FIELD OF THE INVENTION

The present invention relates generally to the field of ligands for nicotinic acetylcholine receptors (nAChIZ), activation of nAChRs, and the treatment of disease conditions associated with defective or malfunctioning nicotinic acetylcholine receptors, especially of the brain. Further, this invention relates to novel compounds, which act as ligands for the a7 nAChR subtype, methods of preparing such compounds, compositions comprising such compounds, and methods of use thereof.

BACKGROUND OF THE INVENTION

There are two types of receptors for the neurotransmitter, acetylcholine:
musearinic receptors and nicotinic receptors, based on the selectivity of action of muscarine and nicotine, respectively. Muscarinic receptors are G-protein coupled receptors.
Nicotinic SUBSTITUTE SHEET (RULE 26) receptors are members of the ligand-gated ion channel family. When activated, the conductance of ions across the nicotinic ion channels increases.

Nicotinic alpha-7 receptor protein forms a homo-pentameric channel in vitro that is highly permeable to a variety of cations (e.g., Ca+'). Each nicotinic alpha-7 receptor has four transmembrane domains, named Ml, M2, M3, and M4. The M2 domain has been suggested to form the wall lining the channel. Sequence alignment shows that nicotinic alpha-7 is highly conserved during evolution. The M2 domain that lines the channel is identical in protein sequence from chicken to human. For discussions of the alpha-7 receptor, see, e.g., Revah et al. (1991), Nature, 353, 846-849; Galzi et al.
(1992), Nature 359, 500-505; Fucile et al. (2000), PNAS 97(7), 3643-3648; Briggs et al.
(1999), Eur. J.
Pharmacol. 366 (2-3), 301-308; and Gopalakrishnan et al. (1995), Eur. J.
Pharmacol.
290(3), 237-246.

The nicotinic alpha-7 receptor channel is expressed in various brain regions and is believed to be involved in many important biological processes in the central nervous system (CNS), including learning and memory. Nicotinic alpha-7 receptors are localized on both presynaptic and postsynaptic terminals and have been suggested to be involved in modulating synaptic transmission. It is therefore of interest to develop novel compounds, which act as ligands for the a7nACh receptor subtype, for the treatment of disease conditions associated with defective or malfunctioning nicotinic acetylcholine receptors.

SUMMARY OF THE INVENTION

This invention relates to novel compounds, which act as ligands for the a7 nACh receptor subtype, methods of preparing such compounds, compositions comprising such compounds, and methods of use thereof.

The compounds of the present invention may be prepared conventionally. Some of the known processes that can be used are described below. All starting materials are known or can be conventionally prepared from known starting materials by one of ordinary skill.

Acids that were used in the preparation of the bicyclobase amides were commercially available or were prepared by known procedures described in the literature or as described below. For= example, indazole-3-carboxylic acid was commercially available. A variety of the simple substituted indazole-3-acids, such as the bromoindazole acids, were prepared from the corresponding isatins by basic hydrolysis, diazotization, and reduction (Snyder, H.R. et al., J. Am. Chem. Soc. 1952, 74, 2009).

