development of new anticancer agents. In this study, a series of sulfonamide derivatives were designed and synthesized as potential CA IX inhibitors from a lead compound (benzoyl thioureido benzene sulfonamide) discovered by virtual screening. The bioassay demonstrated that some of the synthesized compounds exhibited potent inhibitory activity against CA IX in the subnanomolar range and high selectivity over
CA IX 作为开发新型抗癌药物的有前景的靶点而备受关注。在本研究中,通过虚拟筛选发现的先导化合物(苯甲酰基
硫脲基苯磺酰胺)设计并合成了一系列磺酰胺衍
生物作为潜在的 CA IX
抑制剂。
生物测定表明,一些合成的化合物对亚纳摩尔范围内的 CA IX 表现出有效的抑制活性,并且对同工酶 CA I 和 CA II 具有高选择性。其中,化合物6a对CA IX表现出抑制活性,IC 50值为0.48 nM,选择性是CA II的约1500倍。还通过分子对接分析了新磺酰胺衍
生物的构效关系和CA IX选择性。
