Fused heterocyclic compounds (I) are new. Fused heterocyclic compounds of formula (I) and their salts and hydrates are new. [Image] A, B, D, E, G : N, O, S, (CR 1R 2) m, CO, CS, NR 3, SO or SO 2; R 1, R 2H, Alk, 2-6C alkenyl, 2-6C alkynyl, CycOAlk, AlkOAlk, AlkCyc or 1-6C alkyl-aryl, or CR 1R 23-8 membered ring or is replaced by CR 2=CR 2 or N=CR 2; m : 0-4; Alk : 1-6C alkyl; Cyc : 3-8C cycloalkyl; R 3H, COR 4, S(O) nR 5, Alk 2, optionally substituted aryl or optionally benzene fused Cyc (optionally substituted by 1-4C alkyl); Alk 21-10C alkyl, 2-10C alkenyl or 2-10C alkynyl (all optionally substituted by Q); R 4, R 5Alk or Ar; n : 0-2; J : N, CJ 1, NJ 1 or CJ 1J 1; J 1H, amino, CN, Alk, 1-6C haloalkyl, SO 2NHAlk, aryl or optionally substituted, optionally unsaturated heterocyclyl; K, L : C or N; M : H, halo, CN, Alk 3, NR 11R 12, OR 13, S(O) qR 14, or optionally substituted 2-10C alkenyl, 2-10C alkynyl, aryl or heteroaryl; Alk 3Alk, OAlk or SAlk (all optionally substituted by 1 or more Q); Q : halo, OH, NO 2, CN, COOH, COOAlk, S(O) rR 15, NR 18R 19, Alk, OAlk, Cyc (optionally substituted by 1-4C alkyl), 1-4C alkoxy-1-6C alkyl, 3-8 membered saturated heterocyclyl (optionally substituted by 1-4C alkyl), or optionally substituted aryl or heteroaryl; R 11, R 12H, Alk (optionally substituted by Q), 1-4C alkylacyl or Ar; Ar : optionally substituted aryl-1-4C alkyl, heteroaryl-1-4C alkyl, aryl or heteroaryl; R 13H, Q, 1-4C alkylacyl or Ar; R 14Alk or Ar; q : 0-2; R 15, R 16H Alk (optionally substituted by optionally substituted aryl), 1-4C alkylacyl or Ar; R 18, R 19H, Alk or 1-4C alkylacyl; provided that: (i) KEGJL form a 5 or 6 membered optionally unsaturated ring; and (ii) when K and L = N or K = N, L = C, A, B = CH2 then J is not amino, CN, optionally substituted aminosulfonyl or C(1H-tetrazol-5-yl). ACTIVITY : Antidepressant; tranquilizer; antiinflammatory; hypotensive; gastrointestinal; antiulcer; antiemetic; nootropic; neuroprotective; anabolic; anorectic; antidiabetic; CNS; anticonvulsant; antialcoholic; analgesic; cerebroprotective; auditory; endocrine; vasotropic; cytostatic; anti-HIV; hemostatic; osteopathic; antithyroid; antiasthmatic.
