ABSTRACT
The present study was designed to investigate the anti-inflammatory potential of Amycolatopsis thermoflava producing 1-O-methyl chrysophanol (OMC), a member of the hydroxyanthraquinone family. The anti-inflammatory potential was evaluated initially through in silico analysis against tumor necrosis factor- α and cyclooxygenase-2. The same activity was further confirmed based on the in vitro protein denaturation method as well as in vivo by a carrageenan-induced paw edema model in rats. The OMC compound was isolated, purified, and characterized from the fermentation broth of Amycoloptosis thermoflava. In vitro data revealed that the OMC possesses significant protein denaturation properties with an IC50 of 63.50±2.19 µg/ml higher than the standard drug, with an IC50 value of 71.42±0.715 µg/ml. The percentage of inhibition in paw swelling was observed to be 40.03±5.5 in OMC-treated group, which is comparable to the standard group (52.8±4.7). The histopathological evaluation and immunohistochemistry revealed the anti-inflammatory potential of OMC.
