FIELD OF THE INVENTION
[0003] The present invention relates generally to the field of
ligands for nicotinic acetylcholine receptors (nAChR), 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 .alpha.7 nAChR subtype,
methods of preparing such compounds, compositions comprising such
compounds, and methods of use thereof.
BACKGROUND OF THF, INVENTION
[0004] There are two types of receptors for the neurotransmitter,
acetylcholine: muscarinic receptors and nicotinic receptors, based
on the selectivity of action of muscarine and nicotine,
respectively. Muscarinic receptors are G-protein coupled receptors.
Nicotinic receptors are members of the ligand-gated ion channel
family. When activated, the conductance of ions across the
nicotinic ion channels increases.
[0005] Nicotinic alpha-7 receptor protein forms a homo-pentameric
channel in vitro that is highly permeable to a variety of cations
(e.g., Ca.sup.++). Each nicotinic alpha-7 receptor has four
transmembrane domains, named M1, 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.
[0006] 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 .alpha.7 nAChR subtype, for the treatment of
disease conditions associated with defective or malfunctioning
nicotinic acetylcholine receptors.
SUMMARY OF THE INVENTION
[0007] This invention relates to novel compounds, which act as
ligands for the .alpha.7 nAChR subtype, methods of preparing such
compounds, compositions comprising such compounds, and methods of
use thereof.

[0979] and pharmaceutically acceptable salts thereof.
[0980] Preferred aspects include pharmaceutical compositions
comprising a compound of this invention and a pharmaceutically
acceptable carrier and, optionally, another active agent as
discussed below; a method of stimulating or activating inhibiting
alpha-7 nicotinic receptors, e.g., as determined by a conventional
assay or one described herein, either in vitro or in vivo (in an
animal, e.g., in an animal model, or in a mammal or in a human); a
method of treating a neurological syndrome, e.g., loss of memory,
especially long-term memory, cognitive impairment or decline,
memory impairment, etc. method of treating a disease state
modulated by nicotinic alpha-7 activity, in a mammal, e.g., a
human, e.g., those mentioned herein.
[0981] 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.
[0982] The synthesis of similar compounds is disclosed in copending
application Ser. No. 11/018,429, filed Dec. 22, 2004, the entire
disclosure of which is hereby incorporated by reference.
[0983] 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.;
at al. J. Am. Chem. Soc. 1952, 74, 2009).
[0984] Some substituted indazole-3-acids were prepared by modifying
existing indazole acids or esters. For example,
5-nitroindazole-3-acid was prepared by nitration of indazole-3-acid
(Kamm, O.; Segur, J. B. Org. Syn. Coll. Vol 1. 1941, 372).
6-Nitroindazole-3-acid was prepared from 3-iodo-6-nitroindazole
using copper (I) cyanide followed by hydrolysis. Some non-aromatic
heterocyclic derivatives were prepared from the 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
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).
[0985] Some substituted indazole-3-acids were prepared from simple
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 used in that preparation 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.
[0986] The benzisoxazole- and benzisoxazolecarboxylic acids were
prepared using similar strategies outlined for the indazole acids.
For example, ethyl 6-bromobenzisoxazole-3-carboxylate was prepared
from 2,5-dibromonitrobenzene by reaction with diethyl malonate,
saponification and decarboxylation, and reaction with
isoamylnitrite. Ethyl benzisoxazole-3-carboxylate was obtained by
hydrogenolysis of the 6-bromo derivative.
3-Benzisothiazolecarboxylic acid was prepared from thiophenol by
reaction with oxalyl chloride and aluminum chloride followed by
treatment with hydroxylamine, hydrogen peroxide, and sodium
hydroxide.
[0987] Bicycloamines that can be used in the preparation of the
bicyclobase amides are commercially available, can be prepared by
known procedures described in the literature, or as described
below. For example, 2-Methyl-2-azabicyclo[2.2.2]octan-5-amine was
obtained by the reduction of the
2-Boc-2-azabicyclo[2.2.2]octan-5-amine (J. Med. Chem. 1973, 16,
853; Synthesis 1979, 50; WO97/40016).
