ABSTRACT

OBJECTIVE:To virtually screen potential α-glycosidase inhibitor ingredients from C. mori and F. mori,and to pro-vide reference for finding out new typeα-glycosidase inhibitor ingredient. METHODS:Surflex-Dock module of Sybyl-x 2.0 molecu-lar simulation software was used to perform the docking of small molecule compound,which was from the ingredients of C. mori and F. mori as ligand stated in literatures,with α-glycosidase. Total score of affinity scoring function was equal to 7 as the thresh-old value,to judge potential α-glycosidase inhibitor ingredient in C. mori and F. mori. RESULTS:After 70 small molecule com-pounds docked with α-glycosidase, 10 compounds showed binding activity (Total score≥7.00). Among them, moracin M-3′-O-β-D-glucopyranoside,5,7,2′-trihydroxyflavanone-4′-O-β-D-glucoside,mulberroside A,resveratrol-4,3′-di-O-β-D-gluco-pyranoside and 1,4-dideoxy-1,4-imino-(2-O-β-D-glucopyranosyl)-D-arabinitol had higher binding activity with α-glycosidase(Total score>8.00). CONCLUSIONS:Multi-constituents of C. mori and F. Mori show potential α-glycosidase inhibitory activity. The method is a kind of highly targeted,rapid and efficient approach to discover α-glycosidase inhibitor from traditional Chinese medi-cine.
