Enzymatically Triggered, Isothermally Responsive Polymers: Reprogramming Poly(oligoethylene glycols) To Respond to Phosphatase.
Polymers which can respond to externally applied stimuli have found much application in the biomedical field due to their (reversible) coil-globule transitions. Polymers displaying a lower critical solution temperature are the most commonly used, but for blood-borne (i.e., soluble) biomedical applications the application of heat is not always possible, nor practical. Here we report the design a...
متن کاملEncapsulation of oligoethylene glycols and perfluoro-n-alkanes in a cylindrical host molecule.
Oligoethylene glycols and perfluoro-n-alkanes are suitable guests for the synthetic cylindrical host molecule 1(2); an investigation of these host-guest systems is reported.
متن کاملNewly characterized interaction stabilizes DNA structure: oligoethylene glycols stabilize G-quadruplexes CH–π interactions
Oligoethylene glycols are used as crowding agents in experiments that aim to understand the effects of intracellular environments on DNAs. Moreover, DNAs with covalently attached oligoethylene glycols are used as cargo carriers for drug delivery systems. To investigate how oligoethylene glycols interact with DNAs, we incorporated deoxythymidine modified with oligoethylene glycols of different l...
متن کاملLow toxic, thermoresponsive dendrimers based on oligoethylene glycols with sharp and fully reversible phase transitions.
Novel first (G1) and second (G2) generation dendrimers based on three-fold branched oligoethylene glycol dendrons are efficiently synthesized which show characteristic thermoresponsive behavior and negligible cytotoxicity (for G2).
متن کاملMethotrexate Nanoparticles Prepared with Codendrimer from Polyamidoamine (PAMAM) and Oligoethylene Glycols (OEG) Dendrons: Antitumor Efficacy in Vitro and in Vivo
The novel methotrexate-loaded nanoparticles (MTX/PGD NPs) prepared with amphiphilic codendrimer PGD from polyamidoamine and oligothylene glycol dendrons were obtained via antisolvent precipitation method augmented by ultrasonication. Based on the excellent hydrophility of PGD, the drug-loaded nanoparticles could be investigated easily with the high drug-loading content (~85.2%, w/w). The MTX/PG...
