1) inhibitory activity of the new compounds was assessed against four human (h) isoforms, hCA I, hCA II, hCA IV and hCA XII. Among them, hCA II, IV and XII are antiglaucoma drug targets, being involved in aqueous humor secretion within the eye. Low nanomolar inhibition was measured against all four isoforms with the 20 reported sulfonamides, but no selective inhibitory profiles, except for some CA
使N-保护的氨基酸(Gly,Ala和Phe被Boc和Z基团保护)与磺酰胺衍生物反应,得到相应的N-保护的氨基酸-磺酰胺缀合物。评估了新化合物的碳酸酐酶(CA,EC 4.2.1.1)对四种人(h)异构体hCA I,hCA II,hCA IV和hCA XII的抑制活性。其中,hCA II,IV和XII是抗青光眼药物的靶标,参与眼内房水的分泌。使用20种已报告的磺酰胺类药物,对所有四种同工型均测得较低的纳摩尔抑制率,但未观察到选择性抑制谱,除了一些CA XII选择性衍生物。hCA I,II和XII通常被掺入更长支架和Gly / Ala的磺酰胺更好地抑制,而最好的hCA IV抑制剂是高磺胺衍生物,并入苯丙氨酸部分。氨基酸-磺酰胺结合物显示出良好的水溶性和有效的hCA II,IV和XII抑制作用,可以被认为是抗青光眼研究的有趣候选物。
