Description: FUSED PYRROLECARBOXAMIDES : GABA BRAIN RECEPTOR IGANDS BACKGROUND OF THE INVENTION Field of the Invention This invention relates to fused pyrrolecarboxamides . This invention also relates to pharmaceutical compositions comprising such compounds and to the use of such compounds in treatment of certain central nervous system (CNS) diseases. This invention also relates to the use of these fused pyrrolecarboxamide compounds in combination with one or more other CNS agents to potentiate the effects of the other CNS agents. Additionally this invention relates to the use such compounds as probes for the localization of GABA A receptors in tissue sections. Description of the related art The GABA A receptor superfamily represents one of the classes of receptors through which the major inhibitory neurotransmitter, γ-aminobutyric acid, or GABA, acts. Widely, although unequally, distributed through the mammalian brain, GABA mediates many of its actions through a complex of proteins called the GABA A receptor, which causes alteration in chloride conductance and membrane polarization. A number of cDNAs for GABA A receptor subunits have been characterized. To date at least 6α, 3β, 3γ, lε, lδ and 2p subunits have been identified. It is generally accepted that native GABA A receptors are typically composed of 2α, 2β, and lγ subunits (Pritchett & Seeburg Science 1989; 245:1389-1392 and Knight et . al . , Recept . Channels 1998; 6:1-18) . Evidence such as message distribution, genome localization and biochemical study results suggest that the major naturally occurring receptor combinations are αιβ 2 γ2, oc 3 β 3 γ 2 , and α 5 β 3 γ (Mohler et. al.Neuroch. Res. 1995; 20(5): 631 - 636). Benzodiazepines exert their pharmacological actions by interacting with the benzodiazepine binding sites associated with the GABA A receptor. In addition to the benzodiazepine site, the GABA A receptor contains sites of interaction for several other classes of drugs. These include a steroid binding site, a picrotoxin site, and the barbiturate site. The benzodiazepine site of the GABA A receptor is a distinct site on the receptor complex that does not overlap with the site of interaction for GABA or for other classes of drugs that bind to the receptor (see, e.g., Cooper, et al . , The Biochemical Basis of Neuropharmacology, 6 th ed. , 1991, pp. 145-148, Oxford University Press, New York) . Early electrophysiological studies indicated that a major action of the benzodiazepines was enhancement of GABAergic inhibition. Compounds that selectively bind to the benzodiazepine site and enhance the ability of GABA to open GABA A receptor channels are agonists of GABA receptors. Other compounds that interact with the same site but negatively modulate the action of GABA are called inverse agonists. Compounds belonging to a third class bind selectively to the benzodiazepine site and yet have little or no effect on GABA activity, but can block the action of GABA A receptor agonists or inverse agonists that act at this site. These compounds are referred to as antagonists. The important allosteric modulatory effects of drugs acting at the benzodiazepine site were recognized early and the distribution of activities at different receptor subtypes has been an area of intense pharmacological discovery. Agonists that act at the benzodiazepine site are known to exhibit anxiolytic, sedative, and hypnotic effects, while compounds that act as inverse agonists at this site elicit anxiogenic, cognition enhancing, and proconvulsant effects. While benzodiazepines have a long history of pharmaceutical use as anxiolytics, these compounds often exhibit a number of unwanted side effects. These may include cognitive impairment, sedation, ataxia, potentiation of ethanol effects, and a tendency for tolerance and drug dependence. GABA A selective ligands may also act to potentiate the effects of certain other CNS active compounds. For example, there is evidence that selective serotonin reuptake inhibitors (SSRIs) may show greater antidepressant activity when used in combination with GABA A selective ligands than when used alone. Various compounds have been prepared as benzodiazepine agonists and antagonists. For Example, U.S. Patents Nos. 3,455,943, 4,435,403, 4,596,808, 4,623,649, and 4,719,210, German Patent No. DE 3,246,932, and Liebigs Ann. Chem. 1986, 1749 teach assorted benzodiazepine agonists and antagonists and related anti -depressant and central nervous system active compounds .

Other references, such as U.S. Patent No. 4,435,403 and German patent DE 3,246,932 disclose pyrimidino [5, 4-b] indoles and beta-carboline derivatives. A variety of indole-3 -carboxamides is described in the literature. See, for example, J. Org. Chem., 42: 1883-1885 (1977); J. Heterocylic Chem., 14: 519-520 (1977).

Assays may be used to predict these desirable pharmacological properties. Assays used to predict bioavailability include transport across human intestinal cell monolayers, including Caco-2 cell monolayers. Toxicity to cultured hepatocyctes may be used to predict compound toxicity. Penetration of the blood brain barrier of a compound in humans may be predicted from the brain levels of the compound in laboratory animals given the compound intravenously. Serum protein binding may be predicted from albumin binding assays. Such assays are described in a review by Oravcova, et al . (Journal of Chromatography B (1996) volume 677, pages 1-27) . Compound half-life is inversely proportional to the frequency of dosage of a compound. In vi tro half-lifes of compounds may be predicted from assays of microsomal half-life as described by Kuhnz and Gieschen (Drug Metabolism and Disposition, (1998) volume 26, pages 1120-1127) .

