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 the hCA IX and XII isoforms, while they were ineffective against the cytosolic enzymes hCAs I and II. Some selected compounds were tested for their antiproliferative activity against HT-29 colon cancer cell lines. After 48 h of treatment with the lower dose (30 μM), derivatives 12, 14, 15, and 19 were significantly active, inducing a mortality by about 50% in both normoxia and hypoxia. This finding led us to hypothesize for these compounds more than one mechanism of action involving both CAs IX and XII and other not yet identified target(s).

在本文中，我们描述了3-羟基喹唑啉-2,4-二酮作为获得与肿瘤相关的人类碳酸酐酶（hCAs）IX和XII的有效抑制剂的有用支架的发现。一组衍生物（1 - 29），轴承上的稠合苯并环不同的取代基（氯，NO 2，NH 2，CF 3基，脲基，酰氨基，杂环），合成，并在抑制其中几个显示纳摩尔活性hCA IX和XII亚型，尽管它们对细胞溶质酶hCAs I和II无效。测试了一些选择的化合物对HT-29结肠癌细胞系的抗增殖活性。用较低剂量（30μM）处理48小时后，衍生物12，14，15，和19分别为显著活性，约50％在两个常氧和低氧诱导的死亡率。这一发现使我们为这些化合物假设了涉及CA IX和XII以及其他尚未确定的靶标的一种以上的作用机理。
