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.
本发明优选的低聚物是平均分子量小于 10,000 的聚
脲、聚
碳酸酯、聚酯或聚酰胺。这些低聚物可溶于
水,具有硬质骨架,具有通过羰基连接分子耦合的重复单元,这些单元具有阴离子基团,在
水介质中主要呈线性分布,使阴离子基团之间存在规则的间距,并且可药用。这些低聚物可用于治疗和/或诊断艾滋病和 ARC。
