Patent ID: 7919495

Claim:
A pyridyl non-aromatic nitrogen-containing heterocyclic-1-carboxylate compound of a general formula (III) or its pharmaceutically acceptable salt: wherein the symbols in formula (III) have the following meanings: ring A represents benzene ring, cyclopentane ring, cyclohexane ring, cycloheptane ring, or 5- to 7-membered nitrogen-containing hetero ring; L represents single bond, lower alkylene, lower alkenylene, —N(R 15 )—C(═O)—, —C(═O)—N(R 15 )—, -(lower alkenylene)-C(═O)—, —O—, or —C(═O)—; R 15 represents H, or lower alkyl; X represents CH, or N; R 8 , R 9 , and R 10 are the same or different, each representing (i) a group selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; (ii) aryl optionally substituted with the same or different 1 to 5 groups selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; (iii) nitrogen-containing heteroaryl optionally substituted with the same or different 1 to 5 groups selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; (iv) R 16 —(lower alkylene)-O—; (v) R 16 —(lower alkylene)-N(R 15 )—; or (vi) R 17 R 18 N—C(═O)—, wherein R 16 represents (i) aryl optionally substituted with the same or different 1 to 5 groups selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; (ii) nitrogen-containing heteroaryl optionally substituted with the same or different 1 to 5 groups selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; or (iii) 3- to 8-membered cycloalkyl, wherein R 17 and R 18 are the same or different, each representing H, lower alkyl, or 3- to 8-membered cycloalkyl, or R 17 and R 18 may form, together with the N atom bonding thereto, 3- to 8-membered nitrogen-containing hetero ring, R 11 represents H, lower alkyl, or oxo (═O), and one of R 12 , R 13 and R 14 is —C(═O)—O-(lower alkyl) or —CO 2 H, and the others are H.
