Summary
S-Benzylglutathione is a synthetic tripeptide (γ-Glu-Cys(S-Bn)-Gly) derived from glutathione by S-benzylation of the cysteine thiol. It is a well-characterized biochemical tool compound used to study the glyoxalase system and glutathione S-transferases. It has shown antiproliferative activity in cancer cell lines and is explored as a lead structure for antitumor and antiparasitic agents, but has no approved clinical use.
Mechanism of Action
Competitive inhibitor of glyoxalase I (Glo1); binds the active site of Glo1 by mimicking the hemithioacetal substrate, blocking conversion of methylglyoxal to S-lactoylglutathione and thereby disrupting detoxification of reactive carbonyl species. Also inhibits certain glutathione S-transferases.