2-Methyl-2-azabicyclo[2.2.1]heptan-5-amine (Tetrahedron 1998, 54,
8047-8054; J. Med. Chem. 1992, 35, 2184-2191),
octahydroindolizin-6-amine (U.S. Pat. No. 4,213,983).
2-azabicyclo[2.2.1]heptan-5-amine (J. Med. Chem. 1990, 33, 1924),
8-azabicyclo[32.1]octan-3-amine (WO38680A1; J. Med. Chem., 1993,
36, 3707; J. Med. Chem. 2001, 44, 1815), and
9-azabicyclo[3.3.1]nonan-3-amine (WO38680A1; J. Med. Chem. 1993,
36, 3707; J. Med. Chem. 2001, 44, 1815) were prepared according to
literature procedures. 8-Methyl-8-azabicyclo[3.2.1]octan-3-amine
was obtained from commercial sources as a variable mixture of endo-
and exo-isomers whereas pure exo- and pure endo-isomers were
prepared according to the literature (J. Med. Chem. 1998, 41, 988).
3,8-Dimethyl-8-azabicyclo[3.2.1]octan-3-amine was prepared from
3-aminotropane by exposure to di-tert-butyl dicarbonate followed by
lithium aluminum hydride reduction.
endo-9-Methyl-9-azabicyclo[3.3.1]nonan-3-amine was obtained by the
acid hydrolysis of granisetron
exo-9-Methyl-9-azabicyclo[3.3.1]nonan-3-amine and a mixture of
endo- and exo-9-Methyl-9-azabicyclo[3.3.1]nonan-3-amine may be
obtained according to the procedures set forth in European Patent
Application No. 0 013 138 A1.
8-Methyl-3,8-diazabicyclo[3.2.1]octane and
3-methyl-3,8-diazabicyclo[3.2.1]octane were prepared from the
commercially available 8-Boc protected base by lithium aluminum
hydride reduction and reductive alkylation followed by
deprotection, respectively.
[0988] The bicyclobase amide can be prepared by the coupling
reaction of acids with the bicycloamine and HBTU or HOBt and EDCI
in DMF, or by converting the acids to the corresponding acid
chloride and then reaction with the bicycloamine (Macor, J. E.;
Gurley, D.; Lanthorn, T.; Loch, J.; Mack, R. A.; Mullen, G.; Tran,
O.; Wright, N.; and J. E. Macor et al., "The 5-HT3-Antagonist
Tropisetron (ICS 205-930) is a Potent and Selective .alpha.-7
Nicotinic Receptor Partial Agonist," Bioorg. Med. Chem. Lett. 2001,
9, 319-321). The couplings are generally performed at room
temperatures for 18-24 hours. Thioamide analogs can be prepared
from the amides by reaction with Lawesson's reagent (Wipf P.; Kim,
Y.; Goldstein, D. M., J. Am. Chem. Soc., 1995, 117, 11106).
Bicyclobase methylenamine analogs may be prepared from bicyclobase
amides by standard reduction procedures as described, for example,
below. The resultant adducts can be isolated and purified by
standard techniques, such as chromatography or recrystallization,
practiced by those skilled in the art.
[0989] The nicotinic ligands can, alternatively, be prepared by
modification of other nicotinic ligands. For example, the
5-(3-thiophene) ligand was prepared from the corresponding bromide
ligand by a palladium-catalyzed cross-coupling reaction. Other
halogen-substituted ligands served as precursors for modified
ligands where appropriate. As a final example, urea analogs were
prepared from aniline substituted analogs.
[0990] One of ordinary skill in the art will recognize that
compounds of Formulas I, II, or III can exist in different
tautomeric and geometrical isomeric forms. For example, compound
containing the 8-methyl-5-azabicyclo[3.2.1]octan-3-amino, or
9-methyl-9-azabicyclo[3.3.1]non-3-amino structures can be in the
form of the endo isomer, exo isomer, or mixtures thereof. 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%.
[0991] 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, II,
or III can likewise be obtained by utilizing optically active
starting materials in chiral synthesis processes under reaction
conditions which do not cause racemization.
