چکیده
Novel GSH- and pH-responsive supramolecular vesicles constructed by an amphiphilic inclusion complex formed from water-soluble pillar[5]arene and lysine derivative have been successfully developed, which can efficiently encapsulate anticancer drug MTZ and show rapid MTZ-release in a simulated acidic tumor environment with high GSH concentration, and exhibit potent antitumor activity.

pH-Responsive supramolecular vesicles assembled by water-soluble pillar[5]arene and a BODIPY photosensitizer for chemo-photodynamic dual therapy.
Supramolecular vesicles which can successfully encapsulate DOX and exhibit rapid drug release in a low-pH environment are constructed based on the host-guest interaction of water-soluble pillar[5]arene and a BODIPY derivative. They show remarkable combination of chemo- and photodynamic activities, suggesting a promising drug nanocarrier.

The objective of this work is to prepare and characterize composite membrane using responsive nanoparticles into a polymer...
متن کاملPoly (methacrylic acid-co-acrylic acid)-grafted polyvinylpyrrolidone coated Magnetic nanoparticles as a pH-responsive magnetic Nano-carrier for controlled delivery of antibiotics
Objective(s): Pharmaceutical industries are leading to improved medications that can target diseases more effectively and precisely. Researchers have intended to reformulate drugs so that they may be more safely used in human body. The more targeted a drug is, the lower its chance of triggering drug resistance, a cautionary concern surrounding the use of broad-spectrum antibiotics. The aim of t...
متن کاملA dual-responsive supra-amphiphile based on a water-soluble pillar[7]arene and a naphthalene diimide-containing guest.
A dual-responsive supra-amphiphile was firstly constructed based on a water-soluble pillar[7]arene and a naphthalene diimide-containing guest with a long alkyl chain and a trimethylammonium group. The morphologies of the self-assembly formed from this supra-amphiphile could be adjusted by changing solution pH or adding α-cyclodextrin.