Several substituted indazole-3-acids were prepared by modifying existing indazole acids or esters. For example, N(1)- and N(2)-protected indazole acids were prepared from the ester through reaction with methoxyethoxymethyl chloride (MEM-Cl) or trimethylsilylethoxymethyl chloride (SEM-Cl) and either sodium hydride or di-isopropylethylamine. N(1)-Alkylated indazole-3-carboxylic acids were prepared from the corresponding indazole esters by standard alkylation or Mitsunobu procedures. N(1)-Arylated indazole-3-carboxylic acids were prepared from the corresponding indazole esters by copper mediated cross couplings with boronic acids. Non-aromatic heterocyclic derivatives were prepared from the corresponding bromides by metal-halogen exchange, trapping of indazole aryllithiums with ketones, followed by reduction or acid mediated elimination. Aromatic substituted indazole-3-acids were prepared from the corresponding bromides via palladium mediated cross-coupling with boronic acids or aryl zinc reagents (Reeder, M.R.; et. al. Org. Proc. Res. Devel. 2003, 7, 696).
Amino indazole acids were prepared using a palladium mediated cross-coupling reaction with secondary amines. Phenol derivatives were prepared from the corresponding methoxy acids using boron tribromide. 6-Amino- and 6-phenyl-7-azaindazole-3-carboxylic acids were prepared from the commercially available 6-fluoro material by reaction with a secondary amine or by nickel mediated cross-coupling with aryl Grignard reagents.
Several substituted indazole-3-acids were prepared from benzene derivatives.
For example, 5-difluoromethoxyindazole-3-acid was prepared from 3-bromo-4-nitrophenol by reaction with ethyl difluoroacetate, reaction with diethyl malonate, decarboxylative saponification, esterification, reduction of the nitro group, and diazotization. 6-Difluoromethoxyindazole-3-acid was prepared in a similar manner from 2-bromo-5-difluoromethoxynitrobenzene. The 2-bromo-5-difluoromethoxynitrobenzene was prepared from 4-nitrophenol by ether formation, nitro reduction with concomitant protection as the amide, nitration, amide hydrolysis, and a Sandmeyer reaction with copper (I) bromide. 6-Benzyloxyindazole-3-carboxylic acid and ester were prepared from 4-methoxynitrobenzene by nitro reduction with concomitant protection as the amide, nitration, amide hydrolysis, Sandmeyer reaction with copper (I) bromide, and demethylation. The phenol was alkylated with benzyl bromide and the arylbromide was subjected to reaction with diethyl malonate, decarboxylative saponification, esterification, reduction of the nitro group, and diazotization. The 5-benzyloxy analog was prepared in a similar manner from 4-benzyloxy-2-bromonitrobenzene (Parker, K.A.;
Mindt, T.L. Org. Lett. 2002, 4, 4265.) The benzyl group was removed by hydrogenolysis and the resulting phenol was transformed to ether derivatives via either alkylation or Mitsunobu reaction conditions. 4-Methoxyindazole acid was prepared from 4-methoxyaniline by amide formation, nitration, amide hydrolysis, Sandmeyer reaction with copper (I) bromide, nitro reduction, isatin formation and rearrangement to the indazole, followed by hydrogenolytic removal of the bromine. 5-Azaindazole-3 -acid was prepared from 4-chloropyridine by metallation and trapping with diethyloxalate, cyclization with hydrazine, and saponification. 6-Azaindazole-3-acid was prepared from 4-chloro-3-nitropyridine by reaction with a malonate anion, decarboxylation, nitro reduction, diazotization, and saponification.

The benziosoxazole esters were prepared from simple benzene derivatives using similar techniques. For example, ethyl 6-bromobenzisoxazole-3-carboxylate was prepared from 2-nitro-1,4-dibromobenzene by reaction with dimethylmalonate, a saponification/decarboxylation sequence, esterification, and reaction with isoamyl nitrite under basic conditions. The 6-methoxybenzisoxazole ester compound was prepared, analogously, from 2,4-dinitrochlorobenzene. Reduction of the resultant 6-nitro group followed by diazotization and oxidation provided the 6-hydroxy compound. The ether was obtained by simple alkylation.

The benzisothiazole carboxylic acids were also prepared using similar strategies outlined for the indazole acids. For example, 6-methoxybenzisothiazole-3-carboxylic acid was prepared from 3-methoxythiophenol by reaction with oxalyl chloride and aluminum chloride followed by treatment with hydroxylamine, hydrogen peroxide, and sodium hydroxide. Amino substituted benzisothiazole acids were prepared from the requisite bromide by a palladium mediated cross-coupling reaction with secondary amines or benzophenone imine. The primary and secondary amines generated this way serve as intermediates for other ligands. For example, the amines were transformed into tertiary amines and amides using standard reductive amination and acylation reactions practiced by those of ordinary skill in the art. 7-Azabenzisothiazole-3-carboxylic acid was prepared from 2-chloronicotinoyl chloride by reaction with the diethylmalonate anion and decarboxylation followed by reaction of the ketone with sulfer, ammonium hydroxide, and ammonia to generate the 7-aza-3-methylbenzisothiazole core. The acid was installed using a benzylic oxidation with N-bromosuccinamide and hydrolysis, followed by basic permanganate oxidation of the alcohol. 7-Aza-6-chlorobenzisothiazole-3-acid was synthesized from the 7-aza-3-methylbenzisothiazole core by oxidation of the pyridine ring nitrogen followed by a rearrangement reaction mediated by triphosgene to install a chlorine atom at the 6-position. The synthesis was completed by a benzylic oxidation in a similar manner to the unsubstituted azabenzisothiazole acid.
The bicycloamines, 3-aminoquinuclidine and the R- and S enantiomers thereof, used in the preparation of the bicyclobase amides were commercially available.
The N-alkylated quinuclidines were prepared by acylation of 3-aminoquinuclidine followed by reduction of the amide.

