This communication discusses the discovery of novel reverse tricyclic pyridones as inhibitors of Janus kinase 2 (JAK2). By using a kinase cross screening approach coupled with molecular modeling, a unique inhibitor–water interaction was discovered to impart excellent broad kinase selectivity. Improvements in intrinsic potency were achieved by utilizing a rapid library approach, while targeted structural
该交流讨论了发现新的反向三环吡啶酮作为Janus激酶2(JAK2)抑制剂的发现。通过使用激酶交叉筛选方法与分子建模相结合,发现了独特的抑制剂与水的相互作用赋予了出色的宽泛的激酶选择性。通过使用快速文库方法可实现内在效力的提高,而针对性的结构变化可降低亲脂性,从而改善了大鼠的药代动力学。这种多管齐下的方法导致了31的鉴定,这证明了令人鼓舞的大鼠药代动力学,体内效力和出色的脱靶激酶选择性。
