Quantitative structure-activity relationship studies on some anticancerous, antiviral and cytostatic agents.

QSAR studies using molecular connectivity and van der Waal volume have been performed on a new series of hydroxyguanidine derivatives and a series of isoindolediones. Regression analysis has shown that anticancer and antiviral activity of hydroxyguanidines as well as cytostatic activity of isoindolediones correlate well with both the structural parameters.
