We recently reported 1a (skepinone-L) as a type I p38α MAP kinase inhibitor with high potency and excellent selectivity in vitro and in vivo. However, as a type I inhibitor, it is entirely ATP-competitive and shows just a moderate residence time. Thus, the scope was to develop a new class of advanced compounds maintaining the structural binding features of skepinone-L scaffold like inducing a glycine
我们最近报告了1a(skepinone-L)作为I型p38αMAP激酶抑制剂,在体外和体内均具有很高的效价和出色的选择性。但是,作为I型抑制剂,它完全具有ATP竞争能力,并且仅显示适度的停留时间。因此,研究范围是开发一种新型的高级化合物,该化合物可维持skepinone-L支架的结构结合特征,例如在铰链区诱导甘氨酸翻转,并同时占据疏水区I和II。用适当的残基扩展该支架会干扰激酶的R-Spine。通过合成69种化合物,我们可以将一个实例的目标停留时间显着延长至3663 s,同时具有出色的选择性得分0.006和出色的效能1.0 nM。通过共结晶验证了这种新的结合模式,1 / 2的结合。此外,微粒体研究显示了最有效的,本文报道的代表的便利的代谢稳定性。
