Description

INDONES, 1H-INDAZQLES, 1, 2-BENZYSOXAZQLES, AND 1,2- BENCISQTIAZQLES, AND PREPARATION AND USE OF THEMSELVES FIELD OF THE INVENTION 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 acetylcholine, nicotinic, defective or malfunctioning receptors. , especially of the brain. ' In addition, this information refers to new compounds, for example, Índoles, IH-indazoles, 1,2-bencisoxazoles, and 1,2-biscisothiazoles, which act as ligands for the nAChR subtype, methods for preparing these compounds, compositions comprising these compounds, and methods of using them.
BACKGROUND OF THE INVENTION There are two types of receptors for the neurotransmitter acetylcholine: muscarinic receptors and nicotinic receptors, based on the selectivity of action of the drug nicotine and nicotine, respectively. Muscarinic receptors are G-protein coupled receptors. Nicotinic receptors are members of the family of ion channels controlled by ligands. When activated, the conductance of the ions is increased through the nicotinic ion channels. The nicotinic alpha-7 receptor protein forms a homo-pentameric channel in vitro that is highly permeable to a variety of cations (eg, Ca ++). Each nicotinic alpha-7 receptor has four transmembrane domains, called Ml, M2, M3, and M4. The M2 domain has been suggested to form the wall that forms the channel. The sequence alignment shows that nicotinic alpha-7 is highly conserved during evolution. The M2 domain that was from the channel is identical in chicken-to-human protein sequence. For analysis of the alpha-7 receptor see, for example Revah et al. (1991), Nature, 353, 846-849; Galci et al-. (1992), Nature 359, 500-505; Fucile et al. (2000), PNAS 91. { tí), 3643-3648; Briggs et al. (1999), Eur. I Pharmacol. 366 (2-3), 301-308; and Gopala rishnan et al. (1995), Eur. J Pharmacol. 290 (3), 237-246. The nicotinic alpha-7 receptor channel is expressed in several brain regions and is believed to be involved in many important biological processes in the central nervous system (C? S), including learning and memory. The nicotinic alpha-7 receptors are located in both presynaptic and post-synaptic terminals and it has been suggested that they are included in the modulation of synaptic transmission. Therefore, it is of interest to develop new compounds, which act as ligands for the nAChR subtype a7, for the treatment of disease conditions associated with acetylcholine, nicotinic, defective or malfunctioning receptors.

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 for stimulating or activating the inhibition of nicotinic alpha-7 receptors, for example, as determined by a conventional assay or one described herein, either in vitro or in vivo (in an animal, for example, in a model of animal, or in a mammal or a human); a method for treating a neurological syndrome, eg, memory loss, especially long-term memory, cognitive impairment or decline, memory impairment, etc., a method of treating a disease state modulated by alpha-7 nicotinic activity, in a mammal, for example, a human, for example, those mentioned herein. The compounds of the present invention can be prepared in conventional manner. Some of the known processes can be used as described below. All starting materials are known or can be prepared in a conventional manner from known starting materials. The synthesis of similar compounds is described in copending application serial number 10 / 669,645 filed on September 25, 2003, the full description of which is incorporated herein by reference. The acids that can be used in the preparation of the bicyclobase amide are commercially available, they can be prepared by known procedures, described in the literature, or as described below. For example, indazole-3-carboxylic acid is commercially available. Bromoindazole acids can be prepared from the corresponding isatins by basic hydrolysis, diazotization and reduction [Snyder, H.R.; et al. J. Am. Chem. Soc. 1952, 74, 2009]. Benzisoxazole-3-carboxylic acid can be prepared from 2,5-dibromonitrobenzene by reaction with diethylmalonate, saponification with decarboxylation, followed by pro-esterification, reaction with isoamyl nitrite under basic conditions, hydrogenolysis, and saponification [Angelí, R.M.; Baldwin, I.R .; Bamborough, P .; Deboeck, N.M .; Longstaff, T.; Swanson, S. WO04010995A1]. The 3-benzisothiazole carboxylic acid can be prepared from thiophene-nol by reaction with oxalyl chloride and aluminum chloride followed by treatment with hydroxylamine, hydrogen peroxide, and sodium hydroxide. The bicycloamines that can be used in the preparation of bicyclobase amides are commercially available, can be prepared by known procedures described in the literature, or as described below. For example, the hydrochloride of (SS, 4S) -2-tert-butyloxycarbonyl-2,5-diazabicyclo [2.2.1] heptane is commercially available. (LS, 4S) -2-Methyl-2, 5-diazabicyclo [2.2.1] heptane can be prepared by the reduction of tert-butyl carbamate with lithium aluminum hydride or by the reductive amination sequence followed by deprotection. 2,5-Diazabicyclo [2.2.2] octane can be prepared as described in the literature (Newman, H. Heterocyclic Chem. 1974, 12, 449. Sturm, P.A.; Henry, D.W. Med. Chem. 1974, 17, 481). 2-Methyl-2, 5-diazabicyclo [2.2.2] octane can be prepared from diethyl 2,5-diaminohexanedioate by cyclization of the N-benzyl intermediate, reduction of tertiary amides, hydrogenolysis, selective protection, amination reductive and deprotection. The bicyclobase amide can be prepared by the coupling reaction of acids with bicycloamine and HBTU or HOBt and EDCI in DMF, or by converting the acids to the corresponding acid chloride and then reaction with bicycloamine (Macor, JE; Gurley, D.; Lanthorn, T .; Loch, J.; Mack, RA; Mullen, G.; Tran, O .; Wright, N.; and JE Macor, JE Bioorg, Med. Chem. Lett., 2001, 9,319.). The couplings are generally carried out at ambient temperatures for 4-8 hours. Thioamide analogs can be prepared from the amides by reaction with Lawesson's reagent (Wipf P .; Kim, Y .; Goldstein, D.M., Am. Chem. Soc., 1995, 117, 11106). Bicyclobase methyleneamine analogs can be prepared from bicyclobase amides by normal reduction methods as described, for example, below. The resulting adducts can be isolated and encoded by standard techniques, such as chromatography or recrystallization, practiced by one skilled in the art. One skilled in the art will recognize that the compounds of Formulas II-III can exist in different geometric isomeric and tautomeric forms. All those compounds, including cis isomers, trans isomers, diastereomeric mixtures, racemates, non-racemic mixtures of enantiomers, substantially pure, and pure enantiomers are within the scope of the present invention. The substantially pure enantiomers contain not more than 5% w / w of the corresponding opposite enantiomer, preferably not more than 2%, more preferably not 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 diastereomeric salts using an optically active acid or base, or formation of covalent diastereomers. Examples of suitable acids are tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, ditoluoyltartaric acid, and camphorsulfonic acid. Mixtures of diastereomers 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 released from the separated diastereomeric salts. , A different process for the separation of optical isomers comprises the use of chiral chromatography (for example, chiral HPLC columns), with or without conventional derivatization, optionally chosen to maximize the separation of the enantiomers.

