3-Mercaptopyruvic acid is an intermediate in cysteine metabolism. It has been studied as a potential treatment for cyanide poisoning, but its half-life is too short for it to be clinically effective.[1] Instead, prodrugs, such as sulfanegen, are being evaluated to compensate for the short half-life of 3-mercaptopyruvic acid.[2]
