The cell division cycle 25 (Cdc25) family of proteins are dual specificity phosphatases that activate cyclin-dependent kinase (CDK) complexes, which in turn regulate progression through the cell division cycle. Overexpression of Cdc25 proteins has been reported in a wide variety of cancers; their inhibition may thus represent a novel approach for the development of anticancer therapeutics. Herein we report new coumarin-based scaffolds endowed with a selective inhibition against Cdc25A and Cdc25C, being 6a and 6d the most efficient inhibitors and worthy of further investigation as anticancer agents.

Abstract Some new 4-(2,6-diarylpyridin-4-yl)-2H-chromen-2-one derivatives 5a–l have been synthesized by reacting 4-(3-oxo-3-arylprop-1-enyl)-2H-chromen-2-ones 3a–c with appropriate 1-(2-oxo-2-arylethyl)pyridinium bromide salt 4a–d in the presence of ammonium acetate in refluxing glacial acetic acid. The newly synthesized compounds have been characterized by elemental and spectral analysis. GRAPHICAL
