Abstract Chemical modification of penicillin β-lactam ring was made. Six thiazolidine amides were produced through N4-C7 β-lactam ring opening of penicillin V methyl ester with various aliphatic, aromatic, and heterocyclic primary amines. Five 8-hydroxypenillic acid derivatives with side chains of methyl, propyl, benzyl, and diethylaminoethyl groups were yielded via β-lactam ring rearrangement from 6-aminopenicillanic
摘要对青霉素β-内酰胺环进行了化学修饰。通过青霉素V甲酯的N4-C7β-内酰胺开环,与各种脂肪族,芳香族和杂环伯胺生成六种噻唑烷酰胺。通过β-内酰胺环重排,由6-氨基青霉酸(6-APA)得到五个具有甲基,丙基,苄基和二乙基氨基乙基侧链的8-羟基青霉酸衍生物。采用平行合成方法对8-羟基青霉烯酸进行烷基化,使青霉素V甲酯的β-内酰胺开环。评价了化合物的生物活性。
