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.

Process Development for ABT-472, a Benzimidazole PARP Inhibitor
摘要:
A nine-step convergent process was developed for the synthesis of ABT-472, a benzimidazole PARP inhibitor. The identity and origin of several impurities were determined, and the process was modified to reduce or eliminate these impurities. A number of safety and control issues were investigated. The original synthesis was shortened to 9 steps and streamlined while maintaining a convergent strategy. A stable salt was selected, and control of the API solid form was established. The process was successfully scaled up to provide 8.5 kg of final product of > 99% purity in 33% yield over 9 steps.
Inhibitors of poly(ADP-ribose)polymerase, ways to make them and methods of treating patients using them are disclosed.
