Description: QUJNUCLIDINE-SUBSTΓΓUTED HETEROARYL MOIETIES FOR TREATEMENT OF DISEASE FIELD OF INVENTION Nicotinic acetylcholine receptors (nAChRs) play a large role in central nervous system (CNS) activity. Particularly, they are known to be involved in cognition, learning, mood, emotion, and neuroprotection. There are several types of nicotinic acetylcholine receptors, and each one appears to have a different role in regulating CNS function. Nicotine affects all such receptors, and has a variety of activities. Unfortunately, not all of the activities are desirable. In fact, one of the least desirable properties of nicotine is its addictive nature and the low ratio between efficacy and safety. The present invention relates to molecules that have a greater effect upon the al nAChRs as compared to other closely related members of this large ligand-gated receptor family. Thus, the invention provides compounds that are active drug molecules with fewer side effects.

For parenteral administration, saline solution, dextrose solution, or water may be used as a suitable carrier. Formulations for parenteral administration may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art. The serotonin type 3 receptor (5HT 3 R) is a member of a superfamily of ligand- gated ion channels, which includes the muscle and neuronal nAChR, the glycine receptor, and the γ-aminobutyric acid type A receptor. Like the other members of this receptor superfamily, the 5HT 3 R exhibits a large degree of sequence homology with 7 nAChR but functionally the two ligand-gated ion channels are very different. For example, al nAChR is rapidly inactivated, is highly permeable to calcium and is activated by acetylcholine and nicotine. On the other hand, 5HT 3 R is inactivated slowly, is relatively impermeable to calcium and is activated by serotonin. These experiments suggest that the al nAChR and 5HT 3 R proteins have some degree of homology, but function very differently. Indeed the pharmacology of the channels is very different. For example, Ondansetron, a highly selective 5HT R antagonist, has little activity at the al nAChR. The converse is also true. For example, GTS-21, a highly selective α7 nAChR agonist, has little activity at the 5HT R. al nAChR is a ligand-gated Ca ++ channel formed by a homopentamer of al subunits. Previous studies have established that -bungarotoxin (α-btx) binds selectively to this homopetameric, al nAChR subtype, and that al nAChR has a high affinity binding site for both α-btx and methyllycaconitine (MLA). al nAChR is expressed at high levels in the hippocampus, ventral tegmental area and ascending cholinergic projections from nucleus basilis to thalamocortical areas, al nAChR agonists increase neurotransmitter release, and increase cognition, arousal, attention, learning and memory. Data from human and animal pharmacological studies establish that nicotinic cholinergic neuronal pathways control many important aspects of cognitive function including attention, learning and memory (Levin, E.D., Psychopharmacology, 108:417-31, 1992; Levin, E.D. and Simon B.B., Psychopharmacology, 138:217-30, 1998). For example, it is well known that nicotine increases cognition and attention in humans. ABT-418, a compound that activates α4β2 and al nAChR, improves cognition and attention in clinical trials of Alzheimer's disease and attention-deficit disorders (Potter, A. et. al., Psychopharmacology (Bed)., 142(4): 334-42, Mar. 1999; Wilens, T. E. et. al., Am. J. Psychiatry, 156(12): 1931-7, Dec. 1999). It is also clear that nicotine and selective but weak al nAChR agonists increase cognition and attention in rodents and non-human primates. Schizophrenia is a complex multifactorial illness caused by genetic and non- genetic risk factors that produce a constellation of positive and negative symptoms. The positive symptoms include delusions and hallucinations and the negative symptoms include deficits in affect, attention, cognition and information processing. No single biological element has emerged as a dominant pathogenic factor in this disease. Indeed, it is likely that schizophrenia is a syndrome that is produced by the combination of many low penetrance risk factors. Pharmacological studies established that dopamine receptor antagonists are efficacious in treating the overt psychotic features (positive symptoms) of schizophrenia such as hallucinations and delusions. Clozapine, an "atypical" antipsychotic drug, is novel because it is effective in treating both the positive and some of the negative symptoms of this disease. Clozapine' s utility as a drug is greatly limited because continued use leads to an increased risk of agranulocytosis