SummaryGlycopolymers with mannose units were readily prepared by click chemistry of an azido mannopyranoside derivative and a poly(propargyl acrylate-co-N-vinyl pyrrolidone). These glycopolymers were used as polymer surfactants, in order to obtain glycosylated polycaprolactone nanoparticles. Optimum stabilization for long time storage was achieved by using a mixture of glycopolymers and the non-ionic triblock copolymer Pluronic® F-68. The mannose moieties are accessible at the surface of nanoparticles and available for molecular recognition by concanavalin A lectin. Interaction of mannose units with the lectin were evaluated by measuring the changes in nanoparticles size by dynamic light scattering in dilute media.
8‐Amino‐3,6‐dioxaoctyl α‐D‐mannopyranoside and 8‐amino‐3,6‐dioxaoctyl β‐D‐galactopyranoside were prepared for coupling with a copolymer made from PCL macromonomers and MA. The new glycosyl compounds as well as PCL macromonomers were synthesized by appropriate techniques and fully characterized. The grafting of the latter with the functionalized copolymer was ascertained by 15N NMR experiments. The glycopolymers thus obtained were used in conjunction with Pluronic® F‐68 for the stabilization of PCL nanoparticles prepared by the emulsification‐diffusion technique. The stabilization of these nanoparticles upon storage and after centrifugation was investigated as well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
