CDC25 phosphatases are key cell cycle regulators and represent very attractive but challenging targets for anticancer drug discovery. Here, we explored whether fragment-based screening represents a valid approach to identify inhibitors of CDC25B. This resulted in identification of 2-fluoro-4-hydroxybenzonitrile, which directly binds to the catalytic domain(More)
Ca2+ entry blockers riodipine, D-cis-diltiazem and verapamil, when administered i.p. to rats at a dose of 10 mg/kg, produced two-fold decreases in the density of 1,4-dihydropyridine (DHP) receptors in rat cerebral cortex, as revealed by Scatchard plot analysis of radioligand binding made 24 h after the first injection. Thereafter, the number of DHP binding(More)
Administration of Ca-entry blockers with different chemical structure before the braining sessions produced the reduction of memory retention in mice and rats in the one-trial passive avoidance tests. This effect was absent in animals treated immediately after training test. Nootropic drugs piracetam and oxiracetam corrected the retention of memory when(More)
