(IC50 = 3.6 nmol/L), good selectivity, excellent chemical stability and suitable metabolic stability. Further investigations showed that B11 acted as a competitive inhibitor of hNotum, while this agent (5 µmol/L) significantly weaken the migration abilities of colorectal cancer cells. Collectively, this study deciphers the SARs of chalcones as hNotum inhibitors and reports a novel and potent hNotum inhibitor
人类 Notum (hNotum) 抑制剂可用于治疗 Wnt 信号相关疾病,包括结直肠癌。在此,设计并合成了两个系列的查耳酮衍生物,旨在寻找选择性且有效的 hNotum 抑制剂。构效关系(SAR)研究表明,A环上的2-甲氧基和5-溴取代显着增强了抗hNotum作用,而B环上的4'-乙氧基和3'-烷基取代有利于hNotum抑制。在所有测试的查耳酮中,B11表现出最有效的抗Notum作用(IC 50 = 3.6 nmol/L)、良好的选择性、优异的化学稳定性和合适的代谢稳定性。进一步的研究表明,B11作为hNotum的竞争性抑制剂,而该剂(5 µmol/L)显着削弱结直肠癌细胞的迁移能力。总的来说,这项研究破译了查尔酮作为 hNotum 抑制剂的 SAR,并报告了一种新型有效的 hNotum 抑制剂,对结直肠癌细胞具有抗迁移作用,为开发新型抗癌药物提供了一种有前途的先导化合物。
