A Modular Nucleoside Kinase Cascade for the Synthesis of Ribonucleoside Triphosphates

Biotechnology and Bioengineering, EarlyView.
Damm et al. report standardized enzymatic cascades for production of all canonical nucleoside triphosphates from the corresponding nucleosides, using kinase‐catalyzed phosphorylation from acetyl phosphate. Reactions afforded ∼ 100 mM product in near‐quantitative conversion.

Exploration of structure–activity relationship of 2,4‐diaminopyrimidine derivatives as hematopoietic progenitor kinase 1 inhibitors

Bulletin of the Korean Chemical Society, EarlyView.
Targeting HPK1 is a promising strategy to restore T‐cell anti‐tumor immunity. We report the design and synthesis of novel 2,4‐diaminopyrimidine derivatives, focusing on systematic structure–activity relationship (SAR) analysis These findings identify key structural features for potent HPK1 inhibition, facilitating the discovery of next‐generation ...

DNA Backbone Conformation in Cis-Syn Pyrimidine[ ]Pyrimidine Cyclobutane Dimers

, 1980
A theoretical calculation involving minimization of energy functions was made to determine the conformation of a deoxydinucleoside monophosphate pyrimidine[ ]pyrimidine cis-syn cyclobutane dimer. Such single-stranded moieties are useful models for the in

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris

Biological Diversity, EarlyView.
Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...
