Abstract: Sulfonic acid stilbenes block the infection of cells by HSV and CMV and these compounds can be used to treat viral infection.

Abstract: The preferred oligomers of the present invention are polyureas, polycarbonates, polyesters or polyamides having a number average molecular weight of <10,000. These oligomers are water-soluble, have a rigid backbone, have recurring units coupled by carbonyl linking moieties which have anionic groups, display predominantly linear geomentry such that regular spacing between anionic groups exists in an aqueous medium, and are pharmaceutically-acceptable. The oligomers are useful for the treatment and/or diagnosis of AIDS and ARC.

Abstract: Certain triphenylpiperidines reverse drug resistance in multi-drug resistant tumors. These compounds apparently function by inhibiting a p-glycoprotein pump which becomes activated in late stage tumor development and which is inherently present in tumors from certain origins.

Abstract: The oligomers of the present invention are polyesters having a number average molecular weight of <10,000.
