  Discovery and SAR of 2-(1-propylpiperidin-4-yl)-1H-benzimidazole-4-carboxamide: A potent inhibitor of poly(ADP-ribose) polymerase (PARP) for the treatment of cancer

  摘要：

  We have developed a series of cyclic amine-containing benzimidazole carboxamide poly( ADPribose) polymerase ( PARP) inhibitors, with good PARP-1 enzyme potency, as well as cellular potency. These efforts led to the identification of a lead preclinical candidate, 10b, 2-(1-propylpiperidin-4-yl)-1H-benzimidazole- 4-carboxamide (A-620223). 10b displayed very good potency against both the PARP-1 enzyme with a K-i of 8 nM and in a whole cell assay with an EC50 of 3 nM. 10b is aqueous soluble, orally bioavailable across multiple species, and demonstrated good in vivo efficacy in a B16F10 subcutaneous murine melanoma model in combination with temozolomide ( TMZ) and in an MX-1 breast xenograph model in combination with cisplatin.
