Integrating in vivo and in silico approaches to investigate the potential of Zingiber roseum rhizome extract against pyrexia, inflammation and pain.

Abstract

Zingiber roseum is a perennial herb in the Zingiberaceae family. The plant is native to Bangladesh, and rhizomes are frequently used in traditional medicine to cure gastric ulcers, asthma, wounds, and rheumatic disorders. Therefore, the present study aimed to analyse the antipyretic, anti-inflammatory, and analgesic properties of Z. roseum rhizome to confirm its efficacy in traditional applications. After 24 h of treatment, ZrrME (400 mg/kg) showed a considerable drop in rectal temperature (3.42°F) compared to standard paracetamol (5.26°F). At both doses (200 and 400 mg/kg), ZrrME showed a substantial dose-dependent decrease in paw oedema. However, after 2, 3 and 4 h of testing, the extract (200 mg/kg) had a lower anti-inflammatory response than standard indomethacin, whereas the higher dose (400 mg/kg) of rhizome extract had a more robust response compared to standard. ZrrME also showed substantial analgesic activity against all in vivo analgesic test models. The in vivo findings were further evaluated by in silico study of our previously identified compounds of ZrrME with the cyclooxygenase-2 enzyme (3LN1). The substantial binding energy (ranges from-6.2 to-7.7 Kcal/mol) of the polyphenols (excluding catechin hydrate) to the COX-2 enzyme affirm the in vivo test results of the present studies. In addition, the compounds were found effective as antipyretic, anti-inflammatory, and analgesic agents, according to the biological activity prediction software. Both in vivo and in silico results demonstrated promising antipyretic, anti-inflammatory, and pain-relieving effects of Z. roseum rhizome extract, which corroborate the claim of its traditional uses.
