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.

Identification of the human cytochrome P450 enzymes involved in the two oxidative steps in the bioactivation of clopidogrel to its pharmacologically active metabolite.
2010 Jan
Cytochromes P450 catalyze both steps of the major pathway of clopidogrel bioactivation, whereas paraoxonase catalyzes the formation of a minor thiol metabolite isomer.