The bicyclobase amides were prepared from the acids and the bicycloamines using standard peptide coupling agents, such as O-(benzotriazol-1-yl)-N,N,N,N'-tetramethyluronium hexafluorophosphate (HBTU), O-(7-azabenzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate (HATU), O-(benzotriazol-l-yl)-N,N,N;N'-tetramethyluronium tetrafluoroborate (TBTU), hydroxybenztriazole (HOBt) and N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide (EDCI), carbonyl diimidazole (CDI), and 2-chloro-1,3,-dimethylimidazolinium hexafluorophosphate (CIP), or by converting the acids to the corresponding acid chloride followed by reaction with the bicycloamine (Macor, J.E.; Gurley, D.; Lanthorn, T.; Loch, J.; Mack, R.A.;
Mullen, G.;
Tran, 0.; Wright, N.; and J. E. Macor et al., "The 5-HT3-Antagonist Tropisetron (ICS
205-930) was a Potent and Selective a-7 Nicotinic Receptor Partial Agonist,"
Bioorg.
Med. Chem. Lett. 2001, 9, 319-321). The couplings were generally performed at room temperature for 18-24 hours. The resultant adducts were isolated and purified by standard techniques practiced by those of ordinary skill in the art, such as chromatography or recrystallization.

The nicotinic ligands can, alternatively, be prepared by modification of other nicotinic ligands. For example, the cyclic urea ligand was prepared from the corresponding bromide ligand by a palladium-catalyzed cross-coupling reaction.
Amino-substituted ligands were prepared by similar palladium mediated coupling reactions with secondary amines or benzophenone imine. The primary and secondary amines generated this way serve as intermediates for other ligands, as understood by those of ordinary skill in the art. 5-Alkoxybenzisothiazole ligands were prepared by palladium mediated cross coupling with pinacolborane dimer followed by oxidation and alkylation. In some cases, the indazole quinuclidine carboxamides were derivatized at the indazole nitrogen under Mitsunobu conditions or through the copper mediated coupling with boronic acids.
Quaternary quinuclidine salts were prepared by the reaction of the final product with alkylating agents. N-Oxides were prepared by the reaction of the final product with oxidants.

One of ordinary skill in the art will recognize that compounds of Formulas I-IV
can exist in different tautomeric and geometrical isomeric forms. All of these compounds, including cis isomers, trans isomers, diastereomic mixtures, racemates, nonracemic mixtures of enantiomers, substantially pure, and pure enantiomers, are within the scope of the present invention. Substantially pure enantiomers contain no more than 5% w/w of the corresponding opposite enantiomer, preferably no more than 2%, most preferably no more than 1%.

The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example, by the formation of diastereoisomeric salts using an optically active acid or base or formation of covalent diastereomers.
Examples of appropriate acids are tartaric, diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric and camphorsulfonic acid. Mixtures of diastereoisomers can be separated into their individual diastereomers on the basis of their physical and/or chemical differences by methods known to those skilled in the art, for example, by chromatography or fractional crystallization. The optically active bases or acids are then liberated from the separated diastereomeric salts. A different process for separation of optical isomers involves the use of chiral chromatography (e.g., chiral HPLC
columns), with or without conventional derivation, optimally chosen to maximize the separation of the enantiomers. Suitable chiral HPLC columns are manufactured by Diacel, e.g., Chiracel OD and Chiracel OJ among many others, all routinely selectable.
Enzymatic separations, with or without derivitization, are also useful. The optically active compounds of Formulas I-IV can likewise be obtained by utilizing optically active starting materials in chiral synthesis processes under reaction conditions which do not cause racemization.

In addition, one of ordinary skill in the art will recognize that the compounds can be used in different enriched isotopic forms, e.g., enriched in the content of 2H, 3H, "C, 13 C and/or 14C. In one particular embodiment, the compounds are deuterated.
Such deuterated forms can be made by the procedures described in U.S. Patent Nos.
5,846,514 and 6,334,997. As described in U.S. Patent Nos. 5,846,514 and 6,334,997, deuteration can improve the efficacy and increase the duration of action of drugs.

Deuterium substituted compounds can be synthesized using various methods such as described in: Dean, Dennis C.; Editor. Recent Advances in the Synthesis and Applications of Radiolabeled Compounds for Drug Discovery and Development.

