摘要

本研究利用负责抗hiv活性的分子描述符估计了107种HEPT类似物的抗hiv活性(log1/C)。研究采用了MLR、ANN和SVM三种技术。MLR模型拟合训练集的R(2)=0.856,而在ANN和SVM中R(2)较高的值分别为0.850和0.874。支持向量机模型在估计训练数据的抗hiv活性方面有所改进,而在测试集上,ANN比MLR和SVM技术具有更高的R(2)值。R m (2) = metrics和ridge回归分析表明,提出的四变量模型MATS5e、RDF080u、T(O⋯O)和MATS5m作为相关描述符最适合估计当前化合物组的抗hiv活性(log 1/C)。

Estimation of Anti-HIV Activity of HEPT Analogues Using MLR, ANN, and SVM Techniques.

The present study deals with the estimation of the anti-HIV activity (log1/C) of a large set of 107 HEPT analogues using molecular descriptors which are responsible for the anti-HIV activity. The study has been undertaken by three techniques MLR, ANN, and SVM. The MLR model fits the train set with R (2)=0.856 while in ANN and SVM with higher values of R (2) = 0.850, 0.874, respectively. SVM model shows improvement to estimate the anti-HIV activity of trained data, while in test set ANN have higher R (2) value than those of MLR and SVM techniques. R m (2) = metrics and ridge regression analysis indicated that the proposed four-variable model MATS5e, RDF080u, T(O⋯O), and MATS5m as correlating descriptors is the best for estimating the anti-HIV activity (log 1/C) present set of compounds.
