摘要: The study on antitumor activities of artemisinin and its derivatives has been closely focused on in recent years. Herein, 2D and 3D QSAR analysis was performed on the basis of a series of artemisinin derivatives with known bioactivities against the non-small-cell lung adenocarcinoma A549 cells. Four QSAR models were successfully established by CoMSIA, CoMFA, topomer CoMFA and HQSAR approaches with respective characteristic values q2=0.567, R2=0.968, ONC=5; q2=0.547, R2=0.980, ONC=7; q2=0.559, R2=0.921, ONC=7 and q2=0.527, R2=0.921, ONC=6. The predictive ability of CoMSIA with r2=0.991 is the best one compared with the other three approaches, such as CoMFA (r2=0.787), topomer CoMFA (r2=0.819) and HQSAR (r2=0.743). The final QSAR models can provide guidance in structural modification of artemisinin derivatives to improve their anticancer activities.
