Description

AUSTRALIA Regulation 3.2 Patents Act 1990 Complete Specification Standard Patent APPLICANT: High Point Pharmaceuticals, LLC Invention Title: BENZAZOLE DERIVATIVES, COMPOSITIONS, AND METHODS OF USE AS B-SECRETASE INHIBITORS The following statement is a full description of this invention, including the best method of performing it known to me: WO 2006/099379 PCT/US2006/009049 TITLE Benzazole Derivatives, Compositions, and Methods of Use as p-Secretase Inhibitors STATEMENT OF RELATED APPLICATION The present application claims the benefit of priority of US Provisional Application 5 No. 60/661,349, filed March 14, 2005. FIELD OF INVENTION The present invention relates to benzazole derivatives useful as inhibitors of secretase, the p-site amyloid precursor protein-cleaving enzyme (BACE). BACKGROUND 10 Alzheimer's disease is characterized by the abnormal deposition of p-amyloid (AP) in the brain in the form of extra-cellular plaques and intra-cellular neurofibrillary tangles. The rate of amyloid accumulation is a combination of the rates of AP formation, aggregation and egress from the brain. It is generally accepted that the main constituent of amyloid plaques is the 4kD amyloid protein (pA4, also referred to as AfP, p-protein and PAP) which is a 15 proteolytic product of a precursor protein of much larger size. Amyloid precursor protein (APP) is a 695-770 amino acid glycoprotein, expressed in the neurons and glial cells in peripheral tissues. APP has a receptor-like structure with a large ectodomain, a membrane spanning region, and a short cytoplasmic tail. Al is a 39-42 amino acid peptide, constitutes part of the ectodomain of APP, and extends partly to the 20 transmembrane domain of APP. At least two secretory mechanisms exist which release APP from the membrane and generate soluble, truncated forms of APP (sAPP). Proteases that release APP and its fragments from the membrane are termed "secretases." Most sAPP is released by a putative a-secretase that cleaves within the As protein to release sAPPa and precludes the release of 25 intact Ap. A smaller portion of sAPP is released by a P-secretase that cleaves near the NHl 2 terminus of APP and produces COOH-terminal fragments (CTFs) which contain the complete AP domain. Thus, the activity of p-secretase or p-site amyloid precursor protein-cleaving enzyme ("BACE") leads to the abnormal cleavage of APP, production of AP, and accumulation of 30 p-amyloid plaques in the brain, which is characteristic of Alzheimer's disease. In addition, the processing of APP by p-secretase is thought to be the rate determining step in Af production. Therefore, therapeutic agents that can inhibit BACE may be useful for the treatment of Alzheimer's disease. 1 WO 2006/099379 PCT/US2006/009049 The compounds of the present invention may be useful for treating Alzheimer's disease by inhibiting the activity of the BACE, thus preventing or reducing the rate of formation of insoluble Af. SUMMARY OF THE INVENTION 5 The present invention is directed to benzazole compounds that inhibit P-site ainyloid precursor protein-cleaving enzyme (BACE) and that may be useful in the treatment or prevention of diseases in which BACE is involved, such as Alzheimer's disease.

