Abstract

Mangosteen fruit has been used for various disorders, including pain. The effects of alpha-mangostin, the main component of mangosteen, on the neuropathic pain caused by chronic constriction injury (CCI) were evaluated in rats. In treatment groups, alpha-mangostin (10, 50, 100 mg/kg/day, i.p.) was administered from Day 0, the day of surgery, for 14 days. The degree of heat hyperalgesia, cold, and mechanical allodynia was assessed on Days 0, 3, 5, 7, 10, and 14. The lumbar spinal cord levels of MDA, GSH, inflammatory markers (TLR-4, TNF-α, MMP2, COX2, IL-1β, iNOS, and NO), apoptotic markers (Bcl-2, Bax, and caspase-3) were measured by western blot on Days 7 and 14. Rats in the CCI group showed thermal hyperalgesia, cold, and mechanical allodynia on Days 3-14. All concentrations of alpha-mangostin alleviated CCI-induced behavioral alterations. MDA level augmented and GSH level decreased in the CCI group and alpha-mangostin (50, 100 mg/kg) reversed the alterations. An enhancement in the levels of all inflammatory markers, Bax, and caspase-3 was shown on Days 7 and 14, which was controlled by alpha-mangostin (50 mg/kg). The detected antinociceptive effects of alpha-mangostin may be mediated through antioxidant, anti-inflammatory, and antiapoptotic properties.
