Emerging Role of Ferroptosis in Diabetes and Associated Complications: When Metabolic Dysregulation Meets Cell Death

open access: yesCell Proliferation, Volume 59, Issue 5, May 2026.
This study identifies ferroptosis as a key driver of diabetes and its complications via iron metabolism and lipid peroxidation, elucidates organelle interactions underlying cell vulnerability, and provides insights for targeted therapies against metabolic disorders.

2-Oxo-2H-chromen-7-yl 3-methylbutanoate

open access: yesIUCrData
The title compound, C14H14O4, was synthesized by O-acylation of umbelliferone with isovaleryl chloride in the presence of diethyl ether as a solvent and pyridine as a base. The side chain moiety i.e.

Changes in cell ultrastructure and morphology of Arabidopsis thaliana roots after coumarins treatment

open access: yesActa Societatis Botanicorum Poloniae, 2014
The ultrastructure and morphology of roots treated with coumarin and umbelliferone as well as the reversibility of the coumarins effects caused by exogenous GA, were studied in Arabidopsis thaliana.

ACSL1‐Dependent Microglial Lipoimmunometabolic Reprogramming Underlies Cognitive Deficits in Alcohol Use Disorder

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
This study reveals that chronic alcohol exposure selectively upregulates ACSL1 expression in prefrontal cortical microglia, driving lipid metabolism reprogramming and lipid droplet accumulation, which activates the NLRP3 inflammasome and sustains neuroinflammation. To reverse this process, a dual‐targeted lipid nanoparticle, siACSL1@LNP‐MR, is designed

SYNTHESIS AND EVALUATION OF SOME UMBELLIFERONE DERIVATIVES AS ANTI-INFLAMMATORY AGENTS

open access: yes, 2018
Seventeen 7-hydroxy coumarin (umbelliferone) derivatives were synthesized in an almost quantitative yield via reaction with the corresponding ethylchloroacetate, p-substituted benzyl chloride, 2-bromoacetophenone or 2-chloroacetanilide in the presence of

Context‐Dependent Chemoselectivity of Aromatic C‐Methyltransferases

open access: yesChemBioChem, Volume 27, Issue 8, April 2026.
Chemoselectivity is context‐dependent: The SAM‐dependent C‐MTs SfmM2 and NapB5 from streptomycetes catalyze the C‐ and/or O‐dimethylation of aromatic substrates, including l‐tyrosine and flavonoids. C‐methylation activity requires precise substrate recognition and positioning to ensure proximity between the target carbon nucleophile and the methyl ...

Antifungal activity of davanone-type sesquiterpenes from Artemisia lobelii var. conescens [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
Five tetrahydrofuran sesquiterpenes, so-called davanones, and coumarin umbelliferone isolated from Artemisia lobelii All. var. canescens (DC.) Briqu, were tested for antifungal activity. All the compounds inhibited the growth of the applied fungi.

New fluorogenic probes for neutral and alkaline ceramidases

open access: yesJournal of Lipid Research, 2019
New fluorogenic ceramidase substrates derived from the N-acyl modification of our previously reported probes (RBM14) are reported. While none of the new probes were superior to the known RBM14C12 as acid ceramidase substrates, the corresponding nervonic ...
