Simultaneous Analysis of Antihyperlipidemic Drug Combinations by Green High‐Performance Liquid Chromatography Using Design of Experiments

SEPARATION SCIENCE PLUS, Volume 9, Issue 7, July 2026.
ABSTRACT Cardiovascular diseases are the leading cause of worldwide mortality, often supported by intricate dyslipidemic patterns of high levels of low‐density lipoprotein cholesterol and triacylglycerol. HMG‐CoA reductase inhibitors (statins) and ezetimibe can be used synergistically to treat these pathologies, as they target distinct metabolic ...

A General Strategy for the Synthesis of Jerangolids Enabled by π‐allyl Stille Coupling

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
A general strategy for the synthesis of jerangolids is established, featuring a late‐stage π‐allyl Stille coupling of two advanced, highly customizable building blocks to form the skipped diene core. The approach provides access to all naturally occurring jerangolids, including jerangolid H, whose configuration is confirmed by NMR analysis.

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.