Example 7 Receptor autoradiography Receptor autoradiography (receptor mapping) is carried out in vitro as described by Kuhar in sections 8.1.1 to 8.1.9 of Current Protocols in Pharmacology (1998) John Wiley & Sons, New York, using radiolabeled compounds of the invention prepared as described in the preceding Example. Example 8 Binding Assay This assay is a standard assay for GABA A binding affinity. The high affinity and high selectivity of compounds of this invention for the benzodiazepine site of the GABA A receptor is confirmed using the binding assay described in Thomas and Tallman (J. Bio . Chem. 1981; 156:9838-9842, and J. Neurosci . 1983; 3 :433-440) . Rat cortical tissue is dissected and homogenized in 25 volumes (w/v) of Buffer A (0.05 M Tris HCl buffer, pH 7.4 at 4 °C) . The tissue homogenate is centrifuged in the cold (4 °C) at 20,000 x g for 20 minutes. The supernatant is decanted, the pellet rehomogenized in the same volume of buffer, and centrifuged again at 20,000 x g. The supernatant of this centrifugation step is decanted and the pellet stored at -20 C overnight. The pellet is then thawed and resuspended in 25 volumes of Buffer A (original wt/vol), centrifuged at 20,000 x g and the supernatant decanted. This wash step is repeated once. The pellet is finally resuspended in 50 volumes of Buffer A. Incubations containing 100 μl of tissue homogenate, 100 μl of radioligand, (0.5 nM 3 H-Rol5-1788 [ 3 H-Flumazenil] , specific activity 80 Ci/mmol) , and test compound or control (see below) , and are brought to a total volume of 500 μl with Buffer A. Incubations are carried for 30 min at 4°C and then rapidly filtered through Whatman GFB filters to separate free and bound ligand. Filters are washed twice with fresh Buffer A and counted in a liquid scintillation counter. Nonspecific binding (control) is determined by displacement of 3 H Rol5-1788 with 10 μM Diazepam (Research Biochemicals International, Natick, MA) . Data were collected in triplicate, averaged, and percent inhibition of total specific binding (Total Specific Binding = Total - Nonspecific) was calculated for each compound. A competition binding curve is obtained with up to 11 points spanning the compound concentration range from 10 "12 M to 10 "5 M obtained per curve by the method described above for determining percent inhibition. Ki values are calculated according the Cheng-Prussof equation. When tested in this assay preferred compounds of the invention exihibit Ki values of less than 1 uM, more preferred compounds of the invention have Ki values of less than 500 nM, still more preferred compounds of the invention have Ki values of less than 100 nM, and even more preferred compounds have Ki values of less than 10 nM. Results for several compounds of this invention are listed in Table V. Example 9 Electrophysiology The following assay is used to determine if a compound of the invention act as an agonist, an antagonist, or an inverse agonist at the benzodiazepine site of the GABA A receptor. Assays are carried out as described in White and Gurley (NeuroReport 6: 1313-1316, 1995) and White, Gurley, Hartnett, Stirling, and Gregory (Receptors and Channels 3 . : 1-5, 1995) with modifications. Electrophysiological recordings are carried out using the two electrode voltage-clamp technique at a membrane holding potential of -70 mV. Xenopus Laevis oocytes are enzymatically isolated and injected with non-polyadenylated cRNA mixed in a ratio of 4:1:4 for α, β and γ subunits, respectively. Of the nine combinations of α, β and γ subunits described in the White et al . publications, preferred combinations are αχβ 2 γ2, <2β 3 Y2, ot 3 β 3 γ 2 , and α 5 β 3 γ 2 . Preferably all of the subunit cRNAs in each combination are human clones or all are rat clones. The sequence of each of these cloned subunits is available from GENBANK, e.g., human αi, GENBANK accession no. X14766, human α 2 , GENBANK accession no. A28100; human α 3 , GENBANK accession no. A28102; human α 5 , GENBANK accession no. A28104; human β 2 , GENBANK accession no. M82919; human β 3 , GENBANK accession no. Z20136; human β 2 , GENBANK accession no. X15376; rat α-i, GENBANK accession no. L08490, rat α 2 , GENBANK accession no. L08491; rat α 3 , GENBANK accession no. L08492; rat α 5 , GENBANK accession no. L08494; rat β 2 , GENBANK accession no. X15467; rat β 3 , GENBANK accession no. X15468; and rat γ 2 , GENBANK accession no. L08497. For each subunit combination, sufficient message for each constituent subunit is injected to provide current amplitudes of >10 nA when 1 μM GABA is applied. Compounds are evaluated against a GABA concentration that evokes <10% of the maximal evokable GABA current (e.g. 1 μM - 9 μM) . Each oocyte is exposed to increasing concentrations of compound in order to evaluate a concentration/effect relationship. Compound efficacy is calculated as a percent- change in current amplitude: 100* ( (Ic/I) -1) , where Ic is the GABA evoked current amplitude observed in the presence of test compound and I is the GABA evoked current amplitude observed in the absence of the test compound. Specificity of a compound for the benzodiazepine site is determined following completion of a concentration/effect curve. After washing the oocyte sufficiently to remove previously applied compound, the oocyte is exposed to GABA + 1 μM R015-1788, followed by exposure to GABA + 1 μM R015-1788 + test compound. Percent change due to addition of compound is calculated as described above. Any percent change observed in the presence of R015-1788 is subtracted from the percent changes in current amplitude observed in the absence of 1 μM R015-1788. These net values are used for the calculation of average efficacy and EC 50 values by standard methods. To evaluate average efficacy and EC 50 values, the concentration/effect data are averaged across cells and fit to the logistic equation.
