Alpha-(N-sulfonamido)acetamide derivatives as beta-amyloid inhibitors

FIELD OF THE INVENTION

[0002] This invention provides novel α-(N-sulfonamido)acetamide compounds having drug and bio-affecting properties, their pharmaceutical compositions and method of use. In particular, the invention is concerned with α-(N-arylsulfonamido)acetamides. These compounds possess unique inhibition of the β-amyloid peptide (β-AP) production, thereby acting to prevent the accumulation of amyloid protein deposits in the brain. More particularly, the present invention relates to the treatment of Alzheimer's Disease (AD).

BACKGROUND OF THE INVENTION

[0003] Alzheimer's Disease is a progressive, neurodegenerative disorder characterized by memory impairment and cognitive dysfunction. AD is characterized pathologically by the accumulation of senile (neuritic) plaques, neurofibrillary tangles, amyloid deposition in neural tissues and vessels, synaptic loss, and neuronal death. It is the most common form of dementia and it now represents the third leading cause of death after cardiovascular disorders and cancer. The cost of Alzheimer's Disease is enormous (in the U.S., greater than $100 billion annually) and includes the suffering of the patients, the suffering of families, and the lost productivity of patients and caregivers. As the longevity of society increases, the occurrence of AD will markedly increase. It is estimated that more than 10 million Americans will suffer from AD by the year 2020, if methods for prevention and treatment are not found. Currently, AD is estimated to afflict 10% of the population over age 65 and up to 50% of those over the age of 85. No treatment that effectively prevents AD or reverses the clinical symptoms and underlying pathophysiology is currently available (for review see Selkoe, D. J. Ann. Rev. Cell Biol., 1994, 10: 373-403).

[0004] There have been many theories relating to the etiology and pathogenesis of AD. These theories were either based on analogies with other diseases and conditions (e.g., slow virus and aluminum theories), or based on pathologic observations (e.g., cholinergic, amyloid, or tangle theories). Genetic analysis can potentially differentiate between competing theories. The identification of mutations in the β-amyloid precursor protein (β-APP) of individuals prone to early onset forms of AD and related disorders strongly supports the amyloidogenic theories.

[0005] Histopathological examination of brain tissue derived upon autopsy or from neurosurgical specimens in affected individuals reveals the occurrence of amyloid plaques and neurofibrillar tangles in the cerebral cortex of such patients. Similar alterations are observed in patients with Trisomy 21 (Down's syndrome). Biochemical and immunological studies reveal that the dominant proteinaceous component of the amyloid plaque is an approximately 4.2 kilodalton (kD) protein of about 39 to 43 amino acids. This protein is designated Aβ, β-amyloid peptide, and sometimes β/A4; referred to herein as Aβ. In addition to its deposition in amyloid plaques, Aβ is also found in the walls of meningeal and parenchymal arterioles, small arteries, capillaries, and sometimes, venules. Compelling evidence accumulated during the last decade reveals that Aβ is an internal polypeptide derived from a type 1 integral membrane protein, termed β-amyloid precursor protein (APP) (Selkoe, D. Physiol. Rev. 2001, 81, 741-766; Wolfe, M. J. Med. Chem. 2001, 44, 2039-2060). βAPP is normally produced by many cells both in vivo and in cultured cells, derived from various animals and humans. Several proteolytic fragments of APP are generated by proteinases referred to as secretases. A subset of these proteolytic fragments, designated β-amyloid peptide (Aβ), contains 39 to 43 amino acids and is generated by the combined action of β-secretase and γ-secretase. β-secretase is a membrane-bound, aspartyl protease that forms the N-terminus of the Aβ peptide. The C-terminus of the Aβ peptide is formed by γ-secretase, an apparently oligomeric complex that includes presenilin-1 and/or presenilin-2. Presenilin-1 and presenilin-2 are polytopic membrane-spanning proteins that may contain the catalytic components of γ-secretase (Seiffert, D.; Bradley, J. et al. J. Biol. Chem. 2000, 275, 34086-34091).

[0006] Multiple lines of evidence together strongly suggest that a reduction in brain Aβ levels will prevent the onset and progression of AD. First, Aβ is a major constituent of the parenchemyal plaques observed in all AD patients and the cerebral vasculature amyloid deposits observed in 90% AD patients (reviewed in Selkoe, D. Physiol. Rev. 2001, 81, 741-766; Wolfe, M. J. Med. Chem. 2001, 44, 2039-2060). These plaques are formed from the aggregation of soluble Aβ whose brain levels are highly correlated with the severity of AD neurodegeneration (McLean, C., Chemy, R. et al. Ann. Neurol. 1999, 46, 860-866). Second, mutations in three genes (APP, PS-1, or PS-2) that increase Aβ cause familial AD (FAD), where AD onset is accelerated by at least a decade. Included in the mutations that increase Aβ are chromosome 21 Trisomy that causes Down's syndrome. Third, transgenic mice that express one or more of the mutant FAD genes have increased Aβ levels, form parenchymal plaques and cerebral vascular deposits containing Aβ, exhibit memory deficits (Chapman, P.; White, G. et al. Nature Neurosci. 1999, 2, 271-276) and enhance neurofibrillary degeneration in mice that also overexpress mutant tau (Lewis, J.; Dickson, D. et al. Science 2001, 293, 1487-1491). Fourth, Aβ is toxic to cultured cells (Dahlgren, K.; Manelli, A. et al. J. Biol. Chem. 2002 277, 32046-32053), induces neurofibrillary tangles in mice with mutant tau (Gotz, J., Chen, F. et al. Science 2001, 293, 1491-1495) and interferes with long-term potentiation, a likely component of memory (Walsh, D., Klyubin, I. et al. Nature 2002, 416, 535-539 and references therein). Taken together, these data lead one skilled in the art to conclude that excess Aβ production and/or reduced Aβ clearance cause AD. From this it follows that reducing brain Aβ levels by inhibition of γ-secretase will prevent the onset and progression of AD.

[0007] In addition to AD, excess production and/or reduced clearance of Aβ causes cerebral amyloid angiopathy (CAA) (reviewed in Thal, D., Gherbremedhin, E. et al. J. Neuropath. Exp. Neuro. 2002, 61, 282-293). In these patients, vascular amyloid deposits cause degeneration of vessel walls and aneurysms that may be responsible for 10-15% hemorrhagic strokes in elderly patients. As in AD, mutations in the gene encoding Aβ lead to an early onset form of CAA, referred to as cerebral hemorrhage with amyloidosis of the Dutch type, and mice expressing this mutant protein develop CAA that is similar to patients.

