  发现口服生物可利用的选择性 PKMYT1 抑制剂 RP-6306

  摘要：

  PKMYT1 是 CDK1 磷酸化的调节剂，由于其与CCNE1扩增建立的合成致死关系，因此成为治疗某些类型 DNA 损伤反应癌症的引人注目的治疗靶点。迄今为止，尚未报道该激酶的选择性抑制剂可用于研究 PKMYT1 的药理作用。为了满足这一需求，化合物1被确定为弱 PKMYT1 抑制剂。引入二甲基苯酚可增加对 PKMYT1 的效力。人们发现这些二甲基苯酚类似物以阻转异构体的形式存在，可以将其分离并分析为单一对映异构体。基于结构的药物设计能够优化基于细胞的效力。ADME 特性的并行优化导致鉴定出 PKMYT1 的有效且选择性抑制剂。RP-6306在多种临床前异种移植模型中抑制CCNE1扩增的肿瘤细胞生长。一流的临床候选药物RP-6306目前正在评估用于治疗各种实体瘤的 1 期临床试验。
