A condensed heterocyclic compound having poly(adenosine 5'-diphospho- ribose)polymerase (PARP) inhibitory activity represented by the formula (I): wherein R1 is hydrogen, halogen, lower alkyl or lower alkoxy, A and two adjacent carbon atoms of the six membered ring to be bonded with A form benzene ring, pyridine ring, etc, -Y1=Y2- is formula (II) wherein L11, L12, L13 and L14 is (1) lower alkylene, (2) lower alkenylene, etc, and R21, R22 , R23 and R24 is (1) cyclic amino group, which is substituted with phenyl optionally substituted with one or more suitable substituent(s), etc. provided that when A and two adjacent carbon atoms of the six membered ring to be bonded with A form benzene ring, then -Y1=Y2- is formula (III) or its prodrug, or their salts.

L'invention concerne un composé hétérocyclique condensé présentant une activité inhibitrice de la poly(adénosine-5'-diphospho-ribose) polymérase (PARP) et représenté par la formule (I), ou son promédicament ou ses sels. Dans la formule (I), R?1¿ représente hydrogène, halogène, alkyle inférieur ou alcoxy inférieur, A et deux atomes de carbone adjacents du noyau à six éléments devant être lié à A forment un noyau benzène, un noyau pyridine, etc. -Y?1¿=Y?2¿- représente (II), où L?11¿, L?12¿ et L?14¿ représentent (1) alkylène inférieur, (2) alcénylène inférieur, etc. et R?21¿, R?22¿, R?23¿ et R?24¿ représentent (1) un groupe amino cyclique, qui est substitué par phényle éventuellement substitué par un ou plusieurs substituants appropriés, etc. à la condition que lorsque A et deux atomes de carbone adjacents du noyau à six éléments devant être lié à A forment un noyau benzène, -Y?1¿=Y?2¿- représente (III).
