γ-Lactams with structures analogous to both penicillin (1) and cephalosporin (2) antibiotics have been synthesised. These compounds show high reactivity towards modest nucleophiles in keeping with their design as potential inhibitors of bacterial cell wall biosynthesis. Reactive γ-lactam analogues 27 and 29 of β-lactamase inhibitors such as 22 have also been prepared. An X-ray crystal structure of the cephalosporin analogue 8 has allowed structural comparisons to be made with the classical β-lactam antibiotic cephaloridine (30).
已合成具有类似于青霉素(1)和头孢菌素(2)抗生素结构的γ-内酯。这些化合物对适度亲核试剂表现出高度反应性,符合其作为细菌细胞壁生物合成潜在抑制剂的设计。还制备了类似于β-内酰胺酶抑制剂22的反应性γ-内酯类似物27和29。头孢菌素类似物8的X射线晶体结构使得可以与经典的β-内酰胺抗生素头孢利定(30)进行结构比较。
