A series of sixteen novel aromatic and heterocyclic bis-sulfonamide Schiff bases were prepared by conjugation of well known aromatic and heterocyclic aminosulfonamide carbonic anhydrase (CA, EC 4.2.1.1) inhibitor pharmacophores with aromatic and heterocyclic bis-aldehydes. The obtained bis-sulfonamide Schiff bases were investigated as inhibitors of four selected human (h) CA isoforms, hCA I, hCA II

A novel series of sulfonamide-incorporated bis(α-aminophosphonates) acting as effective carbonic anhydrase (CA, EC 4.2.1.1) inhibitors is reported. The synthesized bivalent ligands were tested against five human (h) isoforms, hCA I, hCA II, hCA VII, hCA IX, and hCA XIII. Such derivatives showed high activity and selectivity against the cancer-related, membrane-bound isoform hCA IX, and among them,
据报道,一系列新型磺酰胺掺入的双(α-氨基膦酸盐)可作为有效的碳酸酐酶(CA,EC 4.2.1.1)抑制剂。合成的二价配体针对五种人类 (h) 同种型:hCA I、hCA II、hCA VII、hCA IX 和 hCA XIII 进行测试。这些衍生物对癌症相关的膜结合亚型hCA IX表现出高活性和选择性,其中化合物5h ,四异丙基(1,3-亚苯基双[(4-氨磺酰基苯基)氨基]亚甲基})双(膦酸酯)显示K I为 15.1 nM,与所有其他研究的亚型相比,对该亚型具有高度选择性(hCA I/IX = 42;hCA II/IX = 6,hCA VII/IX = 3,hCA XIII/IX = 5)。因此,化合物5h可能成为开发选择性抗癌药物的潜在先导。新开发的磺胺类药物还被发现能有效抑制胞质 hCA XIII 亚型。化合物5i对这种亚型表现出最佳抑制作用, K I为 17.2 nM,与众所周知的抑制剂乙酰唑胺
