Abstract
Three series of xanthone sulfonamides were synthesized, and their inhibitory activities against acyl-CoA: cholesterol acyltransferase (ACAT) were evaluated. Results showed that most of the title compounds exhibited strong inhibitory activity against ACAT, of which compounds 1c, 1e, 1f, 2d, 2e, and 3d were proved to be more active than the positive control Sandoz 58-035. Computational docking experiments indicated that the interaction between inhibitors and ACAT contained the H-bond interaction, the hydrophobic interaction, and the narrow hydrophobic cleft.
Keywords:
ACAT; Structure-activity relationship; docking; sulfonamide; xanthone.
