Sulfazecin (1) is a monocyclic β-lactam antibiotic isolated from strain G-6302, Pseudomonas acidophila. As a key intermediate for the synthesis of sulfazecin derivatives, 3-amino-2-azetidinone (16) was synthesized from penicillins, and various new compounds were synthesized by acylation and sulfonation of 16. Some of these new compounds showed potent antibacterial activity.
磺胺嘧啶(1)是从嗜酸性假单胞菌 G-6302 菌株中分离出来的一种单环 β-内酰胺类抗生素。作为合成磺胺嘧啶衍生物的关键中间体,3-氨基-2-氮杂环丁酮(16)是由青霉素类化合物合成的。其中一些新化合物具有很强的抗菌活性。
