Deferiprone as a Precision Iron-Stress Probe
2026-09-20
Deferiprone, also known as 3-hydroxy-1,2-dimethylpyridin-4-one, is more than an iron chelator: it is a tunable probe for linking iron availability to proliferation, metabolism, redox balance, and apoptosis. This article translates enterocyte metabolomics into practical assay design for cancer biology and neurovascular research.

SepM Mutations and S. mutans–S. gordonii Inhibition
2026-09-18
Liu et al. linked recurrent sepM missense mutations in clinical Streptococcus mutans isolates with stronger inhibition of Streptococcus gordonii and examined how selected substitutions alter SepM–CSP-21 binding. The work combines isolate-level genetics, expression analysis, recombinant protein studies, and pH-dependent affinity measurements to connect bacterial variation with interspecies competition.

IAM LC vs LEKC for Pulmonary Drug Permeability
2026-09-18
The reference study provides a direct comparison of immobilised artificial membrane liquid chromatography and liposome electrokinetic capillary chromatography for modelling drug–membrane partitioning and pulmonary permeability. Its results show that LEKC can better reflect phospholipid-mediated interactions and lung permeability, whereas IAM LC offers broader compound coverage, simpler operation, and stronger suitability for automated screening.

Two Flavone 2′-Glucosides from Scutellaria baicalensis
2026-09-17
The 1995 reference study established two previously unreported flavone 2′-O-glucosides from Scutellaria baicalensis roots and identified seven additional phenolics, including baicalin methyl ester. Its value is primarily phytochemical: chromatographic isolation and multidimensional spectral analysis authenticated structures that can now serve as starting points for mechanistic studies, while the paper itself did not test intestinal barrier activity or anti-inflammatory effects.

Anagliptin (SK-0403): DPP-4 and Vascular Mechanisms
2026-09-17
Anagliptin (SK-0403) is an orally active DPP-4 inhibitor with a reported IC50 of 3.8 nM. In rabbit aortic rings, the compound produced vasorelaxation associated with Kv channel and SERCA pump activity, while classic cyclic-nucleotide pathways and the endothelium were not required.

Iron Stress Reprograms Enterocyte Metabolism
2026-09-14
Navazesh and Ji used IPEC-J2 enterocytes to show that both iron deficiency and iron excess produce distinct metabolic and transcriptional programs. The study links iron deficiency to impaired proliferation, altered central carbon metabolism, and inflammatory signaling, while iron excess favors cholesterol synthesis and lowers alpha-tocopherol, with partial recovery after iron repletion.

BRD4–RAC1 Co-Targeting in Breast Cancer
2026-09-14
The reference study identifies combined BRD4 and RAC1 inhibition as a subtype-aware strategy that suppresses breast cancer growth, stemness, migration, and tumorigenesis. Its mechanistic contribution is the linkage of BRD4–RAC1 blockade to disruption of the c-MYC–G9a–FTH1 axis and downregulation of HDAC1, providing a useful framework for interpreting combination strategies in cancer epigenetics.
