Previously we have reported a series of gambogic acid's analogs and have identified a compound that possessed comparable in vitro growth inhibitory effect as gambogic acid. However, their target protein as well as the key pharmacophoric motifs on the target have not been identified yet. Herein we report that gambogic acid and its analogs inhibit the activity of IκB Kinase-beta (IKKβ) through suppressing
以前,我们已经报道了一系列藤黄酸的类似物,并鉴定出了一种具有与藤黄酸相当的体外生长抑制作用的化合物。但是,尚未鉴定其靶蛋白以及靶上的关键药效基序。在本文中,我们报道藤黄酸及其类似物通过抑制TNFα/NF-κB途径的激活而抑制了IκB激酶-β(IKKβ)的活性,这反过来又诱导了A549和U251细胞凋亡。IKKβ可以作为藤黄酸的靶标之一。文章中仔细讨论了化合物的制备。笼中的4-氧杂-三环[4.3.1.0 3,7被认为是药效学支架的] dec-2-one蒽酮代表了一种有前途的癌症治疗剂和有用的针对NF-κB途径的探针。
