A series of sulfonamides has been obtained by reaction of 4-isothiocyanatobenzenesulfonamide with amines, amino acids, and oligopeptides. The new thiourea derivatives showed strong affinities toward isozymes I, II, and IV of carbonic anhydrase (CA, EC 4.2.1.1). In vitro inhibitory power was good (in the low-nanomolar range) for the derivatives of beta-phenylserine and alpha-phenylglycine, for those
通过4-异硫氰酸根合苯磺酰胺与胺,氨基酸和寡肽的反应获得了一系列磺酰胺。新的硫脲衍生物对碳酸酐酶的同功酶I,II和IV具有很强的亲和力(CA,EC 4.2.1.1)。对于β-苯基丝氨酸和α-苯基甘氨酸的衍生物,掺入羟基和巯基氨基酸(Ser,Thr,Cys,Met),疏水性氨基酸(Val, Leu,Ile),芳香族氨基酸(Phe,His,Trp,Tyr,DOPA)和二羧酸氨基酸,以及二/三/四肽等。这种CA抑制剂主要以(羧酸盐)钠盐形式显示出非常好的水溶性(在2-3%范围内),所得溶液的pH值为6.5-7.0。这些制剂中的某些(例如Ser,β-Ph-Ser,Leu,Asn等的衍生物)以2%的水溶液直接局部施用到降压/青光眼兔眼中时,可大大降低眼压(IOP) 。有趣的是,并非本研究中设计的所有功能强大的CA抑制剂都显示出局部IOP降低作用(例如,Cys和Lys衍生物,缺乏这种特性),而Pro,
