anhydrase (CA, EC 4.2.1.1) inhibitor in Phase I clinical trials. The new derivatives incorporated ureido moieties as spacers between the benzene sulfamate fragment which binds the zinc ion from the active site, and the tail of the inhibitor, but the urea moieties were part of a substituted piperazine ring system. The derivatives (and some of their phenol precursors) were tested for the inhibition of the cytosolic
在I期临床试验中,使用磺酰胺碳酸酐酶(CA,EC 4.2.1.1)抑制剂作为先导化合物SLC-0111合成了一系列氨基磺酸盐。新的衍生物在结合氨基磺酸根的苯磺酸盐片段和抑制剂的尾部之间引入了脲基部分作为间隔物,后者与活性位点的锌离子结合,但是脲部分是取代的哌嗪环系统的一部分。测试了衍生物(及其一些酚前体)对胞质,hCA I和II(脱靶同工型)和跨膜,与肿瘤相关的hCA IX和XII酶(抗癌靶标)的抑制作用。通常,hCA I不能被有效抑制,而许多低纳摩尔抑制剂被证明可抵抗hCA II(K I在1.0–94.4 nM范围内),IX(K我S IN 0.91-36.9纳米范围内),和XII(ķ我S IN 1.0-84.5以下的范围内)。哌嗪环上的最佳取代片段包括以下部分:3-甲基苯基,2,3-二甲基苯基,4-甲氧基苯基,6-芳基嘧啶-2-基。
