The best predictive models by MIFs gave the cross-validated correlation coefficient, Q2 of 0.668 and squared correlation coefficient, R2 of 0.979 and the models by MLR, PCR and PLSR methods for 2D-QSAR provided a highly significant squared correlation coefficient (R2) values of 0.904, 0.785, 0.903 and cross-validated correlation coefficients (Q2) of 0.824, 0.662 and 0.718 respectively. The statistically significant model was established from a training set of 18 molecules, which were validated by evaluation of test set of 6 compounds. The calculated cytotoxic activities through MIFs model showed a very good agreement with experimental values. The information provided by QSAR analysis may give valuable clues to design and find the new potential drugs.
