In this paper, the three dimensional pharmacophore model of two kinds of HCV NS3 serine protease inhibitors was obtained by using the CATALYST software. Although these two kinds of inhibitors possess quite different structures,yet a common pharmacophore model with very good statistical results can be determined. The results uncover that these two kinds of molecules will take the similar pattern when they interact with the receptor. Based on the pharmacophore model, a 3D-QSAR analysis was performed and the model showed good predictive ability (correlation coefficient R=0.89).

Key words: HCV NS3 serine protease inhibitors, Pharmacophore model, 3D-QSAR, CATALYST software
