  AmpC beta-lactamase confers resistance to beta-lactam antibiotics in many Gram negative bacteria. Inducible expression of AmpC requires an N-acetylglucosaminidase termed NagZ. Here we describe the synthesis and characterization of hydroxyazepane inhibitors of NagZ. We find that these inhibitors enhance the susceptibility of clinically relevant Pseudomonas aeruginosa to beta-lactams.

  AmpCβ-内酰胺酶赋予许多革兰氏阴性细菌对β-内酰胺抗生素的抗性。AmpC的诱导表达需要一个称为NagZ的N-乙酰氨基葡糖苷酶。在这里，我们描述了NagZ的羟基氮杂环庚烷抑制剂的合成和表征。我们发现这些抑制剂增强了临床相关的铜绿假单胞菌对β-内酰胺的敏感性。

  Escherichia coli NagZ. Capitalizing on the flexibility of azepanes and the active site tolerances of hexosaminidases, we explore the effects of epimerization of stereocenters at C-3, C-5 and C-6 and C-alkylation at the C-2 or C-7 positions. Accordingly, epimerization at C-6 (L-ido) and at C-5 (D-galacto) led to selective HexAB inhibitors whereas introduction of a propyl group at C-7 on the C-3 epimer furnished

  A series of seven-membered iminosugars bearing an acetamido group beta- or gamma- to the endocyclic nitrogen have been synthesized via simple transformations of previously described polysubstituted azepanes. These tetra- and trihydroxylated acetamido azepanes are ring homologues of 2-acetamido-1,2-dideoxy-glyconojirimycins and 2-acetamido-1-N-iminosugars respectively. Screening of these azepanes towards a range of commercially available glycosidases demonstrated their potential as selective and potent hexosaminidase inhibitors with K-i's in the submicromolar range. A correlation between the relative configuration of the azepanes and their ability to inactivate hexosaminidases was also observed for the first time for this class of compounds with one notable exception for the most potent compound.

  Here we report the synthesis of a series of polyhydroxylated 3- and 5-acetamido azepanes and detail the molecular basis of their inhibition of family 84 glycoside hydrolases. These family 84 enzymes include human O-GlcNAcase, an enzyme involved in post-translational processing of intracellular proteins modified by O-linked beta-N-acetylglucosamine residues. Detailed structural analysis of the binding of these azepanes to BtGH84, a bacterial homologue of O-GlcNAcase, highlights their conformational flexibility. Molecular mechanics and molecular dynamics calculations reveal that binding to the enzyme involves significant conformational distortion of these inhibitors from their preferred solution conformations. The binding of these azepanes provides structural insight into substrate distortion that likely occurs along the reaction coordinate followed by O-GlcNAcase during glycoside hydrolysis. This class of inhibitors may prove to be useful probes for evaluating the conformational itineraries of glycosidases and aid the development of more potent and specific glycosidase inhibitors.

The study of two distinct D-gluco and L-ido stereochemistries for the tetrol pattern as well as R and S configurations for the C-2 carbon bearing the C-alkyl chain is reported. We observed that C-alkylation of the L-ido tetrahydroxylated azepane converts it from an α-L-fucosidase to a β-glucosidase and β-galactosidase inhibitor while N-alkylation of the