and seizure. No other antipsychotic drag is effective in treating the negative symptoms of schizophrenia. This is significant because the restoration of cognitive functioning is the best predictor of a successful clinical and functional outcome of schizophrenic patients (Green, M.F., Am J Psychiatry, 153:321- 30, 1996). By extension, it is clear that better drugs are needed to treat the cognitive disorders of schizophrenia in order to restore a better state of mental health to patients with this disorder. One aspect of the cognitive deficit of schizophrenia can be measured by using the auditory event-related potential (P50) test of sensory gating. In this test, electroencepholographic (EEG) recordings of neuronal activity of the hippocampus are used to measure the subject's response to a series of auditory "clicks" (Adler, L.E. et. al., Biol. Psychiatry, 46:8-18, 1999). Normal individuals respond to the first click with greater degree than to the second click. In general, schizophrenics and schizotypal patients respond to both clicks nearly the same (Cullum, CM. et. al., Schizophr. Res., 10:131-41, 1993). These data reflect a schizophrenic's inability to "filter" or ignore unimportant information. The sensory gating deficit appears to be one of the key pathological features of this disease (Cadenhead, K.S. et. al., Am. J. Psychiatry, 157:55-9, 2000). Multiple studies show that nicotine normalizes the sensory deficit of schizophrenia (Adler, L.E. et. al., Am. J. Psychiatry, 150: 1856-61, 1993). Pharmacological studies indicate that nicotine's effect on sensory gating is via the al nAChR (Adler, L.E. et. al., Schizophr. Bull., 24: 189-202, 1998). Indeed, the biochemical data indicate that schizophrenics have 50% fewer of al nAChR receptors in the hippocampus, thus giving a rationale to partial loss of al nAChR functionality (Freedman, R. et. al., Biol. Psychiatry, 38:22-33, 1995). Interestingly, genetic data indicate that a polymorphism in the promoter region of the al nAChR gene is strongly associated with the sensory gating deficit in schizophrenia (Freedman, R. et. al., Proc. Natl. Acad. Sci. USA, 94(2):587-92, 1997; Myles-Worsley, M. et. al, Am. J. Med. Genet, 88(5):544-50, 1999). To date, no mutation in the coding region of the α7 nAChR has been identified. Thus, schizophrenics express the same α7 nAChR as non-schizophrenics. Selective α7 nAChR agonists may be found using a functional assay on FLIPR (see WO 00/73431 A2). FLIPR is designed to read the fluorescent signal from each well of a 96 or 384 well plate as fast as twice a second for up to 30 minutes. This assay may be used to accurately measure the functional pharmacology of α7 nAChR and 5HT 3 R. To conduct such an assay, one uses cell lines that expressed functional forms of the α7 nAChR using the α7/5-HT 3 channel as the drug target and cell lines that expressed functional 5HT 3 R. In both cases, the ligand-gated ion channel was expressed in SH-EPl cells. Both ion channels can produce robust signal in the FLIPR assay. The compounds of the present invention are α7 nAChR agonists and may be used to treat a wide variety of diseases. For example, they may be used in treating schizophrenia, and psychosis. Schizophrenia is a disease having multiple aspects. Currently available drugs are generally aimed at controlling the positive aspects of schizophrenia, such as delusions. One drug, Clozapine, is aimed at a broader spectrum of symptoms associated with schizophrenia. This drug has many side effects and is thus not suitable for many patients. Thus, there is a need for a drug to treat the cognitive and attention deficits associated with schizophrenia. Similarly, there is a need for a drug to treat the cognitive and attention deficits associated with schizoaffective disorders, or similar symptoms found in the relatives of schizophrenic patients. Psychosis is a mental disorder characterized by gross impairment in the patient's perception of reality. The patient may suffer from delusions, and hallucinations, and may be incoherent in speech. His behavior may be agitated and is often incomprehensible to those around him. In the past, the term psychosis has been applied to many conditions that do not meet the stricter definition given above. For example, mood disorders were named as psychoses. There are a variety of antipsychotic drugs. The conventional antipsychotic drugs include Chlo romazine, Fluphenazine, Haloperidol, Loxapine, Mesoridazine, Molindone, Peiphenazine, Pimozide, Thioridazine, Thiothixene, and Trifluoperazine. These drugs all have an affinity for the dopamine 2 receptor. These conventional antipsychotic drugs have several side effects, including