Amphiphilic peptide dendritic copolymer-doxorubicin nanoscale conjugate self-assembled to enzyme-responsive anti-cancer agent

Peptide dendrimer drug conjugate based nanoparticles are recently developed as a potential candidate for drug delivery vehicle. In this study, we prepared and characterized the enzyme-sensitive amphiphilc mPEGylated dendron-GFLG-DOX conjugate via two-step highly efficient click reaction. Dynamic lig... Full description

description: Peptide dendrimer drug conjugate based nanoparticles are recently developed as a potential candidate for drug delivery vehicle. In this study, we prepared and characterized the enzyme-sensitive amphiphilc mPEGylated dendron-GFLG-DOX conjugate via two-step highly efficient click reaction. Dynamic light scattering (DLS) and transmission electron microscope (TEM) studies demonstrated the mPEGylated dendron-GFLG-DOX conjugate self-assembled into compact nanoparticles with negatively charged surface. The nanoparticles with 9.62 wt% (weight percent) of DOX showed enzyme-sensitive property by drug release tests. The nanoparticles were shown to effectively kill cancer cells . The fluorescent image indicated that the nanoparticles could accumulate and retain within tumor for a long time. Moreover, the nanoparticles substantially enhanced antitumor efficacy compared to the free DOX, exhibiting much higher effects on inhibiting proliferation and inducing apoptosis of...
