摘要:

本文通过简单可行的方法合成了一个4-苯胺喹唑啉衍生物1, 并通过分子对接的方法探讨了其JAK3抑制活性的分子作用机制。结果表明, 化合物1与JAK3蛋白中ATP活性位点的关键氨基酸残基有一系列的相互作用, 对JAK3蛋白的亲和力高于JANEX-1和Tasocitinib, 呈现较强的JAK3抑制活性。

关键词: 4-苯胺喹唑啉类, 合成, JAK3激酶, 分子对接

Abstract:

A 4-anilinoquinazoline derivative (1) designed as a JAK3 inhibitor was synthesized in high yield by a practical and efficient method. The molecular docking study was also performed to elucidate the molecular mechanism of the JAK3 inhibitory potency of compound 1. The results indicated that compound 1 had various interactions with the key amino acid residues at the ATP-binding cavity of JAK3 protein and presented high affinity to JAK3 protein, which was even higher than JANEX-1 and Tasocitinib.

Key words: 4-Anilinoquinazoline, Synthesis, JAK3 kinase, Molecular docking
