FIELD: medicine, pharmaceutics. ^ SUBSTANCE: present invention refers to aryl-isoxazole-4-yl-imidazole derivatives of formula I and to their pharmaceutically acceptable acid addition salts. The compounds of the present invention exhibit GABA A 5 receptor binding site activity and selectivity. In general formula I ^ each of R1-R3 independently represents hydrogen atom or halogen atom; R4 represents hydrogen atom, lower alkyl, C3-C7cycloalkyl, -(CH2)n-O-lower alkyl or hydroxy substituted lowest alkyl; R5 represents -(CH2)m-phenyl or -(CH2)m-(5-6-members heteroaryl with 1-2 heteroatoms independently seected from N, O) which optionally substituted by one or more substitutes selected from a group consisting of halogen atom, cyano, nitro, lower alkyl, lower alkoxy, lower alkylsulphanyl, lower alkyl substituted by halogen atom, -C(O)-lower alkyl, -C(O)-O-lower alkyl, -NH-C(O)-O-lower alkyl or -C(O)-NH-R' where R' represents the lower alkynyl or hydroxy substituted lower alkyl, or represents -(CH2)n-C3-C7-cycloalkyl, -(CH2)n-(6-members heterocyclyl with 1-2 heteroatoms selected from N, O), -(CH2)n-(5-6-members heteroaryl with 1-2 heteroatoms selected from N, O) or -(CH2)n-phenyl optionally substituted by halogen atom; R6 represents hydrogen atom, -C(O)H, -(CH2)n-O-lower alkyl, -C(O)O-lower alkyl, lower alkyl substituted by hydroxy or halogen atom, or represents C3-C7-cycloalkyl, phenyl, or represents -(CH2)n-O-CH2-phenyl optionally substituted by halogen atom or lower alkyl, or represents -(CH2)n-O-CH2-(6-members heteroaryl with 1 heteroatom selected from N) optionally substituted by lower alkyl or lower alkyl substituted by halogen atoms, or represents -(CH2)n-NH-(CH2)o-(6-members heterocyclyl with 2 heteroatoms selected from N; n means 0, 1, 2 or 3; m means 0 or 1; o means 1, 2 or 3. ^ EFFECT: presented preparation of a drug containing one or more compound of formula I and application of the compounds for preparing the drug. ^ 31 cl, 168 ex |
