Dual-Drug Conjugated Glyco-Nanoassemblies for Tumor-Triggered Targeting and Synergistic Cancer Therapy.

Drug-conjugated nanoassemblies potentiate the efficiency of anticancer drugs through the advantages of high drug-loading capacity and passive/active targeting ability in cancer therapy. This study describes the synthesis of gemcitabine (Gem) and cisplatin (cisPt) dual-drug-functionalized glyco-nanoassemblies (GNs) for anticancer drug delivery systems. It also investigates the pH-triggered drug delivery of the conventional anticancer drug cisPt.

Increasing the biocompatibility of graphene-based hybrid nanostructures with glycopolymer.

Hybrid nanostructures decorated with glycopolymers are appropriate for biomedical applications. In this paper, the results are obtained from nanographene (NG) decorated with glycoblock copolymer to increase their potential in use in therapies and in examining lectin interactions. A pyren-1-ylmethyl 4-cyano-4-((phenylcarbonothioyl)thio)pentanoate (CPADB-py) chain transfer agent was used in the synthesis of methyl methacrylate glycoblock copolymers (P2 and P3) by reversible addition-fragmentation chain transfer (RAFT) polymerization to adhere the polymer to the nanographene surface.

Phthalocyanine-Conjugated Glyconanoparticles for Chemo-photodynamic Combination Therapy.

Combination cancer therapy based on multifunctional nanomaterials has attracted great attention. The present work focuses on the preparation of the glycopolymeric nanoparticle, which contains a photosensitizer (zinc(II)phthalocyanine, ZnPc) and an anticancer drug (Doxorubicin, Dox). First, a novel mono azide-functional ZnPc-N with seven hydrophilic ethylene oxide chains was synthesized.

Glycopolymer decorated multiwalled carbon nanotubes for dual targeted breast cancer therapy.

Carbon-based nanomaterials (CNMs) have attracted great attention in biomedical applications such as cancer imaging and therapy. CNMs, which are currently used in a wide range of applications, suffer from drawbacks of toxicity and low biocompatibility. Either noncovalent or covalent functionalization of CNMs with hydrophilic and biocompatible polymers which help to block hydrophobic interactivity between CNMs and cells can greatly increase their biocompatibility by eliminating their probable toxicity towards living organisms.

Glyconanoparticles for Targeted Tumor Therapy of Platinum Anticancer Drug.

An important requirement to decrease the side effects of chemotherapy drugs is to develop nanocarriers with precise biological functions. In this work, a set of glyconanoparticles was prepared via self-assembly of amphiphilic glycoblock copolymers for the targeted delivery of a hydrophobic chemotherapy drug. Well-defined glycoblock copolymers that consist of 1,1-di--butyl 3-(2-(metyloyloxy)ethyl)-butane-1,1,3-tricarboxylate (MAETC) together with three different protected-sugar moieties (β-d-glucopyranoside, β-d-mannopyranoside, and β-l-fucopyranoside) were synthesized by using reversible addition-fragmentation chain-transfer polymerization.