[0008] It is hypothesized that inhibiting the production of Aβ will prevent and reduce neurological degeneration, reducing neurotoxicity and, generally, mediating the pathology associated with Aβ production. Methods of treatment could target the formation of Aβ through the enzymes involved in the proteolytic processing of β-amyloid precursor protein. Compounds that inhibit β- or γ-secretase activity, either directly or indirectly, could control the production of Aβ. Advantageously, compounds that specifically target γ-secretases, could control the production of Aβ. Such inhibition of β- or γ-secretases could thereby reduce production of Aβ which, could reduce or prevent the neurological disorders associated with Aβ protein.

[0009] Smith, et al. in International Application WO 00/50391, published Aug. 31, 2000, disclose a series of sulfonamide compounds that can act to modulate production of amyloid β protein as a means of treating a variety of diseases, especially Alzheimer's Disease and other diseases relating to the deposition of amyloid. Japanese Patent No.11343279, published Dec. 14, 1999 discloses a series of sulfonamide derivatives which are TNF-alpha inhbitors useful for treating autoimmune diseases.

[0010] Nothing in these references can be construed to disclose or suggest the novel compounds of this invention and their use to inhibit β-AP production.

SUMMARY OF THE INVENTION

[0011] A series of α-(N-sulfonamido)acetamide derivatives have been synthesized. These compounds specifically inhibit the production of β-amyloid peptide (β-AP) from β-amyloid precursor protein (β-APP). The pharmacologic action of these compounds makes them useful for treating conditions responsive to the inhibition of β-AP in a patient; e.g., Alzheimer's Disease (AD) and Down's Syndrome. Therapy utilizing administration of these compounds to patients suffering from, or susceptible to, these conditions involves reducing β-AP available for accumulation and deposition in brains of these patients.

[0039] or a non-toxic pharmaceutically acceptable salt thereof.

[0040] The present invention also provides a method for the treatment or alleviation of disorders associated with β-amyloid peptide, especially Alzheimer's Disease, which comprises administering together with a conventional adjuvant, carrier or diluent a therapeutically effective amount of a compound of formula I or a nontoxic pharmaceutically acceptable salt, solvate or hydrate thereof.

[0045] As the compounds of the present invention possess an asymmetric carbon atom, the present invention includes the racemate as well as the individual enantiometric forms of the compounds of Formula I as described herein and in the claims. The use of a single designation such as (R) or (S) is intended to include mostly one stereoisomer. Mixtures of isomers can be separated into individual isomers according to methods which are known per se, e.g. fractional crystallization, adsorption chromatography or other suitable separation processes. Resulting racemates can be separated into antipodes in the usual manner after introduction of suitable salt-forming groupings, e.g. by forming a mixture of diastereosiomeric salts with optically active salt-forming agents, separating the mixture into diastereomeric salts and converting the separated salts into the free compounds.

When applied to an individual active ingredient, administered alone, the term refers to that ingredient alone. When applied to a combination, the term refers to combined amounts of the active ingredients that result in the therapeutic effect, whether administered in combination, serially or simultaneously. The terms “treat, treating, treatment” as used herein and in the claims means preventing or ameliorating diseases associated with β-amyloid peptide.

[0048] General Reaction Schemes

[0049] The general procedures used to synthesize the compounds of Formula I are described in Reaction Schemes 1-23. Reasonable variations of the described procedures, which would be evident to one skilled in the art, are intended to be within the scope of the present invention.

[0050] The starting ((α-amino)acetamides of Formula II are used in racemic or in enantiomerically pure form and are commercially available or are prepared by well-known literature procedures from commercially available ((α-amino)acids (general reference for amide preparation.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976; see also Reaction Scheme 18 for the conversion of the acid of Formula XLVIII to the amide of Formula XLIX). The compound of Formula II is treated with a suitable base and a sulfonylating reagent such as a sulfonyl chloride in an aprotic solvent such as CH2Cl2 at room temperature to generate the (α-sulfonamido)acetamide of Formula III. Suitable bases include triethylamine and pyridine.

[0051] In one method for conversion of the compound of Formula III to the sulfonamide of Formula I, the compound of Formula III is treated with a suitable base and an alkylating agent in an aprotic solvent with or without heating. Suitable bases for this reaction include potassium carbonate and cesium carbonate. Alkylating agents include alkyl halides (e.g., alkyl chloride, alkyl bromide, or alkyl iodide) and alkyl sulfonates (tosylates, mesylates, trifluoromethanesulfonates). Preferred solvents include DMF and acetonitrile. The temperature range for the reaction is typically 20° C. to 100° C.

[0052] An alternative method for conversion of the compound of Formula III to the compound of Formula I involves treatment of the compound of Formula III with triphenyl phosphine, a dialkyl azodicarboxylate, and an alcohol in an inert solvent with or without heating.

[0053] The compounds of Formula I can also be prepared using solid phase methodology. For example, FMOC-protected Rink amide resin is treated with piperidine in DMF to effect removal of the FMOC group. The resin is then coupled with an amino-protected (α-amino)acid in the presence of a coupling agent such as 1-hydroxybenzotriazole and a dialkyl carboduimide in an inert solvent such as DMF with or without heating. Deprotection of the α-amino group affords the polymer-bound amide of Formula IV. In the case of an FMOC-protected amino acid, the deprotection can be accomplished by treatment with piperidine in DMF.

[0054] Reaction of the compound of Formula IV with an appropriate base such as pyridine and a sulfonylating agent such as a sulfonyl chloride in an inert solvent provides the resin-linked sulfonamide of Formula V. Alkylation of the compound of Formula V with an alkyl halide (e.g., alkyl chloride, alkyl bromide, or alkyl iodide) or alkyl sulfonate (e.g., mesylate, tosylate, or trifluoromethanesulfonate) is carried out in the presence of a base in an inert solvent at room temperature. A preferred base is 2-t-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diasaphosphorine. Cleavage from the resin provides the sulfonamide of Formula I. In the case of the Rink amide resin, the cleavage is preferably carried out using trifluoroacetic acid in an inert solvent such as CH2Cl2.

