Abstract
Inflammation is a complex biological response involving immune cells to an infection creating injury to the normal tissues. The anti-inflammatory efficacy of embelin, a benzoquinone from the plant Embelia ribes, was screened for antioxidant and anti-inflammatory activity in carrageenan and Freund's adjuvant-induced inflammation models. Embelin exhibited significant dose-dependent antioxidant potential. In carrageenan-induced inflammation, embelin (20mg/kg) showed an inhibition of oedema by 71.01 ± 0.12% and 81.91 ± 0.67% in Freund's adjuvant-treated chronic inflammation model and resulted in a noticeable increase in adrenal size and restoration of the weight of spleen. Embelin also demonstrated cytoprotective effects on HEK-293 cells under induced oxidative stress. In silico analysis, embelin demonstrated binding energy of - 7.7kcal/Mol and - 7.0kcal/Mol with COX1 and COX2 with two hydrogen bonds. These results further prove that embelin could be a promising anti-inflammatory agent and supports the traditional use of Embelia ribes for rheumatism.
