The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Design, synthesis and activity evaluation of tetrahydroisoquinoline‐based programmed cell death ligand 1 inhibitors

Smart Molecules, EarlyView.
Based on a 3D‐quantitative structure‐activity relationship pharmacophore model, structural optimization of Y6 yielded Y7f. Mechanistic studies revealed that Y7f acted as a programmed death receptor 1/programmed cell death ligand 1 (PD‐L1) interaction inhibitor by inducing PD‐L1 dimerization. Y7f restored T‐cell function.

GMP‐compliant production, validation and dosimetry of clinical grade [18F]3‐(3‐fluoropropyl)‐2‐phenyl‐2,3‐dihydrobenzo[d]thiazole ([18F]FPBT) for oxidative stress PET imaging

British Journal of Pharmacology, EarlyView.
Background and Purpose Oxidative stress plays a critical role in the pathophysiology of various diseases, yet current methods for its non‐invasive detection remain limited. This study aimed to systematically validate a superoxide‐selective PET tracer, [18F]FPBT, for the early diagnosis and therapeutic monitoring of oxidative stress‐related conditions ...

The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

Journal of Integrative Plant Biology, EarlyView.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...
