resorcinol derivatives and suitable β-ketoesters. The evaluation of inhibitory activity revealed that these compounds possessed nanomolar affinity and high selectivity towards tumour-associated hCA IX and XII over cytosolic hCA I and hCA II isoforms. To investigate the binding mode of these new coumarin-inspired inhibitors, the most active compounds 10 and 17 were docked within hCA XII catalytic cleft.
摘要 香豆素是广泛散布的次级代谢产物,具有多种生物学活性。已经确定,香豆素代表一类特殊的人类碳酸酐酶(hCA)抑制剂,具有独特的作用机制,涉及与非经典结合的氨基酸残基铺平了hCA催化位点的入口。在这里,我们报告的小编新的香豆素衍生物的合成7-11,15,17由间苯二酚衍生物和合适的β-酮酸酯通过经典的Pechmann缩合制备。抑制活性的评估表明,这些化合物相对于胞质hCA I和hCA II同种型具有纳摩尔摩尔亲和力和对肿瘤相关hCA IX和XII的高选择性。为了研究这些新的香豆素类抑制剂的结合方式,将活性最高的化合物10和17停靠在hCA XII催化裂隙内。
