  Characterization of a transglycosylase domain of Streptococcus pneumoniae PBP1b

  摘要：

  Inhibitors of transglycosylases may serve as potent antibiotics that are less prone to resistance development in bacterial pathogens. To facilitate the search of such compounds, a transglycosylase (TGase) domain of the membrane integral multidomain Streptococcus pneumoniae PBP1b was cloned and expressed. This TGase domain was characterized by a substrate-dependent fluorescence coupled enzyme assay and an inhibitor-tethered surface plasmon resonance binding assay. Both assays show that the catalytic efficiency of the domain is comparable to that of the monofunctional transglycosylases, and it is fully active in the absence of other domains. The isolation of the active TGase domain makes it possible to screen for potential antibiotics targeting transglycosylases. (c) 2006 Elsevier Ltd. All rights reserved.

Whereas, the thioglycosides could be easily coupled to simple alcohols in excellent yields using the glycosylation promoting system N-iodosuccinimide and TMS triflate, these conditions could not effectuate coupling to the C4-hydroxy group possessing flanking

  This work describes a large‐scale synthesis of per‐O‐acetylated mono‐ and disaccharides using a stoichiometric amount of acetic anhydride in the presence of LiClO4 under solvent‐free conditions. The peracetylated saccharides underwent subsequent anomeric bromination and thioglycosidation in one‐pot to yield synthetically valuable building blocks.

  A series of N-acyl, N-alkoxycarbonyl, and N-alkylcarbamoyl derivatives of 2′-deoxy-glucosyl bearing oleanolic saponins were synthesized and evaluated against HL-60, PC-3, and HT29 tumor cancer cells. The SAR studies revealed that the activity increased in order of conjugation of 2′ -amino group with carbamate > amide > urea derivatives.