As agonists for nAChRs a-7, 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 that form a central ion-conducting pore.There are currently eleven known neuronal subunits of nAChR (a2 - a9 and ß2 - ß4) There are also five additional subunits expressed in the peripheral nervous system (al, ßl,?, d, e) .The nAChR receptor subtypes can be homopentameric or heteropentameric.The subtype that has received considerable attention is the subtype of a-7 homopentameric receptor formed of five subunits a-7. The nAChR a-7 inhibit a high affinity for nicotine (agonist) and for a-bungarotoxin (antagonist). shown that nAChR a-7 agonists may be useful in the treatment of psychotic diseases, neurodegenerative diseases, and cognitive impairment, among other things. While nicotine is a known agonist, it is a need for development of other nAChR a-7 agonists, especially selective agonists that are less toxic or that exhibit fewer side effects than nicotine. The compound anabaseine, that is, 2- (3-pyridyl) -3,4,5,6-tetrahydropyridine is a toxin that occurs naturally in certain marine worms (nemerteous worms) and ants. See, for example, Kern et al., Toxicon, 9:23, 1971. Anabaseine is a potent activator of mammalian nicotinic receptors. See, for example, Kern, Amer. Zoologist, 25, 99, 1985. Certain analogs of anabaseine such as anabasine and DMAB (3- [4- (dimethylamino) benzylidene] -3,4,5,6-tetrahydro-2 ', 3'-bipyridine) are also agonists known nicotinic receptors. See, for example, U.S. Patent No. 5,602,257 and WO 92/15306. A particular anabaseine analogue, (E-3- [2,4-dimethoxy-benzylidene] -anabaseine, also known as GTS-21 and DMXB (see, for example, United States patent number ,741,802), is a partial, selective nAChR agonist that has been studied extensively. For example, abnormal sensory inhibition is a deficit of sensory processing in schizophrenics and GTS-21 has been found to increase sensory inhibition through interaction with nAC r a-7. See, for example, Stevens et al., Psychopharmacology, 136: 320-27 (1998). Another compound known to be a nAChR a-7 selective agonist is Tropisetron, ie, H, 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 A-7 Nicotinic Agonist Partial Receptor," Bioorg. Med. Chem. Lett. 2001, 319-321).

To a solution of carboxylic acid (1 mmol) in tetrahydrofuran (10 mL) and N, N-dimethylformamide (1 mL) was added N, N-diisopropylethylamine (3 mmol) and amine dihydrochloride of bicyclobase (1 mmol). The reaction mixture was kept at room temperature for 30 minutes under nitrogen and then HATU (1.00 mmol) was added. After 18 hours, the reaction mixture was partitioned between saturated aqueous potassium carbonate solution and 95/5 dichloromethane / methanol. The aqueous layer was extracted with dichloromethane / methanol 95/5 (2X), and the combined organic layers were washed with brine, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel using the mixture of [dichloromethane / methanol / ammonium hydroxide 90/10/1] as the eluent, thereby providing the carboxamide product.
