  发现 TRD-93 作为新型 DRAK2 抑制剂

  摘要：

  死亡相关蛋白激酶相关凋亡诱导蛋白激酶 2 (DRAK2) 已成为药物开发的有前途的目标。为了寻找新型和选择性 DRAK2 抑制剂基序，建立了使用内部化学库进行的体外筛选激酶测定。经过命中分类程序，N 2 -(3,5-二氯苯基)-5-氟-N 4 -甲基嘧啶-2,4-二胺( 1 )被选为具有结构新颖性和药物相似性的初始命中。在命中验证期间，彻底揭示了 1 的构效关系，TRD-93最终被验证为 DRAK2 抑制的命中。TRD-93很小 (mw = 290) 但对 DRAK2 (IC 50 = 0.16 μM）超过其他激酶，包括 DAPK 家族激酶。还讨论了TRD-93与 DRAK2的分子结合模型研究。