[0055] The compounds of Formula I can also be prepared as shown in Reaction Scheme 2. Reductive alkylation of the amine of Formula I to provide the amine of Formula VI is effected by treatment with an aldehyde and a hydride reducing agent in the presence of an acid catalyst with or without heating. A preferred reducing agent is sodium cyanoborohydride. A preferred acid catalyst is a Lewis acid such as ZnCl2. The reaction solvent is preferably methanol. The amine of Formula VI is then treated with a sulfonylating agent such as a sulfonyl chloride in the presence of an amine such as triethylamine. This reaction is carried out in an inert solvent such as CH2Cl2 with or without heating to afford the product of Formula I. The reaction is typically carried out at room temperature.

[0056] Preparation of compounds of Formula VIII is accomplished as shown in Reaction Scheme 3 by reaction of the compound of Formula VII with an amine in the presence of an acid scavenger such as triethylamine in an inert solvent such as CH2Cl2 with or without heating. The compound of Formula VII is prepared by the sequence shown in Reaction Scheme 1 or Reaction Scheme 2.

[0057] The compounds of Formula XI and XII are prepared as shown in Reaction Scheme 4. Reduction of the nitro group of the compound of Formula IX (prepared by the sequence shown in Reaction Scheme 1 or 2) with hydrogen gas under pressure in the presence of a palladium catalyst, acid, and in a solvent such as methanol provided the aniline derivative of Formula X. Monomethylation of the compound of Formula X to provide the compound of Formula XI is accomplished by reaction with 1.1 equivalents of a methyl halide or a methyl sulfonate, for example dimethylsulfate, in the presence of a base such as triethylamine and in an inert solvent such as DMF. The monomethylation reaction is typically carried out between 20° C. and 40° C. Preparation of the dimethylaniline of Formula XII is effected by treatment of the aniline of Formula X with an excess of a methyl halide such as methyl iodide or a methyl sulfonate in the presence of a base, for example cesium carbonate, in a solvent such as DMF, with or without heating.

[0058] Reaction Scheme 5 outlines the synthesis of esters of Formula XIII, acids of Formula XIV, and amides of Formula XV. Reaction of a compound of Formula III with a haloalkylcarboxylate ester, for example t-butyl bromoacetate, in the presence of a base such as potassium carbonate and in an inert solvent such as DMF affords the ester of Formula XIII. Deprotection of the ester is effected by methods known to those skilled in the art (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, Wiley Interscience, New York, 1999, pp. 373-442). For example, for t-butyl esters, cleavage to the acid of Formula XIV is accomplished by treatment with trifluoroacetic acid in a solvent such as CH2Cl2. Conversion of the acid to the amide of Formula XV is carried out using common amide coupling procedures well known to those skilled in the art (ref.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976). In a preferred procedure, the acid of Formula XIV is treated with a primary or secondary amine in the presence of 1-hydroxybenzotriazole and 1,3-dicyclohexylcarbodiimide in an aprotic solvent such as CH2Cl2 or DMF.

[0059] The preparation of acids of Formula XVII and amides of Formula XVIII is shown in Reaction Scheme 6. Conversion of an ester of Formula XVI (prepared as shown in Reaction Schemes 1 or 2) to an acid of Formula XVII is accomplished using standard ester cleavage conditions well known to those skilled in the art (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, Wiley Interscience, New York, 1999, pp. 373-442). In the case of a methyl ester of Formula XVI, treatment with aqueous sodium hydroxide in a solvent such a methanol or a methanol/THF mixture at 20° C. to 40° C. provides the acid of Formula XVII. Conversion of the acid of Formula XVII to the amide of Formula XVIII is achieved using common amide coupling procedures well known to those skilled in the art (ref.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976). In a preferred procedure, the acid of Formula XVII is treated with a primary or secondary amine in the presence of 1-hydroxybenzotriazole and a carbodiimide, for example 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide, in a solvent such as DMF or CH2Cl2. A base such a diusopropylethylamine can be added as an acid scavenger.

[0060] The synthesis of piperidine derivatives of Formula XIX, XX, XXI, XXII, and XXIII is described in Reaction Scheme 7. Reaction of a compound o f Formula III with an N-protected piperidine substituted with a 4-haloalkyl or 4-sulfonyloxyalkyl group, such as 4-(toluenesulfonyloxymethyl)-1-(t-butoxycarbonyl)piperidine, in the presence of a base such as cesium carbonate in a solvent such as DMF, with or without heating, provides the carbamate of Formula XIX. Cleavage of the carbamate group in the compound of Formula XIX is carried out under standard conditions well known to those skilled in the art (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, Wiley Interscience, New York, 1999, pp. 503-550) to provide the piperidine of Formula XX. In the case of a (t-butoxycarbonyl)piperidine derivative, the cleavage is effected by treatment with trifluoroacetic acid in CH2Cl2.

[0061] Conversion of the piperidine of Formula XX to an amide of Formula XXI is carried out using amide-coupling procedures well known to those skilled in the art (ref.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976). In a preferred method, the piperidine of Formula XX is treated with an acyl chloride in the presence of an amine such as triethylamine and in an inert solvent such as CH2Cl2 with or without heating. Alternatively, the piperidine of Formula XX may be coupled with an acid in the presence of coupling agents such as hydroxybenzotriazole and a carboduimide to provide an amide of Formula XXI. Preparation of the urea of Formula XXII is achieved by treatment of the amine of Formula XX with an isocyanate and a base such as triethylamine in a solvent such as CH2Cl2 with or without heating. Alkylation of the piperidine of Formula XX provides N-substituted piperidines of Formula XXIII. In a typical procedure, the piperidine is treated with an alkyl halide or an alkyl sulfonate in the presence of a base such as triethylamine and in a solvent such as CH2Cl2.

[0062] Alcohols of Formula XXV and amines of Formula XXVI are synthesized by the sequence shown in Reaction Scheme 8. A protected alcohol of Formula XXIV is prepared by the procedure shown in Reaction Schemes 1 or 2. Deprotection of the alcohol under the appropriate conditions for the chosen protecting group (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, Chapter 2) provides the alcohol of Formula XXV. For example, when the protecting group is a tetrahydropyranyl moiety, the alcohol is liberated by treatment of the compound of Formula XXIV with p-toluenesulfonic acid in a solvent such as methanol. The alcohol of Formula XXV is converted to a leaving group (e.g., a halide or sulfonate) and then treated with a primary or secondary amine to afford an amine of Formula XXVI. For example, the alcohol may be converted to a mesylate derivative by reaction with methanesulfonyl chloride and a base such as triethylamine in CH2Cl2. Subsequent reaction of the mesylate with a primary or secondary amine in the presence of a base such as triethylamine in a solvent such as CH2Cl2 provides the amine of Formula XXVI.

