isozymes I, II, and IV of carbonic anhydrase (CA). Metal complexes of the new compounds have also been prepared. Metal ions used in such preparations included di- and trivalent main-group and transition cations, such as Zn(II), Cu(II), Al(III), etc. Some of the new sulfonamides/disulfonamides obtained in this way, as well as their metal complexes, behaved as nanomolar CA inhibitors against isozymes II and
聚氨基-多羧酸或其二酐与具有游离氨基/亚氨基/肼基/羟基的芳族/杂环磺酰胺的反应提供了在其分子中包含聚氨基-多羧酸部分的单和双磺酰胺。合成中使用的酸/酐包括IDA,NTA,EDDA,EDTA和EDTA二酐,DTPA和DTPA二酐,EGTA和EGTA二酐,以及EDDHA。所有新制备的衍生物均对碳酸酐酶(CA)的同工酶I,II和IV具有很强的亲和力。还制备了新化合物的金属配合物。此类制备中使用的金属离子包括二价和三价主基团和过渡阳离子,例如Zn(II),Cu(II),Al(III)等。以此方式获得的一些新的磺酰胺/二磺酰胺,例如以及他们的金属配合物 表现为抗同工酶II和IV的纳摩尔CA抑制剂,对同工酶I的抑制作用稍差。当局部将这些磺酰胺及其金属配合物直接施用于正常血压/青光眼兔眼中时,它们会大大降低眼内压(IOP) 1-2%的水溶液/悬浮液。这些磺酰胺CA抑制剂的良好水溶性与眼科应用中所用水溶
