Hydrogen sulfide (HS) is an endogenously produced signaling molecule. The enzymes 3-mercaptopyruvate sulfurtransferase (MST), partly localized in mitochondria, and the inner mitochondrial membrane-associated sulfide:quinone oxidoreductase (SQR), besides being respectively involved in the synthesis and catabolism of HS, generate sulfane sulfur species such as persulfides and polysulfides, currently recognized as mediating some of the HS biological effects. Reprogramming of HS metabolism was reported to support cellular proliferation and energy metabolism in cancer cells.

Biosynthesis of hydrogen sulfide (HS), a key signalling molecule in human (patho)physiology, is mostly accomplished by the human enzymes cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (MST). Several lines of evidence have shown a close correlation between increased HS production and human diseases, such as several cancer types and amyotrophic lateral sclerosis. Identifying compounds selectively and potently inhibiting the human HS-synthesizing enzymes may therefore prove beneficial for pharmacological applications.
