【Abstract】 in this paper, the non-linear relationship between the characteristic parameters and analgesic activities of a series of fentanyl derivatives is calculated by self-organization neural tree model. The results show that the performance of the self-organization neural tree is good and the successful claasification rate is rather nigh. Therefore, the model might be used ac an effective assistant technique for the investigation of structure-activity relationship of drugs.更多还原
