reacting 4-isothiocyanato- or 4-isothiocyanatoethyl-benzenesulfonamide with amines, hydrazines, or amino acids bearing moieties that can lead to an enhanced hydrosolubility, such as 2-dimethylamino-ethylamine, fluorine-containing aromatic amines/hydrazines, an aminodiol, heterocyclic polyamines (derivatives of morpholine and piperazine), 4-aminobenzoic acid, or natural amino acids (Gly, Cys, Asn, Arg, and
通过使4-异硫氰酸根合或4-异硫氰酸根合乙基-苯磺酰胺与胺,肼或带有可导致增强的水溶性的部分的氨基酸(例如2-二甲基氨基-乙胺,氟-含有芳族胺/肼,氨基二醇,杂环多胺(吗啉和哌嗪的衍生物),4-氨基苯甲酸或天然氨基酸(Gly,Cys,Asn,Arg和Phe)。新化合物显示出对三种生理相关的碳酸酐酶(CA,EC 4.2.1.1)同工酶的良好抑制特性,其中K(I)对胞质同工型CA I的范围为24-324 nM,对K-I的范围为6-185 nM。其他的胞质同工酶CA II,以及针对跨膜同工酶XIA的1.5-144 nM。作为青光眼动物模型,一些新的衍生物在降低高血压兔眼内压升高方面也非常有效。考虑到这是首次在体内设计和研究有效的CA II / CA XII抑制剂的研究,因此可以假定抗青光眼磺酰胺的目标同工酶确实是胞质CA II和跨膜CA XII。
