         Silent information regulator 2 homologue one (SIRT1) modulators have therapeutic potential
            for a number of diseases like cardiovascular, metabolic, inflammatory and age related
            disorders. Here, we have studied both activators and inhibitors of SIRT1 and constructed
            differential quantitative structure activity relationship (QSAR) models using CORAL
            software by Monte Carlo optimization method and SMILES notation. 3 splits divided
            into 3 subsets: sub-training, calibration and test sets, were examined and validated
            with a prediction set. All the described models were statistically significant models.
            The values of sensitivity, specificity, accuracy and Matthews’ correlation coefficient
            for the validation set of best model were 1.0000, 0.8889, 0.9524 and 0.9058, respectively.
            In mechanistic interpretation, structural features important for SIRT1 activation
            and inhibition have been defined.
