摘要

Aim: To discriminate between fentanyl derivatives with high and low activities.Methods: The support vector classification (SVC) method, a novel approach,was employed to investigate structure-activity relationship (SAR) of fentanyl derivatives based on the molecular descriptors, which were quantum parameters including △E [energy difference between highest occupied molecular orbital energy (HOMO) and lowest empty molecular orbital energy (LUMO)], MR(molecular refractivity) and Mr (molecular weight). Results: By using leave-oneout cross-validation test, the accuracies of prediction for activities of fentanyl derivatives in SVC, principal component analysis (PCA), artificial neural network (ANN) and K-nearest neighbor (KNN) models were 93%, 86%, 57%, and 71%, respectively. The results indicated that the performance of the SVC model was better than those of PCA, ANN, and KNN models for this data. Conclusion:SVC can be used to investigate SAR of fentanyl derivatives and could be a promising tool in the field of SAR research.
