Biodegradable Hyperbranched Polyglycerol with Ester ...

    https://pubs.acs.org/doi/abs/10.1021/bm300966d
    Biodegradable hyperbranched polyglycerols (dHPGs) were synthesized through oxyanionic initiating hybrid polymerization of glycerol and glycidyl methacrylate. Due to the introduction of ester linkages into the hyperbranched polyglycerol backbone, dHPGs showed good biodegradability and low cytotoxicity. Benefiting from the existence of terminal hydroxyls and methacryloyl groups, both the ...Author: Mei Hu, Mingsheng Chen, Guolin Li, Yan Pang, Dali Wang, Jieli Wu, Feng Qiu, Xinyuan Zhu, Jian Sun

Water-Soluble Degradable Hyperbranched Polyesters: Novel ...

    https://pubs.acs.org/doi/10.1021/bm025738i
    A novel approach to hyperbranched polymers is presented in this work. Hyperbranched polyesters with a large amount of terminal hydroxyl groups are prepared by a one-pot synthesis from commercially available AB-type and CDn-type monomers (n ≥ 2). In this paper, Michael addition of diethanolamine (CD2) or N-methyl-d-glucamine (CD5) to methyl acrylate (AB) generates dominantly ADn-type ...Author: Chao Gao, Yimin Xu, Deyue Yan, Wei Chen

    Therefore, for the purposes of cell sorting, medical diagnosis and controlled drug delivery, the strategy for the synthesis of magnetic cobalt nanoparticles is based on the use of non-toxic, biosimilar and biodegradable hyperbranched polymers and dendrimers. Such compounds include hyperbranched polyester polyols (HBPO) of various generations.Author: O. I. Medvedeva, S. S. Kambulova, O. V. Bondar, A. R. Gataulina, N. A. Ulakhovich, A. V. Gerasimov, ...

    These core-shell biodegradable hyperbranched polyesters have been used as drug delivery systems (DDS) so as to enhance the solubility of highly hydrophobic molecules. Pyrene has been studied as a model to evaluate the potential drug transport capability and the critical micelle concentration (CMC) of these amphiphilic systems.Author: Stefano Stefani, Sunil K.

    Jan 31, 2020 · Rod-like mesoporous silica nanoparticles with pH-responsive amphiphilic hyperbranched polyester shells were prepared for doxorubicin (DOX) delivery. First, rod-shaped mesoporous silica nanoparticles (MSNs) were obtained, then hydrophobic hyperbranched polyester Boltorn H40 (H40) was grafted on their surface. The H40 coated MSNs were next treated with amine-functionalized …Author: Reza Bafkary, Shirin Ahmadi, Faeze Fayazi, Mehdi Karimi, Yousef Fatahi, Seyed Mostafa Ebrahimi, Fate...
