Investigation of the structure requirement for 5-HT₆ binding affinity of arylsulfonyl derivatives: a computational study.

ABSTRACT: 5-HT(6) receptor has been implicated in a series of diseases including anxiety, depression, schizophrenia and cognitive dysfunctions. 5-HT(6) ligands have been reported to play a significant role in the treatment for central nervous system (CNS) diseases. Presently, a large series of 223 5-HT(6) ligands were studied using a combinational method by 3D-QSAR, molecular docking and molecular dynamics calculations for further improvement of potency. The optimal 3D models exhibit satisfying statistical results with r(2) (ncv), q(2) values of 0.85 and 0.50 for CoMFA, 0.81 and 0.53 for CoMSIA, respectively. Their predictive powers were validated by external test set, showing r(2) (pred) of 0.71 and 0.76. The contour maps also provide a visual representation of contributions of steric, electrostati
