Experimenteller Nachweis der metallbezogenen Funktion eines Cyanobactins

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Patellamide (Cyanobactine) werden von einer cyanobakteriellen Spezies in grosser Menge hergestellt. Diese zyklischen Peptide wurden in der Vergangenheit fast ausschliesslich auf ihre cytotoxischen Eigenschaften untersucht. Wir diskutieren neue experimentelle Daten, die auf eine Metallionen‐abhängige biologische Funktion der Patellamide schliessen ...

Experimental Evidence for a Metal‐Related Function of a Cyanobactin

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.
Cyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.

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

open access: yesEuropean 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‐

Exploring Diverse Glycone Preferences of Aspergillus rutinosidases

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Rutinosidases from Aspergillus niger (AnRut) and A. oryzae (AoRut) catalyze hydrolysis and transglycosylation with non‐natural glycosides as donors, enabling glycosylation of alcoholic and phenolic acceptors. AnRut exhibits broad glycone promiscuity, while AoRut has a narrower substrate scope.
