Pyridine Scaffolds, Phenols and Derivatives of Azo Moiety: Current Therapeutic Perspectives

Synthetic heterocyclic compounds have incredible potential against different diseases; pyridines, phenolic compounds and the derivatives of azo moiety have shown excellent antimicrobial, antiviral, antidiabetic, anti-melanogenic, anti-ulcer, anticancer, anti-mycobacterial, anti-inflammatory, DNA binding and chemosensing activities. In the present review, the above-mentioned activities of the nitrogen-containing heterocyclic compounds (pyridines), hydroxyl (phenols) and azo derivatives are discussed with reference to the minimum inhibitory concentration and structure-activity relationship, which clearly indicate that the presence of nitrogen in the phenyl ring; in addition, the hydroxyl substituent and the incorporation of a diazo group is crucial for the improved efficacies of the compounds in probing different diseases. The comparison was made with the reported drugs and new synthetic derivatives that showed recent therapeutic perspectives made in the last five years.

Automated summary

Synthetic heterocyclic compounds show great potential in fighting various diseases, with pyridines, phenolic compounds, and azo derivatives displaying excellent antimicrobial, antiviral, and other activities. The presence of nitrogen in the phenyl ring, hydroxyl substituents, and incorporation of a diazo group are crucial for the compounds' efficacy. Recent studies compared these compounds with existing drugs and new synthetic derivatives to explore therapeutic possibilities.
