antitumor phase II drug SLC-0111 are described, namely ureido-substituted benzenesulfonamides appended with a nitro-aromatic moiety to yield an antiproliferative action increased by hypoxia. These compounds were screened for the inhibition of the ubiquitous hCA I/II and the target hCA IX/XII. Six X-ray crystallographies with CA II and IX/mimic allowed for the rationalization of the compounds inhibitory
人类碳酸酐酶(CA,EC,4.2.1.1)IX和XII在癌细胞中过度表达,是对许多肿瘤所特有的对缺氧和酸性条件的适应性反应。另外,低氧促进了特定的氧化还原酶的活性,该特定的氧化还原酶可用于选择性激活生物还原性前药。在此,描述了新的选择性CA IX / XII抑制剂,作为抗肿瘤II期药物SLC-0111的类似物,即脲基取代的苯磺酰胺类化合物,其上附加有硝基芳香族基团以产生因缺氧而增加的抗增殖作用。筛选了这些化合物对普遍存在的hCA I / II和目标hCA IX / XII的抑制作用。六个具有CA II和IX / mimic的X射线晶体学使化合物的抑制活性合理化。某些此类化合物对HT-29的活力的影响,
