Iron-catalysed synthesis and chemical recycling of telechelic 1,3-enchained oligocyclobutanes

Closed-loop recycling offers the opportunity to mitigate plastic waste through reversible polymer construction and deconstruction. Although examples of chemical recycling of polymers are known, few have been applied to materials derived from abundant commodity olefinic monomers, which are the building blocks of ubiquitous plastic resins. Here we describe a [2+2] cycloaddition/oligomerization of 1,3-butadiene to yield a previously unrealized telechelic microstructure of (1,n ‘-divinyl)oligocyclobutane. This material is thermally stable, has stereoregular segments arising from chain-end control, and exhibits high crystallinity even at low molecular weight. Exposure of the oligocyclobutane to vacuum in the presence of the pyridine(diimine) iron precatalyst used to synthesize it resulted in deoligomerization to generate pristine butadiene, demonstrating a rare example of closed-loop chemical recycling of an oligomeric material derived from a commodity hydrocarbon feedstock.

A step forward in the development of superoxide dismutase mimetic nanozymes: the effect of the charge of the surface on antioxidant activity

Two binucleating hezaaza macrocycles containing a pyridinol spacer have been prepared and characterised. Protonation studies indicate the deprotonation of the phenol group at relatively low pH values with the concomitant occurrence of a keto-enolic equilibrium. These ligands readily form binuclear Cu2+ and Zn2+ complexes as denoted by potentiometric and spectroscopic studies. The binding of the metals yields to the ready deprotonation of the phenol with the stabilisation of the keto form that results in complexes of greater stabilities than the analogous ones containing pyridine as spacer instead of pyridine. Mixed Cu2+-Zn2+-complexes were also detected in aqueous solutions containing equimolar amounts of Cu2+, Zn2+ and ligands. The binuclear Cu2+ complexes show significant SOD activity as proved by the McCord-Fridovich assays. The binuclear Cu2+ complexes of the ligands grafted to boehmite nanoparticles (BNPs) show a remarkable increase in SOD activity, which reaches 8-fold in one of the systems. The observed increase can be ascribed to the positive zeta-potential of the BNPs since the same complexes anchored to silica nanoparticles with negative zeta-potential do not show any apparent increase in activity. This behaviour is reminiscent of the positively charged funnel found in CuZnSOD, which has the electroactive copper ion at its end.

Development of a novel class of peroxisome proliferator-activated receptor (PPAR) gamma ligands as an anticancer agent with a unique binding mode based on a non-thiazolidinedione scaffold

We previously identified dibenzooxepine derivative 1 as a potent PPAR. ligand with a unique binding mode owing to its non-thiazolidinedione scaffold. However, while 1 showed remarkably potent MKN-45 gastric cancer cell aggregation activity, an indicator of cancer differentiation-inducing activity induced by PPAR. activation, we recognized that 1 was metabolically unstable. In the present study, we identified a metabolically soft spot, and successfully discovered 3-fluoro dibenzooxepine derivative 9 with better metabolic stability. Further optimization provided imidazo[1,2-alpha]pyridine derivative 17, which showed potent MKN-45 gastric cancer cell aggregation activity and excellent PK profiles compared with 9. Compound 17 exerted a growth inhibitory effect on AsPC-1/AG1 pancreatic tumor in mice. Furthermore, the decrease in the hematocrit (an indicator of localized edema, a serious adverse effect of PPAR gamma ligands) was tolerable even with oral administration at 200 mg/kg in healthy mice.

B-Doped MnN4-G Nanosheets as Bifunctional Electrocatalysts for Both Oxygen Reduction and Oxygen Evolution Reactions

Non-platinum-group (NPG) single-metal-atom electrocatalysts with bifunctional catalytic capabilities for both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are highly sought for producing sustainable and renewable energy sources. Doping nonmetal atoms next to the active single-metal atom can be an effective way to further improve the overall catalytic activities, Herein, we report a nonmetal B-doping strategy for enhancing the catalytic activity of the graphene-based single-metal-atom Mn-pyridine-N-4-graphene catalysts [named MnN4Bn-G (n = 0-8)] toward ORR and OER The underlying chemical mechanism for this design is that the B dopant can lower the charge density corresponding to the d-orbital of the Mn atom, thereby weakening the adsorption strength of oxygen intermediates (O/OH/OOH) on the active Mn site, leading to higher ORR electrocatalytic activity. Not only can this doping strategy enhance ORR activity, but it can also retain high OER activity. Our results show that the MnN4B5-G catalyst entails both relatively high onset potential for ORR (u(onset) = 0.78 V) and relatively low overpotential for OER (eta(over) = 0.43 V), rendering it being a compelling oxygen redox bifunctional electrocatalyst. The newly designed single-metal-atom Mn-pyridine-N-4-graphene catalysts offer alternative NPG metals and bifunctional catalysts for renewable energy applications.
