The discovery of a back-up to the hepatitis C virus NS3 protease inhibitor asunaprevir (2) is described. The objective of this work was the identification of a drug with antiviral properties and toxicology parameters similar to 2, but with a preclinical pharmacokinetic (PK) profile that was predictive of once-daily dosing. Critical to this discovery process was the employment of an ex vivo cardiovascular
描述了对丙型肝炎病毒NS3蛋白酶抑制剂asunaprevir(2)的备份的发现。这项工作的目的是鉴定一种具有类似于2的抗病毒特性和毒理学参数,但具有可预测每天一次给药的临床前药代动力学(PK)谱的药物。该发现过程的关键是采用离体心血管(CV)模型,该模型可用于识别与2一样没有导致BMS-605339(1)退出临床试验的CV负债的化合物。2个结构子站点中每个结构子站点之间的结构活动关系(SAR)通过在P1位点进行修饰,探索了PK的显着改善,同时发现了对P4进行了细微但合理设计的结构变化后,药效有所提高。为了优化CV轮廓,需要在P3处进行其他修改,并且这些组合的SAR导致了BMS-890068的发现(29)。
