of a known apoptosis signal-regulating kinase 1 (ASK1) inhibitor bound to its kinase domain led to the design and synthesis of the novel macrocyclic inhibitor 8 (cell IC50 = 1.2 μM). The profile of this compound was optimized for CNS penetration following two independent strategies: a rational design approach leading to 19 and a parallel synthesis approach leading to 26. Both analogs are potent ASK1
结合其激酶结构域的已知凋亡信号调节激酶1(ASK1)抑制剂的结构分析导致了新型大环抑制剂8的设计和合成(细胞IC 50 = 1.2μM)。该化合物的概况针对以下两种独立策略针对CNS渗透进行了优化:导致19的合理设计方法和导致26的平行合成方法。两种类似物在生化和细胞分析中均是有效的ASK1抑制剂(19,细胞IC 50 = 95 nM; 26,细胞IC 50 = 123 nM),在MDR1-MDCK分析中具有中低外排比(ER)(19,ER = 5.2; 26,ER = 1.5)。体内PK研究表明,抑制剂19具有中等的CNS渗透性(K puu = 0.17),类似物26具有较高的CNS渗透性(K puu = 1.0)。
