英文摘要3D-QSAR models of Comparative of Molecular Field Analysis (CoMFA) and Comparative of Molecular Similarity Indices Analysis (CoMSIA) of 61 potent carbonic anhydrase II (CAII) sulfonamide inhibitors were performed using two methods. The conventional ligand-based 3D-QSAR studies were performed based on the lower energy conformations employing database alignment rule. The receptor-based 3D-QSAR models were also derived using bioactive conformations obtained by docking compounds to the active sites of CAII. The receptor-based model gave q(2) values of 0.623 and 0.562, r(2) values of 0.986 and 0.987 for CoMFA and CoMSIA, respectively, which were much better than those of ligand-based model (q(2) values of 0.532 and 0.466). The predictive ability of the models was validated using the test set of 10 compounds that were not included in the training set of 51 compounds. Results of CoMFA and CoMSIA suggested that heterocyclic sulfonamides are more active than aromatic sulfonamides, in the latter 1,3,5-triazole group substituting one hydrogen atom of the amido is favored and moderate groups in its 4- and 6-position are required. These results provided further understanding of the relationship between the structural features of CAII and its activities, which should be applicable to design and find new potential CAII inhibitors.
