Product ID: AL-005 Category:


(S)-(+)-Clopidogrel is a prodrug that is metabolized by cytochrome P450 isoforms to produce an active metabolite, which is a selective, irreversible high-affinity antagonist of the platelet purinergic P2Y12 receptor. Potent antithrombotic antiplatelet agent. By inhibiting the Purinoceptor P2Y12 subtype it consequently inhibits ADP-induced platelet aggregation. (S)-(+)-Clopidogrel hydrogen sulfate is the active isomer. Compound can be used as analytical reference material.
