Abstract
AIMS: This study is aimed at the evaluation of antipyretic effect of PHY in yeast-induced hyperthermia rats. Additionally, possible mechanism of antipyretic action of PHY has been also studied by molecular docking study. METHODS: Adult male Wistar albino rats were treated with PHY at 100, 150 and 200 mg/kg in 0.05% Tween-80 dissolved in 0.9% NaCl solution. PHY was also given at 200 mg/kg with ibuprofen (IBU) 12.5 mg/kg (p.o.) or paracetamol (PARA) 100 mg/kg (p.o.) to see the combined effect of PHY in animals. In silico study of PHY was performed against cyclooxygenase (COX) enzymes (COX-1 and -2) proteins. RESULTS: PHY exhibited the antipyretic effect in febrile rats in a dose and time dependent manner. PHY 200 mg/kg co-treated with IBU12.5 or PARA100 exhibited greater antipyretic effect than the PHY or NSAIDs individual groups. Data from the computational study reveal that 5KIR of COX-2 is the most efficient receptor protein to which PHY interacts. CONCLUSION: PHY attributed an antipyretic effect, possibly via 5KIR-dependent COX-2 inhibition pathway.