[0992] 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 .sup.2H, .sup.3H, .sup.11C,
.sup.13C and/or .sup.14C. In one particular embodiment, the
compounds are deuterated. Such deuterated forms can be made the
procedure described in U.S. Pat. Nos. 5,846,514 and 6,334,997. As
described in U.S. Pat. Nos. 5,846,514 and 6,334,997, deuteration
can improve the efficacy and increase the duration of action of
drugs.
[0993] Deuterium substituted compounds can be synthesized using
various methods such as described in: Dean, Dennis C.; Editor.

[0994] Where applicable, the present invention also relates to
useful forms of the compounds as disclosed herein, such as
pharmaceutically acceptable salts or prodrugs of all the compounds
of the present invention for which salts or prodrugs can be

pivalates, propionates, succinates, tartrates, thiocyanates,
tosylates, mesylates and undecanoates.
[0996] 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. The free base can then, if desired, be
converted to a pharmaceutically acceptable acid addition salt.
[0997] 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-III, containing, for example, one or more
pharmaceutically acceptable carriers.
[0998] 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).
[0999] 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, intravenously, intramuscularly, intrasternally and
by infusion) by inhalation, rectally, vaginally, topically and by
ocular administration.
[1000] 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 invention 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.
[1001] 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.
[1002] 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.
[1003] 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.
[1004] 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.
[1005] 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 .alpha.-7 agonists, PDE4 inhibitors, calcium
channel blockers, muscarinic m1 and m2 modulators, adenosine
receptor modulators, amphakines 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.
[1006] The compounds of the invention can be used in conjunction
with "positive modulators" which enhance the efficacy of nicotinic
receptor agonists. Set, 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.
[1007] Further the compounds may be used in conjunction with
compounds that bind to A.beta. peptides and thereby inhibit the
binding of the peptides to .alpha.7nACh receptor subtypes. See,
e.g., WO 99/62505.
[1008] The present invention further includes methods of treatment
that involve activation of .alpha.-7 nicotinic receptors. Thus, the
present invention includes methods of selectively
activating/stimulating .alpha.-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, II, or
III, alone or as part of a formulation, as disclosed herein.
[1009] 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, II, or III. Preferably, the disease state involves
decreased nicotinic acetylcholine receptor activity.
[1010] In accordance with a method aspect of the invention there is
provided a method for the treatment or prophylaxis of a disease or
condition resulting from dysfunction of nicotinic acetylcholine
receptor transmission in a patient (e.g., a mammal such as a human)
comprising administering an effective amount of a compound
according to Formulas I, II, or III.
[1011] In accordance with a method aspect of the invention there is

an effective amount of a compound according to Formulas I, II, or
III.
[1012] In accordance with a method aspect of the invention there is

receptor transmission in a patient (e.g., a mammal such as a human)
comprising administering an amount of a compound according to
Formulas I, II or III effective to activate .alpha.7nACh
receptors.
[1013] In accordance with another method aspect of the invention
there is provided a method for the treatment or prophylaxis of a
psychotic disorder, a cognition impairment (e.g., memory
impairment), or neurodegenerative disease in a patient (e.g., a
mammal such as a human) comprising administering an effective
amount of a compound according to Formulas I, II, or III.
[1014] In accordance with another method aspect of the invention
there is provided a method for the treatment or prophylaxis of a
disease or condition resulting from loss of cholinergic synapses in
a patient (e.g., a mammal such as a human) comprising administering
an effective amount of a compound according to Formulas I, II, or
III.
[1015] In accordance with another method aspect of the invention
there is provided a method for the treatment or prophylaxis of a
neurodegenerative disorder by activation of .alpha.7nACh receptors
in a patient (e.g., a mammal such as a human) comprising
administering an effective amount of a compound according to
Formulas I, II, or III.
[1016] In accordance with another method aspect of the invention
there is provided a method for protecting neurons in a patient
(e.g., a mammal such as a human) from neurotoxicity induced by
activation of .alpha.7nACh receptors comprising administering an
effective amount of a compound according to Formulas I, II, or
III.
[1017] In accordance with another method aspect of the invention
there is provided a method for the treatment or prophylaxis of a
neurodegenerative disorder by inhibiting the binding of A.beta.
peptides to .alpha.7nACh receptors in a patient (e.g., a mammal
such as a human) comprising administering an effective amount of a
compound according to Formulas I, II, or III.
