Polydatin as a potential therapeutic agent for migraine: mechanistic insights from experimental, network pharmacology and molecular docking studies
Abstract
Abstract Background Migraine is a neurological disorder and major cause of disability globally, especially in women and young adults. This study aimed to investigate the beneficial effects of polydatin (PD), a natural compound, against nitroglycerin (NTG) induced migraine like headache in mice. Materials and methods Behavioural paradigms included Von Frey filament test, tail flick test, light aversion test and assessment of migraine-associated pain like behaviour. In addition, biochemical investigations were undertaken to determine the effect of PD on migraine associated markers including oxidative stress, nitric oxide (NO) and calcitonin gene related peptide (CGRP). Integrated in vivo, in silico, and network pharmacology approaches were employed to evaluate PD’s antimigraine effects. Statistical significance was set at p < 0.05. Results Treatment with PD attenuated NTG-induced migraine like headache and related behavioural changes. PD-subjected animals exhibited enhanced levels of catalase, glutathione-S-transferase, and glutathione, as well as reduced lipid peroxidation, compared to NTG-only treated animals. Reduction in CGRP and nitrite levels along with reduced expression of neuronal nitric oxide synthase (nNOS) and inducible nitric oxide synthase (iNOS) was also observed in mouse cortex and trigeminal nucleus caudalis (TNc) after treatment with PD compared with disease controls. Histological sections from PD treated animals from these regions resembled closely with…
