derivatives is described, which are inhibitors of carbonic anhydrase (CA). The most potent of these is the racemic fluoro sulfone 9, which inhibits carbon dioxide hydration catalyzed by human CA II (CA-II) with an IC50 of 3 nM. Binding competition studies versus dansylamide indicate that the enantiomers of 9 have different affinities for CA-II, with equilibrium dissociation constants of 3.6 and 0.6 nM. QSAR
描述了一系列的磺酰基甲磺酰胺衍生物,它们是碳酸酐酶(CA)的抑制剂。其中最有效的是外消旋氟砜9,它可抑制人CA II(CA-II)催化的二氧化碳水合,IC50为3 nM。与丹磺酰胺的结合竞争研究表明,9的对映异构体对CA-II具有不同的亲和力,平衡解离常数为3.6和0.6 nM。QSAR分析表明,在该系列中实现高亲和力的关键因素是磺酰胺酸度,疏水性和与磺酰胺基团相邻的碳原子处的空间需求最小化。
