In the present work in mathematical modelling, quantitative structure activity relationship (QSAR) studies were performed on some 5,6-dihydro-2-pyrones derivatives using statistical work.Using only 4 topological and physico-chemical molecular descriptors, we have achieved 84.72% correct classification of the compounds with and without its activity. A heurisimatedtic algorithm selects the best multiple linear regression(MLR) equation showed the correlation between the observed values and the estimated values of activity is very good(R=0.9204, R2 =O.8472, PRESS=0.7357, =0.8197, SPRESS =0.2080). The results are discussed in the light of the main factors that influence the inhibitory activity of the HIV-1 protease.
