The development of a series of novel 7-azabenzofurans exhibiting pan-genotype inhibition of HCV NS5B polymerase via binding to the primer grip site is presented. Many challenges, including poor oral bioavailability, high clearance, bioactivation, high human serum shift, and metabolic stability were encountered and overcome through SAR studies. This work culminated in the selection of BMS-986139 (43)
介绍了一系列新型 7-氮杂
苯并呋喃的开发,这些新型 7-氮杂
苯并呋喃通过与引物夹位点结合,表现出对 HCV NS5B 聚合酶的全
基因型抑制。
SAR 研究遇到并克服了许多挑战,包括口服
生物利用度差、清除率高、
生物活性高、人血清变化高和代谢稳定性等。这项工作最终选择 BMS-986139 ( 43 ) 作为临床前候选药物。
