    摘要: This invention pertains to the discovery that condensation polymers of an aldehyde and aromatic sulfonic acids and fractions thereof, such as formaldehyde naphthalenesulfonic acid condensation polymers, can abrogate HIV gp120 binding to CD4, as demonstrated in CD4/gp120 binding assays. In addition to gp120 binding inhibition, the compounds have been shown to inhibit HIV-induced syncytia formation and infectivity of CD+ cells. The use of this compound has been shown to be non-cytotoxic and non-inhibitory to antigen induced T lymphocyte proliferation. Based on these findings, these compounds can be used as a therapeutic agent for the treatment of acquired immunodeficiency syndrome (AIDS), as well as AIDS-related complex (ARC), AIDS-related dementia and non-symptomatic HIV infection. The compounds can also be used to treat blood preparations.

    摘要: The present invention is a method of protecting a sulfonic acid functional group in an organic molecule as a substituted or unsubstituted neopentyl sulfonate ester. The method allows the conversion of R--SO.sub.3 --H to R'--SO.sub.3 --H, wherein R and R' are different organic radicals. Also disclosed is a method of increasing the bioavailability of drugs with a sulfonic acid functional group by protecting the sulfonic acid functional group as a substituted neopentyl sulfonate ester which has a masked heteroatom nucleophile. The masked nucleophile can be liberated in vivo, resulting in removal of the neopentyl protecting group and regeneration of the parent drug.