[0063] Amides of Formula XXVIII are prepared from amines of Formula XXVII as shown in Reaction Scheme 9. Amines of Formula XXVII wherein D is a direct bond are prepared as in Reaction Scheme 1 or 4. Amines of Formula XXVII wherein D is other than a direct bond are prepared as in Reaction Scheme 8. Conversion of the amines of Formula XXVII to the amides of Formula XXVIII is carried out using amide-coupling conditions well known to those skilled in the art (ref.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976). For example, reaction of the amine of Formula XXVII with an acid chloride in the presence of a base such as triethylamine in a solvent such as CH2Cl2 provides the amide of Formula XXVIII. Conversion of the amines of Formula XXVII to carbamate derivatives can be carried out using conditions well known to those skilled in the art. (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, P. 503-550). Preparation of sulfonamide derivatives from an amine of Formula XXVII can also be achieved using methods such as that described for the conversion of the intermediate of Formula II to the sulfonamide of Formula III.

[0064] The synthesis of pyridine derivatives of Formula XXX is accomplished as shown in Reaction Scheme 10. The chloropyridine derivative of Formula XXIX is prepared using the chemistry described in Reaction Schemes 1 or 2. Treatment of the compound of Formula XXIX with a primary or secondary amine in a solvent such as THF at temperatures from 20° C. to 100° C., using sealed, pressurized vessel as appropriate, provides the aminopyridine of Formula XXX.

[0065] Amine-substituted phenol ethers of Formula XXXII are prepared from (O-allyl)phenols as indicated in Reaction Scheme 11. The starting allyl ethers of Formula XXXI are prepared as shown in Reaction Schemes 1 or 2. Treatment of the compound of Formula XXXI with osmium tetroxide and trimethylamine N-oxide in a solvent such as acetone followed by treatment with sodium periodate gives an intermediate aldehyde that is typically used without purification. Reaction of the unpurified aldehyde with a primary or secondary amine and a reducing agent such as sodium triacetoxyborohydride in a solvent such as ethanol with or without heating affords the amine of Formula XXXII.

[0066] Conversion of the ester of Formula XXXIII to the tertiary alcohol of Formula XXXIV is carried out as shown in Reaction Scheme 12. Reaction of the ester of Formula XXXIII with an excess of a methyl organometallic reagent such as methyl magnesium bromide in a solvent such as THF at a temperature ranging from 0° C. to 25° C. yields the alcohol of Formula XXXIV.

[0067] Preparation of the 1,3,4-oxadiazole of Formula XXXVI is carried out as shown in Reaction Scheme 13 using methods well known to those skilled in the art (ref: Joule, J. A.; Mills, K.; Smith, G. F. Heterocyclic Chemistry, 3rd ed., Chapman & Hall: London, 1995; 452-456 and references cited therein). For example, the ester of Formula XXXV is treated with hydrazine in methanol with heating up to the reflux point. The resulting acyl hydrazide intermediate is used without purification in a subsequent reaction with an alkyl acetimidate in pyridine with heating at reflux to provide the oxadiazole of Formula XXXVI.

[0068] Synthesis of the 1,2,4-oxadiazole of Formula XXXVII is achieved as shown in Reaction Scheme 14 using methods well known to those skilled in the art (ref: Joule, J. A.; Mills, K.; Smith, G. F. Heterocyclic Chemistry, 3rd ed., Chapman & Hall: London, 1995; 452-456 and references cited therein). For example, treatment of the acid of Formula XVII with hydroxbenzotrlazole, a carbodiimide, and acetamidoxime (N-hydroxy ethanimidamide) in the presence of a base such as triethylamine provides an intermediate that is heated in refluxing pyridine to provide the oxadiazole of Formula XXXVII.

[0069] The 1,2,4-oxadiazole of Formula XXXIX is prepared from the nitrile of Formula XXXVIII (Reaction Scheme 15) using methods well-known to those skilled in the art (ref: Joule, J. A.; Mills, K.; Smith, G. F. Heterocyclic Chemistry, 3rd ed., Chapman & Hall: London, 1995; 452-456 and references cited therein). For example, reaction of the nitrile of Formula XXXVIII with hydroxylamine in a solvent such as ethanol at temperatures up to reflux provides an intermediate N-hydroxyamidine that is subsequently treated with acetyl chloride in the presence of a base such as triethylamine in a solvent such as CH2Cl2 to provide the 1,2,4-oxadiazole of Formula XXXIX.

[0070] Reaction Scheme 16 shows the transformation of the amide of Formula XL to the ketone of Formula XLI. The amide of Formula XL, which is prepared as described in Reaction Scheme 6, is treated with a methyl organometallic reagent such as methyl magnesium bromide in a solvent such as THF to provide the ketone of Formula XLI. The range of the reaction temperature is from −20° C. to 25° C.

[0071] β-Amino amides of Formula XLIII are prepared from acrylamides of Formula XLII as shown in Reaction Scheme 17. For example, an acrylamide of Formula XLII, which is prepared as described in Reaction Scheme 9, is treated with a primary or secondary amine in a solvent such as toluene to provide the β-amino amide of Formula XLIII.