[1018] In accordance with another method aspect of the invention
there is provided a method for protecting neurons in a patient
(e.g., a mammal such as a human) from neurotoxicity induced by
A.beta. peptides comprising administering an effective amount of a
compound according to Formulas I, II, or III.
[1019] In accordance with another method aspect of the invention
there is provided a method for alleviating inhibition of
cholinergic function induced by A.beta. peptides in a patient
(e.g., a mammal such as a human) comprising administering an
effective amount of a compound according to Formulas I, II, or
III.
[1020] 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.
[1021] 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
.alpha.7nACh 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
(.alpha.2-.alpha.9 and .beta.2-.beta.4). There are also five
further subunits expressed in the peripheral nervous system
(.alpha.1, .beta.1, .gamma., .delta., .epsilon.).
[1022] The nACh receptor subtypes can be homopentameric or
heteropentameric. The subtype which has received considerable
attention is the homopentameric .alpha.7 receptor subtype formed
from five .alpha.7 subunits. The .alpha.7nACh receptors exhibit a
high affinity for nicotine (agonist) and for .alpha.-bungarotoxin
(antagonist). Studies have shown the .alpha.7nACh 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 .alpha.7nACh receptor agonists, especially
selective agonists, which are less toxic or exhibit fewer side
effects than nicotine.
[1023] 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., U.S. Pat.
No. 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., U.S. Pat. No. 5,741,802), is a selective
partial .alpha.7nACh 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 .alpha.7nACh
receptors. See, e.g., Stevens at al., Psychopharmacology, 136:
320-27 (1998).
[1024] Another compound which is known to be a selective
.alpha.7nACh receptor agonist is Tropisetron, i.e., 1.alpha.H,
5.alpha.H-tropan-3.alpha.-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 Agonist. Bioorg. Med.
Chem. Lett. 2001, 319-321).
[1025] Agents that bind to nicotinic acetylcholine receptors have
been indicated as useful in the treatment and/or prophylaxis of
various diseases and conditions, particularly psychotic diseases,
neurodegenerative diseases involving a dysfunction of the
cholinergic system, and conditions of memory and/or cognition
impairment, including, for example, schizophrenia, anxiety, mania,
depression, manic depression [examples of psychotic disorders],
Tourette's syndrome, Parkinson's disease, Huntington's disease
[examples of neurodegenerative diseases], cognitive disorders (such
as Alzheimer's disease, Lewy Body Dementia, Amyotrophic Lateral
Sclerosis, memory impairment, memory loss, cognition deficit,
attention deficit, Attention Deficit Hyperactivity Disorder), and
other uses such as treatment of nicotine addiction, inducing
smoking cessation, treating pain (i.e., analgesic use), providing
neuroprotection, and treating jetlag. See, e.g., WO 97/30998; WO
99/03850; WO 00/4204; WO 01/36417; Holladay et al., J. Med. Chem.,
40:26, 4169-94 (1997); Schmitt et al., Annual Reports Med. Chem.,
Chapter 5, 41-51 (2000); Stevens et al., Psychopharmatology, (1998)
136: 320-27; and Shytle et al., Molecular Psychiatry, (2002), 7,
pp. 525-535.
[1026] Thus, in accordance with the invention, there is provided a
method of treating a patient, especially a human, suffering from
psychotic diseases, neurodegenerative diseases involving a
dysfunction of the cholinergic system, and conditions of memory
and/or cognition impairment, including, for example, schizophrenia,
anxiety, mania, depression, manic depression [examples of psychotic
disorders], Tourette's syndrome, Parkinson's disease, Huntington's
disease [examples of neurodegenerative diseases], and/or cognitive
disorders (such as Alzheimer's disease, Lewy Body Dementia,
Amyotrophic Lateral Sclerosis, memory impairment, memory loss,
cognition deficit, attention deficit, Attention Deficit
Hyperactivity Disorder) comprising administering to the patient an
effective amount of a compound according to Formulas I, II, or
III.
