Patent ID: 8193356

Claim:
A compound represented by the following formula (1): wherein the ring A represents a 6-membered heterocycle containing a nitrogen atom as a heteroatom; the ring B represents a benzene ring; —R 6 — represents a direct bond, the ring C is an aromatic or nonaromatic ring and represents a heterocycle represented by the following formula (1c-1) or (1c-2): wherein each of R 4 and R 5 represents a hydrogen atom; each of —R 6a — and —R 6b — corresponds to the —R 6 —, the —R 6a — represents a direct bond, the —R 6b — represents a direct bond, r is 1, s is 1; the ring D represents a nitrogen atom-containing unsaturated 6-membered ring having an oxo group at 2-position; R 1 represents an alkyl group comprising a substituent represented by the following formula (1e): wherein the ring E represents a heterocycle containing at least one heteroatom selected from the group consisting of a nitrogen atom, an oxygen atom, and a sulfur atom, or a carbocycle; R 7 represents a substituent selected from the group consisting of a halogen atom, a hydroxyl group, a cyano group, a nitro group, an alkyl group, a halogencontaining alkyl group, an alkoxy group, a halogen-containing alkoxy group, a carboxyl group, an alkoxycarbonyl group, an acyl group, an acyloxy group, a carboxyalkyl group, an alkoxycarbonylalkyl group, an amino group, an N-substituted amino group, a ureido group, a sulfonic acid group, a sulfinic acid group, an alkylsulfonyl group, and a sulfonamide group; and t denotes 0 or 1; R 2 represents a methyl group; R 3 represents a substituent selected from the group consisting of a halogen-containing alkyl group and a halogen-containing alkoxy group; p and q are the same or different and each denotes 0 or 1; when the group R 1 is a straight chain C 1-3 alkyl group having a benzene ring, a thiophene ring, or a pyridine ring as the ring E, p is 0, and a fused ring comprising the ring A and the ring D is a fused ring represented by the following formula: at least one of the ring B and the ring E has at least one member selected from the group consisting of a halogen-containing alkyl group and a halogen-containing alkoxy group as the substituent R 3 and/or R 7 ; and R 4 , R 5 , —R 6 —, r, s, and t have the same meanings as defined above; or a salt thereof.
