Evaluation of the anti-inflammatory and urotoxicity ameliorative effects of γ-humulene containing active fraction of Emilia sonchifolia (L.) DC.

AbstractIn folklore medicine, the plantEmilia sonchifolia, belonging to the family Asteraceae, is used for treating tumour and inflammation. In our previous studies, we have done a thorough phytochemical investigation ofE. sonchifolia with a report on its potent antimetastatic activity. Further, we isolated and characterised its active fraction (AFES) containing the major compound γ-humulene with an evaluation of the antiangiogenic effect of AFES (5 mg/kg b.wt.). In the first part of the present study, AFES in different concentrations was used for the assessment of its possible anti-inflammatory effect employing three in vivo inflammatory models. Further using the most eff ective concentration of AFES 5 mg/kg b.wt, its effect on proinflammatory cytokine levels was recorded along with a confirmatory gene expression analysis. The results manifested with a reduction in the paw oedema significantly decreased levels of proinflammatory cytokines, C-reactive protein, nitri c oxide and also there was an efficient downregulation of cyclooxygenase-2 and inducible nitric oxide. Urotoxicity is one of the major side effects of conventional chemotherapy. So in the second part of the study, we used AFES in combination with the conventional therapeutic agent cyclophosphamide i n vivo in mice. The effect of AFES on urotoxicity was assessed from various biochemical parameters, cytokine markers and finally with a histopathology of the bladder. The current study revealed the protective effe...