[0072] Preparation of the sulfonamide intermediate of Formula XLIX (a single enantiomer of the compound of Formula III) is outlined in Reaction Scheme 18. Reaction of the α-anion of the intermediate of Formula XLIV (ref: Josien, H.; Martin, A.; Chassaing, G. Tetrahedron Lett. 1991, 32, 6547) with an alkylating agent such as an alkyl halide (e.g., an alkyl chloride, alkyl bromide, or alkyl iodide) or an alkyl sulfonate (e.g., an alkyl mesylate, alkyl tosylate, or alkyl trifluoromethanesulfonate) provides the intermediate of Formula XLV. The α-anion of the compound of Formula XLIV is formed by treatment with a strong base such as an alkyl lithium (e.g., n-BuLi) or a dialkylamide (e.g., lithium diisopropylamide) in a solvent such as THF with or without a co-solvent such as HMPA. The reaction temperature is typically between −78° C. and 25° C. Removal of the benzhydrylidene protecting group of the compound of Formula XLV is carried out under conditions well known to those skilled in the art (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, Wiley Interscience, New York, 1999, pp. 587-588). For example, the compound of Formula XLV is treated with an acid such as HCl in water in a solvent such as THF to effect hydrolysis of the benzhydrylidene protecting group. The resulting amine of Formula XLVI is treated with a sulfonylating agent as described for Reaction Scheme 1 to provide the sulfonamide of Formula XLVII. Hydrolysis of the acylsulfonamide of Formula XLVII to afford the acid of Formula XLVIII is carried out by treatment with hydroxide ion, for example in the form of lithium hydroxide, in the presence of additives such as lithium bromide and tetrabutylammonium bromide. The acid of Formula XLVIII is converted to the amide of formula XLIX under conditions that are well known to those skilled in the art (general ref for amide preparation.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976). For example, reaction of the compound of Formula XLVIII with ammonium chloride in the presence of 1-hydroxybenzotriazole, a carbodiimide reagent, and an amine base such as diusopropylethylamine provides the amide of Formula XLIX. This reaction is typically run in a polar solvent such as DMF and at a reaction temperature from 0° C. to 40° C. The amide of Formula XLIX is converted to the compounds of Formula I by the method described in Reaction Scheme 1.

[0073] Reaction Scheme 19 illustrates one method for synthesis of an α-substituted (N-sulfonamido)acetamide intermediate of Formula III starting with an activated glycine derivative of Formula L. Reaction of the compound of Formula L (ref.: Haufe, G.; Laue, K. W.; Trifler, M. U.; Takeuchi, Y.; Shibata, N. Tetrahedron 1998, 54, p. 5929-5938; Kroger, S.; Haufe, G. Amino Acids 1997, 12, p. 363-372) with an alkylating agent such as an alkyl halide (e.g., an alkyl chloride, alkyl bromide, or alkyl iodide) or an alkyl sulfonate (e.g., an alkyl mesylate, an alkyl tosylate, or an alkyl trifluoromethanesulfonate) in the presence of a base such as potassium carbonate and an additive such as tetrabutylammonium bromide and in an inert solvent such as acetonitrile at a reaction temperature of between 25° C. and 70° C. provides the compound of Formula LI. Removal of the benzhydrylidene protecting group is carried out under conditions well known to those skilled in the art (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, Wiley Interscience, New York, 1999, pp. 587-588). For example, a solution of the compound of Formula LI in a solvent such as diethyl ether is treated with aqueous acid (e.g., aqueous HCl), typically at a reaction temperature of between 0° C. and 30° C., to provide the amine ester of Formula LII. Conversion of the ester of Formula LII to the amide of Formula II is carried out using procedures well known to those skilled in the art. For example, when the compound of Formula LII is an ethyl ester, hydrolysis of the ester is achieved by treatment of an ethereal solution with an acid such as HCl, typically with heating of the reaction mixture in refluxing solvent. The resulting acid intermediate is then converted to a methyl ester of Formula LII by transformation to the acid chloride under standard conditions, (e.g., treatment with thionyl chloride and methanol), followed by reaction with aqueous ammonia in a solvent such as toluene (ref.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976).. The amine of Formula II is converted to the compound of Formula I as described in Reaction Scheme 1.

[0074] Preparation of the compound of Formula LVII is shown in Reaction Scheme 20. Alkene LIII is prepared as described in Reaction Scheme 18 from an intermediate of Formula XLIV and 1-bromo-2-methyl-2-propene). Treatment of the alkene of Formula LIII with HF.pyridine in a solvent such as THF at a reaction temperature between 0° C. and 25° C. affords the fluoroalkyl compound of Formula LIV. Conversion of the compound of Formula LIV to the amide of Formula LV is accomplished as described in Reaction Scheme 18. Transformation of the amide of Formula LV to the compound of Formula LVI is carried out as described in Reaction Scheme I.

[0075] The syntheses of the compounds of Formula LXII and Formula LXIV are outlined in Reaction Scheme 21. Ethyl 2-amino-4-methyl-4-pentenoate (prepared as in Reaction Scheme 19 from (benzhydrylideneamino)acetic acid ethyl ester and 1-bromo-2-methyl-2-propene) is treated with a sulfonylating agent such as a sulfonyl chloride in the presence of a base such as triethylamine in an inert solvent such as CH2Cl2 to afford the ester of Formula LVII. Reaction of the ester of Formula LVII with HF.pyridine in a solvent such as THF and at a reaction temperature of between 0° C. and 25° C. provides a mixture of the fluoroalkyl derivative of Formula LVIII and the lactone of Formula LIX. These products are separated and carried on individually into subsequent reactions.

[0076] The ester of Formula LVIII is hydrolyzed to the acid of Formula LX using methods well known to those skilled in the art (ref.: T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, Wiley Interscience, New York, 1999, pp. 373-442). For example, treatment of the ester of Formula LVIII with aqueous sodium hydroxide in a solvent such as methanol affords the acid of Formula LX. The acid of Formula LX is converted to the amide of Formula LXI using the procedure described in Reaction Scheme 18 for the preparation of the amide of Formula XLIX. Preparation of the amide of Formula LXII from the compound of Formula LXI is achieved as described in Reaction Scheme 1.

[0077] For the lactone of Formula LIX, treatment with aqueous ammonia provides the amide of Formula LXIII. This reaction is typically carried out with heating in a sealed tube. The reaction temperature is between 40° C. and 80° C. Further conversion of the intermediate of Formula LXIII to the sulfonamide of Formula LXIV proceeded as described in Reaction Scheme 1.

