Identification of Key Residues for Enzymatic Carboxylate Reduction

open access: yesFrontiers in Microbiology, 2018
Carboxylate reductases (CARs, E.C. 1.2.1.30) generate aldehydes from their corresponding carboxylic acid with high selectivity. Little is known about the structure of CARs and their catalytically important amino acid residues.

ALDH2 mediates 5-nitrofuran activity in multiple species [PDF]

open access: yes, 2012
Understanding how drugs work in vivo is critical for drug design and for maximizing the potential of currently available drugs. 5-nitrofurans are a class of pro-drugs widely used to treat bacterial and trypanosome infections, but despite relative ...

Aldehyde-mediated inhibition of asparagine biosynthesis has implications for diabetes and alcoholism

open access: yes
Patients with alcoholism and type 2 diabetes manifest altered metabolism, including elevated aldehyde levels and unusually low asparagine levels. We show that asparagine synthetase B (ASNS), the only human asparagine-forming enzyme, is inhibited by ...

RuCl3·3H2O Catalyzed Reactions: Facile Synthesis of Bis(indolyl)methanes under Mild Conditions

open access: yesMolecules, 2011
RuCl3·3H2O was found to be an effective catalyst for reactions of indoles, 2-methylthiophene, and 2-methylfuran with aldehydes to afford the corresponding bis(indolyl)methanes, bis(thienyl)methanes, and bis(fur-2-yl)methanes in moderate to excellent ...

Copper-catalyzed enantioselective conjugate addition of organometallic reagents to challenging Michael acceptors

open access: yesBeilstein Journal of Organic Chemistry, 2020
The copper-catalyzed enantioselective conjugate addition (ECA) of organometallic nucleophiles to electron-deficient alkenes (Michael acceptors) represents an efficient and attractive methodology for providing a wide range of relevant chiral molecules. In

Chiral Aldehyde Catalysis Enables Direct Asymmetric Substitution Reaction of N-Unprotected Amino Acids with Halohydrocarbons [PDF]

open access: yes, 2023
The direct catalytic hydrocarbylation of readily available amino acids with halohydrocarbons is one of the most straightforward methods leading to disubstituted non-proteinogenic amino acid compounds.

1,3-Dipolar Cycloaddition Reactions of Azomethine Ylides with Carbonyl Dipolarophiles Yielding Oxazolidine Derivatives

open access: yesMolecules, 2016
We provide a comprehensive account of the 1,3-dipolar cycloaddition reactions of azomethine ylides with carbonyl dipolarophiles. Many different azomethine ylides have been studied, including stabilized and non-stabilized ylides.

A rapid, easy, and efficient method for synthesis of 4,4'-(arylmethylene)-bis-(1H-pyrazol-5-ols), catalyzed by boehmite nanoparticles [PDF]

open access: yesشیمی کاربردی روز, 2016
An efficient and eco-friendly method is introduced for the synthesis of 4,4'-(arylmethylene)-bis-(1H-pyrazol-5-ols) by the condensation reaction of two equivalents of 5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one with various aromatic aldehydes ...

Interaction of Amines with Ketone Aldehydes and Unsaturated Aldehydes [PDF]

open access: yesProceedings of the National Academy of Sciences, 1973
The optical changes occurring during the interaction of amines with ketone aldehydes or unsaturated aldehydes are accompanied by strong electron spin resonance signals, and can thus be explained as due to the transfer of one whole electron in the ground state.
