As part of our research on substituted benzimidazoles, we are interested in the synthesis of new heterocyclic molecules. This new organic molecule is a subclass of quinolines with a wide variety of biological properties. In order to affect the binding of quinoline to our bis-benzimidazole derivatives, we have chosen the "azo" bond as a means of attachment. To achieve our goal, we investigated different parameters for the reactions to determine the conditions to obtain the best results. This article discusses the antioxidant activity of our molecules using the DPPH method.
