kinases including the MAPK isoforms p38(alpha,beta,gamma,delta), JNK1/2/3, and ERK1/2/8 showing 3-(4-fluorophenyl)-4-pyridin-4-ylquinolin-2(1H)-one (1) to be highly selective for p38alphaMAPK with an IC(50) of 1.8 microM. In contrast, besides p38alpha the isoxazoles 2 and 3 significantly inhibited JNK2/3 and further kinases beyond the MAPK family such as PKA, PKD, Lck, and CK1. By using sequence alignment
在这项研究中,我们报告了MAP激酶抑制剂1、2和3在78种蛋白激酶(包括MAPK亚型p38(α,β,γ,δ),JNK1 / 2/3和ERK1)中的特异性谱。 / 2/8显示3-(4-氟苯基)-4-吡啶-4-基喹啉-2(1H)-一(1)对p38alphaMAPK具有高度选择性,IC(50)为1.8 microM。相反,除了p38alpha以外,异恶唑2和3还显着抑制JNK2 / 3和MAPK家族以外的其他激酶,例如PKA,PKD,Lck和CK1。通过使用序列比对和MAPK家族的不同成员的同源性模型,研究了确定p38alpha同工型的选择性的结合模式。对于1的铅优化,采用了一种简单的串联-布赫瓦尔德-阿尔道合成方法来对喹啉2(1H)-一个脚手架进行灵活的装饰。
