Malignant glioma is the deadliest form of brain cancer. Zingerone (ZO), a polyphenolic compound found in ginger, offers pharmacological properties that make it a promising agent for containing the growth of glioma cells. The present study was conducted to understand the efficacy of ZO in containing the growth of C6 glioma cells. The study also assessed the prophylactic role of ZO on rat brain glioma induced by C6 cell lines by addressing its antioxidative action on biochemical, behavioral, and histoarchitectural indices. For dose optimization, the animals were pretreated with different doses of ZO for a period of 2 weeks before the inoculation of glioma cells (1 × 10 5 /10 µL phosphate-buffered saline) in the caudate region of rat brain and the treatment with ZO continued for 4 more weeks post implantation. In vitro studies were done to assess the radical scavenging activity of ZO and also to determine its effects on viability of C6 glioma cells at different concentrations. Glioma-bearing rats showed significant alterations in memory; exploratory and muscular activities which were appreciably improved upon simultaneous supplementation of ZO administered at a dose of 50 mg/kg body weight and were also visible even at a higher dose. Glioma-bearing rats revealed a significant increase in reactive oxygen species, protein carbonyl contents, and lipid peroxidation, but showed a significant decrease in reduced glutathione and antioxidative enzymes in the brain tissue. Interestingly, all the biochemical indices and altered brain histoarchitecture displaying cellular atypia and hyperplasia showed appreciable improvement when supplemented with ZO at a dose of 50 mg/kg body weight.
