Abstrakt: Back ground: 7-Methoxycoumarin (7-MC) is well recognized for its anti-inflammatory and anti-nociceptive actions. Its capacity to lessen neuropathic pain hasn't been documented yet. Hence the impact of 7-MC on vincristine-induced peripheral neuropathic pain in rodents was investigated. The investigation also looked at the impact of 7-MC in reducing neuropathic pain via voltage-gated calcium channels and phospholipase enzyme inhibition using pertinent in vitro and in silico methods. Methods and results: Vincristine (0.1 mg/kg, i.p., daily) was administered continuously for 7 days to induce peripheral neuropathic pain in mice, with cold allodynia and thermal hyperalgesia and evaluated on the 8th day using the acetone bubble test and hot water tail immersion test. In order to derive the mechanistic approach for ameliorating neuropathic pain, the role of 7-MC in the inhibition of the phospholipase enzyme, gene expression studies on voltage-gated calcium channels using mouse BV2 microglial cells and in silico studies for its calcium channel binding affinity were also performed. The test compounds reduced vincristine-induced cold allodynia and thermal hyperalgesia in mice in a dose-dependent experiments. In vitro studies on phospholipase inhibition by 7-MC showed an IC50 of 27.08 µg/ml and down-regulated the gene expression of calcium channels in the BV2 microglial cell line. In silico docking scores for 7-MCwere higher than the standard drug gabapentin. Conclusion: The compound 7-MC has shown promise in alleviating vincristine-induced peripheral neuropathicin mice. Studies conducted in parallel, both in silico and in vitro have demonstrated that 7-MC effectively reduces neuropathic pain. This pain reduction is achieved through two mechanisms: inhibiting the phospholipase enzyme and blocking voltage-gated calcium channels. [ABSTRACT FROM AUTHOR]
