cytosolic hCA I and II, and the transmembrane, tumor-associated hCA IX. The new compounds reported here inhibited hCA I with K(I)s in the range of 75-136nM, hCA II with K(I)s in the range of 13-278nM, and hCA IX with K(I)s in the range of 0.12-549nM. The first hCA IX-selective inhibitors were thus detected, as the chlorotriazinyl-sulfanilamide and the bis-ethoxytriazinyl derivatives of sulfanilamide/homosulfanilamide
通过氰尿酰氯与磺酰胺,高磺酰胺或4-氨基乙基苯磺酰胺的反应,获得了一系列在分子中结合有三嗪部分的苯磺酰胺衍生物。随后通过与各种亲核试剂,例如水,甲胺或脂肪醇(甲醇和乙醇)反应,将二氯三嗪基-苯磺酰胺中间体衍生化。测试了包含三嗪基部分的磺酰胺文库对三种生理相关的碳酸酐酶(CA,EC 4.2.1.1)同工酶,胞质hCA I和II以及跨膜,与肿瘤相关的hCA IX的抑制作用。此处报道的新化合物在75-136nM范围内抑制了hCA I,K(I)s在13-278nM范围内抑制了hCA II,在K-Iss的范围内抑制了hCA IX。 0.12-549nM。从而检测到第一个hCA IX选择性抑制剂,因为磺胺/高磺基磺酰胺的氯三嗪基-磺胺基酰胺和双乙氧基三嗪基衍生物在166-706范围内显示出对CA IX的选择性比对CA II的选择性。此外,这些化合物中的一些对hCA IX具有亚纳摩尔亲和力,K(I)在0
