Identification
Common Name2-Oxoclopidogrel
ClassSmall Molecule
Description2-Oxoclopidogrel is a thiolactone intermediate of clopidogrel, an antithrombotic prodrug (PMID: 23249383).. Hepatic cytochrome P450 (P450) enzymes catalyze the conversion of clopidogrel to 2-oxo-clopidogrel via CYP3A oxidation. After oxidation, 2-oxoclopidogrel is then subsequently hydrolyzed to the clopidogrel active metabolite known as CAM (PMID: 25970225). 2-oxoclopidogrel can form four isomers (H1, H2, H3 and H4) of CAM, in which H4 only found in humans. The H4 isomer exhibits twice the activity of the H2 isomer (PMID: 28602635). The H4 isomer blocks adenosine diphosphate (ADP) binding to the P2Y12 receptor which thereby inhibits ADP induced platelet aggregation. 2-oxoclopidogrel is only found in individuals that have used or taken Clopidogrel.
