A series of imidazothiazole derivatives were synthesized via Claisen–Schmidt condensation of aldehyde 3, and different methyl ketones and their chemical structures were confirmed using 13C NMR, 1H NMR and LC–MS. In addition, the molecular structure of compound 3 was defined by single-crystal X-ray diffraction. The antibacterial and antifungal activities of synthesized compounds were investigated by
通过Claisen-Schmidt醛3的缩合反应合成了一系列咪唑并噻唑衍生物,并通过13 C NMR,1 H NMR和LC-MS证实了不同的甲基酮及其化学结构。另外,化合物3的分子结构通过单晶X射线衍射确定。通过扩散法研究了合成化合物对三种病原菌(铜绿假单胞菌,大肠埃希菌和金黄色葡萄球菌)和一种病原真菌(尖孢镰刀菌)的抗菌和抗真菌活性。化合物3显示出显着的抗细菌活性大肠杆菌和铜绿假单胞菌(MIC≤0.2 mg / ml)。关于抗真菌活性,所有的分子显示出非常有趣的结果与尖孢镰孢(IC 50 ≤0.07毫克/毫升)。这些结果被分子对接研究所证实,例如某些化合物显示出对受体活性位点的最佳结合能和亲和力。
