Moreover, the facilitation in processing sensory information (priming effects) presented at the cued spatial location occurs even before the onset of the oculomotor response, suggesting that covert attention is present before 4 months of age. Overall, this study highlights how ERPs method could help researchers at investigating the neural basis of attentional mechanisms in infants. A new series of pyrimidine derivatives as human carbonic anhydrases (CA, EC 4.2.1.1) inhibitors is here designed by including a 5-fluorouracil (5-FU) moiety, broadly used anticancer medication, in nitrogenous base modulators of the tumor-associated CAs. Most sulfonamide derivatives efficiently inhibit the target CA IX (KIs in the range 0.47-44.7 nM) and CA XII (KIs in the range 2.9-83.1 nM), while the 5-FU coumarin derivatives showed a potent and totally selective inhibitory action against the target CA IX/XII over off-target CA I/II. The X-ray solved crystal structure of CA II in adduct with a representative uracil derivative provided insights on the binding mode to the target of such pyrimidine derivatives. On the basis of potency and selectivity inhibition profiles, coumarin 12a, the sulfonamide CAIs showing the greatest II/IX specificity (4e, 6b and 6d) and the unique subnanomolar CA IX inhibitor 10a were tested in vitro for their antiproliferative action against a panel of eight cancer cell lines. The breast cancer cell lines MDA-MB-231 and T47D were the most susceptible with IC50 values in low to medium micromolar ranges (2.45 ± 0.07-18.86 ± 0.72 μM and 6.86 ± 0.31-40.92 ± 1.59 μM, respectively). A cell cycle analysis showed that 4e and 6d arrest T-47D cells mainly in the G2/M phase. Using an annexin V-FITC apoptosis assay, 4e and 6d were shown to induce a
