chemistry made possible the prediction of the three-dimensional structures of γ-lactam analogues of penems and carbapenems before the analogues were made. Molecular superpositioning showed that these novel structures with a 7β-acylamino side-chain present the pharmacophoric groups in close spatial similarity to the groups in biologically active cephalosporin and penicillin antibiotics. This suggests
计算化学使得在制造类似物之前预测 Penems 和 Carpenems 的 γ-内酰胺类似物的三维结构成为可能。分子叠加显示,这些具有 7β-酰基氨基侧链的新结构与具有生物活性的头孢菌素和青霉素抗生素中的药效基团在空间上非常相似。这表明 8-氧代-7-酰氨基-1-氮杂双环[3.3.0]-辛-2-烯-2-羧酸盐和 4-硫代类似物可以位于识别头孢菌素和青霉素的必需细菌青霉素结合蛋白的相同活性位点。报道了这些化合物的合成。γ-内酰胺类药物表现出低但可检测的抗菌活性水平,并表明其他 γ-内酰胺类药物有望实现实质性活性。
