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.

Quantitative structure activity relationship studies on 3-triazines using van der Waal volume and molecular connectivity index.

QSAR studies have been performed on the homologues of 3-triazines, using molecular connectivity index and van der Waal volume as structural parameters. The regression analysis has shown good correlation between antitumour activity and the two structural parameters.
