1,3‐Diazetidin‐2‐Ones: Synthetic Approaches and Therapeutic Promise within the Aza‐β‐Lactam Family

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 43, November 24, 2025.
This review explores the synthesis, reactivity, and therapeutic potential of 1,3‐diazetidin‐2‐ones—an underexplored class of aza‐β‐lactams. Emphasis is placed on synthetic challenges, emerging methodologies, and their promise as β‐lactamase‐resistant scaffolds in medicinal chemistry. 1,3‐diazetidin‐2‐ones, overlooked members of the aza‐β‐lactam family,

Docking and Molecular Dynamics Simulation‐Based Analysis of Advanced Small‐Molecule Kinase Inhibitors Identified pre‐let‐7 miRNA Binders

open access: yesChemBioChem, Volume 26, Issue 22, November 17, 2025.
An integrated computational approach evaluating the binding between pre‐let‐7 microRNA and small‐molecule kinase inhibitors (SMKIs) revealed varied pre‐let‐7 binding affinities among the advanced SMKIs. The results justified the characterization of potential RNA targets for kinase inhibitors and small molecules with protein targets in general.

Using a Supramolecular Approach to Engineer Modular Hydrogel Platforms for Culturing Protoplasts – from General Tissue Engineering to Cellular Agriculture

open access: yesAdvanced Biology, Volume 9, Issue 11, November 2025.
Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular

Expression of a malarial Hsp70 improves defects in chaperone-dependent activities in ssa1 mutant yeast [PDF]

open access: yes, 2011
Plasmodium falciparum causes the most virulent form of malaria and encodes a large number of molecular chaperones. Because the parasite encounters radically different environments during its lifecycle, many members of this chaperone ensemble may be ...
