p-Hydroxy-cinnamic acid

p-Hydroxy-cinnamic acid (CAS No.: 7400-08-0) is a naturally occurring hydroxycinnamic acid belonging to a class of phenolic compounds characterized by a hydroxylated aromatic ring, widely distributed in plant-derived materials and commonly studied for its biochemical and pharmacological properties in vitro. This compound has been reported to modulate platelet function and inflammatory mediator production, demonstrating inhibitory activity against thromboxane B2 synthesis and lipopolysaccharide-induced prostaglandin E2 generation at low to moderate micromolar concentrations, indicating potential interactions with cyclooxygenase-associated pathways and related signaling cascades. Its activity profile suggests utility as a biochemical probe for investigating mechanisms of platelet aggregation, eicosanoid biosynthesis, and inflammation-related signaling networks. In research settings, p-Hydroxy-cinnamic acid is frequently applied in cell-based assays and biochemical studies to evaluate phenolic compound-mediated modulation of oxidative and inflammatory responses, and it may serve as a reference molecule in compound screening and structure–activity relationship studies. Experimental concentrations and treatment regimens vary depending on the specific assay systems and research objectives.
