Valeryl salicylate is a selective inhibitor of Cox-1.
ChEBI: A valerate ester that is salicylic acid in which the phenolic hydrogen is replaced by a valeryl (pentanoyl) group.
valeroyl salicylate is an irreversible and selective inhibitor of cyclooxygenase-1 (cox-1) with ic50 values of 0.8 and 15 mm for ovine cox-1 and -2, respectively [1].cyclooxygenase (cox), also known as prostaglandin-endoperoxide synthase (ptgs, pghs), is an enzyme responsible for formation of prostanoids, including thromboxane and prostaglandins such as prostacyclin. cox-1 is the constitutive isoform and is mainly responsible for the synthesis of cytoprotective prostaglandins in the gastrointestinal tract (gi) and of the proaggregatory thromboxane in blood platelets. cox-2 is inducible and short-lived that is stimulated by endotoxin, cytokines, and mitogens. cox-2 plays important roles in prostaglandin biosynthesis in inflammatory cells the central nervous system [1][2].valeroyl salicylate is an irreversible and selective inhibitor of cyclooxygenase-1 (cox-1) with ic50 values of 0.8 and 15 mm for ovine cox-1 and -2, respectively. in cos-1 cells expressing either cox-1 or -2, 500 μm of valeroyl salicylate inhibited human cox-1 and -2 by 85% and 15%, respectively. the half-lives for inactivation of human recombinant cox-1 in the presence of 500 μm valeroyl salicylate was 12 minutes [2].
