are as defined in the specification and to pharmaceutically acceptable acid addition salts, optically pure enantiomers, racemates or diastereomeric mixtures thereof. The compounds are γ-secretase inhibitors which can be useful in the treatment of Alzheimer's disease or common cancers including, but not limited to, cervical carcinomas and breast carcinomas and malignancies of the hematopoietic system.

chemistry made possible the prediction of the three-dimensional structures of γ-lactamanalogues 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
