Abstract

A series of twenty-two metronidazole-triazole-styryl hybrids as antiamoebic agents were studied based on the combination of 3D-QSAR and surflex-docking. The CoMFA and CoMSIA models were carried out using eighteen compounds in the training set and four compounds in the test set gives Q 2 values of 0.684 and 0.664 respectively, and R 2 values of 0.882 and 0.894 respectively. The adapted alignment method with the suitable parameters resulted in reliable models. Based on contour maps produced by the CoMFA and CoMSIA, we suggested new compounds with high predicted activities, Surflex-docking revealed the important interactions between the ligand and receptor. Therefore, it confirmed the stability of predicted molecules in the receptor with PDB: 4CCQ.
