Synthesis, molecular modeling and harnessing the antimicrobial activity of new pyrazine-thiadiazole hybrids.

ABSTRACT: Various pyrazine-substituted thiadiazole hybrid compounds 5a-c, 9a-c, and 11a-c have been synthesized and elucidated using spectral measurements. Despite the alternative spatial structures, the DFT modeling of the targeting hybrids revealed comparable HOMO-LUMO configurations and energies, which were employed in the estimation of some chemical reactivity parameters. Further, the antimicrobial efficacy of these hybrids was measured against bacterial and fungal strains. Hybrids 5b, 5c, and 9c demonstrated effective antimicrobial activities, comparable to reference drugs. Hybrid 5b exhibited broad-spectrum activity, while 9c showed the strongest antifungal effectiveness. Moreover, in vitro assessment of dihydrofolate reductase (DHFR) enzyme inhibition revealed notable activity; hybrid 9c demo
