香豆素-4-乙酰苄肼类抗结核病药物的3D-QSAR研究
QSAR studies of coumarin-4-acetic acid benzylidene hydrazides anti-tuberculosis drug using three-dimensional structure descriptors
摘要
Abstract
A newly developed three-dimensional holographic vector of atomic interaction field (3D-HoVAIF) was used to describe the chemical structures of 25 anti-tuberculosis drugs as coumarin-4-acetic acid benzylidene hydrazides. Here quantitative structure activity relationships (QSARs) model were built by multiple linear regression (MLR) and partial least square regression (PLS). The estimation stability and generalization ability of the model was strictly analyzed by both internal and external validations. The correlation coefficients of established MLR model and PLS model (Rcum), leave-one-out cross-validation (QLOO), predicted values versus experimental ones of external samples (Qext) were 0. 926, 0. 819, 0. 805 and 0. 919, 0. 828, 0. 836, respectively. The results indicated that QSAR models had both favorable estimation stability and good prediction capabilities. Satisfactory results showed that 3D-HoVAIF could preferably express information related to biological activity of hydra-zide derivatives.关键词
