Manipulation of Chemistry and Biology with Visible Light Using Tetra‐ortho‐Substituted Azobenzenes and Azonium Ions

open access: yesAngewandte Chemie, Volume 137, Issue 24, June 10, 2025.
Tetra‐ortho‐Azobenzenes (TOABs) in broad daylight: in recent years, TOAB photoswitches became indispensable tools for all‐visible‐light manipulation of chemistry, biology and materials. This review explores their unique photochemical properties, design and synthetic approaches, offering support in choosing a TOAB for a given application.

An adamantane‐based ligand as a novel chemical tool for thermosensory TRPM8 channel therapeutic modulation

open access: yesThe FEBS Journal, EarlyView.
Transient receptor potential cation channel subfamily M member 8 (TRPM8) is a cationic thermosensory channel crucial for cold sensation and menthol response. TRPM8 dysfunction leads to sensory symptoms such as cold allodynia. Targeting TRPM8 is important for treating diseases like peripheral neuropathies and cancer.

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine

open access: yesAngewandte Chemie, Volume 137, Issue 24, June 10, 2025.
19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals

Stereochemical insights into sarpagan and akuammiline alkaloid biosynthesis

open access: yesNew Phytologist, EarlyView.
Summary Sarpagan and akuammiline monoterpenoid indole alkaloids (MIAs) are a class of bioactive plant‐derived compounds with significant pharmaceutical potential. These alkaloids are formed through oxidative cyclization of geissoschizine, catalyzed by homologous cytochrome P450 monooxygenases (CYP) known as sarpagan bridge enzymes (SBEs) and rhazimal ...

The ins and outs of liver fat metabolism: The effect of phenotype and diet on risk of intrahepatic triglyceride accumulation

open access: yesExperimental Physiology, EarlyView.
Abstract In health, the liver is a metabolically flexible organ that plays a key role in regulating systemic lipid and glucose concentrations. There is a constant flux of fatty acids (FAs) to the liver from multiple sources, including adipose tissue, dietary, endogenously synthesized from non‐lipid precursors, intrahepatic lipid droplets and recycling ...
