Organocatalytic Enantioselective Addition of α‑Aminoalkyl Radicals to Isoquinolines

open access: yes, 2018
With a dual organocatalytic system involving a chiral phosphoric acid and a dicyanopyrazine-derived chromophore (DPZ) photosensitizer and under the irradiation with visible light, an enantioselective Minisci-type addition of α-amino acid-derived redox ...

Unveiling Gut Homeostasis Disruption in Sepsis: Towards an Integrated Mechanistic and Translational Roadmap

open access: yesCell Proliferation, EarlyView.
Elucidating the contribution of gut‐organ axes will provide new insights for developing combined therapeutic strategies against sepsis‐associated multiple organ dysfunction. ABSTRACT Sepsis, a life‐threatening clinical syndrome precipitated by a maladaptive host response to infection, is associated with substantial morbidity and high mortality rates ...

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

open access: yesPlant 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.

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

Insights Into the Origin and Local Adaptation Evolution of the Cultivated Sesame With Telomere‐to‐Telomere High‐Quality Genome

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Sesame (Sesamum indicum L., 2n = 26) is one of the oldest oilseed crops and is often called the ‘queen of oilseeds’ due to its high content of unsaturated fatty acids and natural antioxidants. Despite its long history, the origin and global spread of cultivated sesame remain unresolved.

Base-Promoted Synthesis of Isoquinolines through a Tandem Reaction of 2‑Methyl-arylaldehydes and Nitriles

open access: yes
A convenient method for preparing 3-aryl isoquinolines via a base-promoted tandem reaction is presented. Simply combining commercially available 2-methyl-arylaldehydes, benzonitriles, NaN(SiMe3)2, and Cs2CO3 enabled the synthesis of a variety of ...

Colon‐Targeted Berberine Nanoparticles‐Embedded Yeast Microcapsules for Regulation of Gut Immunity of Sepsis

open access: yeseFood, Volume 7, Issue 4, August 2026.
A schematic representation illustrating the preparation of BGNP@YM and its therapeutic effects on septic mice induced by lipopolysaccharide (LPS). (A) BBR is first encapsulated within GNPs to form BGNPs with anti‐inflammatory activity, which are subsequently coated with YM via chemical precipitation to obtain the BGNP@YM oral delivery system.
