Patent ID: RE40703

Claim:
A compound benzamide compound represented by formula (1): wherein A is an optionally substituted phenyl group or an optionally substituted heterocyclic group wherein the heterocycle part in the optionally substituted heterocyclic group is selected from the group consisting of pyridine, pyrazine, pyridazine, thiophene and furan, and wherein the substituent(s) for the phenyl group or the heterocyclic group is (are) 1 to 4 substituents selected from the group consisting of a halogen atom, a hydroxyl group, an amino group, a nitro group, a cyano group, an alkyl group having 1 to 4 carbons, an alkoxy group having 1 to 4 carbons, an aminoalkyl group having 1 to 4 carbons, an alkylamino group having 1 to 4 carbons, an acyl group having 1 to 4 carbons, an acylamino group having 1 to 4 carbons, an alkylthio group having 1 to 4 carbons, and a perfluoroalkyl group having 1 to 4 carbons , a perfluoroalkyloxy group having 1 to 4 carbons, a carboxyl group, an alkoxycarbonyl group having 1 to 4 carbons, a phenyl group and a heterocyclic group ; X is a bond or a moiety having a structure selected from those illustrated in formula (2): wherein e is an integer of 1 to 4; g and m are independently an integer of 0 to 4; R 4 is a hydrogen atom or an optionally substituted alkyl group having 1 to 4 carbons, or the acyl group represented by formula (3) wherein R 6 is an optionally substituted alkyl group having 1 to 4 carbons, a perfluoroalkyl group having 1 to 4 carbons, a phenyl group or a heterocyclic group; pyridyl group; R 5 is a hydrogen atom or an optionally substituted alkyl group having 1 to 4 carbons ; n is an integer of 0 to 4, provided that when X is a bond, n is not zero ; Q is a moiety having a structure selected from those illustrated in formula (4) wherein R 7 and R 8 are independently is a hydrogen atom or an optionally substituted alkyl group having 1 to 4 carbons; R 1 and R 2 are independently a hydrogen atom, a halogen atom , a hydroxyl group, an amino group, or an alkyl group having 1 to 4 carbons , an alkoxy group having 1 to 4 carbons, an aminoalkyl group having 1 to 4 carbons, an alkylamino group having 1 to 4 carbons, an acyl group having 1 to 4 carbons, an acylamino group having 1 to 4 carbons, an alkylthio group having 1 to 4 carbons, a perfluoroalkyl group having 1 to 4 carbons, a perfluoroalkyloxy group having 1 to 4 carbons, a carboxyl group or an alkoxycarbonyl group having 1 to 4 carbons ; R 3 is a hydroxyl or an amino group or a pharmaceutically acceptable salt thereof.
