Design, Synthesis and Pharmacological Evaluation of Novel Annelated Pyrimido[2,1-<em>c</em>][1,2,4]Triazolo[3,4-<em>f</em>][1,2,4]Triazines as Antimicrobial Agents

Abstract

In our tactic to construct bio-active molecules, a series of novel pyrimido[2,1-c][1,2,4]triazine-3,4-diones based heterocycles, were synthesized and evaluated for their in vitro antimicrobial impacts. The exploratory bioassay results declared that, the majority of the evaluated compounds exhibited considerable anti-microbial activity comparable to the reference drugs. Conjugates 15j, 15f, 15i, 15h, 15g and 15a were found to be the most potent antibacterial, indicating that conjugates bearing electron-attracting substituents exhibited higher potency than these with electron-releasing substituents.