Where applicable, the present invention also relates to useful forms of the compounds as disclosed herein, including free base forms and pharmaceutically acceptable salts or prodrugs of all the compounds of the present invention for which salts or prodrugs can be prepared. Pharmaceutically acceptable salts include those obtained by reacting the main compound, functioning as a base, with an inorganic or organic acid to form a salt, for example, salts of hydrochloric acid, sulfuric acid, phosphoric acid, methane sulfonic acid, camphor sulfonic acid, oxalic acid, maleic acid, succinic acid, citric acid, formic acid, hydrobromic acid, benzoic acid, tartaric acid, fumaric acid, salicylic acid, mandelic acid, and carbonic acid. Pharmaceutically acceptable salts also include those in which the main compound functions as an acid and is reacted with an appropriate base to form, e.g., sodium, potassium, calcium, magnesium, ammonium, and choline salts. Those skilled in the art will further recognize that acid addition salts of the claimed compounds may be prepared by reaction of the compounds with the appropriate inorganic or organic acid via any of a number of known methods. Alternatively, alkali and alkaline earth metal salts can be prepared by reacting the compounds of the invention with the appropriate base via a variety of known methods.

The following are further examples of acid salts that can be obtained by reaction with inorganic or organic acids: acetates, adipates, alginates, citrates, aspartates, benzoates, benzenesulfonates, bisulfates, butyrates, camphorates, digluconates, cyclopentanepropionates, dodecylsulfates, ethanesulfonates, glucoheptanoates, glycerophosphates, hemisulfates, heptanoates, hexanoates, fumarates, hydrobromides, hydroiodides, 2-hydroxy-ethanesulfonates, lactates, maleates, methanesulfonates, nicotinates, 2-naphthalenesulfonates, oxalates, palmoates, pectinates, persulfates, 3-phenylpropionates, picrates, pivalates, propionates, succinates, tartrates, thiocyanates, tosylates, mesylates and undecanoates.

For example, the pharmaceutically acceptable salt can be a hydrochloride, a hydrobromide, a hydroformate, or a maleate.

The salts of the present invention also include quaternary ammonium salts obtained by reacting the main compound, functioning as a nucleophile, with agents bearing nucleofugal groups. Examples of those agents include, but are not limited to, methyl iodide, methyl bromide, methyl chloride, methyl triflate, methyl tosylate, methyl mesylate, ethyl iodide, ethyl bromide, ethyl chloride, ethyl triflate, ethyl tosylate, ethyl mesylate, propyl iodide, propyl bromide, propyl chloride, cyclopropylmethyl bromide, benzyl bromide, methylene chloride, and dichloroethane. One skilled in the art will recognize that the list of example agents presented is non-exhaustive and can be expanded within reason.

For example, the quaternary ammonium salt can be formed at the N atom of the azabicyclo structute as shown in the following formula:

~
-N A--r wherein Z is, for example, methyl, chloromethyi, ethyl, chloroethyl, propyl, cyclopropylmethyl, or benzyl, and the corresponding anion A is, for example, iodide, bromide, chloride, triflate, tosylate, or mesylate. See, for example, compounds 1, 13, and 165.

Preferably, the salts formed are pharmaceutically acceptable for administration to mammals. However, pharmaceutically unacceptable salts of the compounds are suitable as intermediates, for example, for isolating the compound as a salt and then converting the salt back to the free base compound by treatment with an alkaline reagent.
For example, alkyl halide addition salts (e.g., salts formed by reaction with methyl iodide) may be envisaged. The free base can then, if desired, be converted to a pharmaceutically acceptable acid addition salt.

One of ordinary skill in the art will also recognize that some of the compounds of Formulas I, II, III, and IV can exist in different polymorphic forms. As known in the art, polymorphism is an ability of a compound to crystallize as more than one distinct crystalline or "polymorphic" species. A polymorph is a solid crystalline phase of a compound with at least two different arrangements or polymorphic forms of that compound molecule in the solid state. Polymorphic forms of any given compound are defined by the same chemical formula or composition and are as distinct in chemical structure as crystalline structures of two different chemical compounds.

One of ordinary skill in the art will further recognize that compounds of Formulas I, II, III, and IV can exist in different solvate forms. Solvates of the compounds of the invention may also form when solvent molecules are incorporated into the crystalline lattice structure of the compound molecule during the crystallization process.

The compounds of the invention can be administered alone or as an active ingredient of a formulation. Thus, the present invention also includes pharmaceutical compositions of compounds of Formulas I-IV, containing, for example, one or more pharmaceutically acceptable carriers.

Numerous standard references are available that describe procedures for preparing various formulations suitable for administering the compounds according to the invention. Examples of potential formulations and preparations are contained, for example, in the Handbook of Pharmaceutical Excipients, American Pharmaceutical Association (current edition); Pharmaceutical Dosage Forms: Tablets (Lieberman, Lachman and Schwartz, editors) current edition, published by Marcel Dekker, Inc., as well as Remington's Pharmaceutical Sciences (Arthur Osol, editor), 1553-1593 (current edition).