[1027] Neurodegenerative disorders included within the methods of
the present invention include, but are not limited to, treatment
and/or prophylaxis of Alzheimer's diseases, Pick's disease, diffuse
Lewy Body disease, progressive supranuclear palsy (Steel-Richardson
syndrome), multisystem degeneration (Shy-Drager syndrome), motor
neuron diseases including amyotrophic lateral sclerosis,
degenerative ataxias, cortical basal degeneration,
ALS-Parkinson's-Dementia complex of Guam, subacute sclerosing
panencephalitis, Huntington's disease, Parkinson's disease,
synucleinopathies, primary progressive aphasia, striatonigral
degeneration, Machado-Joseph disease/spinocerebellar ataxia type 3,

sclerosis, familial spastic paraplegia, Werdnig-Hoffmann disease,
Kugelberg-Welander disease, Tay-Sach's disease, Sandhoff disease,
familial spastic disease, Wohlfart-Kugelberg-Welander disease,
spastic paraparesis, progressive multifocal leukoencephalopathy,
priori diseases (such as Creutzfeldt-Jakob,
Gerstmann-Straussler-Seheinker disease, Kuru and fatal familial
insomnia), and neurodegenerative disorders resulting from cerebral
ischemia or infarction including embolic occlusion and thrombotic
occlusion as well as intracranial hemorrhage of any type
(including, but not limited to, epidural, subdural, subarachnoid
and intracerebral), and intracranial and intravertebral lesions
(including, but not limited to, contusion, penetration, shear,
compression and laceration).
[1028] In addition, .alpha.7nACh receptor agonists, such as the
compounds of the present invention can be used to treat age-related
dementia and other dementias and conditions with memory loss
including age-related memory loss, senility, vascular dementia,
diffuse white matter disease (Binswanger's disease), dementia of
endocrine or metabolic origin, dementia of head trauma and diffuse
brain damage, dementia pugilistica and frontal lobe dementia. See,
e.g., WO 99/62505. 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, II, or
III.
[1029] Thus, in accordance with a further embodiment, the present
invention includes methods of treating patients suffering from
memory impairment due to, for example, mild cognitive impairment
due to aging, Alzheimer's disease, schizophrenia, Parkinson's
disease, Huntington's disease, Pick's disease, Creutzfeld-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, II, or III.
[1030] Amyloid precursor protein (APP) and A.beta. peptides derived
therefrom, e.g., A.beta..sub.1-40, A.beta..sub.1-42, and other
fragments, are known to be involved in the pathology of Alzhemier's
disease. The A.beta..sub.1-42 peptides are not only implicated in
neurotoxicity but also are known to inhibit cholinergic transmitter
function. Further, it has been determined that A.beta. peptides
bind to .alpha.7nACh receptors. Thus, agents which block the
binding of the A.beta. peptides to .alpha.-7 nAChRs are useful for
treating neurodegenerative diseases. See, e.g., WO 99/62505. In
addition, stimulation .alpha.7nACh receptors can protect neurons
against cytotoxicity associated with A.beta. peptides. See, e.g.,
Kihara, T. et al., Ann. Neurol., 1997, 42, 159.
[1031] 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, II, or III to inhibit the binding of an amyloid beta
peptide (preferably, A.beta..sub.1-42) with nACh receptors,
preferable .alpha.7nACh receptors, most preferably, human
.alpha.7nACh 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).
[1032] 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.
[1033] In addition, nicotinic receptors have been implicated as
playing a role in the body's response to alcohol ingestion. Thus,
agonists for .alpha.7nACh 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 with anti-intoxication therapy comprising administering to
the patient an effective amount of a compound according to Formulas
I, II, or III.
[1034] Agonists for the .alpha.7nACh 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, II, or III.
[1035] As noted above, agonists for the .alpha.7nACh 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
and/or diabetes, 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, II, or III.
[1036] 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 .alpha.7
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 .alpha.7 receptor and it
is likely this receptor that mediates the cholinergic
anti-inflammatory response. Therefore, compounds with affinity for
the .alpha.7nACh 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.
[1037] 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, 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, II, or III.
[1038] In addition, due to their affinity to .alpha.7nACh
receptors, labeled derivatives of the compounds of Formulas I, II,
or III (e.g., C.sup.11 or F.sup.18 labeled 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.
