摘要
To obtain useful information for identifying inhibitors of urate transporter 1 (URAT1), three-dimensional quantitative structure-activity relationship (3D-QSAR) analysis was conducted for a series of lesinurad analogs via Topomer comparative molecular field analysis (CoMFA). A 3D-QSAR model was established using a training set of 51 compounds and externally validated with a test set of 17 compounds. The Topomer CoMFA model obtained (q(2) = 0.976, r(2) = 0.990) was robust and satisfactory. Subsequently, seven compounds with significant URAT1 inhibitory activity were designed according to the contour maps produced by the Topomer CoMFA model.
