Acidic eco-catalysts derived from coffee husks in the acetylation of glycerol

Tetrahedron Green Chem
The transformation of coffee husks into solid acid catalysts (eco-catalysts) was studied. The synthesis of the materials consisted of the elaboration of carbonaceous supports by thermal means [graphitic carbon (Cp) and biochar (Cc)], followed by ...

Identification of 2‐Substituted‐3‐Hydroxy‐2,3‐Dihydroquinazolin‐4(1H) Ones as Cell‐Active Inhibitors of KDM4A Lysine Demethylase

ChemMedChem, Volume 21, Issue 10, 27 May 2026.
A novel 3‐hydroxy‐2,3‐dihydroquinazolinone scaffold is identified as a cell‐active KDM4A inhibitor through an orthogonal screening cascade minimizing assay interference. Integrated biochemical, biophysical, and proteomic validation reveals compound 6i as a bona fide binder that increases H3K9 methylation in cells, highlighting both a promising ...

Intraparticle diffusion model to determine the intrinsic kinetics of ethyl levulinate synthesis promoted by Amberlyst-15

, 2020
Levulinic acid and its esters are considered very versatile chemical compounds used for a wide range of derivatives. Traditionally ethyl levulinate is synthesized in batch reactors, using homogeneous catalysts (H2SO4, H3PO4).