[1039] 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, Creutzfeld-Jakob disease, HIV, cardiovascular disease, and
head trauma as well as age-related cognitive decline.
[1040] 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, II, or III.
[1041] 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.
[1042] The compounds of the invention can be administered to
patients, e.g., mammals, particularly humans, at typical dosage
levels customary for .alpha.-7 nicotinic receptor agonists such as
the known .alpha.-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, 0.000140 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.
[1043] In carrying out the procedures of the present invention it
is of course to be understood that reference to particular buffers,
media, reagents, cells, culture conditions and the like are not
intended to be limiting, but are to be read so as to include all
related materials that one of ordinary skill in the art would
recognize as being of interest or value in the particular context
in which that discussion is presented. For example, it is often
possible to substitute one buffer system or culture medium for
another and still achieve similar, if not identical, results. Those
of skill in the art will have sufficient knowledge of such systems
and methodologies so as to be able, without undue experimentation,
to make such substitutions as will optimally serve their purposes
in using the methods and procedures disclosed herein.
[1044] The present invention will now be further described by way
of the following non-limiting examples. In applying the disclosure
of these examples, it should be kept clearly in mind that other and
different embodiments of the methods disclosed according to the
present invention will no doubt suggest themselves to those of
skill in the relevant art.
[1045] In the foregoing and in the following examples, all
temperatures are set forth uncorrected in degrees Celsius; and,
unless otherwise indicated, all parts and percentages are by
weight.
[1046] The entire disclosures of all applications, patents and
publications, cited above and below, are hereby incorporated by
reference.
[1047] Using the following procedures and further procedures
described below, the following compounds in Examples 1-191 were
prepared.

[1048] All spectra were recorded at 300 MHz on a Bruker Instruments
NMR unless otherwise stated. Coupling constants (J) are in Hertz
(Hz) and peaks are listed relative to TMS (.delta. 0.00 ppm).
Microwave reactions were performed using a Personal Chemistry
Optimizer.TM. microwave reactor in 2.5 mL or 5 mL Personal
Chemistry microwave reactor vials. All reactions were performed at
200.degree. C. for 600 s with the fixed hold time ON unless
otherwise stated. Sulfonic acid ion exchange resins (SCX) were
purchased from Varian Technologies. Analytical HPLC was performed
on 4.6 mm.times.100 mm Xterra RP.sub.18 3.5.mu. columns using a
gradient of 20/80 to 80/20 water (0.1% formic acid)/acetonitrile
(0.1% formic acid) over 6 min. Preparative HPLC was performed on 30
mm.times.100 mm Xtera Prep RP.sub.18 5.mu. columns using an 8 min
gradient of 95/5 to 20/80 water (0.1% formic acid)/acetonitrile
(0.1% formic acid). Hydrochloride salts of the bicycle amides were
prepared by adding an ethereal solution of hydrochloric acid to a

the resulting precipitate.
Acid Preparations.
[1049] The following procedures (1-9) detail the preparation of the
indazole and benzisothiazole acids that were not commercially
available.
Procedure 1:
[1050] Procedure 1 provides a method for the preparation of
6-nitroindazole-3-acid and the coupling with bicyclobases to form
nitro-substituted derivatives.
[1051] A 5 mL microwave reaction vessel was charged with
3-iodo-6-nitroindazole (1 mmol), copper (I) cyanide (2 mmol) and
N,N-dimethylformamide (3 mL). The vessel was sealed and subjected
to microwave irradiation at 185.degree. C. for 600 sec. The
reaction mixture was partitioned between ethyl acetate (100 mL) and
water (100 mL) and the mixture was filtered through Celite. The
organic layer was collected, washed with brine, dried (magnesium
sulfate), and concentrated to give 122 mg of a 10/1 mixture of
3-cyano-6-nitroindazole and 6-nitroindazole as a yellow solid. The
10/1 mixture of 3-cyano-6-nitroindazole and 6-nitroindazole was
dissolved in 10 N sodium hydroxide and the bright orange solution
was heated at 100.degree. C. for 1 h. The mixture was allowed to
cool to room temperature and carefully acidified (pH=1) with 3 N

[1056] Ethyl indazole-3-carboxylate (73.7 mmol) was dissolved in 20
mL concentrated sulfuric acid and the reaction mixture was cooled

Procedure 3:
[1060] Procedure 3 provides a method for the preparation of isatins
from anilines and the conversion of the isatins to the
corresponding indazole-3-carboxylic acids.
