C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

open access: yesChemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Endothelial lipase: a new lipase on the block.

open access: yesJournal of lipid research, 2003
Endothelial lipase (EL) is a newly described member of the triglyceride lipase gene family. It has a considerable molecular homology with lipoprotein lipase (LPL) (44%) and hepatic lipase (HL) (41%). Unlike LPL and HL, this enzyme is synthesized by endothelial cells and functions at the site where it is synthesized. Furthermore, its tissue distribution

Redox Biocatalysis in Lidocaine‐Based Hydrophobic Deep Eutectic Solvents: Non‐Conventional Media Outperform Aqueous Conditions

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Two hydrophobic DESs, lidocaine/oleic acid and lidocaine/decanoic acid, were utilized as reaction media that were enzyme‐compatible and highly substrate‐solubilizer for carbonyl reduction catalyzed by horse liver alcohol dehydrogenase, focusing on the effect of water contents and on maximizing substrate loadings, which showcases for the first time the ...

A proteomic investigation of forebrain regeneration in the leopard gecko (Eublepharis macularius)

open access: yesDevelopmental Dynamics, EarlyView.
Our investigation reveals ontogenetic, injury‐ and regeneration‐associated proteomic changes in the leopard gecko forebrain. Abstract Background The ability to replace lost or damaged neurons following an injury is termed reactive neurogenesis. Although reactive neurogenesis has been reported in several lizard species, the molecular mechanisms ...

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]
