The influence of iron-binding ligands in the corrosion of carbon steel driven by iron-reducing bacteria

npj Materials Degradation, 2022
Iron reducing bacteria (IRB) are thought to accelerate the corrosion of steel by removing the Fe(III)-oxide passivating layer through iron respiration.

Genomic characterization of malonate positive Cronobacter sakazakii serotype O:2, sequence type 64 strains, isolated from clinical, food, and environment samples

Gut Pathogens, 2018
Background Malonate utilization, an important differential trait, well recognized as being possessed by six of the seven Cronobacter species is thought to be largely absent in Cronobacter sakazakii (Csak). The current study provides experimental evidence

Nucleophilic Addition to (3-Methylpentadienyl)iron(1+) Cations: Counterion Control of Regioselectivity; Application to the Enantioselective Synthesis of 4,5-Disubstituted Cyclohexenones [PDF]

, 2006
The regioselectivity of malonate addition to (3-methylpentadienyl)Fe(CO)3+ is controlled by the malonate−counterion association. The Li+ salt of malonate proceeds via C1 nucleophilic attack to afford the 1,3Z-diene complex 4a, while reaction of highly ...

Synergistic Visible Light Nanophotocatalysis and Asymmetric Organocatalysis for the Stereoselective α‐Alkylation of Aldehydes

Advanced Synthesis &Catalysis, EarlyView.
An unprecedent dual catalytic nanophotocatalytic and asymmetric organocatalytic system for the α‐functionalization of aldehydes is developed using carbon nanodots as photosensitizers. The optimized methodology yields the alkylated products with up to 94% yield and up to 98:2 e.r., evidencing the possible recycling of the nanocatalysts.

Trypanocidal action of bisphosphonium salts through a mitochondrial target in bloodstream form Trypanosoma brucei [PDF]

, 2015
Lipophilic bisphosphonium salts are among the most promising antiprotozoal leads currently under investigation. As part of their preclinical evaluation we here report on their mode of action against African trypanosomes, the etiological agents of ...

Inhibiting FAT1 Blocks Metabolic Bypass to Enhance Antitumor Efficacy of TCA Cycle Inhibition through Suppressing CPT1A‐Dependent Fatty Acid Oxidation

Advanced Science, EarlyView.
This study demonstrates that mutant FAT1 promotes ASCL2‐driven, CPT1A‐dependent fatty acid oxidation, leading to resistance to CPI‐613‐mediated TCA cycle inhibition in head and neck cancer. In vivo gene depletion of mutant FAT1 with LNP‐sgFAT1 suppresses tumor growth and restores CPI‐613 sensitivity, revealing a targetable metabolic bypass with ...

Preparation, Characterization and Reactivity of (3-Methylpentadienyl)iron(1+) Cations [PDF]

, 2007
The title cations (9 and 12) were prepared by dehydration of (3-methyl-2,4-pentadien-1-ol)Fe(CO)2L+ complexes. The structure of the (CO)2PPh3-ligated 12 was determined by single-crystal X-ray analysis. Reaction of carbon and heteroatom nucleophiles to (3-
