Sulfone derivatives with anti-HIV activity.
Following the discovery of anti-HIV properties of suramin great efforts were devoted to design novel NNRT agents with the aims to find novel drugs for the clinical therapeutic management of AIDS. Sulfone and sulfonamide derivatives were studied by NCI at Bethesda as potential anti-HIV-1 agents and nitrophenyl phenyl sulfone (NPPS) was selected as lead compound for further investigations. At the same time Merck Laboratories discovered L-737,126, a potent indolyl aryl sulfone with inhibitory activity against reverse transcriptase. These studies stimulated novel search in the sulfone series and both diarylsulfones and cyclic sulfone derivatives were investigated. Our decennial interest in chemotherapeutic agents containing a pyrrole ring pulsed us to synthesize and test as anti-HIV-1 agents a number of pyrryl aryl sulfones (PASs), pyrrolobenzothiadiazepine (PBTDs) and pyrrolobenzothiazepine related sulfones. The new sulfone derivatives inhibit selectively HIV-1 and were inactive against HIV-2. Most of them were as active as, if not more active than, nevirapine.
