A class of 7-oxo-2,6-diazabicyclo-[3.2.0]-heptane-6-sulfonic acid compounds substituted at the two position of the bicyclic ring with a heterocyclylaminocarbonyl group or a carbocyclylaminocarbonyl group are β-lactamase inhibitors. The compounds and their prodrugs and pharmaceutically acceptable salts are useful in the treatment of bacterial infections in combination with β-lactam antibiotics. In particular, the compounds are suitable for use with β-lactam antibiotics (e.g., imipenem and ceftazidime) against micro-organisms resistant to β-lactam antibiotics due to the presence of the β-lactamases.

Bridged monobactam beta-lactamase inhibitors were prepared and evaluated as potential partners for combination with imipenem to overcome class C beta-lactamase mediated resistance. The (S)-azepine analog 2 was found to be effective in both in vitro and in vivo assays and was selected for preclinical development.

[EN] A class of 7-oxo-2,6-diazabicyclo-[3.2.0]-heptane-6-sulfonic acid compounds substituted at the two position of the bicyclic ring with a heterocyclylaminocarbonyl group or a carbocyclylaminocarbonyl group are ß-lactamase inhibitors. The compounds and their prodrugs and pharmaceutically acceptable salts are useful in the treatment of bacterial infections in combination with ß-lactam antibiotics. In particular, the compounds are suitable for use with ß-lactam antibiotics (e.g., imipenem and ceftazidime) against micro-organisms resistant to ß-lactam antibiotics due to the presence of the ß-lactamases. [FR] L'invention concerne une classe de composés d'acide 7-oxo-2,6-diazabicyclo-[3.2.0]-heptane-6-sulfonique, substitués à la position 2 du noyau bicyclique par un groupe hétérocyclylaminocarbonyle ou un groupe carbocyclylaminocarbonyle, qui sont des inhibiteurs de bêta-lactamase. Ces composés, ainsi que leurs promédicaments et leurs sels pharmaceutiquement acceptables, sont utiles dans le traitement d'infections bactériennes lorsqu'ils sont associés à des antibiotiques bêta-lactame (p. ex. imipenem and ceftazidime) pour lutter contre des micro-organismes résistants aux antibiotiques bêta-lactame, du fait de la présence des bêta-lactamases.
