WebIrreversible cyclooxygenase inhibitors Aspirin (salicylate) Aspirin is the most commonly used antiplatelet agent. Aspirin irreversibly blocks the enzyme cyclooxygenase-1 enzyme and interrupts the first step in the prostaglandin and thromboxane A 2 synthesis pathway, thereby inhibiting platelet aggregation. WebMar 14, 2024 · The inhibition of cyclooxygenase activity by aspirin is due to its ability to chemically modify a serine residue (Ser530) of the enzyme. The serine residue acquires an acetyl group from aspirin, an irreversible modification. Thus, aspirin is an example of an irreversible inhibitor. There are actually two COX isozymes: a constitutive form, COX-1 ...
