Triphala is an Ayurvedic herbal formulation consisting of equal parts of three myrobalans: Terminalia chebula, Terminalia bellerica and Emblica officinalis. We recently reported that chebulagic acid (CA) isolated from Terminalia chebula is a potent COX-2/5-LOX dual inhibitor. In this study, compounds isolated from Terminalia bellerica were tested for(More)
The antiproliferative effects of 15-LOX (15-lipoxygenase) metabolites of arachidonic acid {(15S)-HPETE [(15S)-hydroperoxyeicosatetraenoic acid] and (15S)-HETE [(15S)-hydroxyeicosatetraenoic acid]} and the mechanism(s) involved were studied in the human T-cell leukaemia cell line Jurkat. (15S)-HPETE, the hydroperoxy metabolite of 15-LOX, inhibited the growth(More)
Bioassay-guided fraction of the methanol extract of the roots of Pueraria tuberose DC yielded puerarin, an isoflavone C-glycoside (PT-1), isoorientin, a flavone C-glycoside (PT-2) and mangiferin, a xanthone C-glycoside (PT-3). The extracts and the isolated compounds were screened for potent anti-inflammatory components inhibiting the cyclooxygenases (COX-1(More)
Recent reports have demonstrated the role of phyto-constituents in modulating inflammatory responses. Mangiferin isolated from Mangifera indica is known to induce potent anti-oxidative, anti-diabetic and anti-inflammatory activity. However, the molecular mechanism of its anti-inflammatory activity is not properly understood. In this study we have isolated(More)
High-throughput screening (HTS) involves testing of compound libraries against validated drug targets using quantitative bioassays to identify 'hit' molecules that modulate the activity of target, which forms the starting point of a drug discovery effort. Eicosanoids formed via cyclooxygenase (COX) and lipoxygenase (LOX) pathways are major players in(More)
C-Glycosyl flavones are present in different plant tissues and they exhibit health benefits. In the present study, it was found that C-glycosyl flavones are distributed in different milled fractions of black gram and among these fractions, husk had the highest content of C-glycosyl flavones. Two C-glycosyl flavones from black gram husk were extracted and(More)
