In an attempt to find a new class of antimicrobial agents, a series of thiazole, thiophene, pyrazole and other related products containing benzothiazole moiety were prepared via the reaction of N-(benzothiazol-2-yl)-2-cyanoacetamide (1) with appropriate chemical reagents. These compounds were screened for their antibacterial activity against Gram-positive bacteria (Staphylococcus aureus and Streptococcus
为了寻找一类新的抗菌剂,通过N-(苯并噻唑-2-基)-2-氰基乙酰胺(1)的反应制备了一系列噻唑,噻吩,吡唑和其他含有苯并噻唑部分的相关产品。适当的化学试剂。筛选了这些化合物对革兰氏阳性菌(金黄色葡萄球菌和化脓性链球菌),革兰氏阴性菌(Pseudomonas phaseolicola和Pseudomonas fluorescens)的抗菌活性以及对尖孢镰刀菌和烟曲霉的抗真菌活性。。在合成的化合物中,噻吩13与氯霉素对金黄色葡萄球菌的活性相同(MIC 3.125μg/ mL),但其活性比对氯霉素对化脓性链球菌的活性低50%。发现噻唑3和吡唑并[1,5- a ]嘧啶21b表现出最有效的体外抑菌活性,MIC(6.25μg/ mL)对烟曲霉和尖孢镰刀菌具有抑制作用。通过元素分析和光谱数据确定了新合成化合物的结构。
