Abstract (EN):
A QSAR study is reported to predict the binding affinity of a set of 81 modulators for both of human estrogen receptor alpha and beta (ER alpha and ER beta). In this study, the derived QSAR models were built by forward stepwise multilinear regression (MLR) and nonlinear radial basis function neural networks (RBFNN), respectively. The statistical characteristics of the external test set provided by multiple linear model (R-2=0.814, F=61.277, RMS=0.5461 for ER alpha; R-2=0.600, F=21.039, RMS=0.6707 for ER beta) indicated satisfactory stability and predictive ability of the model built. The predictive ability for ER beta of RBFNN model is somewhat superior: R2=0.7691, F=32.012, RMS=0.5764, and the similar result was obtained for ERa of the test set: R2=0.7950, F=54.131 RMS=0.3120. Overall, the appropriate results proved the models to be meaningful and useful to predict and virtual screen of the derivatives with high binding activity.
