Synthesis of pyrazole tethered oxadiazole and their analogs as potent antioxidant agents

Abstract

AbstractPreparation of organic compounds in environmental favor media always a fresh tool in the synthetic research. If those prepared compounds may possess therapeutically potentiality, then it called as efficient research. Herein, we report the 12 new oxadiazole linked carboxamide pyrazole substances have been synthesized and screened for their free radical scavenging activity by using hydrogen peroxide (H2O2), nitric oxide (N2O), and diphenyl picryl hydrazide (DPPH) methods. All the compounds displayed reliable biological properties. Among them, compound 8f hold high antioxidant activity may be due to the presence of methoxy group at para position of benzene ring. From the synthetic point of view, this is the novel environment favor method for the synthesis of pyrazole linked oxadiazoles, and the biological results of these compounds may stand as a referee for further development of biologically active pyrazole tethered oxadiazoles.
