Fluorescence properties of some of the representative molecules obtained in this way were studied. The synthesised 2-(1,3,4-oxadiazolo-2-yl)aniline-benzene sulphonamides (8a-o) were screened for their carbonic anhydrase (CA, EC 4.2.1.1) inhibitory activity. Most of the compounds exhibited low micromolar to nanomolar activity against human (h) isoforms hCA I, hCA II, hCA IV, and XII, with some compounds displaying
在分子碘的存在下,采用靛红和酰肼为起始原料,开发了一种实用的,无过渡金属的一锅多米诺骨牌合成的多样化(1,3,4-恶二唑-2-基)苯胺。这种多米诺骨牌工艺的显着特征是在一锅法中连续缩合,水解环裂解和分子内脱羧,从而导致CO键的氧化形成。研究了以此方式获得的一些代表性分子的荧光性质。筛选合成的2-(1,3,4-恶二唑-2-基)苯胺-苯磺酰胺(8a-o)的碳酸酐酶(CA,EC 4.2.1.1)抑制活性。大多数化合物对人(h)亚型hCA I,hCA II,hCA IV和XII的微摩尔/纳摩尔活性较低,
