isoforms hCA I, II, IV and IX, using a stopped-flow CO2 hydrase assay. All these isoforms were inhibited by the enaminones reported here in variable degrees. The target tumor-associated isoform hCA IX was undeniably the most affected one (KIs: 0.21–7.1 nM), with 6- to 21-fold enhanced activity than SLC-0111 (KI = 45 nM). All the prepared enaminones displayed interesting selectivity towards hCA IX over
SLC-0111是脲基取代的苯磺酰胺,是一种选择性碳酸酐酶(CA,EC 4.2.1.1)IX抑制剂,目前正在I / II期临床试验中,用于治疗晚期低氧肿瘤并发转移。在这里,我们报告了两个系列的3 / 4-(3-芳基-3-氧代丙烯基)氨基苯磺酰胺5a–i和6a–j的合成,它们是SLC-0111烯胺酮同类物。使用停止流动的CO 2在体外研究了制备的烯胺酮作为金属酶碳酸酐酶(CA,EC 4.2.1.1)异构体hCA I,II,IV和IX的抑制剂水合酶测定。所有这些同工型均受到本文报道的烯胺酮的不同程度抑制。不可否认,与靶标肿瘤相关的同工型hCA IX是受影响最严重的同种型(K I s:0.21–7.1 nM),其活性比SLC-0111(K I = 45 nM)提高了6到21倍。所有制备的烯胺酮对hCA IX的选择性都比hCA I(SI:32 –> 35714),hCA II(SI:2 – 1689)和hCA
