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
