A novel class of highly selective inhibitors of p38 MAP kinase was discovered from high throughput screening. The synthesis and optimization of a series of 5-amino-N-phenyl-1H-pyrazol-4-yl-3-phenylmethanones is described. An X-ray crystal structure of this series bound in the ATP binding pocket of unphosphorylated p38alpha established the presence of a unique hydrogen bond between the exocyclic amine
从高通量筛选中发现了一类新型的p38 MAP激酶高选择性抑制剂。描述了一系列5-氨基-N-苯基-1H-吡唑-4-基-3-苯基甲酮的合成和优化。在未磷酸化的p38alpha的ATP结合口袋中结合的该系列X射线晶体结构确定了抑制剂的环外胺与苏氨酸106之间存在独特的氢键,这可能有助于p38的选择性。晶体学信息被用来优化该系列的效力和理化性质。在吡唑支架上掺入2,3-二羟基丙氧基部分产生具有优异的类药物性质的化合物,包括高的口服生物利用度。
