Combinational chemotherapy is often used to prevent drug induced resistance in cancer. The aim of this work is to test whether the co-delivery of drugs within one nanoparticle can result in increased synergistic effects of both drugs. Therefore, a micelle system with two different compartments, one for the drug curcumin and one for the conjugation of… (More)
Polymeric versions of deacetylated auranofin, a gold complex with a sugar ligand, were prepared by post-modifying RAFT glycopolymers. Micellisation of a block copolymer containing pendant Au(I) units produced nanoparticles with an increased anti-proliferative effect against OVCAR-3 human ovarian carcinoma cells.
Boronic esters are investigated as a pathway to conjugate biological molecules to polymers. Although the stability of the boronic ester was slightly dependent on the molecular weight of the polymer and the pH value, the conjugates were stable when micelles were endocytosed by cells. Only the onset of apoptosis led to cleavage of the boronic ester.
UNLABELLED Macromolecular ruthenium (Ru) complexes are a promising avenue to better, and more selective, chemotherapeutics to treat metastatic cancers. In our previous research, amphiphilic block copolymeric micelles carrying RAPTA-C (RuCl2(p-cymene)(PTA)) were demonstrated to improve the cellular uptake and cytotoxicity of RAPTA-C (Blunden et al., 2013).… (More)
A new micelle delivery platform based on albumin coated nanoparticles is able to selectively deliver the payload to cancerous cells while healthy cells remain less affected. The technology is simple and can be used in a one-pot procedure.
In this study, a novel technique was used for the reversible attachment of folic acid on the surface of polymeric micelles for a tumor-specific drug delivery system. The reversible conjugation is based on the interaction between phenylboronic acid (PBA) and dopamine to form a borate ester. The conjugation is fast and efficient and in vitro experiments via… (More)
The delivery of macromolecular platinum drugs into cancerous cells is enhanced by conjugating the polymer to albumin. The monomers N-(2-hydroxypropyl)methacrylamide (HPMA) and Boc protected 1,3-diaminopropan-2-yl acrylate (Ac-DAP-Boc) are copolymerized in the presence of a furan protected maleimide functionalized reversible addition-fragmentation chain… (More)
The biodistribution of micelles with and without folic acid targeting ligands were studied using a block copolymer consisting of acrylic acid (AA) and polyethylene glycol methyl ether acrylate (PEGMEA) blocks. The polymers were prepared using RAFT polymerization in the presence of a folic acid functionalized RAFT agent. Oxoplatin was conjugated onto the… (More)
