important role in tumor progression. Specific CA IX inhibitors potentially could serve as anti-cancer drugs. We designed a series of sulfonamide inhibitors containing carborane clusters based on prior structural knowledge of carborane binding into the enzyme active site. Two types of carborane clusters, 12-vertex dicarba-closo-dodecaborane and 11-vertex 7,8-dicarba-nido-undecaborate (dicarbollide), were connected
碳酸酐酶IX(CA IX)是在缺氧肿瘤中过表达的跨膜酶,在缺氧肿瘤中起重要作用。特定的CA IX抑制剂可能会用作抗癌药。基于碳硼烷结合到酶活性位点的现有结构知识,我们设计了一系列含有碳硼烷簇的磺酰胺抑制剂。两种类型的碳硼烷簇的,12顶点dicarba-闭合碳-dodecaborane和11顶点-7,8- dicarba-巢-undecaborate(dicarbollide),被连接到一个磺酰胺部分通过不同长度(1-4个碳原子脂族连接基; n = 1-4)。体外CA的测试抑制能力表明,对于CA IX的选择性抑制的最佳的接头长度为n = 3,A 1-sulfamidopropyl -1,2- dicarba-闭合碳-dodecaborane(3)成为最强CA IX抑制剂从这个系列中, K i值为0.5 nM,对CA IX的选择性是CA II的大约1230倍。X射线研究3在CA IX活动位点的
