Tetrahydroamentoflavone (THA) from Semecarpus anacardium as a potent inhibitor of xanthine oxidase.[Pubmed:20965242]
J Ethnopharmacol. 2011 Feb 16;133(3):1117-20.
ETHNOPHARMACOLOGICAL RELEVANCE: Seed of Semecarpus anacardium L. is widely used in Indian traditional medicine; Ayurveda and Sidha, for treatment of inflammatory disorders and gout. AIM OF THE STUDY: The present study was aimed at isolation of a compound for its potential to inhibit xanthine oxidase (XO), over expression of which lead to inflammation and gout. MATERIALS AND METHODS: Activity guided fractionation of S. anacardium seed was conducted using liquid-liquid partition and preparative HPLC. The fractions were evaluated for their XO inhibition and antioxidant activity. The ethyl acetate fraction with the highest XO activity yielded a biflavonoid compound Tetrahydroamentoflavone (THA). Lineweaver-Burk (LB) plot for the XO inhibition of THA and allopurinol was constructed from the kinetic data. RESULTS: IC(5)(0) values of THA and allopurinol for XO inhibition were 92 and 100 nM respectively and their corresponding values for K(i) were 0.982 and 0.612 muM respectively. CONCLUSION: THA was a potent XO inhibitor which could be considered as a drug candidate or chemopreventive agent, after establishing its pharmacological and clinical evaluation. The study results appear to support the claim of the traditional medicine with respect to the efficacy of S. anacardium seed against inflammation and gout.
A cyclooxygenase (COX) inhibitory biflavonoid from the seeds of Semecarpus anacardium.[Pubmed:15507338]
J Ethnopharmacol. 2004 Dec;95(2-3):209-12.
Semecarpus anacardium Linn., Anacardiaceae, is being most commonly used in India for the treatment of rheumatoid arthritis and other inflammatory disorders. Bioactivity guided fractionation of ethyl acetate extract led to the isolation of major active principle, Tetrahydroamentoflavone (THA), a biflavonoid. The in vitro cyclooxygenase (COX-1) catalyzed prostaglandin biosynthesis assay of THA gave an IC(50) value of 29.5 microM (COX-1) and 40.5% inhibition at 100 microg/mL (COX-2). The in vivo carrageenan induced paw edema assay resulted in dose dependent anti-inflammatory effect of THA and the activity was comparable to that of ibuprofen, one of the well known NSAIDs.
