| 1 | First isolation of glutinol and a bioactive fraction with good antiinflammatory activity from n-hexane fraction of Peltophorum africanum leaf显示文摘Objective: To investigate the anti-inflammatory activity of different fractions and glutinol(isolated compound),using nitric oxide synthase and cyclooxygenase(COX) inhibition as an indication of anti-inflammatory activity,Methods: Anti-inflammatory activity was evaluated using an in vitro assay determining the inhibition of the activity of pro-inflammatory enzyme model,Cyclooxygenases and inducible nitric oxide synthase are crucial enzymes involved in the pathogenesis of many chronic inflammatory conditions,Results: Sub-fraction F3.3 that was derived from n-hexane fraction of PA leaves significantly inhibited(P = 0.01) the catalytic activity of COX-2(IC50 = 0.67 μg/m L) better than isolated compound,glutinol(IC50 = 1.22 μg/m L),compound 2(CP2)(IC50 = 1.71 μg/m L) and sub-fraction F3.3.0(IC50 = 1.30 μg/m L),A similar trend was observed in investigation of the inhibition of nitric oxide synthesis in RAW 264.7 cells by F3.3,glutinol,CP2 and F3.3.0,Inducible COX-2 and inducible nitric oxide synthase are among potent signalling enzymes that exacerbate inflammation,Conclusions: Bioactive sub-fractions(F3.3 and F3.3.0) derived from the n-hexane fraction of PA had good anti-inflammatory activity,and the isolated compound,and glutinol may be useful as a template for the development of new anti-inflammatory drugs. | Salmon A Adebayo Leshweni J Shai Jacobus N Eloff | 2017 | Asian Pacific Journal of Tropical Medicine2017，10，1： | 2 |
