Abstract S-Nitrosothiols have been implicated to play key roles in a variety of physiological processes. The potential physiological importance of S-nitrosothiols prompted us to examine their reaction with thiols. We find that S-nitrosothiols can react with thiols to generate nitroxyl (HNO) and the corresponding disulfide. Further reaction of HNO with the remaining S-nitrosothiol and thiol results in the generation of other species including NO, sulfinamide, and hydroxylamine. Mechanisms are proposed that rationalize the observed products.
