derivatives. The structures of the synthesized compounds were established by extensive spectroscopic studies (FTIR, 1H NMR, 13C NMR, 2D NMR, LC-MS) and elemental analysis. The structure of (E)-6-methoxy-3-(1-(2-(4-p-tolylthiazol-2-yl)hydrazono)ethyl)-2H-chromen-2-one (7d) was unambiguously confirmed by X-ray crystallography analysis. Hybrid molecules were evaluated for their potential as anti-tubercular
一系列总21噻唑香豆素衍生物的图7a-U ,连接经由肼键是通过环化汉奇合成。在21个导数中,有14个导数。7b-d,7g,7i-k,7n和7p-u是新的衍生物。通过广泛的光谱研究(FTIR,1 H NMR,13 C NMR,2D NMR,LC-MS)和元素分析,确定了合成化合物的结构。的结构(ë)-6-甲氧基-3-(1-(2-(4-P-tolylthiazol -2-基)亚肼基)乙基)-2- ħ -色烯-2-酮(7d的X射线晶体学分析清楚地证实了)。评估了杂合分子作为抗结核分枝杆菌H37Rv ATCC 25618的抗结核药以及抗大肠杆菌,产气肠杆菌,伤寒沙门氏菌,肺炎链球菌和金黄色葡萄球菌的抗菌剂的潜力。所有化合物均显示出对所有病原体的显着效力,MIC值为31.25至250μg/ mL,其中化合物7i,7j,7k,7q和7t与标准药物链霉素,卡那霉素,万古霉素和异烟肼相比,具有更好的抑制活
