Patent ID: 7375119

Claim:
An amide-type carboxamide derivative of the formula [1]: wherein X is a group of the formula: —N═ or the formula: —CH═; Y 1 and Y 2 are the same or different and each is a group selected from a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a lower alkyl group substituted by halogen atom, a lower alkoxycarbonyl group, a carboxyl group, a lower alkylcarbamoyl group and a phenyl group; R 1 is a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group; R 2 is a group of the formula: —CO—R 21 —R 22 ; R 21 is a lower alkylene group or a cycloalkanediyl group; and R 22 is a group of the formula: wherein R 23 and R 24 are the same or different and each is a lower alkyl group or an amino-lower alkyl group optionally substituted by a lower alkyl group; or combine together at the ends to form an optionally substituted nitrogen-containing saturated heterocyclic group along with the adjacent group: —N—C(═O)—; R 25 and R 26 are the same or different and each is a lower alkyl group or an amino-lower alkyl group optionally substituted by a lower alkyl group; or combine together at the ends to form an optionally substituted nitrogen-containing saturated heterocyclic group along with the adjacent nitrogen atom; and Ring A is an aromatic hydrocarbon, a monocyclic heteroaromatic ring or a condensed thiophene ring, or a pharmaceutically acceptable salt thereof.
