Abstract:

Chronic pain remains a challenging clinical reality, yet currently available analgesics are insufficient to meet clinical needs. Increasing attention has been paid to bioactive compounds from natural plants, which may be efficacious against pain. This study examined the antinociceptive effects of isosakuranetin, a plant-derived transient receptor potential melastatin 3 blocker, in a rat model of peripheral neuropathy. Adult male Sprague-Dawley rats were first allowed to go through the chronic constriction injury surgery to develop neuropathic pain. They were then treated with isosakuranetin (1.5, 3, or 6 mg/kg) intraperitoneally and the effects on mechanical, thermal, and cold hyperalgesia were assessed using the von Frey filament test, Hargreaves' plantar test, and cold plate test, respectively. Isosakuranetin dose-dependently alleviated mechanical, thermal, and cold hyperalgesia and the antinociceptive potency was similar across the assays. In the rotarod test, isosakuranetin did not significantly affect motor performance within the doses tested, confirming the antinociceptive specificity. In summary, these findings suggest that isosakuranetin may be useful in treating neuropathic pain and deserves further investigation.
