Synthesis of 5-(7-hydroxyhept-3-enyl)-1,2-dithiolan-3-one 1-oxide, a core functionality of antibiotic leinamycin
摘要:
5-(7-Hydroxyhept-3-enyl)- 1,2-dithiolan-3-one 1-oxide 1 possessing both the 1,2-dithiolan-3-one 1-oxide five-membered ring and the double bond at the gamma position of the heterocycle, characteristic of the antibiotic leinamycin, was synthesized. In addition, the activated ester form of 1 was prepared that may be useful for coupling 1 to certain DNA-binding agents. (C) 2003 Elsevier Science Ltd. All rights reserved.

Glucose-responsive insulin conjugates that contain one or more trisaccharides are provided. Such insulin conjugates may display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose, even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule.
With the infection rate of Bordetella pertussis at a 60‐year high, there is an urgent need for new anti‐pertussisvaccines. The lipopolysaccharide (LPS) of B. pertussis is an attractive antigen for vaccine development. With the presence of multipleraresugars and unusual glycosyl linkages, the B. pertussis LPS is a highly challenging synthetic target. In this work, aided by molecular dynamics simulation

An insulin conjugate comprising or consisting of a tri-valent sugar cluster is described. In particular aspects, the insulin conjugate displays a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule such as Con A.

The invention relates to a synthetic oligosaccharide representing part of the repeating unit of the Clostridium difficile glycopolymer PS-I and having the sequence of the pentasaccharide a-L-Rhap- ( 1→3 ) -β-D-Glcp- ( 1→4 ) - [a-L-Rhap- ( 1→3 ] -a-D-Glcp- ( 1→2 ) -a-D-Glcp or a synthetic fragment or derivative thereof. Preferably, the claimed synthetic oligosaccharide bears at least one linker L for conjugation to a carrier protein or for immobilization on a surface. Further aspects of the invention relate to advantageous methods for synthesizing said synthetic oligosaccharide and oligosaccharide-protein conjugate as well as to uses thereof, in particular as vaccines and diagnostic tools.
Insulin conjugates comprising an insulin molecule covalently attached to at least one bi-dentate linker having two arms, each arm independently attached to a ligand comprising a saccharide and wherein the saccharide for at least one ligand of the linker is fucose are disclosed. The insulin conjugates display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule such as Con A.
