  Synthesis of carbosilane dendrimers having peripheral mannose and mannobiose

  摘要：

  The mannose monosaccharide derivative, acetylthiopropyl 2,3,4,6-tetra-O-acetyl-alpha-D-mannopyranoside (Man), and the mannobiose derivative, acetylthiopropyl 2,4,6-tri-O-acetyl-3-O-(2,3',4',6'-tetra-O-acetyl-alpha-D-mannopyranosyl)-alpha-D-mannopyranoside (alpha-1,3-Man), were synthesized respectively. These mannose derivatives were introduced into carbosilane dendrimer scaffolds of the zero and first generations. As a result, six carbosilane dendrimers were functionalized by Man and alpha-1,3-Man. Isothermal titration microcalorimetry was done to determine binding assay between mannose moieties of carbosilane dendrimer and concanavalin A. It was found that carbosilane dendrimers bound more efficiently to concanavalin A than free mannose (Me-alpha-Man) and mannobiose (Me-alpha-1,3-' Man). (c) 2005 Elsevier Ltd. All rights reserved.
