  有力和选择性的布鲁顿酪氨酸激酶抑制剂：GDC-0834的发现

  摘要：

  SAR研究专注于改善先前报道的有效和选择性Btk抑制剂CGI-1746（1）的药代动力学（PK）特性，从而产生了临床候选药物GDC-0834（2），该药物保留了CGI-1746的效力和选择性，但在临床前动物模型中改善了PK。基于结构的设计工作推动了这项工作，因为在溶剂暴露区域以及“ H3结合口袋”处都对1的修饰进行了研究。但是，体外代谢评价为2揭示了一种非CYP介导的代谢过程，在人类中比临床前物种（小鼠，大鼠，狗，猕猴）更普遍，从而导致在预测人类药代动力学方面存在高度不确定性。由于其有希望的效价，选择性和临床前功效，因此在健康志愿者中进行了单剂量IND并接受了2项单剂量I期试验，以快速评估人的药代动力学。在人类中，发现2在将四氢苯并噻吩部分连接至中央苯胺环的环外酰胺键上非常不稳定，从而导致母体药物暴露不足。该信息为备份计划和改进抑制剂的发现提供了信息。

  We describe the hit-to-lead exploration of a [1,2,4]triazolo[1,5-a]pyrimidine phosphodiesterase 2A (PDE2A) inhibitor arising from high-throughput screening. X-ray crystallography enabled structure-guided design, leading to the identification of preferred substructural components. Further rounds of optimization used relative binding free-energy calculations to prioritize different substituents from
