Patent ID: 7365089

Claim:
A compound of formula (I) wherein R 1 is hydrogen atom or a straight or branched C 1-4 alkyl group; R 2 is hydrogen atom or a straight or branched C 1-4 alkyl group; R 3 is a phenyl group, thienyl group, or furyl group, wherein the phenyl group, thienyl group, or furyl group is optionally substituted by one or more straight or branched C 1-4 alkyl group, straight or branched C 1-4 alkoxy group, or halogen atom, or a 5 or 6 membered heteroaromatic ring, containing one, two or three nitrogen atoms, or a 5 membered heteroaromatic ring, containing one nitrogen atom and one oxygen atom or one nitrogen atom and one sulphur atom, wherein the 5 or 6 membered heteroaromatic ring is optionally substituted by one or more straight or branched (C 1-4 alkyl group, straight or branched C 1-4 alkoxy group, or halogen atom; R 4 and R 5 are independently from each other for hydrogen atom, or form together an 1,3-butadienyl group, optionally substituted with a methylendioxy group or one or more straight or branched C 1-4 aklyl group, straight or branched C 1-4 alkoxy group, hydroxy group or halogen atom; R 6 is hydrogen atom, a cyano group, aminocarbonyl group, C 1-4 alkoxycarbonyl group, or carboxy group; R 7 is hydrogen atom, a straight or branched C 1-4 alkyl group, a C 1-4 alkylene group, optionally substituted by a phenyl group, a phenyl group, benzyl group, thienyl group or furyl group, wherein the phenyl group, benzyl group, thienyl group, or furyl group is optionally substituted by a methylendioxy group, or one or more straight or branched C 1-4 alkyl group, straight or branched C 1-4 alkoxy group, hydroxy group, trifluoromethyl group, cyano group, halogen atom, amino, or mono- or dialkylamino group, or a 5 or 6 membered heteroaromatic ring, containing one, two or three nitrogen atoms, or a 5 membered heteroaromatic ring, containing one nitrogen atom and one oxygen atom or one nitrogen atom and one sulphur atom, wherein the 5 or 6 membered heteroaromatic ring is optionally substituted by one or more straight or branched C 1-4 alkyl group, straight or branched C 1-4 alkoxy group, or halogen atom; X is a —CH 2 — group, —NH— group, —NR 12 — group, a sulphur atom, an oxygen atom, a sulpho group or a sulphoxy group wherein R 12 is a straight or branched C 1-4 alkyl group or C 3-6 cycloalkyl group; and n stands for 0, 1 or 2; provided that when R 4 and R 5 are both hydrogen atom, R 6 is hydrogen atom or a cyano group, R 7 is hydrogen atom, a straight or branched C 1-4 alkyl group, or a phenyl group, and X is a —CH 2 — group, then R 3 (CR 1 R 2 ) n - taken together is other than hydrogen atom straight or branched C 1-4 alkyl group; or its salt, solvate or optically active isomer thereof, or a salt or solvate of the optically active isomer.