sedation, weight gain, tremors, elevated prolactin levels, akathisia (motor restlessness), dystonia and muscle stiffness. These drugs may also cause tardive dyskinesia. Unfortunately, only about 70% of patients with schizophrenia respond to conventional antipsychotic drugs. For these patients, atypical antipsychotic drugs are available. Atypical antipsychotic drugs generally are able to alleviate positive symptoms of psychosis while also improving negative symptoms of the psychosis to a greater degree than conventional antipsychotics. These drugs may improve neurocognitive deficits. Extrapyramidal (motor) side effects are not as likely to occur with the atypical antipsychotic drugs, and thus, these atypical antipsychotic drags have a lower risk of producing tardive dyskinesia. Finally these atypical antipsychotic drugs cause little or no elevation of prolactin. Unfortunately, these drags are not free of side effects. Although these drugs each produce different side effects, as a group the side effects include: agranulocytosis; increased risk of seizures, weight gain, somnolence, dizziness, tachycardia, decreased ejaculatory volume, and mild prolongation of QTc interval. Finally, the compounds of the present invention may be used in combination therapy with typical and atypical anti-psychotic drugs. All compounds within the present invention are useful for and may also be used in combination with each other to prepare pharmaceutical compositions. Such combination therapy lowers the effective dose of the anti-psychotic drug and thereby reduces the side effects of the anti-psychotic drugs. Some typical anti-psychotic drugs that may be used in the practice of the invention include Haldol. Some atypical anti-psychotic drugs include Ziprasidone, Olanzapine, Resperidone, and Quetiapine. Compounds of Formula I can be prepared as shown in Scheme 1. The key step in the preparation of this class of compounds is the coupling of commercially available 3-aminoquinuclidine (R = H) with the requisite acid chloride (Lv = CI), mixed anhydride (e.g., Lv = diphenyl phosphoryl or acyloxy of the general formula of -O-C(O)-R v where R Lv includes phenyl or t-butyl), ester (Lv = OMe or OEt), or carboxylic acid (Lv = OH) in the presence of an activating reagent. Suitable activating reagents are well known in the art, for examples see Kiso, Y.; Yajima, H. "Peptides" pp. 39-91, San Diego, CA, Academic Press, (1995), and include, but are not limited to, agents such as a carbodiimides, phosphonium and uronium salts (such as uronium salt HATU). Scheme 1 One of ordinary skill in the art will recognize that the methods described for the reaction of the unsubstituted 3-aminoquinuclidine (R 2 =H) are equally applicable to substituted compounds (R 2 ≠ H). Such compounds can be prepared by reduction of the oxime of the corresponding 3-quinuclidinone (see J. Labelled Compds. Radiopharm., 53-60 (1995) and J. Med. Chem. 988-995, (1998)). The oximes can be prepared by treatment of the 3-quinuclidinones with hydroxylamine hydrochloride in the presence of a base. The 3-quinuclidinones, where R 2 = substituted alkyl, cycloalkyl, substituted benzyl, can be prepared by known procedures (see Tet. Lett. 1015-1018, (1972), J. Am. Chem. Soc. 1278-1291 (1994), J. Am. Chem. Soc. 4548- 4552 (1989), Tetrahedron, 1139-1146 (2000)). The 3-quinuclidinones, where R 2 = aryl, can be prepared by palladium catalyzed arylation as described in J. Am. Chem. Soc. 1473-1478 (1999) and J Am. Chem. Soc. 1360-1370 (2000). Preferably, when W is a thiophene or in some furan cases, the acid is converted into a mixed anhydride by treatment with diphenylchlorophosphate in the presence of TEA and CH 2 C1 2 as the solvent. The resulting anhydride solution is directly reacted with aminoquinuclidine using aqueous DMF as the solvent. When W is furan, oxazole, oxadiazole, pyrrole, 5-thiazole, thiophene, or triazole, the acid is activated with a uronium salt, preferably HATU (see J. Am. Chem. Soc., 4397 (1993)), in the presence of a base such as DIEA in DMF, and reacted directly with aminoquinuclidine to afford the desired amides. In the case where W is a 2-thiazole, 2-oxazole, or a thiadiazole, the amide bond is formed by the reaction of the amine and ester (Lv = OEt) in an alcoholic solvent (see Liebigs Ann. Chem., 1216-1231 (1980)). It will be apparent to those skilled in the art that the requisite carboxylic acids can be obtained commercially or can be synthesized by known procedures. The thiophene acids required in Examples 1-11, 13, and 41-42 can be synthesized from the corresponding aldehydes by oxidation with NaClO 2 as described in J. Chem. Soc. Perkin Trans. I., 789-794 (1999). The requisite