Benzimidazole is a benzo derivative of imidazole. It is a kind of bicyclic aromatic organic compounds, which is formed by fusing a six-membered benzene ring and five-membered imidazole at positions 4 and 5 of imidazole ring. It is an important pharmacophore of many biologically active heterocyclic compounds with various pharmacological activities. Benzimidazoles and their derivatives have developed into dynamic heterocyclic systems due to their potency in a variety of biologically active compounds such as anticancer, bactericidal and antiviral drugs. Benzimidazoles are a class of therapeutic motifs with broad relevance in medicinal chemistry.
Benzofurazans are important pharmaceutical intermediates. Benzofurazans are known bioisosteres of the nitro group. Both oxadiazoles and nitro groups have strong electron-withdrawing properties, but when optimizing drug-like properties such as activity, selectivity, and stability, the absence of standard charges in the oxadiazole structure may be more beneficial to drug products. What's more, nitro groups have been identified as toxic groups, and it is routine to remove or replace them in the early stages of drug development.
