Abstract
ABSTRACTObjective: The objective of this study is to evaluate and compare the free radical scavenging activities of selective dopamine agonist namely ropiniroleand pramipexole.Methods: The antioxidant activity of ropinirole and pramipexole at various concentrations was done by 1, 1-diphenyl-2picrylhydrazyl (DPPH) freeradical scavenging assay comparing it with ascorbic acid which was taken as standard.Results: The free radical scavenging property as measured by DPPH method showed that ropinirole and pramipexole have got a potent free radicalscavenging activity with that of ascorbic acid.Conclusion: Novel drugs such as pramipexole and ropinirole are promising molecules in the field of oxidative damage related neurodegenerativedisorders providing us an optimistic targeted approach toward neuroprotection.Keywords: Free radical scavenging, 1, 1-diphenyl-2picrylhydrazyl assay, Anti-Parkinson’s, Dopamine agonist.
