A series of substituted triazole functionalized 2H-benzo[b][1,4]oxazin-3(4H)-ones were synthesized by employing click chemistry and further characterized based on ¹H NMR, ¹³C NMR, IR and mass spectral studies. All the synthesized derivatives were screened for their in vitro antimicrobial activities. Further, molecular docking studies were accomplished to explore the binding interactions between 1,2,3-triazol-4-yl-2H-benzo[b][1,4]oxazin-3(4H)-one and the active site of Staphylococcus aureus (CrtM) dehydrosqualene synthase (PDB ID: 2ZCS). These docking studies revealed that the synthesized derivatives showed high binding energies and strong H-bond interactions with the dehydrosqualene synthase validating the observed antimicrobial activity data. Based on antimicrobial activity and docking studies, the compounds 9c, 9d and 9e were identified as promising antimicrobial leads.

利用点击化学方法合成了一系列取代的三唑官能化的2 H-苯并[ b ] [1,4]恶嗪-3（4 H）-酮，并基于¹ H NMR，¹³ C NMR，IR和质谱进行了进一步表征学习。筛选所有合成的衍生物的体外抗菌活性。此外，完成了分子对接研究，以探索1,2,3-三唑-4-基-2 H-苯并[ b ] [1,4]恶嗪-3（4 H）-one与活性位点之间的结合相互作用中金黄色葡萄球菌（CrtM）脱氢角鲨烯合酶（PDB ID：2ZCS）。这些对接研究表明，合成的衍生物与脱氢角鲨烯合酶显示出高结合能和强H键相互作用，从而验证了所观察到的抗菌活性数据。基于抗菌活性和对接研究，化合物9c，9d和9e被确定为有前途的抗菌药物。
