3D-QSAR Study of the Chalcone Derivatives as Anticancer Agents

الملخص EN

For their biological properties and particularly for their anticancer activities, chalcones are widely studied.

In this work, we have submitted diverse sets of chalcone derivatives to the 3D-QSAR (3-dimensional quantitative structural-activity relationship) to study their anticancer activities against HTC116 (human colon cancer), relying on the 3-dimensional descriptors: steric and electrostatic descriptors for the CoMFA (comparative molecular field analysis) method and steric, electrostatic, hydrophobic, H-bond donor, and H-bond acceptor descriptors for the CoMSIA method.

CoMFA as well as the CoMSIA model have encouraging values of the cross-validation coefficient (Q2) of 0.608 and 0.806 and conventional correlation coefficient (R2) of 0.960 and 0.934, respectively.

Furthermore, values of R2test have been obtained as 0.75 and 0.90, respectively.

Besides, y-randomization test was also performed to validate our 3D-QSAR models.

Based on these satisfactory results, ten new compounds have been designed and predicted by in silico ADMET method.

This study could expand the understanding of chalcone derivatives as anticancer agents and would be of great help in lead optimization for early drug discovery of highly potent anticancer activity.
