During recent years, microwave irradiation has been extensively used for performing green organic synthesis. The aim of this study was to synthesize, through a microwave-assisted irradiation process, a natural surfactant with O/W emulsifying properties. Our attention was focused on polyglycerol esters of fatty acids that are biocompatible and biodegradable non-ionic surfactants widely used in f...

Background: Radiosensitization using nanoparticles is proposed as a novel strategy for treatment of different cancers. Superparamagnetic iron oxide nanoparticles (SPIONs) have been reported to enhance effects of radiotherapy in several researches. Objective: The objective of this research is to investigate the radiosensitization properties of polyglycerol coated SPIONs (PG-SPIONs) on U87-...

A polyglycerol dendrimer unimolecularly imprinted with D-(-)-fructose (Fru) was synthesized. The dendrimer formed adducts with several monosaccharides, Fru, D-(+)-galactose, D-(+)-glucose, D-(+)-mannose, and methyl-alpha-D-mannopyranoside (MMan), by removal of four water molecules. The dendrimer preferred Fru in the absence of N,N,N',N'-tetramethylmethylenediamine (TMDAM), whereas it preferred ...

Polyglycerol, porphyrin-cored dendrimers were synthesized by the click reaction of azide-cored polyglycerol dendrons and octaazidoporphyrin 19. The dendrons were synthesized divergently starting with TBDPS protected allyl alcohol 2. Two, three and four cycles of dihydroxylation-allyl etherification gave dendrons [G-2.5] 6, [G-3.5] 8, [G-4.5] 11, with four, eight, and sixteen alkene groups, resp...

ABSTRACT A magnetic nanoparticle supported hyperbranched polyglycerol catalyst was prepared readily from inexpensive starting materials in aqueous medium that catalyzed the synthesis of 4H-benzo[b]pyran under solvent-free conditions at room temperature. X-ray diffraction, transmission electron microscopy, thermal gravimetric analysis, vibrating sample magnetometry, and selected-area electron di...