[0078] The synthetic sequence for preparation of a difluoroalkyl amide of Formula LXIX is shown in Reaction Scheme 22. The compound of Formula L is treated with 4-bromo-1-butene in the presence of a base such potassium carbonate in the presence of a tetraalkylammonium halide salt such as tetrabutylammonium bromide in a solvent such as CH3CN at a temperature from 20° C. to 70° C. Removal of the benzhydrylidene protecting group as described in Reaction Scheme 19 provides an intermediate amine that is then treated with a sulfonylating reagent such as a sulfonyl chloride to provide the ester of Formula LXV. Alkylation of the sulfonamide nitrogen is accomplished using the procedure described in Reaction Scheme 1 to afford the compound of Formula LXVI. Conversion of the alkene of Formula LXVI to the aldehyde of Formula LXVII is achieved by reaction of the alkene with osmium tetroxide and trimethylamine N-oxide in a solvent such as acetone, followed by treatment with sodium periodate. The reaction temperature is typically 20° C. to 40° C. Reaction of the aldehyde of Formula LXVII with a fluorinating agent such as DAST in a solvent such as CH2Cl2 yields the difluoroalkyl derivative of Formula LXVIII. The compound of Formula LXVIII is converted to the amide of Formula LXIX by hydrolysis of the ester to an acid using an base such as sodium hydroxide in a solvent such as methanol. The intermediate acid was converted to the amide using conditions well known to those skilled in the art (ref.: R. C. Larock “Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 972-976). For example, reaction of the acid with ammonium chloride in the presence of hydroxybenzotriazole and a carboduimide reagent and an amine base such as diusopropylethylamine provided the amide of Formula LXIX. This reaction is typically run in a polar solvent such as DMF and at a reaction temperature from 0° C. to 40° C.

[0079] The α-amino amide of Formula LXXI is prepared using the reaction showed in Reaction Scheme 23. The amide of Formula LXX is prepared as described in Reaction Scheme 9. Treatment of the compound of Formula LXX with a secondary or tertiary amine in a solvent such as THF at a reaction temperature between 20° C. and 40° C. affords the amine of Formula LXXI.

BIOLOGICAL TESTING METHODS

[0117] Compounds of Formula (I) are expected to possess γ-secretase inhibitory activity. The detection of γ-secretase activity requires assays capable of reliable, accurate and expedient detection of γ-secretase cleavage products, particularly Aβ. The γ-secretase inhibitory activity of the compounds of the present invention is demonstrated using assays for such activity, for example, using the assays described below. Compounds within the scope of the present invention have been shown to inhibit the activity of γ-secretase, as determined using assays for such activity.

[0118] Compounds provided by this invention should also be useful as standards and reagents in determining the ability of a potential pharmaceutical to inhibit Aβ production. These would be provided in commercial kits comprising a compound of this invention.

[0119] In Vitro Binding Assay to Identify γ-secretase Inhibitors.

[0120] Competitive binding assays can be used to identify molecules that inhibit the binding of a radiolabeled γ-secretase inhibitor and therefore inhibit γ-secretase activity. For example, [3H]-Compound A can be used for binding assays with membranes from THP-1 cells (Seiffert, D.; Bradley, J. et al., J. Biol. Chem. 2000, 275, 34086-34091). Compound A is (2R,3S) N1-[(3S)-hexahydro-1-(3-phenoxybenzyl)-2-oxo-1H-azepin-3-yl]-2-(2-methylpropyl)-3-(propyl)-butanediamide, the synthesis of which is described in U.S. patent U.S. Pat. No. 6,331,408 (Dec. 18, 2001); PCT Publication WO 00/28331; PCT Publication WO 00/07995; and Seiffert, D., Bradley, J. et al., J. Biol. Chem. 2000, 275. 34086-34091.

[0121] For these assays, THP-1 cells were grown in spinner cultures in RPMI 1640 containing L-glutamine and 10 μM β-mercaptoethanol to a density of 5×105 cells/ml. Cells were harvested by centrifugation and cell pellets were quick frozen in dry ice/ethanol and stored at −70° C. prior to use. The pellets of approximately 2×104 THP-1 cells were homogenized using a Brinkman Polytron at setting 6 for 10 sec. The homogenate was centrifuged at 48,000×g for 12 min, and the resulting pellet was washed by repeating the homogenization and centrifugation. The final cell pellet was resuspended in buffer to yield a protein concentration of approximately 0.5 mg/ml. Assays were initiated by the addition of 150 μl of membrane suspension to 150 μl of assay buffer containing 0.064 μCi of radioligand and various concentrations of unlabeled compounds. Binding assays were performed in duplicate in polypropylene 96-well plates in a final volume of 0.3 ml containing 50 mM Hepes, pH 7.0, and 5% dimethyl sulfoxide. Nonspecific binding was defined using incubations with 300 nM compound A (Seiffert, D., Bradley, J. et al., J. Biol. Chem. 2000, 275, 34086-34091). After incubating at 23° C. for 1.3 hr, bound ligand was separated from free radioligand by filtration over GFF glass fiber filters presoaked in 0.3% ethyleneimine polymer solution. Filters were washed three times with 0.3 ml of ice cold phosphate-buffered saline, pH 7.0, containing 0.1% Triton X-100. Filter-bound radioactivity was measured by scintillation counting. IC50 values were then determined and used to calculate Ki values using the Cheng-Prusoft correction for IC50 values. Compounds were scored as active γ-secretase inhibitors if Ki values were less than 10 μM.

[0122] Examples of the results obtained when the invention compounds are subjected to the above described assay are shown in Table 1. In the table, an inhibitory concentration (IC50) of less than or equal to 50 nM is represented by +++; between 50 nM and 500 nM by ++; between 500 nM and 10000 nM by +.

