p-Hydroxycinnamic acid (p-Coumaric acid), is a ubiquitous plant metabolite with antioxidant and anti-inflammatory properties. p-Hydroxycinnamic acid (500 μM and 1 mM) reduces ADP-induced platelet aggregation (55•2 (SE 4•01) % and 35•6 (SE 2•35) % relative to basal level, respectively). p-Hydroxycinnamic acid is able to modify platelet function, a shear-inducing device that simulates primary haemostasis. p-Hydroxycinnamic acid interferes also with arachidonic acid cascade, reducing thromboxane B 2 production and lipopolysaccharide-induced prostaglandin E 2 generation (IC 50 371 and 126 μM, respectively).
