Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

Emetine and Its Derivatives as Anticancer Agents Targeting the PI3K/AKT/mTOR Pathway: A Narrative Review of Mechanisms, Pharmacology, and Clinical Insights

Journal of Cellular and Molecular Medicine, Volume 30, Issue 16, August 2026.
ABSTRACT Emetine (EMT), a naturally occurring tetrahydroisoquinoline alkaloid, shows diverse biological actions, including anticancer effects. Despite existing studies, the role of EMT derivatives in cancer, particularly in relation to the PI3K/AKT/mTOR signalling pathway, remains largely underexplored.
