A Modular Chemoenzymatic Cascade Simplifies Divergent Synthesis of Natural and Unnatural Benzylisoquinoline Alkaloids. [PDF]

Adv Sci (Weinh)
A simplified chemoenzymatic platform is designed to integrate an enzyme cascade with subsequent chemical steps, enabling the divergent production of diverse benzylisoquinoline alkaloids (BIAs). Demonstrating remarkable versatility and enantioselectivity, four distinct classes of BIAs are efficiently generated, in which the natural medicine papaverine ...

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Photocatalytic Cross‐Coupling of Phenols and Heteroaryl Halides With Machine Learning‐Guided Reaction Prediction

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

Peripheral κ opioid receptor in pain and inflammation: From molecular signalling and gene expression to drug discovery

British Journal of Pharmacology, Volume 183, Issue 17, Page 5157-5189, September 2026.
The κ opioid receptor (κ receptor, KOR) is a G protein‐coupled receptor with well established roles in analgesia and immune modulation. Although historically studied primarily in the central nervous system (CNS), growing evidence indicates that κ signalling in peripheral tissues plays an important role in regulating pain, inflammation and immune ...

A Golgi‐localized N‐methyltransferase and reversible aldo–keto reductases coordinate dual terminal routes in galanthamine biosynthesis

The Plant Journal, Volume 126, Issue 6, June 2026.
Significant Statement This study identifies LaTMT2, a Golgi‐localized N‐methyltransferase, and three reversible aldo–keto reductases (LaAKR1 and LaAKR3) as key enzymes coordinating the dual terminal routes of galanthamine biosynthesis in Leucojum aestivum.

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

European Journal of Organic Chemistry, Volume 29, Issue 20, 27 May 2026.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

Metabolome analyses of two varieties of Anhua dark tea

International Journal of Food Properties
We performed volatile and nonvolatile metabolome analysis of Zhuyeqi (Z) and Baihaozao (B) dark teas during three stages of tea processing: (1) after withering and kneading (S), (2) after pile-fermenting (M), and (3) during drying and second kneading (Z).

Dearomatization with Axial‐to‐Central Chirality Conversion

European Journal of Organic Chemistry, Volume 29, Issue 17, 5 May 2026.
Atropisomers are exciting synthetic targets with unique properties, which find applications in many fields of chemistry. However, considering them as substrates is not very frequent, notably in the context of dearomatization reaction. We wish to discuss the different strategies for the dearomatization of aromatic atropisomers with axial‐to‐central ...

Multi‐Target Mechanisms of Moroccan Aphrodisiac Plants: An Integrative Computational and Phytochemical Investigation

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Moroccan medicinal plants with in silico‐approved aphrodisiac effects provide 94 phytochemicals. Docking against PDE5, AR, ERα, and aromatase gives top scores for lutein (−10.6), baicalein (−9.5), liquiritigenin (−9.2), and procyanidins (−9.7). ADMET filtering passes baicalein and liquiritigenin but excludes lutein and procyanidins. MD simulations (200