In view of their alpha-7 stimulating activity and, preferably their high degree of selectivity, the compounds of the present invention can be administered to anyone needing stimulation of alpha-7 receptors. Administration may be accomplished according to patient needs, for example, orally, nasally, parenterally (subcutaneously, intraveneously, intramuscularly, intrasternally and by infusion) by inhalation, rectally, vaginally, topically and by ocular administration.

Various solid oral dosage forms can be used for administering compounds of the invention including such solid forms as tablets, gelcaps, capsules, caplets, granules, lozenges and bulk powders. The compounds of the present inveption can be administered alone or combined with various pharmaceutically acceptable carriers, diluents (such as sucrose, mannitol, lactose, starches) and excipients known in the art, including but not limited to suspending agents, solubilizers, buffering agents, binders, disintegrants, preservatives, colorants, flavorants, lubricants and the like. Time release capsules, tablets and gels are also advantageous in administering the compounds of the present invention.

Various liquid oral dosage forms can also be used for administering compounds of the inventions, including aqueous and non-aqueous solutions, emulsions, suspensions, syrups, and elixirs. Such dosage forms can also contain suitable inert diluents known in the art such as water and suitable excipients known in the art such as preservatives, wetting agents, sweeteners, flavorants, as well as agents for emulsifying and/or suspending the compounds of the invention. The compounds of the present invention may be injected, for example, intravenously, in the form of an isotonic sterile solution.
Other preparations are also possible.

Suppositories for rectal administration of the compounds of the present invention can be prepared by mixing the compound with a suitable excipient such as cocoa butter, salicylates and polyethylene glycols. Formulations for vaginal administration can be in the form of a pessary, tampon, cream, gel, paste, foam, or spray formula containing, in addition to the active ingredient, such suitable carriers as are known in the art.

For topical administration the pharmaceutical composition can be in the form of creams, ointments, liniments, lotions, emulsions, suspensions, gels, solutions, pastes, powders, sprays, and drops suitable for administration to the skin, eye, ear or nose.
Topical administration may also involve transdermal administration via means such as transdermal patches.

Aerosol formulations suitable for administering via inhalation also can be made.
For example, for treatment of disorders of the respiratory tract, the compounds according to the invention can be administered by inhalation in the form of a powder (e.g., micronized) or in the form of atomized solutions or suspensions. The aerosol formulation can be placed into a pressurized acceptable propellant.

The compounds can be administered as the sole active agent or in combination with other pharmaceutical agents such as other agents used in the treatment of cognitive impairment and/or memory loss, e.g., other a-7 agonists, PDE4 inhibitors, calcium channel blockers, muscarinic ml and m2 modulators, adenosine receptor modulators, ampakines, NMDA-R modulators, mGluR modulators, dopamine modulators, serotonin modulators, canabinoid modulators, and cholinesterase inhibitors (e.g., donepezil, rivastigimine, and glanthanamine). In such combinations, each active ingredient can be administered either in accordance with their usual dosage range or a dose below their usual dosage range.

The compounds of the invention can be used in conjunction with "positive modulators" which enhance the efficacy of nicotinic receptor agonists. See, e.g., the positive modulators disclosed in WO 99/56745, WO 01/32619, and WO 01/32622.
Such combinational therapy can be used in treating conditions/diseases associated with reduced nicotinic transmission.

Further the compounds may be used in conjunction with compounds that bind to A(3 peptides and thereby inhibit the binding of the peptides to a7nACh receptor subtypes.
See, e.g., WO 99/62505.

The present invention further includes methods of treatment that involve activation of a-7 nicotinic receptors. Thus, the present invention includes methods of selectively activating/stimulating a-7 nicotinic receptors in a patient (e.g., a mammal such as a human) wherein such activation/stimulation has a therapeutic effect, such as where such activation may relieve conditions involving neurological syndromes, such as the loss of memory, especially long-term memory. Such methods comprise administering to a patient (e.g., a mammal such as a human), an effective amount of a compound of Formulas I-IV, alone or as part of a formulation, as disclosed herein.

In accordance with a method aspect of the invention, there is provided a method of treating a patient (e.g., a mammal such as a human) suffering from a disease state (e.g., memory impairment) comprising administering to the patient a compound according to Formulas I-IV. Preferably, the disease state involves decreased nicotinic acetylcholine receptor activity.

In accordance with another method aspect of the invention there is provided a method for alleviating inhibition of cholinergic function induced by AP
peptides in a patient (e.g., a mammal such as a human) comprising administering an effective amount of a compound according to Formulas I-IV.

