Optical Activity UNSPECIFIED

Clopidogrel is first activated to its thiolactone intermediate, 2-oxo-clopidogrel via CYP3A oxidation. 2-oxo-clopidogrel is a key intermediate metabolite from which the active metabolite is formed. 2-oxo-clopidogrel inhibited the activity of CYP2C19 and moderately activity of CYP2B6.
