Dendrimer-based nanoparticles for cancer therapy.

Folic acid-modified diatrizoic acid-linked dendrimer-entrapped gold nanoparticles as nanoprobes for targeted CT imaging of human cervical cancer

Peptide dendrimer-Doxorubicin conjugate-based nanoparticles as an enzyme-responsive drug delivery system for cancer therapy.

Peptide dendrimers have shown promise as an attractive platform for drug delivery. In this study, mPEGylated peptide dendrimer-doxorubicin (dendrimer-DOX) conjugate-based nanoparticle is prepared and characterized as an enzyme-responsive drug delivery vehicle. The drug DOX is conjugated to the periphery of dendrimer via an enzyme-responsive tetra-peptide linker Gly-Phe-Leu-Gly (GFLG). The dendr...

Effect of magnetic fluid hyperthermia with dendrimer coated iron oxide nanoparticles on breast cancer in BALB/c mice

Introduction: Magnetic fluid hyperthermia (MFH) is a promising therapeutic method in cancer therapy with using magnetic nanoparticles (NPs). In this study, we assessed the effect of MFH on mechanisms of cell death in murine breast cancer cell line (MC4-L2) and also the treatment of breast tumor in BALB/C mice using four generation dendrimer coated iron oxide nanoparticles (G4@I...

Comparison of the internalization of targeted dendrimers and dendrimer-entrapped gold nanoparticles into cancer cells.

Dendrimer-based nanotechnology significantly advances the area of targeted cancer imaging and therapy. Herein, we compared the difference of surface acetylated fluorescein isocyanate (FI) and folic acid (FA) modified generation 5 (G5) poly(amidoamine) dendrimers (G5.NHAc-FI-FA), and dendrimer-entrapped gold nanoparticles with similar modifications ([(Au(0))(51.2)-G5.NHAc-FI-FA]) in terms of the...

Targeted gadolinium-loaded dendrimer nanoparticles for tumor-specific magnetic resonance contrast enhancement

A target-specific MRI contrast agent for tumor cells expressing high affinity folate receptor was synthesized using generation five (G5) ofpolyamidoamine (PAMAM) dendrimer. Surface modified dendrimer was functionalized for targeting with folic acid (FA) and the remaining terminal primary amines of the dendrimer were conjugated with the bifunctional NCS-DOTA chelator that forms stable complexes ...
