Biotin-guided anticancer drug delivery with acidity-triggered drug release

27-May-2015 | Soyeon Park; Eunjin Kim; Won Young Kim; Chulhun Kang; Jong Seung Kim, Chemical Communication, 2015

A novel biotin-guided anticancer drug delivery system, prodrug 9, consisting of biotin, nitrobenzene, and doxorubicin, with acid-triggered drug releasing capability was synthesized. Its cellular uptake and anticancer activity are selective to the HepG2 cell line over the WI-38 cell line, as ...

Functionalized PEG‐b‐PAGE‐b‐PLGA triblock terpolymers as materials for nanoparticle preparation

22-May-2015 | Justyna A. Czaplewska, Tobias C. Majdanski, Markus J. Barthel, Michael Gottschaldt, Ulrich S. Schubert, Journal of Polymer Science Part A: Polymer Chemistry, 2015

ABSTRACT A series of poly(ethylene glycol)‐block‐poly(allyl glycidyl ether) (PEG‐b‐PAGE) macroinitiators are prepared using the living anionic ring‐opening polymerization (AROP) technique, and applied for further copolymerization studies. To overcome the low reactivity of the secondary ...

PEGylated Liposomes as Carriers of Hydrophobic Porphyrins

22-May-2015 | Monika Dzieciuch; Sami Rissanen; Natalia Szydłowska; Alex Bunker; Marta Kumorek; Dorota Jamróz; Ilpo Vattulainen; Ma ..., Journal of Physical Chemistry B, 2015

Sterically stabilized liposomes (SSLs) (PEGylated liposomes) are applied as effective drug delivery vehicles. Understanding the interactions between hydrophobic compounds and PEGylated membranes is therefore important to determine the effectiveness of PEGylated liposomes for delivery of drugs or ...

Lectin-Gated, Mesoporous, Photofunctionalized Glyconanoparticles for Glutathione-Responsive Drug Delivery

21-May-2015 | Juan Zhou; Nanjing Hao; Thareendra DeZoysa; Mingdi Yan; Olof Ramstrom, Chemical Communication, 2015

A stimuli-responsive drug delivery system based on fluorescent, lectin-gated, mesoporous glyconanoparticles has been developed and evaluated in normal- and cancer lung epithelial cells. The gating process proved efficient, exhibiting good sealing properties in the absence of the glutathione redox ...
