the antibacterial activity of some new macromolecules such as bis‐pyrazoline, bis‐pyrazole, bis‐pyrimidines prepared from the reaction of bis‐chalcone with thiosemicarbazide/phenyl hydrazine/guanidine hydrochloride/thiourea. All the macromolecules have been characterized by IR, 1H NMR, 13C NMR, mass and elemental analyses. The antibacterial activity of these compounds was first tested in vitro by the
我们研究了一些新的大分子的抗菌活性,例如双吡唑啉,双吡唑,双嘧啶,它们是由双查尔酮与硫代氨基脲/苯基肼/盐酸胍/硫脲反应制得的。所有大分子均已通过IR,1 H NMR,13 C NMR,质量和元素分析进行了表征。这些化合物的抗菌活性首先通过椎间盘扩散测定法在体外对两种革兰氏阳性细菌和两种革兰氏阴性细菌进行了测试,然后参照标准药物氯霉素确定了最低抑菌浓度。结果表明吡唑啉衍生物对鼠伤寒沙门氏菌和大肠杆菌具有较好的抗菌活性。 比参考药物氯霉素。
