Resumen
It was shown that the two different methods, the principal component analysis (PCA) and the neural network (NN), can classify oral progestational activity of substituted 17 alpha-acetoxyprogesterones into two categories, high active and low active, using only calculated molecular properties. The two methods can predict the category of each molecule with a fairly high percentage of success. The NN work was slightly better than the PCA in the prediction of the category. Ionization potential, molecular hardness, net atomic charges, frontier indices were found to be useful parameters for the classification of the compounds. (C) 1999 Elsevier Science B.V.
