Porous Phenazine‐bridged Tetraoxa[8]Circulenes for Selective Gold Recovery and Heterogeneous Catalysis

Angewandte Chemie, EarlyView.
Gold recycling from electronic waste using porous materials is an emerging concept to reduce the environmental impact of gold mining. In this work, we report the synthesis of a highly porous phenazine‐derived tetraoxa[8]circulene polymer and its utilization in gold capture and heterogeneous catalysis.

Synthesis and Spectroscopic Characterization of Selected Phenothiazines and Phenazines Rationalized Based on DFT Calculation

Molecules, 2022
Two unique structures were isolated from the phosphorylation reaction of 10H-phenothiazine. The 5,5-dimethyl-2-(10H-phenothiazin-10-yl)-1,3,2-dioxaphosphinane 2-oxide (2a) illustrates the product of N-phosphorylation of phenothiazine.

Multivalent Glycopolymer Design Unlocks Antimicrobial Activity of 2‐Deoxyglucose

Angewandte Chemie, EarlyView.
New approaches to combat antimicrobial‐resistant pathogens are needed. Here, scaffolding a nonmetabolizable sugar (2DG) on a polymer backbone is shown to significantly improve its antimicrobial activity. ABSTRACT With the increasing prevalence of multidrug‐resistant (MDR) pathogens, last‐line therapeutics such as cyclic peptides are insufficient ...

Mutational analysis of a phenazine biosynthetic gene cluster in Streptomyces anulatus 9663

Beilstein Journal of Organic Chemistry, 2012
The biosynthetic gene cluster for endophenazines, i.e., prenylated phenazines from Streptomyces anulatus 9663, was heterologously expressed in several engineered host strains derived from Streptomyces coelicolor M145.

Genetic and biochemical analyses of chromosome and plasmid gene homologues encoding ICL and ArCP domains in Vibrioanguillarum strain 775 [PDF]

, 2011
Anguibactin, the siderophore produced by Vibrio anguillarum 775 is synthesized from 2,3-dihydroxybenzoic acid (DHBA), cysteine and hydroxyhistamine via a nonribosomal peptide synthetase (NRPS) mechanism.

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

Effect of Producing Different Phenazines on Bacterial Fitness and Biological Control in Pseudomonas chlororaphis 30-84

The Plant Pathology Journal, 2018
Pseudomonas chlororaphis 30-84 is a biological control agent selected for its ability to suppress diseases caused by fungal pathogens. P. chlororaphis 30-84 produces three phenazines: phenazine-1-carboxylic acid (PCA), 2-hydroxy-phenazine-1-carboxylic ...

The Transcription Factor FgSge1 Harnesses the SAGA Complex to Activate Mycotoxin Biosynthesis and Fungal Virulence

Advanced Science, EarlyView.
This study reveals the molecular mechanism by which the transcription factor FgSge1 regulates mycotoxin biosynthesis and virulence in Fusarium graminearum. FgSge1 binds to the TAARGTTT cis‐element, enabling self‐activation. It recruits the SAGA complex, promotes histone acetylation, and facilitates jet‐like chromatin remodeling, thereby activating ...

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

Advanced Science, EarlyView.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.
