On why cancer cells require a great amount of glucose

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract The traditional thinking has been that cancer cells require a great amount of glucose to support their rapid growth, but the reality may be different. We have previously demonstrated that all cancer cells in The Cancer Genome Atlas harbor persistent Fenton reactions in their cytosol, which generate OH− ${\text{OH}}^{-}$ and ultimately kill the

Engineering a Bifunctional Fusion Purine/Pyrimidine Nucleoside Phosphorylase for the Production of Nucleoside Analogs

Biomolecules
Nucleoside phosphorylases (NPs) are pivotal enzymes in the salvage pathway, catalyzing the reversible phosphorolysis of nucleosides to produce nucleobases and α-D-ribose 1-phosphate.

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Phosphonated Carbocyclic 2'-Oxa-3'-azanucleosides as New Antiretroviral Agents [PDF]

, 2007
Phosphonated carbocyclic 2¢-oxa-3¢-azanucleosides have been synthesized and tested for their antiretroviral activity. The obtained results have shown that some of the compounds were as powerful as azydothymidine in inhibiting the reverse transcriptase ...

Novel drugs approved by the EMA, the FDA and the MHRA in 2025: A year in review

British Journal of Pharmacology, Volume 183, Issue 9, Page 1779-1813, May 2026.
Abstract In the 2025 novel drug mini‐review, one can take a full measure of the ingenuity that underlies current drug design and development, despite the year's smaller harvest (46 novel drugs) compared to 2024 (53) and 2023 (70). 54% of the novel drugs are first‐in‐class (FIC).
