We performed a predictive analysis based on Quantitative Structure-Activity Relationships (QSAR) of an important property of flavonoids which is the inhibition (IC50) of Aldose Reductase (AR). The importance of AR inhibition is that it prevents cataract formation in diabetic patients. The best linear model constructed from 55 molecular structures incorporated six molecular descriptors, selected from more than a thousand geometrical, topological, quantum-mechanical and electronic types of descriptors. As a practical application we used the obtained QSAR model to predict the AR inhibitory effect of newly synthesized flavonoids, displaying 2-, 7-substitutions in the benzopyrane backbone.
