N-(4-Chloro-3-((3-Methyl-2-Butenyl)Oxy)Phenyl)-2-Methyl-3-Furancarbothioamide (also known as UC-781) is a thiocarboxanilide non-nucleoside reverse transcriptase inhibitor patented by Uniroyal Chemical Company, Inc. for prevention of HIV transmission. UC-781 is a potent inhibitor of reverse transcriptase-dependent pyrophosphorolysis, and purportedly restores the chain-terminating activity of zidovudine (AZT) against AZT-resistant virus. In clinical trials single and 7-day topical rectal exposure of UC-781 was safe with no significant adverse events, no detected UC-781 plasma drug levels, no significant mucosal changes, and high participant acceptability. Ex vivo biopsy infections demonstrated marked suppression of HIV infectibility, identifying a potential early biomarker of efficacy.
