Ethynyl‐Bridged Bis‐quinolinium Dyes: Studies of the Dependence of Different Types of Conjugation on Spectroscopic Properties

open access: yesEuropean Journal of Organic Chemistry, Volume 2022, Issue 47, December 19, 2022., 2022
Bis‐quinolinium salts are presented, the positive charges of which are combined by different types of conjugation. These result in characteristic differences in the LUMO geometries, charge distributions according to the rules of resonance as well as in UV/Vis and 13C NMR spectroscopic properties. The resonance frequencies of the triple bond can be used

Special Collection: Women of Catalysis 2024   NADH Driven Enzymatic Carboxylic Acid Reduction

open access: yesChemCatChem, Accepted Article.
Carboxylic acid reductases (CARs) are versatile biocatalysts for aldehyde production from carboxylic acids. The redox co‐factor utilized by CARs is NADPH and no explicitly NADH dependent CARs have been described so far. Especially in view of cell free applications which necessitate cofactor recycling, NADH dependent enzymes are more appealing due to ...

Mitochondria‐Catalyzed Activation of Anticancer Prodrugs

open access: yesChemCatChem, Accepted Article.
Mitochondria mediate electron transport chain (ETC) to power ATP synthase. In cancer cells, the ETC is disturbed leading to leakage of electron that ultimately results in generation of H2O2. This difference between cancer and healthy cells can be used for the design of cancer‐specific prodrugs as confirmed in several proof‐of‐concept studies ...
