Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis
Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...

A microscopically assisted limited colectomy mouse model of early colon cancer
Establishment, surgery, and evaluation process of a microscope‐assisted limited colon resection mouse model for early‐stage colon cancer. Abstract Background Currently, there is a lack of an adequate rodent model for investigating surgical techniques and comprehensive treatment options for patients with colorectal cancer (CRC).

Bent N‐Heterocyclic Allenes From a Well‐Defined Titanium Vinylidene Complex
The syntheses and the structures of N‐heterocyclic allenes are reported. Allenes bearing fluorenylidene capping groups show markedly bent C═C═C units, a carbene‐like reactivity, and they can act as potent C‐donor ligands for metal complexes. ABSTRACT Allenes typically display a linear geometry. A notable exception occurs in allenes bearing two electron‐

Adenostemma lavenia, a traditionally used medicinal plant, has been employed to manage pain, inflammation, and circulatory issues. This study investigates the analgesic, anti‐inflammatory, and thrombolytic potentials of the acetone extract of A. lavenia leaves (AEAL) using in vivo, in vitro, and in silico methods.

Discovery of a Plant Pictet–Spenglerase With R‐Stereoselectivity
Strictosidine synthases (STRs) are plant Pictet–Spenglerases catalyzing the coupling of a secoiridoid with tryptamine. All previously characterized strictosidine synthases are strictly S‐selective. Here, we report the discovery of Epi‐STR, an R‐selective STR ortholog from the medicinal plant Pogonopus speciosus.

Cyclic diaryliodonium salts engage aryl Grignard reagents to trigger a self‐propagating aryne–arylation cycle. Transient cyclic triaryliodanes serve as aryne precursors and dynamic aryl reservoirs, delivering iodine‐capped teraryls with predominant meta‐selectivity. The preserved C─I bond enables outward π‐extension or inward recyclization.

A Revised Model for Muscarine Biosynthesis Involving Lysine Trimethylation
The fatal mushroom toxin l‐(+)‐muscarine is one of the most prominent natural products. We elucidated its biosynthetic origin in the sweating mushroom Collybia rivulosa based on incorporation of stable isotope‐labeled compounds and extensive mass spectrometric analyses.
