Efficient encapsulation of insulin by a giant macrocycle as a powerful approach to the inhibition of its fibrillation.

Diabetes is a lifelong metabolic disease that requires frequent subcutaneous injections of insulin. However, free insulin is prone to forming immunogenic fibrillar aggregates under physiologic conditions, which limits its biomedical applications. Here, an approach to inhibiting insulin fibrils was developed through entire encapsulation by a giant macrocyclic inhibitor agent.

Porous pillar[6]arene-based polymers for reversible iodine capture.

Iodine in nuclear waste can cause serious environment pollution and health risks, and has thus driven more development of materials for iodine capture. Herein, a novel porous pillar[6]arene-based polymer (P-P6APs) was easily prepared as a supramolecular adsorbent for iodine a one-step crosslinking reaction between per-hydroxylated pillar[6]arene and decafluorobiphenyl. Nitrogen adsorption tests demonstrated that this material possessed a satisfactory surface area ( = 366 m g) and pore diameter (3.

Enhancing the quantum yield of singlet oxygen: photocatalytic degradation of mustard gas simulant 2-chloroethyl ethyl sulfide catalyzed by a hybrid of polyhydroxyl aluminum cations and porphyrin anions.

By combining the anionic salt meso-tetra(4-carboxyphenyl)porphyrin (TCPP) and the Keggin polyoxometalate cation cluster [AlO(OH)(HO)] a simple ion-exchange method, a hybrid (CHNO)[AlO(OH)(HO)](OH)·18HO (Al-TCPP) was prepared and thoroughly characterized as a prototype of polyoxometalate-porphyrin hybrids for the photocatalytic degradation of the mustard gas simulant 2-chloroethyl ethyl sulfide (CEES). The experimental results showed that the catalytic degradation rate of CEES in the presence of Al-TCPP reached 96.16 and 99.

Synergistic enhancement of the emergency treatment effect of organophosphate poisoning by a supramolecular strategy.

Poisoning by organophosphorus agents (OPs) is a serious public health issue across the world. These compounds irreversibly inhibit acetylcholinesterase (AChE), resulting in the accumulation of acetylcholine (ACh) and overstimulation of ACh receptors. A supramolecular detoxification system (SDS) has been designed with a view to deliver pyridine-2-aldoxime methochloride (PAM) with a synergistic inhibition effect on the ACh-induced hyperstimulation through host-guest encapsulation.
