classes of classical carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. A novel series of indolylchalcones incorporating benzenesulfonamide-1,2,3-triazole (6a-q) has been synthesized by click chemistry reaction and investigated for hCA inhibitory activity against a panel of human carbonic anhydrases (hCAs). Most of these newly synthesized compounds exhibited interesting inhibition constants, in the nanomolar
磺酰胺是最有前景的经典碳酸酐酶(CA,EC 4.2.1.1)抑制剂之一。通过点击化学反应合成了一系列新的吲哚基查耳酮并入苯磺酰胺-1,2,3-三唑(6a-q),并研究了其对人类碳酸酐酶(hCAs)的抑制作用。这些新合成的化合物大多数在纳摩尔范围内表现出令人感兴趣的抑制常数,其中一些衍生物对hCA I亚型的作用比标准药物乙酰唑胺(AAZ)强。在测试的化合物中,化合物6d(18.8 nM),6q(38.3 nM)和6e(50.4 nM)的效价分别比AAZ抗hCA I同工型高13、6和5倍。化合物6o,6m和6f有效抑制同工型hCA XII,KI的范围为10-41.9 nM。几种化合物还对同工型hCA II和hCA IX具有活性,KIs低于100 nM。这些吲哚基查耳酮-苯磺酰胺-1,2,3-三唑杂化物可能被认为是hCA I-选择性抑制剂的潜在先导。
