Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry
Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...

Metabolic abnormalities contribute to the pathogenesis of obesity and its complications. Yet, the understanding of the interactions between critical metabolic pathways that underlie obesity remains to be improved, in part owing to the lack of ...

Abstract DNA‐encoded libraries (DELs) enable large‐scale screening for hit identification, but accessing sp3‐rich, three‐dimensional chemotypes beyond flat, aromatic scaffolds remains challenging. Multicomponent reactions (MCRs) assemble such complexity from simple building blocks in a single step, and reaction‐engineering strategies have extended on ...

Photodimerization in pyrimidine-substituted dipeptides
Ten N-epsilon-glycylornithineamide derivatives have been synthesized containing various N-alpha-linked pyrimidine-1-ylacetyl groups which can undergo (2 pi + 2 pi) photodimerization on irradiation with UV light at 254 rim.

Biomimetic N‐cyano sulfoximine–thiazole ligation for antibody–drug conjugate assembly
Biomimetic N‐cyano sulfoximine–thiazole ligation is applied for the first time to antibody–drug conjugate assembly. Installation of a sulfoximine handle on trastuzumab followed by ligation with a cysteine‐functionalized payload affords model ADCs with tunable drug‐to‐antibody ratios of 2–8 under mild aqueous conditions.

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

Purification and properties of bacterial pyrimidine nucleosidase
The metabolism of pyrimidine nucleosides was found to be similar to the dissimilation of purine nucleosides. Thus pyrimidine base is cleaved from the nucleoside and is accumulated.

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

Elevated Expression of Pyrimidine Nucleoside Phosphorylase (PyNPase) in Renal Cell Carcinoma Tissue [PDF]
Background: Pyrimidine nucleoside phosphorylase (PyNPase) is an enzyme that converts 5'-deoxy-5-fluorouridine to 5- fluorouracil. PyNPase is identical to platelet-derived endothelial cell growth factor (PD-ECGF), and has angiogenic activity.
