Claim:
A compound represented by the following formula, a salt thereof or a hydrate of them wherein Z 11 and Z 12 each independently represent a carbonyl group, an oxygen atom, a sulfur atom, or a methine group which may be substituted, a methylene group which may be substituted or a nitrogen atom which may be substituted; represents a double bond or a single bond; R 1a represents a hydrogen atom, a C 1 -C 6 alkyl group, a phenyl group or a benzyl group; R 2a , R 2b and R 2c each independently represent a group selected from Substituent Group (a); the ring A represents a benzene ring which may have one to three groups selected from Substituent Group (a), a naphthalene ring which may have one to three groups selected from Substituent Group (a) or a 5- to 10-membered aromatic heterocyclic ring which may have one to three groups selected from Substituent Group (a); Substituent Group (a) (1) a hydrogen atom, (2) halogen atoms, (3) a nitro group, (4) a hydroxyl group, (5) a cyano group, (6) a carboxyl group, (7) an amino group, (8) a formyl group or (9) a group represented by the formula: wherein X 1 and X 2 each independently represent a single bond, —CO—, —SO 2 — or C 1 -C 6 -methylene group; X 3 represents a single bond, —CO—, —SO 2 , —O—, —CO—O— or —O—CO—; R 3b represents a C 1 -C 6 alkylene group or a single bond; R 3a and R 3c represent a hydrogen atom, a C 1 -C 6 alkyl group which may be substituted, a C 2 -C 6 alkenyl group which may be substituted, a C 2 -C 6 alkynyl group which may be substituted, a C 3 -C 8 cycloalkyl group which may be substituted, a C 6 -C 14 aromatic cyclic hydrocarbon group which may be substituted, a 5- to 14-membered aromatic heterocyclic group which may be substituted or a hydrogen atom, provided that 6,7-dihydrobenzo[1,2]cyclohepta[3,4,5-cd]indazole is excluded.
