We present a study on a new class of Schiff bases with pyrimidine linked hydrazinyl azole backbone. These compounds were synthesized using conventional and ultrasonication methods. Our design strategy incorporated three heteroaromatic azoles and various substituents on the pyrimidine scaffold to enhance antimicrobial properties. Antibacterial and antifungal screenings were conducted against specific pathogens, and molecular docking studies supported the results. The compounds exhibited significant antimicrobial activities, particularly against K. pneumoniae, surpassing the standard drug. These Schiff bases hold promise as potential antimicrobial agents.

A new class of bis(azolyl) pyridine‐2,6‐dicarboxamides based derivatives were designed and synthesized by employing ultrasonication methodology. In this work, we studied the role of different heteroaromatic azole units such as oxazole, thiazole and imidazole moieties along with different donating/withdrawing substituents on the pyridine scaffold and anticipated to display good biological activities. The detailed molecular docking studies validates the antimicrobial activities of these targeted molecules. Further, to evaluate their antioxidant properties, the target compounds were exposed to three different invitro free radical scavenging assay methods. Further, using the disc diffusion method, the targeted molecules were screened for invitro antibacterial activities against the pathogenic stains. Besides, the targeted molecules were also tested against A. niger and P. chrysogenum strains to assess their antifungal activity. The screening results reveals that, the most of the compounds form the series demonstrating reasonable to decent antioxidant and antimicrobial activities against pathogenic stains in comparison with the standard drug.
