Popis: Cell division cycle phosphatases CDC25 A, B and C are involved in modulating cell cycle processes and are found overexpressed in a large panel of cancer typology. Here, we describe the development of two novel quinone-polycycle series of CDC25A and C inhibitors on the one hand 1a-k, coumarin-based, and on the other 2a-g, quinolinone-based, which inhibit either enzymes up to a sub-micro molar level and at single-digit micro molar concentrations, respectively. When tested in six different cancer cell lines, compound 2c displayed the highest efficacy to arrest cell viability, showing in almost all cell lines sub-micro molar IC50 values, a profile even better than the reference compound NCS95397. To investigate the putative binding mode of the inhibitors and to develop quantitative structure-activity relationships, molecular docking and 3-D QSAR studies were also carried out. Four selected inhibitors, 1a, 1d, 2a and 2c have been also tested in A431 cancer cells; among them, compound 2c was the most potent one leading to cell proliferation arrest and decreased CDC25C protein levels together with its splicing variant. Compound 2c displayed increased phosphorylation levels of histone H3, induction of PARP and caspase 3 cleavage, highlighting its contribution to cell death through pro-apoptotic effects.
