dithiocarbamic acid salts. The structures were evident from chemical and spectral analysis. The antimicrobial activities of the compounds were investigated against some gram‐positive (Staphylococcus aureus and Streptococcus faecalis) and gram‐negative (Escherichia coli and Pseudomonas aeruginosa) bacteria and some yeast‐like fungi (Candida albicans, C. parapsilosis, C. stellatoidea and C. pseudotropicalis)
通过氨苄青霉素三水合物、甲醛和二硫代氨基甲酸盐的反应合成了具有α-[二氢-5-取代的6-硫代-2H-1,3,5-噻二嗪-3(4H)-基]苄青霉素结构的化合物。从化学和光谱分析中可以明显看出结构。研究了这些化合物对一些革兰氏阳性菌(金黄色葡萄球菌和粪链球菌)和革兰氏阴性菌(大肠杆菌和铜绿假单胞菌)和一些酵母样真菌(白色念珠菌、近平滑念珠菌、星状念珠菌和星状芽孢杆菌)的抗菌活性C.pseudotropicalis) 和霉菌如红色毛癣菌、须癣毛癣菌、犬小孢子菌、石膏分枝杆菌、青霉菌和曲霉属通过管稀释法。除了 MIC(最小抑制浓度),MBC(最低杀菌浓度)和 MFC(最低杀菌浓度)值以氨苄青霉素三水合物为标准测定。通常发现合成的化合物对金黄色葡萄球菌和粪链球菌的作用与氨苄西林三水合物一样有效,而对大肠杆菌的作用不如氨苄西林三水合物。合成的化合物和氨苄青霉素三水合物在所研究的浓度下均对铜绿假单胞菌无
