Patent ID: 7772226

Claim:
A compound represented by the following formula, or a salt thereof, wherein, T 1 is a group represented by the following formula: (wherein, n and m each independently represent 0 or 1) which may have one or more substituents selected from the substituent group S described below; X represents a C 2-6 alkynyl group or a C 6-10 aryl C 1-6 alkyl group; Z 1 and Z 2 each represent a group represented by the formula —CR 2 ═; R 1 is H; R 2 represents H or a group according to the formula -A 0 -A 1 -A 2 (wherein A 0 represents a single bond; A 1 represents a single bond or a group represented by the formula —CO—O—; A 2 is a C 1-6 alkyl group; however, A 2 may have 1 to 3 substituents selected from the substituent group B described below: Substituent group B represents the group consisting of: a hydroxyl group, a C 1-6 alkoxy group, a C 1-6 alkylthio group, and a group represented by the formula —NR B1 —R B2 (where R B1 and R B2 each independently represent a hydrogen atom or a C 1-6 alkyl group)); wherein, Substituent group S represents the group consisting of: a formyl group, a carboxyl group, and a group represented by the formula -T 1x -T 2x (where T 1x is a group represented by the formula —CO—, a group represented by the formula —CO—O—, or a group represented by the formula —CO—NR T —; T 2x represents a hydrogen atom, or a C 1-6 alkyl group; R T represents a hydrogen atom, or a C 1-6 alkyl group).
