In this report, we used stepwise orthogonal click chemistry (SOCC) involving strain-promoted azide–alkyne cycloaddition (SPAAC) and microwave-assisted Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC) to assemble an anticancer drug (paclitaxel, PTX) and a targeting ligand (trivalent galactoside, TGal) on a fluorescent silicon oxide nanoparticle (NP) by using dialkyne linker 8 as a bridge. The fluorescent

A new linker system has been designed and applied to neoglycoprotein synthesis. Reaction of oligosaccharide omega-aminoalkyl glycosides with homobifunctional adipic acid p-nitrophenyl diesters in dry DMF gave the corresponding amide half ester in good yields and of sufficient stability to permit chromatographic purification. Subsequent conjugation with bovine serum albumin under very mild conditions

A multivalent galactosyl carborane derivative 10 (dendritic glyco-borane, DGB) was synthesized and demonstrated as a potential cell-targeting agent in BNCT with HepG2 cells. DGB 10 improved the delivery of boron to HepG2 cells and neutron irradiation data show DGB 10 with ten-fold improvement at killing the HepG2 cells over BSH.
Synthesis and biological evaluation of technetium-99m labeled galactose derivatives as potential asialoglycoprotein receptor probes in a hepatic fibrosis mouse model
Two galactose derivatives, a monovalent Tc-99m-MAMA-MGal galactoside and a divalent Tc-99m-MAMA-DGal galactoside, were synthesized and radiolabeled in high radiochemical purity (>98%). Dynamic microSPECT imaging and biodistribution study of two traces in normal and liver fibrosis mice showed that the Tc-99m-MAMA-DGal revealed higher specific binding to asialoglycoprotein receptors in liver and then rapidly excreted via both hepatobiliary system and renal clearance. The results suggest that Tc-99m-MAMA-DGal may be used as SPECT probes for noninvasive evaluation of asialoglycoprotein receptor-related liver dysfunction.

galactosyl ligands are individually immobilized on Cy3@MNPs, and the uptake efficiencies of the resulting galactosyl Cy3@MNPs by HepG2 and HeLa cells are investigated using confocal microscopy. The confocal images show that galactosyl Cy3@MNPs are sprayed over cytoplasm of the HepG2cells, indicating that the MNP uptake occurs via receptor‐mediated endocytosis that is followed by release from endosomes. The
