Metabolic activation of the tetrahydro-thienopyridine antithrombotic prodrug, prasugrel, involves two steps: an esterase-dependent hydrolysis of its acetate function leading to thiolactone 6 and a cytochrome P450 (P450)-catalyzed oxidative cleavage of this thiolactone. This article shows that this second step involves