aldehydes can be made as described in J. Med. Chem., 1585-1599 (1997). An aryl boronic acid is reacted with a bromothiophene in the presence of a palladium (0) source, such as tetrakis- (triphenylphosphine)palladium (0), and a base, preferably aqueous sodium carbonate. The reaction works best if heated at reflux in THF/water for 24 hours. The thiophene acids of Examples 14-19 are prepared by similar methods as in Example 1 with modifications as described herein. The furan and thiophene acids required for Examples 20-30 are available commercially. Scheme 2 The thiophene acids for Examples 31-40 are synthesized from the corresponding esters by base catalyzed hydrolysis. Typical hydrolysis procedures are well known in the art. Preferably, the thiophene ester is treated with aqueous lithium hydroxide in a solvent such as dioxane. The esters are either commercially available or synthesized by reaction of a bromothiophene ester with the appropriate thiophenol or phenol as described in Coll. Czech. Chem. Comm., 2360-2363 (1980). Namely, the sodium salt of the thiophenol or phenol is formed by treatment with a strong base like sodium hydride. The sodium salt is then reacted with a bromothiophene in a solvent such as acetone. When W is thiazole, the required acids for Examples 44-49 are prepared by nucleophilic addition of the requisite phenol or thiophenol to 2-bromo-l,3-thiazole-5- carboxylic ethyl ester according to the procedure described in Helv. Chim. Ada., 2002-2022 (1997). Preferably, in EtOH utilizing K 2 CO 3 as a base (Scheme 3). The esters are hydiolyzed to the corresponding acids by procedures well known in the art. The 2-bromo-l,3-thiazole is prepared by the method described in Roczniki Chemii Ann. Soc. Chim. Polonorum, 1647-1658 (1972). The aryl 1,3-thiazole for Example 50 is prepared according to the procedure of Huntress and Pfister in J. Am. Chem. Soc, 2167-2169 (1943). The requisite l,3-thiazoles-5-acids for Examples 51 and 58-62 are commercially available. The l,3-thiazole-5-acids required in Examples 52-57 can be synthesized from the corresponding esters by base hydrolysis via procedures well known in the art. The requisite esters can be prepared by a Suzuki reaction as described in J. Med. Chem., 4985-92 (1995). An aryl boronic acid is reacted with a bromothiazole ester in the presence of a palladium (0) source, such as tetrakis- (triphenylphosphine)palladium (0), and a base, preferably aqueous sodium carbonate. The 1,3,4-thiadiazole esters for Examples 64-72 are synthesized by nucleophilic addition of the requisite phenol or thiophenol to 2-bromo-l,3,4-thiadiazolezole-5- carboxylic ethyl ester as described in Can. J. Chem., 243-250 (1977) (Scheme 3). Scheme 3 The triazole for Example 75 and the oxadiazole for Example 76 are prepared by the methods of McKillop et al., Tetrahedron Lett. 23, 3357-3360 (1982) with modifications as described herein. The oxadiazole for Example 77 is prepared following the procedures of Snyder in J. Org. Chem. 3257-3269 (1990), Muchowski in Can. J. Chem. 3079-3082 (1972), and Crenshaw in US 4,001,238. The 5-substituted-l,3-oxazole-2-esters for Examples 79-88 are synthesized according to procedures described in J. Pharm. Soc. Japan, 305-7 (1956) as shown in Scheme 4. The 5-substituted-l,3-thiazole-2-esters for Examples 89-102 are synthesized according to procedures described in Chem. Pharm. Bull., 4195-4198 (1982). Scheme 4 The furans for Examples 103-130 are commercially available or can be prepared from their corresponding aldehydes or esters as described for the thiophenes (Examples 1-11). hi the event that the furan is not commercially available, it can be prepared by the method of Bussolari and Rehborn described in Org. Lett. 965-7 ( 1999). Furan Examples 131 - 146 are prepared in a convergent means by a direct palladium catalyzed Suzuki coupling N-[(3R)-l-azabicyclo[2.2.2]oct-3-yl]-5-bromo- furan-2-carboxamide with the requisite boronic acid by the method described in Org. Lett. 965-7 (1999), to yield directly the desired aryl amides (Scheme 5). Scheme 5 One of ordinary skill in the art would recognize that Examples 12, and 147- 149 are prepared by reduction of the corresponding aryl nitro compounds by methods well known in the art, preferably by reduction with Pd/C in an alcoholic solvent such as EtOH under H 2 . The acid for example 150 is prepared by a Pd(0) catalyzed Sonogashira coupling of 5-bromo-2-furanal and phenyl acetylene as described in Tetrathedron Lett., 4467-70 (1975). The resulting aldehyde is converted to the desired analog by methods as described for Example 103. Example 151 is prepared by addition of the sodium salt of phenol to N-[(3R)-l-azabicyclo[2.2.2]oct-3-yl]-5- bromo-furan-2-carboxamide. The requisite acid for Example 152 is prepared by bromination of methyl-5-bromo- 1 -methyl- 1 H-pyrrole-2-carboxylate, followed by similar Pd-catalyzed coupling as described for Example 1. The l,3-oxazole-2-carboxylic acid required for Example 153 is prepared by the method described in J. Pharm. Sci. Japan 305-7, (1956). 