Dimerisation of nitrile oxides: a quantum-chemical study

open access: yes, 2009
The [3 + 2] and [3 + 3] cyclodimerisation processes of small nitrile oxides, XCNO (X = F, Cl, Br, CN, CH3) are investigated by ab initio coupled cluster theory at the CCSD, CCSD(T) and MR-AQCC levels for the first time.

Prmt6 Deficiency or Inhibition Restores Microglial Homeostasis and Promotes Scar‐Limited Repair in Adult Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
After spinal cord injury, adult microglia remain persistently activated with chronic PRMT6 (protein arginine methyltransferase 6) upregulation. Prmt6 deficiency or inhibition reestablishes microglial homeostasis and promotes a scar‐limited repairment, enhancing axonal regrowth.

Introduction of an isoxazoline unit to the β-position of porphyrin via regioselective 1,3-dipolar cycloaddition reaction

open access: yesBeilstein Journal of Organic Chemistry, 2019
Isoxazoline-linked porphyrins have been synthesized by a regioselective 1,3-dipolar cycloaddition reaction between vinylporphyrin 2 and nitrile oxides. The steric interaction directed the reaction trajectory, in which only the product with a link between

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition

open access: yesAdvanced Science, EarlyView.
In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.

Ion–molecule reactions between ionized nitrile oxides and neutral nitrile

open access: yesInternational Journal of Mass Spectrometry, 2002
Abstract The ion–molecule reactions of ionized nitrile oxide, RCN + O , with several neutral nitriles have been studied using both tandem mass spectrometric techniques and ab initio molecular orbital calculations. Ionized oxygen atom transfer as well as a formal substitution of nitric oxide by the neutral reagent in the radical cation were the ...

Orchestrated Engineered Polyphenol‐Peptide Condensates Coupled With β‐GP Reverses Diabetic Osteoporosis by Remodeling Mitophagy

open access: yesAdvanced Science, EarlyView.
A multifunctional β‐GP@EGCG‐E7 nanoplatform is engineered by polyphenol–peptide condensation and phosphate loading. Bone‐targeted delivery, antioxidant and anti‐inflammatory activity, and mitophagy restoration are integrated in one system, enabling protection of osteoblasts and endothelial cells and promoting bone regeneration under diabetic ...
