A series of novel N-[4-(substituted)-1,3-thiazol-2-yl]-2-(substituted)acetamide (9a–m) and methyl 2-(2-(2-(substituted)acetamido)thiazol-4-yl)acetate (9n–o) derivatives have been synthesized and compounds were characterised by spectral and analytical studies. All compounds were screened for their in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa
一系列新颖的N- [4-(取代的)-1,3-噻唑-2-基] -2-(取代的)乙酰胺(9a – m)和甲基2-(2-(2-(取代的)乙酰胺基)已经合成了噻唑-4-基)乙酸酯(9n - o)衍生物,并通过光谱和分析研究对化合物进行了表征。所有化合物进行了筛选针对其体外抗菌活性的金黄色葡萄球菌,大肠杆菌,铜绿假单胞菌和肺炎克雷伯氏菌纸片扩散法和针对抗真菌活性马尔尼菲青霉,须发癣菌,曲霉属 黄曲霉和曲霉 曲霉通过连续平板稀释法。化合物9b,9e,9m和9o对所有测试的细菌菌株均表现出生长抑制作用,MIC值在12.5至6.25μg/ ml之间变化。在测试的抗真菌活性化合物中,9a,9b,9d,9j,9k,9p和9n表现出对所有测试菌株的广泛活性。大多数新合成的化合物对真菌菌株而非细菌菌株均有效。但是,有些化合物如9a,9e,9j,9k和9i对某些细菌菌株表现出选择性敏感性,而它们无法维持其他菌株的生长。
