(steroidal), and sugar moieties in their molecules has been synthesized and assayed as inhibitors of the zinc enzyme carbonic anhydrase (CA), and more precisely of the cytosolic isozymes CA I andII, and the transmembrane, tumor-associated isozymes CA IX. Some of these compounds were previously reported to act as inhibitors of steroid sulfatases, among which estrone sulfatase (ES) and dehydroepiandrosterone
已经合成了一系列在分子中结合了脂肪族,芳香族,多环(甾族)和糖基团的氨基磺酸盐或双氨基磺酸盐,并将其检测为锌酶碳酸酐酶(CA),更确切地说是胞质同工酶CA I的抑制剂。和II,以及跨膜,与肿瘤相关的同工酶CA IX。这些化合物中的某些以前据报道可充当甾族硫酸酯酶的抑制剂,其中雌酮硫酸酯酶(ES)和脱氢表雄甾酮硫酸酯酶(DHEAS)是雌激素依赖性肿瘤的关键治疗靶标。针对三种研究的CA同工酶,检测到非常有效的(纳摩尔量)抑制剂。最好的CA I抑制剂是苯氨基磺酸盐及其某些4-卤代衍生物,以及脂肪族化合物正辛基氨基磺酸盐。针对CA II,低纳摩尔抑制剂(1。1-5 nM)是苯氨基磺酸盐及其一些4-卤代/硝基衍生物,正辛基氨基磺酸盐和雌二醇3,17β-二氨基磺酸盐等。所有研究的氨基磺酸盐均显示出有效的CA IX抑制特性,抑制常数在18-63 nM的范围内。到目前为止,检测到的最好的CA IX抑制剂是
