A new mechanism of action of thienopyridine antiplatelet drugs - A role for gastric nitrosthiol metabolism?

Thienopyridine-SNO (an S-nitrosothiol molecule) would have the potential to participate in all the reactions expected of native nitric oxide (NO) with added benefit that the NO “moiety” is protected, transportable and largely preserved from further reactive metabolism. All these biochemical steps are present in humans and could occur prior to enzymatic biotransformation.
