Poly(propylene imine) dendrimer-grafted nanocrystalline cellulose: Doxorubicin loading and release behavior

Polypropylene imine dendrimer mediated solubility enhancement: effect of pH and functional groups of hydrophobes.

Dendrimers today are known for their three dimensional, monodispersed, highly branched, macromolecular nano-scopic architecture with number of reactive end groups. Dendrimers have been reported to act as solubilizing agents to host both hydrophilic and hydrophobic drugs. The present study was performed to investigate the effect of pH on poly(propylene) imine dendrimers (5.0G) mediated solubilit...

Comparison of generation 3 polyamidoamine dendrimer and generation 4 polypropylenimine dendrimer on drug loading, complex structure, release behavior, and cytotoxicity

BACKGROUND Polyamidoamine (PAMAM) and polypropylenimine (PPI) dendrimers are the commercially available and most widely used dendrimers in pharmaceutical sciences and biomedical engineering. In the present study, the loading and release behaviors of generation 3 PAMAM and generation 4 PPI dendrimers with the same amount of surface amine groups (32 per dendrimer) were compared using phenylbutazo...

antimicrobial activities of the polypropylene imine dendrimer aginst bacteria isolated from rural water resources

conclusions the ppi-g2 dendrimer with end amine groups exhibited a positive impact on the removal of dominant bacterial isolated strains. therefore, it is possible to use these nanodendrimers as a safe and effective material for water disinfection in the future. results the most important isolated bacteria were escherichia coli 37 (48.7%), klebsiella oxytoca 12 (15.8%), proteus mirabilis 3 (4%)...

Poly(propylene imine) dendrimer caps on mesoporous silica nanoparticles for redox-responsive release: smaller is better.

To elucidate the importance of the size of capping agents in stimulus-induced release systems from mesoporous silica nanoparticles (MSNs), the effectiveness of poly(propylene imine) dendrimers in controlling the model drug release was studied. MCM-41-type MSNs were synthesized and characterized. Fluorescent compounds (fluorescein disodium salt and carboxyfluorescein) were loaded in the porous s...
