QSAR analysis of a set of previously synthesized azole derivatives tested for growth inhibitory activity against Candida albicans was performed by using Associative Neural Network. To overcome the problem of overfitting due to descriptor selection, 5-fold cross-validation with variable selection in each step of the analysis was used. The predictive ability of the models was tested through leave-one-out cross-validation, giving a Q2 = 0.77 - 0.79 for regression models. Predictions for the external evaluation sets obtained accuracies in the range of 0.70 - 0.80 for regressions. Biological testing of compounds was performed by disco-diffusion method on solid medium culture versus strain C. albicans ATCC 10231 M885. Most of compounds demonstrated high antifungal activity. Five synthesized compounds also showed activity against clinical isolate strain of C. albicans received from a biological material and resistant to fluconazole.
