- Controllable Synthesis of Multiarm Star-Shaped Copolymers Composed of Phosphoester Chains and Their Application on Drug Delivery
Li Zhang, Dongjian Shi, Chunling Shi, Liangliang Dong, Xiaojie Li and Mingqing Chen
Version of Record online: 29 MAR 2017 | DOI: 10.1002/mabi.201600522
Amphiphilic multiarm star-shaped copolymers consisting of dendritic poly(amido amine) and biodegradable poly(phosphoester)s are controllably synthesized and co-assemble with doxorubicin into supramolecular micelles. Size and loading capacity of micelles can be tuned by simply altering the chain length of polymers. The biodegradability of polymer chains endows slow and sustained release of drugs. Therefore, these copolymers have great potential in drug delivery.
- Exploring Tyrosine-Triazolinedione (TAD) Reactions for the Selective Conjugation and Cross-Linking of N-Carboxyanhydride (NCA) Derived Synthetic Copolypeptides
Saltuk B. Hanay, Bas Ritzen, Dermot Brougham, Aylvin A. Dias and Andreas Heise
Version of Record online: 29 MAR 2017 | DOI: 10.1002/mabi.201700016
The tyrosine-triazolinedione reaction is used to selectively cross-link a copolymer of lysine and tyrosine. Reaction occurs only on the tyrosine offering the advantage of a selective click-like reaction on a natural amino acid in the synthetic polypeptides. This overcomes issues with functional non-natural amino acids commonly used for click reactions in polypeptides.
- Well-Defined Poly(Ortho Ester Amides) for Potential Drug Carriers: Probing the Effect of Extra- and Intracellular Drug Release on Chemotherapeutic Efficacy
Guoqing Yan, Jun Wang, Jiejie Qin, Liefeng Hu, Panpan Zhang, Xin Wang and Rupei Tang
Version of Record online: 29 MAR 2017 | DOI: 10.1002/mabi.201600503
To compare chemotherapeutic efficacy determined by tumoral extracellular and intracellular drug release strategies, poly(ortho ester amides)-based drug carriers with different pH-sensitivities are successfully constructed. In vitro and in vivo results demonstrate that the intracellular drug release strategy has the stronger overall therapeutic efficacy, which may provide a guidance to design an efficient drug carrier in chemotherapy.
- Physicochemical Characterization of the Shell Composition of PBCA-Based Polymeric Microbubbles
Lia Appold, Yang Shi, Stephan Rütten, Alexander Kühne, Andrij Pich, Fabian Kiessling and Twan Lammers
Version of Record online: 29 MAR 2017 | DOI: 10.1002/mabi.201700002
Polymeric microbubbles (MB) are useful for drug delivery purposes. The authors analyzed the influence of synthesis parameters on the molecular weight distribution of the polymer chains constituting the shell of poly(butyl cyanoacrylate) (PBCA) MB using gel permeation chromatography. More than 99% of the polymer chains composing the PBCA MB-shell were found to be below the kidney clearance threshold of 40 kDa.
- d-Fructose Modification Enhanced Internalization of Mixed Micelles in Breast Cancer Cells via GLUT5 Transporters
Xu Zhou, Xianyan Qin, Tao Gong, Zhi-Rong Zhang and Yao Fu
Version of Record online: 27 MAR 2017 | DOI: 10.1002/mabi.201600529
d-Fructose modified poly(ε-caprolactone)-polyethylene glycol (PCL-PEG-Fru) is self-assembled with D-α-tocopheryl polyethylene glycol 1000 succinate into mixed micelles (PPF MM), which shows enhanced internalization efficiency in MCF-7 cells with overexpressed GLUT5 transporters as compared to fructose-free mixed micelles (PPN MM). The results may contribute to the development of GLUT5-mediated cell specific targeting strategy.