A subject or patient in whom administration of the therapeutic compound is an effective therapeutic regimen for a disease or disorder is preferably a human, but can be any animal, including a laboratory animal in the context of a clinical trial or screening or activity experiment. Thus, as can be readily appreciated by one of ordinary skill in the art, the methods, compounds and compositions of the present invention are particularly suited to administration to any animal, particularly a mammal, and including, but by no means limited to, humans, domestic animals, such as feline or canine subjects, farm animals, such as but not limited to bovine, equine, caprine, ovine, and porcine subjects, wild animals (whether in the wild or in a zoological garden), research animals, such as mice, rats, rabbits, goats, sheep, pigs, dogs, cats, etc., avian species, such as chickens, turkeys, songbirds, etc., i.e., for veterinary medical use.

The compounds of the present invention are nicotinic alpha-7 ligands, preferably agonists, especially partial agonists, for the alpha-7 nicotinic acetylcholine receptor.
Assays for determining nicotinic acetylcholine activity are known within the art. See, e.g., Davies, A.R., et al., Characterisation of the binding of [3H]methyllycaconitine= a new radioligand for labelling alpha 7-type neuronal nicotinic acetylcholine receptors.
Neuropharmacology, 1999. 38(5): p. 679-90. As agonists for a7nACh receptors, the compounds are useful in the prophylaxis and treatment of a variety of diseases and conditions associated with the central nervous system. Nicotinic acetylcholine receptors are ligand-gastrol ion-channel receptors that are composed of five subunit proteins which form a central ion-conducting pore. Presently, there are eleven known neuronal nACh receptor subunits (a2 - 0 and (32 -(34). There are also five further subunits expressed in the peripheral nervous system (al, (31, ,y, S, s).

The nACh receptor subtypes can be homopentameric or heteropentameric. The subtype which has received considerable attention is the homopentameric a7 receptor subtype formed from five 0 subunits. The a7nACh receptors exhibit a high affinity for nicotine (agonist) and for a-bungarotoxin (antagonist). Studies have shown the a7nACh receptor agonists can be useful in the treatment of psychotic diseases, neurodegenerative diseases, and cognitive impairments, among other things. While nicotine is a known agonist, there is a need for the development of other a7nACh receptor agonists, especially selective agonists, which are less toxic or exhibit fewer side effects than nicotine.

The compound anabaseine, i.e., 2-(3-pyridyl)-3,4,5,6-tetrahydropyridine is a naturally occurring toxin in certain marine worms (nemertine worms) and ants.
See, e.g., Kem et al., Toxicon, 9:23, 1971. Anabaseine is a potent activator of mammalian nicotinic receptors. See, e.g., Kem, Amer. Zoologist, 25, 99, 1985. Certain anabaseine analogs such as anabasine and DMAB (3-[4-(dimethylamino)benzylidene]-3,4,5,6-tetrahydro-2',3'-bipyridine) are also known nicotinic receptor agonists. See, e.g., US

5,602,257 and WO 92/15306. One particular anabaseine analog, (E-3-[2,4-dimethoxy-benzylidene]-anabaseine, also known as GTS-21 and DMXB (see, e.g., US
5,741,802), is a selective partial a7nACh receptor agonist that has been studied extensively. For example, abnormal sensory inhibition is a sensory processing deficit in schizophrenics and GTS-21 has been found to increase sensory inhibition through interaction with a7nACh receptors. See, e.g., Stevens et al., Psychopharmacology, 136: 320-27 (1998).
Another compound which is known to be a selective a7nACh receptor agonist is Tropisetron, i.e., laH, 5aH-tropan-3a-yl indole-3-carboxylate. See J. E. Macor et al., The 5-HT3-Antagonist Tropisetron (ICS 205-930) is a Potent and Selective A7 Nicotinic Receptor Partial A og nist. Bioorg. Med. Chem. Lett. 2001, 319-321).

Thus, in accordance with the invention, there is provided a method of treating a patient, especially a human, suffering from age-related dementia and other dementias and conditions with memory loss comprising administering to the patient an effective amount of a compound according to Formulas I-IV.

Thus, in accordance with a further embodiment, the present invention includes methods of treating patients suffering from memory impairment due to, for example, Alzheimer's disease, mild cognitive impairment due to aging, schizophrenia, Parkinson's disease, Huntington's disease, Pick's disease, Creutzfeldt-Jakob disease, depression, aging, head trauma, stroke, CNS hypoxia, cerebral senility, multiinfarct dementia and other neurological conditions, as well as HIV and cardiovascular diseases, comprising administering an effective amount of a compound according to Formulas I-IV.

