Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study addresses significant process challenges associated with the reactive nature of hemicellulose‐derived furan intermediates in aqueous mediums. A continuous agitated cell reactor was used to intensify the extractive reaction using methyl isobutyl ketone as an extractive phase to isolate in situ the furan products obtained by ...

British Journal of Clinical Pharmacology, EarlyView.Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...

α‐Azaaryl carbonyl derivatives in stereodivergent catalytic reactions
Bulletin of the Korean Chemical Society, EarlyView.This review highlights recent progress in the catalytic synthesis of chiral azaarenes, focusing on α‐azaaryl carbonyl derivatives as versatile precursors. By leveraging chiral Lewis acid catalysis, stereodivergent reactions with diverse electrophiles enable precise construction of multi‐stereogenic azaarenes, offering new opportunities for advanced ...

Chemistry &Biodiversity, EarlyView.ABSTRACT Chemical investigation of Disynaphia filifolia (Hassl.) R.M. King & H. Rob. (Asteraceae) led to the isolation of eight compounds, with tremetone being the major metabolite recovered. Tremetone has been suggested as the toxic compound in Ageratina altissima and Isocoma pluriflora, two species of the Asteraceae family. Although D.

Chemistry &Biodiversity, EarlyView.The chemical analysis of aerial parts of the melliferous Viguiera dentata led to the isolation of 20 substances, including the new cycloartanes 24‐epi‐argentatin C, 7β‐hydroxy‐24‐epi‐argentatin C, 7β‐hydroxy‐argentatin B. In‐combo results indicated that specific argentatins and ent‐kaurenoic acids have the potential to control Spodoptera frugiperda ...
