Author Description

The present investigation comprises a survey covering the antioxidant activities of compounds containing the oxadiazole, thiadiazole and triazole ring system, with particular reference to benzimidazole and indole derivatives. In this work, 34 intermediates and 128 new compounds derived from indole and benzimidazole were synthesized. The structures of new compounds were confirmed by both analytical and spectral data (IR, NMR and MS). The antioxidant activities were tested in vitro using DPPH radical scavenging assay.