[0124] An isolated membrane fraction which contains functionally active γ-secretase and β-APP substrates can generate γ-secretase cleavage products including Aβ (Roberts, S. B.; Hendrick, J. P.; Vinitsky, A.; Lewis, M.; Smith, D. W.; Pak, R. PCT Publication WO 01/0175435; Fechteler, K.; Kostka, M.; Fuchs, M. Patent Application No. DE 99-19941039; Shearman, M.; Beher, D. et al., Biochemistry, 2000, 39, 8698-8704; Zhang, L. Song, L. et al., Biochemistry 2001, 40, 5049-5055). An isolated membrane fraction can be prepared from human derived cell lines such as HeLa and H4 which have been transfected with wild type or mutant forms of β-APP or a human alkaline phosphatase β-APP fusion construct, and stably express high levels of γ-secretase substrates. The endogenous γ-secretase present in the isolated membranes prepared at 0-4° C. cleaves the β-APP substrates when the membranes are shifted from 0-4 to 37° C. Detection of the cleavage products including Aβ can be monitored by standard techniques such as immunoprecipitation (Citron, M.; Diehl, T. S. et al., Proc. Natl. Acad. Sci. USA, 1996, 93,13170-13175), western blot (Klafki, H. -W.; Ambramowski, D. et al., J. Biol. Chem.. 1996, 271, 28655-28659), enzyme linked immunosorbent assay (ELISA ) as demonstrated by Seubert, P.; Vigo-Pelfrey, C. et al., Nature, 1992, 359, 325-327, or by a preferred method using time-resolved fluorescence of the homogeneous sample containing membranes and Aβ (Roberts, S. B.; Hendrick, J. P.; Vinitsky, A.; Lewis, M.; Smith, D. W.; Pak, R. PCT Publication WO 01/0175435; Shearman, M.; Beher, D. et al., Biochemistry, 2000, 39, 8698-8704). The Aβ present in a homogeneous sample containing membranes can be detected by time-resolved fluorescence with two antibodies that recognize different epitopes of Aβ. One of the antibodies recognizes an epitope that is present in Aβ but not present in the precursor fragments; preferably the antibody binds the carboxyl terminus of Aβ generated by the γ-secretase cleavage. The second antibody binds to any other epitope present on Aβ. For example, antibodies that bind the N-terminal region (e.g., 26D6-B2-B3® SIBIA Neurosciences, La Jolla, Calif.) or bind the C-terminal end (e.g., 9S3.2® antibody, Biosolutions, Newark, Del.) of the Aβ peptide are known. The antibodies are labeled with a pair of fluorescent adducts that transfer fluorescent energy when the adducts are brought in close proximity as a result of binding to the N- and C-terminal ends or regions of Aβ. A lack of fluorescence is indicative of the absence of cleavage products, resulting from inhibition of γ-secretase. The isolated membrane assay can be used to identify candidate agents that inhibit the activity of γ-secretase cleavage and Aβ production.

[0125] A typical membrane-based assay requires 45 μg membrane protein per well in a 96- or 384-well format. Membranes in a neutral buffer are combined with the test compound and shifted from 0-4 to 37° C. Test agents may typically consist of synthetic compounds, secondary metabolites from bacterial or fungal fermentation extracts, or extracts from plant or marine samples. All synthetic agents are initially screened at doses ranging from 10-100 μM or in the case of extracts at sufficient dilution to minimize cytotoxicity. Incubation of the membranes with the test agent will continue for approximately 90 minutes at which time fluorescence labeled antibodies are added to each well for Aβ quantitation. The time-resolved fluorescence detection and quantitation of Aβ is described elsewhere (Roberts, S. B.; Hendrick, J. P.; Vinitsky, A.; Lewis, M.; Smith, D. W.; Pak, R. PCT Publication WO 01/0175435; Shearman, M.; Beher, D. et al., Biochemistry, 2000. 39, 8698-8704). Results are obtained by analysis of the plate in a fluorescence plate reader and comparison to the mock treated membranes and samples in which known amounts of Aβ were added to construct a standard concentration curve. A positive acting compound is one that inhibits the Aβ relative to the control sample by at least 50% at the initial tested concentration. If a compound is found to be active then a dose response experiment is performed to determine the lowest dose of compound necessary to elicit the inhibition of the production of Aβ. Compounds were scored as active γ-secretase inhibitors if Ki values were less than 10 μM.

[0126] Examples of the results obtained when the invention compounds are subjected to the above described assay are shown in Table 2. In the table, an inhibitory concentration (IC50) of less than or equal to 50 nM is represented by +++; between 50 nM and 500 nM by ++; between 500 nM and 10000 nM by +.

[0127] In Vitro Assays to Identify γ-secretase Inhibitor Based on the Inhibition of Aβ Formation in Cultured Cells.

[0128] Cultured human cell lines, such as HEK293 and H4 cells, which express APP and γ-secretase activity or transfected derivative cell lines that overexpress wild-type APP, mutant APP, or APP fusion proteins will secrete Aβ peptides into the culture media that can be quantified as previously outlined (Dovey, H., John, V. et al., J. Neurochem. 2001, 76, 173-181). The incubation of these cultured cells with γ-secretase inhibitors decreases the production of Aβ peptides. For instance, H4 cells stably transfected to overexpress the HPLAP-APP fusion protein described above were grown as above, detached, and adjusted to 2×105 cells/ml. 100 μl of the resulting suspension was then added to each well of a 96-well plate. After 4 hrs, the media was removed and replaced with 100 μl serum-free media containing various dilutions of the test compound. Plates were then incubated for 18 hrs at 37° C. and a 100 μl aliquot of the tissue culture supernatant was removed for determination of Aβ levels using time-resolved fluorescence of the homogenous sample as outlined above. Alternately, the other methods described above for Aβ determination could be used. The extent of Aβ inhibition was used to calculate the IC50 value for the test compound. Compounds of the present invention are considered active when tested in the above assay if the IC50 value for the test compound is less than 50 μM.

[0129] Examples of the results obtained when the invention compounds are subjected to the above described assay are shown in Table 3. In the table, an inhibitory concentration (IC50) of less than or equal to 50 nM is represented by +++; between 50 nM and 500 nM by ++; between 500 nM and 50000 nM by +.

[0130] Compounds of the present invention have been demonstrated to have an IC50 value less than 10 μM in one or all of the above assays. Therefore, the compounds of Formula I or pharmaceutical compositions thereof are useful in the treatment, alleviation or elimination of disorders or other disorders associated with the inhibition of β-amyloid peptide.

[0131] In addition to cleaving APP, γ-secretase cleaves other substrates, including: the Notch family of transmembrane receptors (reviewed in: Selkoe, D. Physiol. Rev. 2001, 81, 741-766; Wolfe, M. J. Med. Chem. 2001 44, 2039-2060); LDL receptor-related protein (May, P., Reddy, Y. K., Herz, J. J. Biol. Chem. 2002, 277, 18736-18743); ErbB-4 (Ni, C. Y., Murphy, M. P., Golde, T. E., Carpenter, G. Science 2001, 294, 2179-2181); E-cadherin (Marambaud, P., Shioi, J., et al., EMBO J. 2002, 21,1948-1956); and CD44 (Okamoto, I., Kawano, Y., et al., J. Cell Biol. 2001, 155, 755-762). If inhibition of cleavage of non-APP substrates causes undesirable effects in humans, then desired γ-secretase inhibitors would preferentially inhibit APP cleavage relative to unwanted substrates. Notch cleavage can be monitored directly by measuring the amount of cleavage product or indirectly by measuring the effect of the cleavage product on transcription (Mizutani, T., Taniguchi, Y., et al. Proc. Natl. Acad. Sci. USA 2001, 98, 9026-9031).

