RESUMEN
Objective:To establish a three-dimensional quantitative structure-activity relationship (3D-QSAR) model for thiazide 11β-hydroxy steroid dehydrogenase ( HSD) inhibitors in order to perform structure modification and find thiazide 11β-HSD inhibitors with more activity. Methods: The 3D-QSAR model of thiazine derivatives was constructed by the method of comparative molecular force field analysis, and the model was validated by using a molecular docking method. Results:An accurate 3D-QSAR model of 11β-HSD inhibitors was obtained (CoMFA:q2 =0. 346, r2 =0. 850, where q2 was the cross-validation coefficient and r2 was the non-cross validation coefficient) . Conclusion:The results provide important theoretical basis for the rational design of novel thiazide 11β-HSD inhibitors.
