In this work we present the fundamentals of MTD method together with its application for QSAR study of a series of flavones as inhibitors of aldose reductase. The percentage inhibition of enzyme activity was represented by molar concentration.

The geometry of flavone derivatives has been optimized by MM+ and AM1 computer programs and a conformational analysis was performed. On the basis of computational results, the hypermolecule H was constructed by seeking the maximal superposition of the flavone derivatives. Hypermolecule H allows the mapping of receptor space in the frame of MTD algorithm.

The optimized receptor map obtained by the MTD method offers some insights about the beneficial and detrimental zones of flavone derivatives.
