to be used as diluent. The Hepes/DMSO was used as the diluent
control on all experimental plates.
The following table depicts the steps for compound dilution (please
note that the last step was the addition of compound to cells/media in tissue culture
plate).


Because some compounds were present in 96-well format, at 20 mM, the
following represents the protocol for their dilution (note that an average molecular
weight of these compounds was used to calculate these cilutions and as above, the last
step was the addition of compound to cells/media in tissue culture plate).

Once the compounds were diluted, they were applied ir duplicate on
cells in tissue culture plates (prepared above). Cells were incubated with compound
at 37°C with 5% CO2 for an additional 36-48 hours.
C. Assay Measurement
Luciferase assays (LucLite reagent, Packard) were performed and were
read on a Packard TopCount instrument. Media was removed from each 96-well plate
and replaced with 100 µL PBS per well (with Mg2+ and Ca2+). An equal volume (100
µL) of the LucLite lysis/substrate buffer was added to each well and the plates were
sealed and mixed in the dark on a rotary shaker for 15-30 minutes at room
temperature. Luciferase readings were then taken on the TopCount instrument.

Measurements were expressed as relative light units (RLU) and are calculated and
analyzed in MS Excel as follows:
D. Analysis of data
"Fold Increase" refers to the amount of luciferase activity (measured in
relative light units) over diluent control. "SEM" refers to the standard error of the
mean for fold increase. "Activity": A compound is considered active if it results in at
least a 1.5 fold increase in luciferase activity at 10 µg/µL. 1=non-toxic, 0=toxic in
Table 17. "Toxicity" is determined by loss of signal (≤ 0.75 fold increase).
E. Standard beta amyloid inhibitor
The reference gamma secretase inhibitor DAPT (LY374973,
AN37124: Dovey, H.F. et al, J. Neurochem. 76: 173-181 (2001)) was prepared as
outlined in WO 98/22494 and tested in RRA and exhibited a 6.0-28.1 fold increase in
luciferase activity at 20 µg/mL.
