Abstract: The relationship between conformation and activity of three typical double-ring β-lactam antibioties:penicillin,△3-cephalosprins and △2-cephalosprins was studied in this paper. It is found that the configuration of the bridge carbon atom and the atom attached to the side amide is an important structural factor for their activities.
