Abstract

Computational 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 that 8-oxo-7- ...
