Reversible Thermoresponsive Host–Guest Binding of Pillar[n]arenes with Guest End-Functionalized Poly(2-n-Propyl-2-Oxazoline)s

Macromolecules, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 27, 2025

Host–guest based thermoresponsive supramolecular polymer assemblies have found significant interest in recent years as they provide unique opportunities for the reversible release of guest upon thermally controlled collapse polymer. However, reported systems are mostly on polyacrylamides and polyacrylates combination with positively charged cyclobis(paraquat-p-phenylene) host. To investigate whether such induced can be more generally developed, here we investigated thermoreversible host–guest association guest-functionalized poly(2-n-propyl-2-oxazoline) (PnPrOx) various pillar[n]arene hosts. Two types consisting a hydrophilic 4,4′-bipyridinium unit (PnPrOx-MV) or 5-aminopentanenitrile (PnPrOx-CN; introduced novel percarboxylato pillar[5/6]arenes) end-group were prepared. The complexation these PnPrOx water-soluble pillar[5/6]arenes containing anionic carboxylate groups (WP5 WP6) nonionic methoxytriethylene glycol (TP5 TP6) solubilizing was water. 1:1 complexes, i.e., WP6–PnPrOx-MV WP5–PnPrOx-CN, formed by electrostatic interactions at 283.15 K constants (3.84 ± 0.25) × 105 M–1 (0.96 0.04) 104 M–1, respectively. In contrast, TP5 TP6 only showed weak binding polymers. When heated above its cloud-point temperature, collapses precipitates due to effect lower critical solution temperature (LCST), which is demonstrated lead dissociation, providing thermal control over decomplexation WP5–PnPrOx-CN complexes. reversible, temperature-controlled threading dethreading process suggest potential applications sustainable separation recovery processes, well development smart materials temperature-responsive functionalities.

A new Light-Sensor system affecting cancer cells fate.

Biomaterials Research, Journal Year: 2025, Volume and Issue: 29

Published: Jan. 1, 2025

A new physiological photopolymerizing system with relevant effects on proteins and able to affect cancer cell fate was discovered here. The riboflavin-phosphocholine-light (RPL) induces lysozyme (LYZ) photopolymerization in vitro, affecting the viability of cells, both 2-dimensional 3-dimensional cultures. RPL treatment nontumoral, mesenchymal stem or cells shows a distinct behavior, depending ectopic presence LYZ. Morphological changes cellular aggregation were induced by treatment. phosphocholine high levels LYZ expression at breast cell-cell interface seems create vulnerability for this photodynamic under visible light exposure. Further, we generated 2 riboflavin-phosphocholine hydrogels (RPHy RPHy-LYZ) light-emitting diode transdifferentiation into osteoblast-like triple-negative line, embedded RPHy, detected, while death observed using RPHy-LYZ. Our results reveal properties potential translational implications linked study process therapeutical applications. highlight aspects molecular mechanism which riboflavin acts paving way use selective therapies system.
