Sulfanegen is an experimental antidote for cyanide poisoning.[1] It is being studied as a prodrug for 3-mercaptopyruvic acid (3-MP). 3-MP has been studied as a potential treatment for cyanide poisoning, but the half-life is too short for it to be clinically effective.[2] Instead, prodrugs such as sulfanegen are being evaluated to compensate for the short half-life.[3]

Sulfanegen has been shown to be effective in animal studies.[4] It is being studied as the sodium salt, sulfanegen sodium, and the triethanolamine salt, sulfanegen TEA.[5][3]

One advantage sulfanegen may have over existing treatments for cyanide poisoning is that it might be administered by intramuscular injection rather than by intravenous infusion.[6]
