Enhanced Photocatalytic H2O2 Production on Terpyridine‐Based Acrylonitrile‐Linked Covalent Organic Frameworks with Asymmetric Localized Electron Distribution

Advanced Materials, EarlyView.
Asymmetric localized electron distribution has been optimized in covalent organic frameworks to enhance *O2 adsorption and facilitate charge transfer, boosting photocatalytic two‐electron transfer oxygen reduction toward H2O2 production from water and air.

Postsynthetic Covalent Modification in Covalent Organic Frameworks

Israel Journal of Chemistry, 2018
AbstractThe modification of covalent organic frameworks (COFs) based on postsynthetic covalent linkages is discussed in this review. In this strategy, the COF is preparedas scaffold and then assembled with functional groups with preservation of structural skeleton.

Covalent Surface Modification of Oxide Surfaces

Angewandte Chemie - International Edition, 2014
AbstractThe modification of surfaces by the deposition of a robust overlayer provides an excellent handle with which to tune the properties of a bulk substrate to those of interest. Such control over the surface properties becomes increasingly important with the continuing efforts at down‐sizing the active components in optoelectronic devices, and the ...

Covalent modification of DNA by daunorubicin

Cancer Chemotherapy and Pharmacology, 1993
Daunorubicin, a clinically useful antitumor agent, induces mammary adenocarcinoma in Sprague-Dawley rats. As part of an investigation of the mechanism of tumor induction by daunorubicin, the formation of daunorubicin-DNA adducts has been investigated by 32P-postlabeling assay.

The language of covalent histone modifications

Nature, 2000
Histone proteins and the nucleosomes they form with DNA are the fundamental building blocks of eukaryotic chromatin. A diverse array of post-translational modifications that often occur on tail domains of these proteins has been well documented. Although the function of these highly conserved modifications has remained elusive, converging biochemical ...

Reversible covalent modification of DNA

Archives of Biochemistry and Biophysics, 1974
The reaction of bromomethylbenzoyl esters of choline and dimethylaminoethanol with DNA and model compounds led predominantly to phosphotriester formation. In model compounds the phosphotriester formation was verified by uv spectrometry. The bromomethylbenzoyl cationic esters reacted with DNA at room temperature at neutral pH values.

Regulated covalent modifications of lipid A

Journal of Endotoxin Research, 2001
Regulated covalent modifications of lipid A are implicated in virulence of pathogenic Gram-negative bacteria. The Salmonella PhoP/PhoQ-activated gene pagP is required for resistance to cationic antimicrobial peptides and for biosynthesis of hepta-acylated lipid A species containing palmitate.
