Exploring Biological Properties of Manganese(II)‐Phenanthroline‐Based Complexes: In Vitro Insights

ChemistrySelect, Volume 11, Issue 29, 3 August 2026.
Four Mn(II) complexes with phenanthroline derivatives were studied. These compounds were tested against several parasites and different human cancer cells. Despite its cytotoxicity on breast cancer, DNA seems not to be the main biological target. These complexes can drive the design and development of new metal‐based agents with improved biological ...

Porphyromonas gingivalis Outer Membrane Vesicles‐Associated DNA Triggers Inflammation by Inducing IL‐6 in Astrocytes

Molecular Oral Microbiology, Volume 41, Issue 4, Page 227-238, August 2026.
Pg releases OMVs which contain Pg genomic DNA. The Pg OMVs‐associated DNA is incorporated into astrocytes via endocytosis and increases IL‐6 mRNA expression via TLR9. These effects of Pg OMVs may induce neuroinflammation, which could contribute to the onset and progression of AD in periodontal disease.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Boosting disassembly of π–π stacked supramolecular nanodrugs under tumor microenvironment by introducing stimuli‐responsive drug‐mates

Aggregate
Numerous reports have demonstrated the construction of supramolecular nanodrugs (SNDs) via the π–π stacking of drug molecules for antitumor applications because most drugs possess aromatic rings or other planar conjugate units.