BACE Fluorescence Resonance Energy Transfer (FRET) Assay 20 In the following assay, the proteolytic activity of BACE is measured by observing cleavage of a fluorescent group from a peptide substrate containing a rhodamine fluorescent donor and a quenching acceptor. The inhibitory activity of compounds of Formula (I) is compared to a statine derived control inhibitor STA200 (KTEEISEVN(Statine)VAEF-OH, MP Biomedical Cat. # STA 228 WO 2006/099379 PCT/US2006/009049 200). The cleavage reaction occurs when a BACE-I substrate (Rhodamine-EVNLDAEFK Quencher, Invitrogen, Cat.# P2947) was added to a reaction mixture containing BACE-i and allowed to proceed for one hour. Fluorescence, used as a marker of BACE activity, is monitored using 540 rim excitation and 585 inm emission wavelengths (Envision, Perkin 5 Elmer). A typical assay reaction contains BACE- in assay buffer (50 mM sodium acetate, pH 4-4.5, 0.0125% CHAPS (3-[(3-Cholamidopropyl)dimethylammonio)-1-propanesulfonate), 0.0125% TritonX-100, 0.006% EDTA) which is pre-incubated for 30 minutes with test compound in 7.5% DMSO. The reaction is initiated with the addition of BACE- 1 substrate 10 in assay buffer and allowed to proceed for one hour at room temperature. Assays are conducted in black 384-well microtiter plates and scanned at room temperature using 540 nm excitation and 585 nrm emission wavelengths. A test compound's activity is reported as the ICSO. Compounds in Examples 1-501 inhibited the proteolytic activity of BACE in the FRET assay with an IC 50 of less than 30 pM. 15 AB Cell Based Assay Procedure In the following assay, the proteolytic activity of BACE in cells exposed to varying concentrations of a compound of interest is measured by observing the amount of A 1 o secreted from HEK293 cells (Human Embryonic Kidney epithelial cell line) stably expressing either wildtype human APP695 protein (HEK-APPwt cells). 20 HEK-APPwt cells were grown in high glucose DMEM (Dulbecco's Modified Eagles Medium) with 4500 mg glucose/L,L-glutamine, NaH-C0 3 , pyrdoxin HC1, 10 mM HEPES (4 (2-hydroxyethyl)-1-piperazineethanesulfonic acid) (pH 7.4), 0.1 mM NEAA (Non-essential Amino Acids) (GIBCO Cat#i 1140-050), 10% fetal bovine serum and 250 pg/ml hygromycin in T-225 flasks at 37 0 C with CO 2 and humidity control. 25 Test compounds were initially prepared in DMSO and diluted with DMEM media containing 2% PBS (Fetal bovine serum) and 0.05% Tween20. Ten standard compound solutions were prepared having a range of concentrations. The standard compound solutions were used to determine the EC 50 of the test compound. The range of concentrations chosen may depend on the compound's predicted potency. 30 To prepare the cells for the assay, a flask containing HEK-APPwt cells were trypsinized briefly (1 mL trypsin), and once the cells detached, 4 mL of 10% FBS-DMEM was added to the flask. The detached cells were centrifiged at 900 rpm for 5 min to form a pellet. 229 WO 2006/099379 PCT/US2006/009049 The HEK-APPwt cell pellet was re-suspended with 10 mL DMEM media containing 2% FBS. 80 gL of the cell suspension was added to each well of a 96-well cell culture plate to give 100,000 cells/well. 10 gL of a standard compound solution was added to each well of the 96-well cell culture plate followed by 10 pL of Alamar blue solution. The cells were 5 incubated at room temperature for 1 hi, followed by a five-hour incubation in the CO 2 incubator at 37* C. At the end of the incubation, the plates were removed from incubator, and the supernatant was collected. Ap13-4 concentration in the medium was measured by using a commercial AP 1

.

4 0 ELISA kit (IBL, Japan). Briefly, the ELISA plates were coated with anti 10 human Ap 35 -o mouse IgG monoclonal antibody. A horseradish peroxidase enzyme conjugated anti-human AP1 1-28 mouse IgG monoclone antibody was used for detection. The cell culture supernatant was diluted 1:4 fold with (EIA buffer + Protease inhibitor (buffer containing Protease Inhibitor (I mL PI/ 30 mL buffer). A 100 pL aliquot of the diluted supernatant was added to each well of the ELISA plate and incubated for 6 hrs at 4 0 C. The 15 ELISA plate was washed 8 times with phosphate buffered saline (PBS) containing 0.05% Tween 20. A 100 pL of detection antibody was then added and incubated for 1 hour at 4 0 C. The plate was washed 8 times with PBS buffer containing 0.05% Tween 20 followed by addition of 100 iL of the substrate with the chromogen tetramethyl benzidine (TMB). The plate was 20 incubated in the dark at room temperature for about 30 min and a stop solution (IN H2SO4) was added. The intensity of the color developed was measured at 450 nrm. The optical density at 450 nm (OD450) is proportional to the concentration of human Ap iA secreted by the cell. As a reference, N-[N-(3,5-difluorophenacetyl-L-alanyl)]-S-phenylglycine t-butyl ester 25 (DAPT, a y-secretase inhibitor) was used to indicate 100% inhibition of BACE activity. Thus, the assay measures the ability of a compound of interest to reduce ApIAo secretion. Compound potency was reported as the ECSO by calculating the percent inhibition at all concentration levels and the data were fit with non-linear curve fitting algorithm using in GraphPad Prism. 30 Various compounds of the present invention including the compounds of Examples 58, 140, 155, 165, 176, 193, 198, 212, 247, 289, 294, 295, 296,300, 311,312, 318, 343, 351, 355, 414, 416, 417, 428, 434, 439, 458, 472, and 491 exhibited an EC 50 value of less than or equal to 2.0 pM in the cell based assay described above. 230 While the invention has been described and illustrated with reference to certain embodiments thereof, those skilled in the art will appreciate that various changes, modifications and substitutions can be made therein without departing from the spirit and scope of the invention.
