Quantum QSAR of the antirhinoviral activity of 9-benzylpurines.

Abstract

The antirhinoviral activity of previously described 9-benzylpurines was quantitatively analysed using Huckel molecular orbital generated electronic parameters and physicochemical properties of substituents. Correlations with the activity against each of several serotypes of the virus were obtained but very few common requirements emerged. Our results emphasise the difficulties in identifying a compound with optimum structural features for broad spectrum antirhinovirus activity.
