QSAR analysis of a series of previously synthesised 1-(1H-1,2,4-triazole-1-yl)-2-(2,4-difluorophenyl)-3-substituted-2- propanols(TDFPP) as analogues of fluconazole were tested for growth inhibitory activity against Candida albicans using computer assisted multiple regression analysis. This was in order to explore the selectivity requirements for fungicidal activity against C. albicans among these congeners. A training set comprising 40 analogues and a test set comprising ten analogues of 1-(1H-1, 2, 4-triazole-1-yl)-2-(2,4-difluorophenyl)-3-substituted-2-propanols were selected for the present investigation by using the sphere exclusion method embedded in the Vlife MDS 3.5 software. With respect to the modelling of the growth inhibitory activity of the reported compounds, the regression analysis shows that even in the mono-parametric correlations the topological and physicochemical parameters give significant regression coefficients. The validation of the QSAR models was performed by cross-validation and external test set prediction. The model is not only able to predict the activity of new compounds but also explains the important region in the molecules in a quantitative manner.
