A series of 1,2,3-triazole-linked triazino[5,6-b]indole-benzene sulfonamide hybrids (6a-6o) was synthesized and evaluated for carbonic anhydrase (CA, EC 4.2.1.1) inhibitory activity against the human (h) isoforms hCA I, II, XIII (cytosolic isoforms), and hCA IX (transmembrane tumor-associated isoform). The results revealed that the compounds 6a-6o exhibited Ki values in the low to medium nanomolar
合成了一系列1,2,3-三唑连接的三嗪并[5,6-b]吲哚-苯磺酰胺杂化物(6a-6o),并评估了碳酸酐酶(CA,EC 4.2.1.1)对人体的抑制活性(h)同工型hCA I,II,XIII(胞质同工型)和hCA IX(跨膜肿瘤相关同工型)。结果表明,化合物6a-6o相对于hCA II和hCA IX在低至中等纳摩尔范围内显示Ki值(Kis在7.7 nM至41.3 nM之间),对hCA I和hCA XIII的Ki值较高。与标准抑制剂乙酰唑胺(AAZ)(Ki = 12.1 nM)相比,化合物6i显示出对hCA II的有效抑制作用(Ki = 7.7nM)。化合物6b和6d显示出对hCA XIII的中等活性(Ki = 69.8和65.8nM)。因此,
