Quantitative structure-activity relationships of purines II: Prediction of activity against adenocarcinoma CA755 and
Journal of Pharmaceutical Sciences
|June 1, 1982
Abstract:
Quantitative structure-activity relationships (QSAR) were derived for a number of 2,6-mono- and disubstituted purines. The derived equations relate the anticancer activity in murine Adenocarcinoma CA755 to the molar refractivity of substituents at position 2 and electron-withdrawing effects of substituents at position 6. A QSAR was also derived for the acute toxicity (LD50) of substituents at position 6. The results suggest that toxicity is relatively independent of the nature of the substituent.
