activity on human breast cancer cell line MCF-7. Human (h) CA isoforms I, II and IX were included in the study. The new sulfonamides showed excellent inhibition of all three isoforms, with KIs in the range of 0.84–702 nM against hCA I, of 0.41–288 nM against hCA II and of 5.6–29.2 against the tumor-associated hCA IX, a validated anti-tumor target, with a sulfonamide (SLC-0111) in Phase I clinical trials
合成了一系列的4-(噻唑-2-基氨基)-苯磺酰胺,并筛选了它们的碳酸酐酶(CA,EC 4.2.1.1)对人乳腺癌细胞系MCF-7的抑制和细胞毒活性。研究中包括人(h)CA同工型I,II和IX。新的磺酰胺类药物对所有三种同工型均表现出优异的抑制作用,对hCA I的K I范围为0.84–702 nM,对hCA II的K I范围为0.41–288 nM,对与肿瘤相关的hCA IX的K I范围为5.6–29.2。在I期临床试验中使用磺酰胺(SLC-0111)作为抗肿瘤靶标,用于治疗过表达CA IX的低氧,转移性实体瘤。新化合物显示出微摩尔抑制对乳腺癌MCF-7细胞系生长功效的抑制作用。
