FR-188582 is a potent and selective inhibitor of thromboxane A₂ synthase (TXS). It is primarily used in pharmacological research for its antithrombotic effects, including inhibition of platelet aggregation and vasoconstriction mediated by thromboxane A₂. Key applications include studies on thrombosis prevention, cardiovascular diseases, and renal protection in ischemia-reperfusion models. Its high specificity makes it valuable in preclinical drug development.
