A metabolite of Nabumetone. A competitive, non-selective COX inhibitor.
ChEBI: (6-methoxy-2-naphthyl)acetic acid is a monocarboxylic acid consisting of 2-naphthylacetic acid having a methoxy substituent at the 6-position. The active metabolite of the prodrug nabumetone. It has a role as an EC 1.14.99.1 (prostaglandin-endoperoxide synthase) inhibitor, a drug metabolite and a xenobiotic metabolite. It is a monocarboxylic acid and a methoxynaphthalene. It is functionally related to a 2-naphthylacetic acid.
6-methoxy naphthalene acetic acid is a competitive and non-selective cox inhibitor with ki values of 21 and 19 μm for ovine cox-1 and -2, respectively [1][2][3].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].6-methoxy naphthalene acetic acid (6-mna) is a competitive and non-selective cox inhibitor with ki values of 21 and 19 μm for ovine cox-1 and -2, respectively [1][2]. 6-mna is a metabolite of nebumetome. 6-mna inhibited human recombinant cox-1 and -2 with ic50 values of 70 and 20 μm, respectively [1].
