In an effort to find a new pharmacologically dynamic molecule, we report here the synthesis and in vitro antimicrobial activity of various N-(4-methyl-5-(4-((substituted phenylamino) methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)thiazol-2-yl) benzamides. The structures of newly synthesized compounds were assigned on the bases of IR, 1H NMR, 13C NMR, and mass spectral data. Synthesized compounds were screened for their antibacterial and antifungal activities on gram-positive bacteria (Staphylococcus aureus and Streptococcus pyogenes), gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) and three fungi (Candida albicans, Aspergillus niger and Aspergillus clavatus) by serial broth dilution method. Compounds 5e and 5k were associated with considerable potential antibacterial and compounds 5a and 5b antifungal activities.
我们在此报道了一系列N-(4-甲基-5-(4-((取代苯胺基)甲基)-5-硫酮-4,5-二氢-1,3,4-噁二唑-2-基)噻唑-2-基)苯甲酰胺类化合物的合成及其体外抗微生物活性,以寻找一种新的药理学活性分子。新合成化合物的结构基于IR、1H NMR、13C NMR及质谱数据进行指认。合成的化合物通过连续肉汤稀释法筛选其对革兰氏阳性细菌(金黄色葡萄球菌和酿脓链球菌)、革兰氏阴性细菌(大肠杆菌和铜绿假单胞菌)及三种真菌(白色念珠菌、黑曲霉和棒曲霉)的抗菌和抗真菌活性。化合物5e和5k显示出显著的潜在抗菌活性,而化合物5a和5b则表现出抗真菌活性。
