Photocatalytic Three-Component Synthesis of 3‑Heteroarylbicyclo[1.1.1]pentane-1-acetates
Herein, we report a visible-light-induced three-component reaction involving [1.1.1]propellane, diazoates, and various heterocycles for the synthesis of 3-heteroarylbicyclo[1.1.1]pentane-1-acetates. Throughout this reaction, the radicals generated from

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Enzymatic Cleavage of Aryl Acetates
, 2016 Seven enzymes have been screened for the cleavage of aryl acetates. Phenyl and naphthyl acetates react with lipases and esterases, whereas the sterically demanding anthracene acetate gave a conversion only with porcine liver esterase and esterase 2 from ...

Mode of attack of hydriodic acid on unsaturated glyceryl ethers
Journal of Lipid Research, 1965 The mode of action of hydriodic acid (HI) on a sample rich in selachyl alcohol [1-O-9(cis)-octadecenyl glycerol] has been studied. HI attacked the olefinic bonds as well as the ether bonds, with the formation of at least two diiodides as well as the ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

DBU-mediated C-C bond formation between Baylis-Hillman acetates and active methylene compounds
225-231A new reagent system for the formation of C-C bond between the Baylis-Hillman acetates and active methylene compounds (AMCs) has been developed. This method provides tri-substituted alkenes as the major product in good yield under neat condition.

Cobalt-catalyzed carboxylation of propargyl acetates with carbon dioxide. [PDF]
, 2014 The cobalt-catalyzed carboxylation of propargyl acetates with CO2 (1 atm) is described. The reaction proceeds at room temperature in the presence of Mn powder as a reducing reagent. Various propargyl acetates are converted to the corresponding carboxylic
