The structures of nocardicins A and B, novel monocyclic beta-lactam antibiotics produced by a strain of Nocardia, have been established as 1 and 2, respectively, on the basis of spectroscopic and chemical evidence. They are the first examples of monocyclic beta-lactam antibiotics possessing relatively high antimicrobial activity, and are stereochemically and biologically related to penicillins and
根据光谱和化学证据,诺卡氏菌菌株生产的新型单环β-内酰胺抗生素诺卡氏菌素A和B的结构分别确定为1和2。它们是具有相对较高抗菌活性的单环β-内酰胺抗生素的首例,并且在化学和生物学上与青霉素和头孢菌素有关。
