ABSTRACT:
The narrow poly- or mono-dispersed oligomers of the present invention are polyureas, polycarbonates, polyesters or polyamides having a recurring unit of from 3 to 50. These oligomers are water-soluble, preferably have a rigid backbone, have recurring units coupled by carbonyl linking moities which have anionic groups, display predominantly linear geometry such that regular spacing between anionic groups exists in an aqueous medium, and are pharmaceutically-acceptable. The narrow poly- or mono-dispersed oligomers are useful for the treatment and/or diagnosis of AIDS and/or ARC or HSV.
