Abstract: | Increased oxidative stress has been implicated in the pathogenesis of dopaminergic neurodegeneration leading to the development of Parkinson's disease. In this study, we investigated whether naphtha1,2-d]thiazol-2-amine (NTA) may ameliorate haloperidol-induced catalepsy and oxidative damage in mice brain. Haloperidol-induced catalepsy was measured with the standard bar test. The extent of oxidative stress has been evaluated by measuring levels of MDA, GSH and activities of antioxidant enzymes (SOD and GSH-Px) from brain homogenate. Haloperidol treatment significantly induced the catalepsy as observed from increased descent time measured in the bar test. Pretreatment with NTA significantly reduced the catalepsy induced by haloperidol in a dose-dependent manner. The elevated level of MDA in haloperidol-treated mice was significantly decreased by NTA pretreatment. The decreased level of GSH as well as SOD and GSH-Px activities in haloperidol-treated mice were significantly increased by NTA pretreatment. NTA reduces the oxidative stress allowing recovery of detoxifying enzyme activities and controlling free radical production, suggesting a potential role of the drug as an alternative/adjuvant drug in preventing and treating the neurodegenerative diseases, such as Parkinson's disease. |
