    Abstract:
    The clinical applications of benzodiazepines as anxiolytics are limited because of their unwanted side effects. Therefore, the development of new pharmacological agents is well justified. Eight variably substituted chalcones were investigated for their effects on central nervous system if they have anxiolytic effects in rats. Anxiolytic effects of chalcones were also compared with standard anxiolytic drug (diazepam, DZP). Rats were injected intraperitoneally with chalcones, their derivatives and DZP for 3 days. Chalcones and their derivatives were injected at the dose of 25 mg/kg body weight and DZP was injected at the dose of 1 and 2 mg/kg body weight. Rats were then subjected to various anxiety paradigms including the open field behaviour and elevated plus maze tests. In addition, their effects on rota rod performance and grip strength were also examined. Variably substituted chalcones and DZP showed differential pattern of activities.
