were found to be the same as cefadroxil monohydrate. Compounds 1 and 10 were more effective than cefadroxil monohydrate against S. faecalis with 25 and 37.5 micrograms/ml MBC values, respectively. None of the compounds and cefadroxil monohydrate proved to be effective against P. aeruginosa (MBC: greater than 100 micrograms/ml). While cefadroxil monohydrate had no activity against yeast-like fungi, compounds
十一个新的7- [2-(2-二氢-5-取代-6-thioxo-2H-1,3,5-噻二嗪-3(4H)-基)-2-(4-羟基苯基)乙酰氨基] -3-甲基-通过头孢氨苄一水合物,甲醛和取代的二硫代氨基甲酸钾的反应合成了3-cephem-4-羧酸衍生物。光谱数据和元素分析已阐明了它们的结构。在体外测试了标题化合物对革兰氏阳性菌(金黄色葡萄球菌,粪链球菌),革兰氏阴性菌(大肠杆菌,铜绿假单胞菌)和酵母样真菌(白色念珠菌,副盘状梭菌,恒星菌)的抗菌活性。 ,C. pseudotropicalis)与头孢曲氨酯一水合物相比。化合物1和10对金黄色葡萄球菌(MBC:37.5微克/毫升)和化合物1对大肠杆菌(MBC:发现75微克/毫升与头孢氨苄一水合物相同。化合物1和10相对于头孢曲霉一水合物对粪链球菌更有效,分别具有25和37.5微克/毫升的MBC值。没有一种化合物和头孢羟氨苄一水合物被证明对铜绿假单胞菌
