Antibacterial activity is exhibited by β-lactams having the formula
wherein R is hydrogen or methoxy;
R1 is acyl;
R2 is alkyl, arylalkyl, carboxyalkyl, alkoxycarbonylalkyl, NH2-(CH2)n-, HO-(CH2)n- or aryl, wherein n is 2, 3 or 4; and
M8 is hydrogen or a cation;
with the proviso that if M⊕ is hydrogen the R1 or R2 group contains a basic function.
β-内酰胺具有抗菌活性,其式为
其中 R 为氢或甲氧基;
R1 是酰基
R2 是烷基、芳烷基、羧基、烷氧基羰基烷基、NH2-(CH2)n-、HO-(CH2)n- 或芳基,其中 n 是 2、3 或 4;以及
M8 是氢或阳离子;
但如果 M⊕ 是氢,则 R1 或 R2 基团含有碱基官能团。