[0132] In Vivo Assays for the Determination of Aβ Reduction by γ-secretase Inhibitors.

[0133] In vivo assays are available to demonstrate the inhibition of γ-secretase activity. In these assays, animals, such as mice, that express normal levels of APP and γ-secretase or are engineered to express higher levels of APP and hence Aβ can be used to demonstrate the utility of γ-secretase inhibitors (Dovey, H., John, V., et al., J. Neurochem. 2001, 76, 173-181). In these assays, γ-secretase inhibitors were administered to animals and Aβ levels in multiple compartments, such as plasma, cerebral spinal fluid, and brain extracts, were monitored for Aβ levels using methods previously outlined. For instance, Tg2576 mice, which overexpress human APP, was administered γ-secretase inhibitors by oral gavage at doses that will cause measurable Aβ lowering, typically less than 100 mg/kg. Three hours after dosing plasma, brain, and CSF were collected, frozen in liquid nitrogen, and stored at −80° C. until analysis. For Aβ detection, plasma was diluted 15-fold in PBS with 0.1% Chaps while CSF was diluted 15-fold in 1% Chaps with protease inhibitors (5 μg/ml leupeptin, 30 μg/ml aprotinin, 1 mM phenylmethylsulfonylfluoride, 1 μM pepstatin). Brains were homogenized in 1% Chaps with protease inhibitors using 24 ml solution/g brain tissue. Homogenates were then centrifuged at 100,000×g for 1 hr at 4° C. The resulting supernatants were then diluted 10-fold in 1% Chaps with protease inhibitors. Aβ levels in the plasma, CSF, and brain lysate were measured using time-resolved fluorescence of the homogenous sample or one of the other methods previously described.

[0134] A γ-secretase inhibitor is considered active in one of the above in vivo assays if it reduces Aβ by at least 50% at a dosage of 100 mg/kg.

[0135] Therefore, the compounds of Formula I or pharmaceutical compositions thereof are useful in the treatment, alleviation or elimination of disorders or other disorders associated with the inhibition of β-amyloid peptide.

[0136] In another embodiment, this invention includes pharmaceutical compositions comprising at least one compound of Formula I in combination with a pharmaceutical adjuvant, carrier or diluent.

[0137] In still another embodiment, this invention relates to a method of treatment or prevention of disorders responsive to the inhibition of β-amyloid peptide in a mammal in need thereof, which comprises administering to said mammal a therapeutically effective amount of a compound of Formula I or a nontoxic pharmaceutically acceptable salt, solvate or hydrate thereof.

[0138] In yet another embodiment, this invention relates to a method for treating Alzheimer's Disease and Down's Syndrome in a mammal in need thereof, which comprises administering to said mammal a therapeutically effective amount of a compound of Formula I or a non-toxic pharmaceutically acceptable salt, solvate or hydrate thereof.

[0139] For therapeutic use, the pharmacologically active compounds of Formula I will normally be administered as a pharmaceutical composition comprising as the (or an) essential active ingredient at least one such compound in association with a solid or liquid pharmaceutically acceptable carrier and, optionally, with pharmaceutically acceptable adjuvants and excipients employing standard and conventional techniques.

[0140] The pharmaceutical compositions include suitable dosage forms for oral, parenteral (including subcutaneous, intramuscular, intradermal and intravenous) bronchial or nasal administration. Thus, if a solid carrier is used, the preparation may be tableted, placed in a hard gelatin capsule in powder or pellet form, or in the form of a troche or lozenge. The solid carrier may contain conventional excipients such as binding agents, fillers, tableting lubricants, disintegrants, wetting agents and the like. The tablet may, if desired, be film coated by conventional techniques. If a liquid carrier is employed, the preparation may be in the form of a syrup, emulsion, soft gelatin capsule, sterile vehicle for injection, an aqueous or non-aqueous liquid suspension, or may be a dry product for reconstitution with water or other suitable vehicle before use. Liquid preparations may contain conventional additives such as suspending agents, emulsifying agents, wetting agents, non-aqueous vehicle (including edible oils), preservatives, as well as flavoring and/or coloring agents. For parenteral administration, a vehicle normally will comprise sterile water, at least in large part, although saline solutions, glucose solutions and like may be utilized. Injectable suspensions also may be used, in which case conventional suspending agents may be employed. Conventional preservatives, buffering agents and the like also may be added to the parenteral dosage forms. The pharmaceutical compositions are prepared by conventional techniques appropriate to the desired preparation containing appropriate amounts of the active ingredient, that is, the compound of Formula I according to the invention. See, for example, Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pa., 17th edition, 1985.

[0141] The dosage of the compounds of Formula I to achieve a therapeutic effect will depend not only on such factors as the age, weight and sex of the patient and mode of administration, but also on the degree of β-AP inhibition desired and the potency of the particular compound being utilized for the particular disorder of disease concerned. It is also contemplated that the treatment and dosage of the particular compound may be administered in unit dosage form and that the unit dosage form would be adjusted accordingly by one skilled in the art to reflect the relative level of activity. The decision as to the particular dosage to be employed (and the number of times to be administered per day) is within the discretion of the physician, and may be varied by titration of the dosage to the particular circumstances of this invention to produce the desired therapeutic effect.

[0142] A suitable dose of a compound of Formula I or pharmaceutical composition thereof for a mammal, including man, suffering from, or likely to suffer from any condition related to β-AP production as described herein, generally the daily dose will be from about 0.05 mg/kg to about 10 mg/kg and preferably, about 0.1 to 2 mg/kg when administered parenterally. For oral administration, the dose may be in the range from about 1 to about 75 mg/kg and preferably from 0.1 to 10 mg/kg body weight. The active ingredient will preferably be administered in equal doses from one to four times a day. However, usually a small dosage is administered, and the dosage is gradually increased until the optimal dosage for the host under treatment is determined. In accordance with good clinical practice, it is preferred to administer the instant compounds at a concentration level that will produce an effective anti-amyloid effect without causing any harmful or untoward side effects. However, it will be understood that the amount of the compound actually administered will be determined by a physician, in the light of the relevant circumstances including the condition to be treated, the choice of compound of be administered, the chosen route of administration, the age, weight, and response of the individual patient, and the severity of the patient's symptoms.

[0143] The following examples are given by way of illustration and are not to be construed as limiting the invention in any way inasmuch as many variations of the invention are possible within the spirit of the invention.
