A streamlined hybrid method for the measurement of absolute photodetachment and photodissociation cross-sections [PDF]

open access: yesarXiv
The absolute photodetachment cross-section characterizes the photostability of atomic and molecular anions against photodestruction by neutralization. The measurement of this quantity has been reported only for atomic and simple molecular ions. In 2006, Wester's group introduced a novel ion trap-based technique to measure the absolute photodetachment ...

Brassinin from Brassica campestris L. inhibits colorectal cancer by inducing p62/NRF2/GPX4‐regulated ferroptosis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
BSN suppresses the cell viability of colorectal cancer by inducing GPX4‐regulated ferroptosis. BSN may bind to NRF2 protein to inactivate the NRF2 signaling, inhibiting the expression of p62 and HO‐1. Abstract Background Indole phytoalexins, plant‐derived compounds present in cruciferous vegetables, have demonstrated anticancer properties.

Engineered Biocatalyst for Enantioselective Hydrazone Reduction

open access: yesAngewandte Chemie, EarlyView.
Here, we report the discovery and engineering of a hydrazone reductase (HRED) biocatalyst that promotes efficient reduction of protected hydrazones with exceptional stereocontrol. These biotransformations offer a sustainable strategy for synthesizing valuable chiral N─N containing products that are commonly found in pharmaceuticals and agrochemicals ...

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine

open access: yesAngewandte Chemie, EarlyView.
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
