Structural Elucidation and Engineering of the (S)‐scoulerine 2‐O‐Methyltransferase Enabling Regioselective Epiberberine Biosynthesis in Coptis chinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Protoberberine alkaloids are a characteristic group of natural products in Coptis plants known for their notable pharmacological activities. However, the structural similarity and the substrate promiscuity of their biosynthetic enzymes have left the precise synthetic pathways remain unclarified, posing challenges to regulate product formation.

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

AlkaPlorer: A database‐driven explorer for natural alkaloids and derivatives

Journal of Integrative Plant Biology, Volume 68, Issue 5, Page 1384-1398, May 2026.
The alkaloid database AlkaPlorer integrates over 130,000 compounds across 12,250 species. By linking chemical structures with biological and evolutionary data, it reveals how these molecules evolve and function. This platform serves as a vital resource for AI‐driven discovery in plant metabolism and modern drug development. ABSTRACT Alkaloids, renowned

Transaminase and Norcoclaurine Synthase One‐Pot Cascades Towards (1S)‐Tetrahydroisoquinolines

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
A TAm‐NCS cascade towards THIQs has been established, starting from amines with the in situ production of aldehydes. The cascade was used with a variety of nonfunctionalized and functionalized amines, and reaction conditions modified to enhance formation of the desired cross‐products.

Linking Metabolomic Diversity to Pharmacological Potency in Anonidium mannii Leaf Extracts

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study investigates the metabolomic profile and pharmacological activities of extracts from Anonidium mannii leaves. The extracts were profiled using an integrated LC‐MS/GC‐MS, and evaluated for antimicrobial, antioxidant and cytotoxic activities, providing a basis for future studies and validation in more advanced biological models.
