One-Pot Synthesis of a New Imidazole-5-Carboxylic Acid Derivative via Heterocyclization Reaction

From few decades, fused heterocyclic chemistry has occupied a prominent place in Medicinal Chemistry. Moreover, fused imidazole systems have attracted the researcher’s interest due to their natural occurrence and significant medicinal applications [1-3]. Additionally, the benzimidazole derivatives are the bioisosters of natural nucleotides, which can interact easily with the macromolecules (proteins, enzymes and receptors) of the biological system, has made the benzimidazole and its derivatives as the privileged pharmacophore in drug discovery process [4,5]. They are able to produce anti-inflammatory [6], antibacterial [7], anti cancer [8], analgesic [9], antiviral [10] and anticonvulsant [11] activitie, etc., Further benzimidazoles also can act as inhibitors for α-Glucosidase [12], Cyclooxygenase [13], Poly (ADP-ribose) polymerase [14] and lysophosphatidic acid acyltransferase-β [15]. Interestingly, benzimidazoles are also being incorporated into various commercially available drugs [16,17]. This vast applicability and usefulness of the fused imidazole nucleus inspired us to design and develop the target molecule.
