  Mechanism of Inactivation of β-Lactamases by Novel 6-Methylidene Penems Elucidated Using Electrospray Ionization Mass Spectrometry

  摘要：

  The reactions of 6-methylidene penems 4-7 with beta-lactamases (TEM-1, SHV-1, Amp-C) were characterized by electrospray ionization mass spectrometry (ESI-MS). The kinetics of the reactions were monitored, demonstrating that only one penem. molecule reacts to form an acyl-enzyme complex. For penem 5, the ESI-MS/MS spectrum of the hydrolysis product produced in the reaction was identical to the spectrum generated from a synthesized dihydro[1,4]thiazepine 10, confirming the rearrangement of the penem ring system to a seven-membered dihydro[1,4]thiazepine structure. Gas-phase ESI-MS/MS fragmentation data were rationalized due to tautomerization between imine and enamine substructures. ESI-MS/MS analysis of the T-6 trypsin-digested fragments of TEM-1 and SHV-1 demonstrated that the penems were only attached to Ser-70 of these class A beta-lactamases and that the penem ring structures were rearranged to seven-membered dihydro[1,4]thiazepines.

  This invention relates to certain tricyclic 6-alkylidene penems which act as a inhibitor of class-D enzymes. β-Lactamases hydrolyze β-lactam antibiotics, and as such serve as the primary cause of bacterial resistance. The compounds of the present invention when combined with β-lactam antibiotics will provide an effective treatment against life threatening bacterial infections. In accordance with the present invention there are provided compounds of formula I which are useful for treatment of bacterial infections having class-D enzymes associated therewith: wherein: One of A and B denotes hydrogen and the other an optionally substituted fused tricyclic heteroaryl group; and X is S or O.