3-Phenyl- 1,2,4- oxadiazole-5-carboxylic acid required for Example 154 is prepared by the method of Wurm as described in Chem. Ber., 3133, (1889). The 2-phenyl-l,3-oxazole-5- carboxylic acid required for Example 155 is prepared by the method described in Chem. Heterocycl. Compd. (Engl.Transl.), 654-663, (1986). 2-Phenyl-l,3-oxazole-4- carboxylic acid required for Example 156 is prepared as described by Korte and Stoeriko, in Chem. Ber., 1033-1042, (1960). The 5-phenylisoxazole-3-carboxylic acid for Example 157 is prepared by the method of Vaughan and Spencer as described in J. Org. Chem. 1160-4, (1960). Thioamides, such as Example 159, can be prepared from the requisite thioester by direct displacement of the thioester with aminoquinuclidine (Scheme 6). The thioester can be prepared as described in J. Organometallic Chem., 95-98 (1987). One of ordinary skill in the art would quickly identify that compounds such as Example 159 could also be prepared directly from the amides exemplified throughout this patent by direct treatment with a reagent such and Lawesson's reagent (see Lawesson et. al. in Bull. Soc. Chim. Belg., 229 (1978)) or P 4 Sι 0 (see Chem. Rev., 45 (1961)). Scheme 6 The following examples are provided as examples and are not intended to limit the scope of this invention to only those provided examples and named compounds. Also, the salts made in the examples are only exemplary and are not intended to limit the invention. Any pharmaceutically acceptable salt can be made by one of ordinary skill in the art. Further, the naming of specific stereoisomers is for exemplification, and is not intended to limit in anyway the scope of the invention. The invention includes the following examples in pure stereoisomeric form or as racemic mixtures.

Materials and Methods for identifying binding constants: Membrane Preparation. Male Sprague-Dawley rats (300-350g) are sacrificed by decapitation and the brains (whole brain minus cerebellum) are dissected quickly, weighed and homogenized in 9 volumes/g wet weight of ice-cold 0.32 M sucrose using a rotating pestle on setting 50 (10 up and down strokes). The homogenate is centrifuged at 1,000 x g for 10 minutes at 4 °C. The supernatant is collected and centrifuged at 20,000 x g for 20 minutes at 4 °C. The resulting pellet is resuspended to a protein concentration of 1 - 8 mg/mL. Aliquots of 5 mL homogenate are frozen at -80 °C until needed for the assay. On the day of the assay, aliquots are thawed at room temperature and diluted with Kreb's - 20 mM Hepes buffer pH 7.0 (at room temperature) containing 4.16 mM NaHCO 3 , 0.44 mM KH 2 PO 4 , 127 mM NaCI, 5.36 mM KCl, 1.26 mM CaCl 2 , and 0.98 mM MgCl , so that 25 - 150 μg protein are added per test tube. Proteins are determined by the Bradford method (Bradford, M.M., Anal. Biochem., 72, 248-254, 1976) using bovine serum albumin as the standard. Binding Assay. For saturation studies, 0.4 mL homogenate are added to test tubes containing buffer and various concentrations of radioligand, and are incubated in a final volume of 0.5 mL for 1 hour at 25 °C. Nonspecific binding was determined in tissues incubated in parallel in the presence of 0.05 ml MLA for a final concentration of 1 μM MLA, added before the radioligand. hi competition studies, drugs are added in increasing concentrations to the test tubes before addition of 0.05 ml [ 3 H]-MLA for a final concentration of 3.0 to 4.0 nM [ 3 H]-MLA. The incubations are terminated by rapid vacuum filtration through Whatman GF/B glass filter paper mounted on a 48 well Brandel cell harvester. Filters are pre-soaked in 50 mM Tris HCI pH 7.0 - 0.05 % polyethylenimine. The filters are rapidly washed two times with 5 mL aliquots of cold 0.9% saline and then counted for radioactivity by liquid scintillation spectrometry. Data Analysis. In competition binding studies, the inhibition constant (Ki) was calculated from the concentration dependent inhibition of [ 3 H]-MLA binding obtained from non-linear regression fitting program according to the Cheng-Prusoff equation (Cheng, Y.C. and Prussoff, W.H., Biochem. Pharmacol, 22, p. 3099-3108, 1973). Hill coefficients were obtained using non-linear regression (GraphPad Prism sigmoidal dose-response with variable slope). The aforementioned examples have the provided Ki values: 30 20 25