Amyloid precursor protein (APP) and A(3 peptides derived therefrom, e.g., API_40, A(3142 , and other fragments, are known to be involved in the pathology of Alzheimer's disease. The A(31_42peptides are not only implicated in neurotoxicity but also are known to inhibit cholinergic transmitter function. Further, it has been determined that A(3 peptides bind to a7nACh receptors. Thus, agents which block the binding of the A(3 peptides to a-7 nAChRs are useful for treating neurodegenerative diseases.
See, e.g., WO 99/62505. In addition, stimulation a7nACh receptors can protect neurons against cytotoxicity associated with Appeptides. See, e.g., Kihara, T. et al., Ann.
Neuro1.,1997, 42, 159.

Thus, in accordance with an embodiment of the invention there is provided a method of treating and/or preventing dementia in an Alzheimer's patient which comprises administering to the subject a therapeutically effective amount of a compound according to Formulas I-IV to inhibit the binding of an amyloid beta peptide (preferably, A(3I-42) with riACh receptors, preferable a7nACh receptors, most preferably, human a7nACh receptors (as well as a method for treating and/or preventing other clinical manifestations of Alzheimer's disease that include, but are not limited to, cognitive and language deficits, apraxias, depression, delusions and other neuropsychiatric symptoms and signs, and movement and gait abnormalities).

The present invention also provides methods for treating other amyloidosis diseases, for example, hereditary cerebral angiopathy, nonneuropathic hereditary amyloid, Down's syndrome, macroglobulinemia, secondary familial Mediterranean fever, Muckle-Wells syndrome, multiple myeloma, pancreatic- and cardiac-related amyloidosis, chronic hemodialysis anthropathy, and Finnish and Iowa amyloidosis.

In addition, nicotinic receptors have been implicated as playing a role in the body's response to alcohol ingestion. Thus, agonists for a7nACh receptors can be used in the treatment of alcohol withdrawal and in anti-intoxication therapy. Thus, in accordance with an embodiment of the invention there is provided a method of treating a patient for alcohol withdrawal or treating a patient witll anti-intoxication therapy comprising administering to the patient an effective amount of a compound according to Formulas I-IV.

Agonists for the a7nACh receptor subtypes can also be used for neuroprotection against damage associated with strokes and ischemia and glutamate-induced excitotoxicity. Thus, in accordance with an embodiment of the invention there is provided a method of treating a patient to provide for neuroprotection against damage associated with strokes and ischemia and glutamate-induced excitotoxicity comprising administering to the patient an effective amount of a compound according to Formulas I-IV.

As noted above, agonists for the a7nACh receptor subtypes can also be used in the treatment of nicotine addiction, inducing smoking cessation, treating pain, and treating jetlag, obesity, diabetes, and inflammation. Thus, in accordance with an embodiment of the invention there is provided a method of treating a patient suffering from nicotine addiction, pain, jetlag, obesity, diabetes, and/or inflammation, or a method of inducing smoking cessation in a patient comprising administering to the patient an effective amount of a compound according to Formulas I-IV.

The inflammatory reflex is an autonomic nervous system response to an inflammatory signal. Upon sensing an inflammatory stimulus, the autonomic nervous system responds through the vagus nerve by releasing acetylcholine and activating nicotinic 0 receptors on macrophages. These macrophages in turn release cytokines.
Dysfunctions in this pathway have been linked to human inflammatory diseases including rheumatoid arthritis, diabetes and sepsis. Macrophages express the nicotinic 0 receptor and it is likely this receptor that mediates the cholinergic anti-inflammatory response.
Therefore, compounds with affinity for the a7nACh receptor on macrophages may be useful for human inflammatory diseases including rheumatoid arthritis, diabetes and sepsis. See, e.g., Czura, C J et al., J. Intern. Med., 2005, 257(2), 156-66.

Thus, in accordance with an embodiment of the invention there is provided a method of treating a patient (e.g., a mammal, such as a human) suffering from an inflammatory disease or disorder, such as, but not limited to, rheumatoid arthritis, diabetes or sepsis, comprising administering to the patient an effective amount of a compound according to Formulas I-IV.

In addition, due to their affinity to a7nACh receptors, labeled derivatives of the compounds of Formulas I-IV (e.g., C' I or F18labeled derivatives), can be used in neuroimaging of the receptors within, e.g., the brain. Thus, using such labeled agents in vivo imaging of the receptors can be performed using, e.g., PET imaging.