[1061] A solution of the substituted aniline (565 mL) in 6N
hydrochloric acid (106 mL) was added to a suspension of
2,2,2-trichloro-1-ethoxyethanol (678 mL) and sodium sulfate (3.15
mol) in water (1.4 L) and the reaction mixture was stirred
vigorously for 1 h. A solution of hydroxylamine hydrochloride (2.08
mol) in water (650 mL) was added in one portion and the reaction
mixture was heated at 80.degree. C. for 1.5 h. The reaction mixture
was cooled to 10.degree. C. and the precipitated solids were
collected by filtration, washed with water, and dried to provide
the amide in 91% yield.
[1062] The amide was added to sulfuric acid (1.9 L) and the
reaction mixture was heated at 60.degree. C. for 6 h. The reaction
mixture was allowed to cool to room temperature and was cautiously
poured onto ice (7 kg). The precipitated solids were collected by
filtration, washed with water, and dried to provide the isatin in
61% yield.
[1063] The conversion of the substituted isatin to the
corresponding indazole-3-carboxylic acids is essentially the same
method as described for indazole-3-carboxylic acid: Snyder, H. R.,
et. al. J. Am. Chem. Soc. 1952, 74, 2009. The substituted isatin
(22.1 mmol) was diluted with 1 N sodium hydroxide (24 mL) and was
heated at 50.degree. C. for 30 min. The burgundy solution was
allowed to cool to rt and was maintained for 1 h. The reaction
mixture was cooled to 0.degree. C. and was treated with a 0.degree.
C. solution of sodium nitrite (22.0 mmol) its water (5.5 mL). This
solution was added through a pipet submerged below the surface of a
vigorously stirred solution of sulfuric acid (2.3 mL) in water (45
mL) at 0.degree. C. The addition took 15 min and the reaction was
maintained for an additional 30 min. A cold (0.degree. C.) solution
of tin (II) chloride dihydrate (52.7 mmol) in concentrated
hydrochloric acid (20 mL) was added to the reaction mixture over 10
min and the reaction mixture was maintained for 60 min. The
precipitated solids were isolated by filtration, washed with water,
and dried to give a quantitative mass balance. This material was of
sufficient purity (.sup.1H NMR and LC/MS) to use in the next step
without further purification. Alternatively, the acid was
recrystallized from acetic acid to provide pure material.
[1064] The following acids were prepared using this method: [1065]
5-Fluoro-1H-indazole-3-acid. [1066] 5-Bromo-1H-indazole-3-acid.

Procedure 4:
[1070] Procedure 4 provides a preparation of substituted
benzisothiazole-3-carboxylic acids from the corresponding
thiophenols.
[1071] 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, and concentrated in
vacuo. The resulting yellow oil was dissolved in dichloromethane
(50 mL), cooled to 0.degree. 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 sedum 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-1-benzothiophene-2,3-dione in 47% yield as an orange
solid.
[1072] 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.
[1073] To a solution of the amide (5.46 mind) 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 (2.times.) 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.
[1074] The following acids were prepared by this method: [1075]
Benzisothiazole-3-carboxylic acid. [1076]
6-Bromobenzisothiazole-3-carboxylic acid. [1077]

Procedure 5:
[1081] Procedure 5 provides a method for the coupling between
brominated benzisothiazole-3-carboxylic esters and brominated
indazole-3-carboxylic esters and Grignard reagents to form alkyl-
and heterocycle-substituted acids.
