The synthesis and Gly/NMDA, AMPA and KA receptor binding activities of some 3-hydroxy-quinazoline-2,4-dione derivatives are reported. The binding data, together with functional antagonism studies, showed that the 3-hydroxy-quinazoline-2,4-dione moiety can be considered a useful scaffold to obtain selective Gly/NMDA and AMPA receptor antagonists. In fact, introduction of chlorine atom(s) on precise position(s) of the benzofused moiety yielded Gly/NMDA selective antagonists, while the presence of the 6-(1,2,4-triazol-4-yl) group shifted the affinity and selectivity towards the AMPA receptor.

In this paper, we describe the discovery of the 3-hydroxyquinazoline-2,4-dione as a useful scaffold to obtain potent inhibitors of the tumor-associated human carbonic anhydrases (hCAs) IX and XII. A set of derivatives (1–29), bearing different substituents on the fused benzo ring (Cl, NO2, NH2, CF3, ureido, amido, heterocycles), were synthesized, and several of them showed nanomolar activity in inhibiting
