As a novel class of IKKbeta inhibitors, a series of tricyclic furan derivatives was designed and synthesized based on the structure of known thiophene IKKbeta inhibitors. Among the various fused furan derivatives synthesized, a benzothieno[3,2-b]furan derivative 13a displayed potent inhibitory activity towards IKKbeta in enzymatic and cellular assays. The potent inhibitory activity originates from
作为一类新型的IKKbeta抑制剂,根据已知的噻吩IKKbeta抑制剂的结构设计和合成了一系列三环呋喃衍生物。在各种合成的融合呋喃衍生物中,苯并噻吩并[3,2-b]呋喃衍生物13a在酶和细胞分析中显示出对IKKbeta的有效抑制活性。有效的抑制活性源自分子内的非键合S ... O相互作用,这已通过JNK3的16k X射线结构得到证实。在核心结构上引入其他取代基导致发现了6-烷氧基衍生物,该衍生物具有与13a相当的IKKbeta抑制活性,并具有改善的代谢稳定性。其中,发现适当的亲脂性化合物16a,h,i和13g(log D> 2)具有良好的口服生物利用度。
