Catalytic Scalable Synthesis of Polyketides Enabled by Chiral Brønsted Acid‐Catalyzed Asymmetric Allylborations

The Chemical Record, EarlyView.
The scalable synthesis of target molecules is crucial for applications such as biological evaluation in medicinal chemistry and even industrial production. We described recent advances in chiral Brønsted acid–catalyzed asymmetric allylboration, which enables access to previously elusive chiral building blocks, and highlight its application to the ...

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

Plant Biotechnology Journal, EarlyView.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

Hexahydroquinoline Featuring Amide Functionality: A Promising Scaffold With Calcium Channel Blocking Activity

Drug Development Research, Volume 87, Issue 2, April 2026.
ABSTRACT Hexahydroquinoline (HHQ) is a widely recognized scaffold that has garnered considerable attention owing to its diverse pharmacological properties. The structure of HHQ includes a 1,4‐dihydropyridine (DHP) ring, which serves as the pharmacophore for the predominant class of drugs known as calcium channel blockers.
