ABSTRACT:
Background: The study of free radicals nowadays have become more attention as these are evoked continuously due to hazardous environmental conditions and food habits. Endogenously free radicals are introduced in our body due to exposure to different physiochemical conditions or some pathological states by various mechanisms. Oxidative stress occurs due to exposure of excess free radicals to body. Antioxidants act as a major defence against the free radical-mediated injury by scavenging them. Majority of the flavonoids found in plant products are known as antioxidants as they selectively scavenge the free radicals. Methods: Synthetic flavones (VMF41, VMF 43, VMF 45 and VMF 46) having different side chains on the: 3-hydroxy-2- (5-methyl, 7-methyl, 6-methyl, and 7--methoxy) 2- thiophen-4H-chromen-4-one structure were examined for free radical scavenging potential over nitric oxide, hydroxyl, and superoxide anion radicals by using appropriate in-vitro assay methods. Results and Discussion: Overall, with few exceptions, all the synthetic flavonoids (SFs) exhibited moderate free radical scavenging activity as compared to the standard drug. The test samples in the study showed dose dependant activity of scavenging activity. In nitric oxide radial scavenging activity, test flavonoids VMF 45 and VMF 46 exhibited significant scavenging activity at 50- 100µg/ml concentrations. The SFs VMF 43 and VMF 46 showed a good scavenging activity for hydroxyl, nitric oxide radicals and compounds VMF41, and VMF 43 showed significant scavenging activity at 50 µg/ml to 100µg/ml concentrations for superoxide radicals. However all the SFs at 10µg/ml concentration showed the low or poor radical scavenging activity. Conclusion: It is clear that these synthetic flavonoids (SFs) can be considered as potential antioxidant agents, however needs to be further tested at in vivo experiment to consider them as a lead antioxidant drug candidates.