The condition of memory impairment is manifested by impairment of the ability to learn new information and/or the inability to recall previously learned information.
Memory impairment is a primary symptom of dementia and can also be a symptom associated with such diseases as Alzheimer's disease, schizophrenia, Parkinson's disease, Huntington's disease, Pick's disease, Creutzfeldt-Jakob disease, HIV, cardiovascular disease, and head trauma as well as age-related cognitive decline.

Thus, in accordance with an embodiment of the invention there is provided a method of treating a patient suffering from, for example, mild cognitive impairment (MCI), vascular dementia (VaD), age-associated cognitive decline (AACD), amnesia associated w/open-heart-surgery, cardiac arrest, and/or general anesthesia, memory deficits from early exposure of anesthetic agents, sleep deprivation induced cognitive impairment, chronic fatigue syndrome, narcolepsy, AIDS-related dementia, epilepsy-related cognitive impairment, Down's syndrome, Alcoholism related dementia, drug/substance induced memory impairments, Dementia Puglistica (Boxer Syndrome), and animal dementia (e.g., dogs, cats, horses, etc.) comprising administering to the patient an effective amount of a compound according to Formulas I-IV.

The dosages of the compounds of the present invention depend upon a variety of factors including the particular syndrome to be treated, the severity of the symptoms, the route of administration, the frequency of the dosage interval, the particular compound utilized, the efficacy, toxicology profile, pharmacokinetic profile of the compound, and the presence of any deleterious side-effects, among other considerations.

The compounds of the invention can be administered to patients, e.g., mammals, particularly humans, at typical dosage levels customary for a-7 nicotinic receptor agonists such as the known a-7 nicotinic receptor agonist compounds mentioned above.
For example, the compounds can be administered, in single or multiple doses, by oral administration at a dosage level of, for example, 0.0001-10 mg/kg/day, e.g., 0.01-10 mg/kg/day. Unit dosage forms can contain, for example, 1-200 mg of active compound.
For intravenous administration, the compounds can be administered in single or multiple dosages.

To a solution of 3-methoxythiophenol (26.7 mmol) in ether (20 mL) was added oxalyl chloride (43 mmol) dropwise. The mixture was heated at reflux for 1.5 h, cooled to rt (room temperature), and concentrated in vacuo. The resulting yellow oil was dissolved in dichloromethane (50 mL), cooled to 0 C, and was treated with aluminum chloride (32.0 mmol) in portions. The mixture was heated at reflux for 30 min, cooled to rt, and poured onto ice water with stirring. The organic layer was separated and successively washed with saturated, aqueous sodium bicarbonate, water, and brine. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by chromatography (4/1 ethyl acetate/hexane), thus providing 6-methoxy-l-benzothiophene-2,3-dione in 47% yield as an orange solid.

To a mixture of the dione (0.44 mmol) in 30% aqueous solution of ammonium hydroxide (2.0 mL) was added 35% aqueous solution hydrogen peroxide (0.2 mL) and the reaction mixture was maintained for 12 h. The precipitated pink solids were isolated by filtration, washed with water, and dried under high vacuum, thus providing the amide in 42% yield.

To a solution of the amide (5.46 mmol) in methanol (100 mL) was added 10 N
sodium hydroxide (12 mL). The mixture was heated at reflux for 12 h, cooled to rt, and was acidified to pH < 2 by the slow addition of conc. hydrochloric acid. The organic layer was extracted with dichloromethane (2x) and was dried over sodium sulfate. The crude product was purified by chromatography (300/50/1 dichloromethane/methanol/formic acid), thus providing the acid in 89% as a pink solid.

Procedure C

Procedure C provides a method for the coupling between 3-aminoquinuclidine and carboxylic acids to form carboxamide derivatives.

To a solution of the carboxylic acid (16.1 mmol) in N,N-dimethylformamide (65 mL) was added HBTU (16.1 mmol), catalytic amount of dimethylaminopyridine, N,N-diisopropylethylamine (96.6 mmol) and 4 A activated molecular sieves (2.6 g).
The reaction mixture was maintained at room temperature for 2 h under nitrogen and then 3-aminoquinuclidine dihydrochloride (16.1 mmol) was added. After 18 h, the solvent was removed under reduced pressure. The oily residue was partitioned between saturated, aqueous sodium bicarbonate (25 mL) and dichloromethane (100 mL). The aqueous layer was further extracted with 9/1 dichloromethane/methanol (5 x 100 mL) and the combined organic layers were concentrated. The residue was purified by chromatography [90/10/1 dichloromethane/methanol/ammonium hydroxide or 1/1 to 0/1 ethyl acetate/(70/30/1 ethyl acetate/methanol/ammonium hydroxide)] or by preparative HPLC, thus providing the product in 30%-70% yield.
