Rerouting lipoprotein nanoparticles to selected alternate receptors for the targeted delivery of cancer diagnostic and therapeutic agents

Zheng G, Chen J, Li H & Glickson, JD Proceedings of the National Academy of Sciences, 2005 We report that a lipoprotein-based nanoplatform generated by conjugating tumor-homing molecules to the protein components of naturally occurring lipoproteins reroutes them from their normal lipoprotein receptors to other selected cancer-associated receptors.

High payload delivery of optical imaging and photodynamic therapy agents to tumors using phthalocyanine-reconstituted low-density lipoprotein nanoparticles

Li H, Marotta DE, Kim S, Busch TM, Wileyto EP & Zheng G Journal of Biomedical Optics, 2005 To improve the labeling efficiency of a low-density lipoprotein (LDL)-based photosensitizer (PS) for achieving high probe to protein payload, a tetra-tt-butyl silicon phthalocyanine bearing two oleate moieties at its axial positions, SiPcBOA,Continue Reading

Near-infrared optical imaging of B16 melanoma cells via low-density lipoprotein-mediated uptake and delivery of high emission dipole strength tris[(porphinato)zinc(II)] fluorophores

Wu SP, Lee I, Ghoroghchian PP, Frail PR, Zheng G, Glickson JD & Therien MJ Bioconjugate Chemistry, 2005 Meso-to-meso ethyne-bridged tris[(porphinato)zinc(II)] (PZn3) near-infrared (NIR) fluorophores (λemmax ∼800 nm) can be rendered sufficiently amphiphilic to enable their facile incorporation into the hydrophobic core of the apo form of low-density lipoprotein (apo-LDL).Continue Reading
