Inhibitors of poly(adenosine diphosphate ribose) polymerase potentiate the antitumor activity of bleomycin against Ehrlich ascites carcinoma.

Abstract
M-Aminobenzamide and benzamide, which are potent inhibitors of poly (adenosine diphosphate ribose) polymerase and have no antitumor activity themselves, potentiated the antitumor activity of bleomycin against Ehrlich ascites carcinoma in vivo.
