英文摘要 | aim: to develop an artificial neural network model for predicting the resistance index (ri) of taxoids. methods: a dataset of 63 experimental data points were compiled from published studies and randomly subdivided into training and external test sets. electrotopological state (e-state) indices were calculated to characterize molecular structure together with a principle component analysis to reduce the variable space and analyze the relative importance of e-state indices. back propagation neural network technique was used to build the models. five-fold cross-validation was performed and 5 models with different compound composition in training and validation sets were built. the independent external test set was used to evaluate the predictive ability of models. results: the final model proved to be good with the cross-validation q(cv)(2)0.62, external testing r-2 0.84, and the slope of the regression line through the origin for the testing set at 0.9933. conclusion: the quantitative structure-activity relationship model can predict the ri to a relative nicety, which will aid in the development of new anti-multidrug resistance taxoids. |