[1082] A 0.5 M solution of the Grignard reagent (25.0 mmol, 3.7 eq)
in tetrahydrofuran was diluted with tetrahydrofuran (60 mL) and
treated with a 0.5 M solution of zinc chloride (25.0 mmol, 3.7 eq)
in tetrahydrofuran at rt. After 10 min, the brominated ethyl
benzisothiazole-3-carboxylate (0.30 mmol) and
bis(triphenylphosphine)palladium (II) chloride (0.95 mmol, 0.1 eq)
were added to the suspension. The reaction mixture was maintained
for 1 h at ambient temperature then at 65.degree. C. for 1 h. The
reaction was quenched with saturated ammonium chloride and was
extracted with dichloromethane (3 x). The extracts were dried over
sodium sulfate and concentrated to dryness. The residue was
purified by chromatography using a gradient of 100/0 to 90/10
dichloromethane/methanol to provide the cyclopropyl-substituted
amide. The amide was dissolved in a mixture of
methanol/tetrahydrofuran/water (90/10/20 mL) and was treated with
sodium hydroxide (5.8 g). The mixture was heated at reflux for 12
h, cooled to rt, filtered, and was acidified to pH<2 by the slow
addition of conc. hydrochloric acid. The aqueous layer was
extracted with ethyl acetate (2.times.) and was dried over sodium
sulfate. Concentration of the extracts gave the acid in 38% yield.
The acid was coupled to the bicyclobases according to procedure
A.
[1083] This procedure was used, with slight modifications, to
derivatize brominated indazole-3-carboxylic esters and carboxamides
with various Grignard reagents. The Grignard reagent of thiazole is
commercially available. Alternatively, the aryllithium and the
corresponding arylzinc reagent can be generated according to the
procedure outlined by Reeder, M. R.; et. al. Org. Proc. Res. Devel.

6-(3,6-dihydro-2H-pyran-4-yl)-1H-indazole-3-carboxylic acid (76%).
The acids were coupled with the bicyclobase according to procedure
A.
[1126] The following acids were prepared using this method: [1127]
5-(3,6-Dihydro-2H-pyran-4-yl)-1H-indazole-3-carboxylic acid, [1128]
6-(3,6-Dihydro-2H-pyran-4-yl)-1H-indazole-3-carboxylic acid.
Representative Procedure A.
[1129] Procedure A provides a method for the coupling between
bicyclobases and carboxylic acids to form carboxamide
derivatives.
Example 1
N-(8-Methyl-8-azabicyclo[3.2.1]oct-3-yl)-1,2-benzisothiazole-3-carboxamide
##STR00047##
[1131] To a solution of benzisothiazole-3-carboxylic acid (0.93
mmol) in tetrahydrofuran (10 mL) and N,N-dimethylformamide (1 mL)
was added N,N-diisopropylethylamine (2.87 mmol) and
8-methyl-8-azabicyclo[3.2.1]octan-3-amine dihydrochloride (0.99
mmol). The reaction mixture was maintained at room temperature for
30 min under nitrogen and then HATU (1.00 mmol) was added. After 18
h, the reaction mixture was partitioned between saturated aqueous
potassium carbonate solution and 95/5 dichloromethane/methanol. The
aqueous layer was extracted with 95/5 dichloromethane/methanol
(2.times.), and the combined organic layers were washed with brine,
dried over sodium sulfate, filtered and concentrated in vacuo. The
residue was purified by silica gel flash column chromatography
using a mixture of [90/10/1 dichloromethane/methanol/ammonium
hydroxide] as the eluent, thus providing the product in 20% yield.
Alternatively, the residues were purified by preparative HPLC.

tris(dibenzylideneacetone)dipalladium (0) (0.0289 mmol),
tri-tert-butylphosphine tetrafluoroborate (0.0579 mmol), and
potassium carbonate (0.810 mmol). The vessel was evacuated,
back-filled with argon gas, and the contents diluted with
N,N-dimethylformamide (5.0 mL). The vessel was sealed and subjected
to microwave irradiation at 200.degree. C. for 600 s. The contents
of the reaction were filtered through Celite (methanol wash) and
loaded on a 5 g SCX column. The column was washed with methanol (50
mL) and the product was eluted with 2 M ammonia in methanol and
concentrated. The residue was purified by chromatography [1/1 to
0/1 ethyl acetate/(70/30/1 ethyl acetate/methanol/ammonium
hydroxide)] followed by preparative HPLC, thus providing the
product in 4% yield. .sup.1H NMR (CD.sub.3OD) .delta. 8.51 (s, 1H),
