A Convenient Strategy to Access Diverse Libraries of Amphiphilic Compounds Based on Glycopeptoids

Chirality, Volume 38, Issue 7, July 2026.
A synthetic platform based on a convergent synthetic strategy enables rapid access to a diverse amphiphilic glycopeptoids library. These modular systems exhibit self‐assembly into nanoscale aggregates, highlighting their potential as customizable platforms for drug delivery, biomimetic materials, and membrane protein stabilization.

Differential effects of lipid composition on the thermal and functional properties of membrane associated CYP2J2

Protein Science, Volume 35, Issue 7, July 2026.
Abstract CYP2J2 is a membrane‐bound cytochrome P450 that is expressed in cardiomyocytes, where it is known to metabolize arachidonic acid into cardioprotective epoxyeicosatrienoic acids (EETs). It consists of transmembrane domains embedded in the hydrophobic segments of the cell membrane and surrounded by various lipids.

N‐Glycosyl Triazoline Glycomimetics via Huisgen Cycloaddition With an Electron‐Deficient Alkene and BF3‐Catalysed Triazoline Fragmentation to Aziridines

European Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
Glycomimetics with triazoline and aziridine groups were synthesised via diastereoselective Huisgen cycloaddition from glycosyl azides. Density functional theory was applied to define the mechanism for BF3 promoted aziridine formation. Triazoline and aziridine derivatives were synthesised by diastereo‐ and regioselective Huisgen cycloaddition of 2,3,4,6‐

Synthesis of a C‐2 Functionalized l‐Iduronic Acid Derivative as a Candidate Pharmacological Chaperone for MPS II (Hunter Syndrome)

Chemistry – An Asian Journal, Volume 21, Issue 11, 15 June 2026.
A C‐2 functionalized l‐iduronic acid derivative was designed and synthesized as a candidate pharmacological chaperone for iduronate‐2‐sulfatase (IDS), the enzyme involved in the lysosomal storage disease MPS II (Hunter syndrome). The synthesis overcomes significant synthetic challenges associated with manipulations of L‐ido scaffolds.
