Abstract
Three-dimensional quantitative structure–activity relationship (3D QSAR) studies were performed on acetylcholinesterase (AChE) inhibitors, based on molecular docking scores obtained by using FlexX and FlexiDock and comparative molecular field analysis (CoMFA). The docking scores were used as molecular descriptors along with the steric and electrostatic field values of CoMFA, for partial least square (PLS) analysis. The high leave one out (LOO) cross-validated correlation coefficient ( q 2 = 0.714) reveals that the model is a useful tool for the prediction of test set as well as newly designed structures against AChE activity. The superimposed CoMFA models on the receptor site of AChE are guiding the design of potential inhibitory structures directed against AChE activity.
