Benzimidazole-4-carboxamide compounds (I) which can act as potent inhibitors of the DNA repair enzyme poly(ADP-ribose) polymerase or PARP enzyme (EC 2.4.2.30), and which thereby can provide useful therapeutic compounds for use in conjunction with DNA-damaging cytotoxic drugs or radiotherapy to potentiate the effects of the latter. In formula (I), R and R' may each be selected independently from hydrogen, alkyl, hydroxyalkyl (e.g. CH.sub.2 CH.sub.2 OH), acyl (e.g. acetyl or benzoyl) or an optionally substituted aryl (e.g. phenyl) or aralkyl (e.g. benzyl or carboxybenzyl) group. R is generally a substituted phenyl group in the most preferred compounds. The compounds may also be used in the form of pharmaceutically acceptable salts or pro-drugs. ##STR1##
苯并咪唑-4-羧酰胺化合物(I)可作为DNA修复酶聚(ADP-核糖)聚合酶或PARP酶(EC 2.4.2.30)的强效抑制剂,从而可提供用于与DNA损伤细胞毒性药物或放疗结合使用以增强后者效果的有用治疗化合物。在式(I)中,R和R'可以分别选择为氢、烷基、羟基烷基(例如CH.sub.2 CH.sub.2 OH)、酰基(例如乙酰基或苯甲酰基)或可选择取代的芳基(例如苯基)或芳基烷基(例如苄基或羧基苄基)基团。在大多数首选化合物中,R通常是取代苯基团。这些化合物也可以以药用盐或前药的形式使用。
