Dithiocarbamates (DTCs) were recently discovered as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. A series of xanthates and a trithiocarbonate, structurally related to the DTCs, were prepared by reaction of alcohols/thiols with carbon disulfide in the presence of bases. These compounds were tested for the inhibition of four human (h) isoforms, hCA I, II, IX, and XII, involved in pathologies such
最近发现二硫代氨基甲酸酯(DTC)作为碳酸酐酶(CA,EC 4.2.1.1)抑制剂。在碱的存在下,通过醇/硫醇与二硫化碳的反应制备了一系列与DTC相关的黄原酸酯和三硫代碳酸酯。测试了这些化合物对四种人类(h)亚型hCA I,II,IX和XII的抑制作用,它们参与了诸如青光眼(CA II和XII)或癌症(CA IX)等病理过程。检测到了几种针对这些CA的低纳摩尔黄原酸酯/三硫代碳酸酯抑制剂。对CA II活性位点中的一些黄药的对接研究表明,这些化合物与二硫代氨基甲酸酯以类似的方式结合,单齿配位于酶活性位点的Zn(II)离子。通过局部给药,在两种青光眼动物模型中,几种黄药显示出有效的降低眼内压的活性。黄药和硫代黄药代表了两种新颖的,有前途的CA抑制剂。
