Harnessing Acoustic Cavitation Energy for the Selective Degradation of Impurities in Glucose Syrup

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
The energy released during the implosion of acoustic cavitation bubbles can be harnessed and selectively transferred to a target solute, enabling its specific decomposition without degrading other solutes present in the solution. This proof of concept was demonstrated in the degradation of impurities present in trace amount in glucose syrup.

Total Synthesis and Antimalarial Studies of Caelestines A–C

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
Total synthesis of caelestines A–C (alkaloids from the Australian ascidian, Aplidium caelestis) was accomplished, constituting the first synthesis of caelestines B and C. Caelestines A–C, with five other novel quinolones, were assessed against Plasmodium falciparum 3D7 and Dd2. Caelestine B was found to be a selective antimalarial alkaloid. Caelestines

Hofmann Degradation of Asparagine and Glutamine as an Efficient Approach for the Synthesis of Derivatized Lysine Homologs

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
A practical and scalable route to C1 and C2 lysine homologs has been developed using Hofmann degradation of N‐protected L‐asparagine and L‐glutamine as the key step. These short‐tether scaffolds enable efficient synthesis of diverse Fmoc‐protected noncanonical amino acids (ncAAs) bearing donor, acceptor, redox‐active, and fluorescent residues.

Exploring Diverse Glycone Preferences of Aspergillus rutinosidases

Advanced 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.
