respectively. Compound 4 possessed 14-fold greater aqueous solubility than 1 and increased ROS levels in colorectal cancer HCT-116 cells. Additionally, 4 preferably inhibited proliferation, migration, invasion, and heteroadhesion of HCT-116 cells. Treatment with 4 suppressed tumor growth and lung metastasis in vivo and prolonged the survival of tumor-bearing mice. Furthermore, 4 mitigated TGF-β1-induced epithelial-mesenchymal
Piperlongumine 1可增加活性氧(ROS)的水平,并优选通过触发不同的途径诱导癌细胞凋亡。但是,1的较差的溶解度限制了其深入的研究和临床应用。川gust嗪具有水溶性吡嗪骨架,可以抑制癌细胞的增殖和转移。我们通过用川gust嗪部分取代1的三甲氧基苯基来合成化合物3,并进一步将2-Cl,-Br和-I引入3分别合成4-6。化合物4在结肠直肠癌HCT-116细胞中的水溶性比1高14倍,并且ROS水平升高。另外,优选4种抑制HCT-116细胞的增殖,迁移,侵袭和异粘附。用4处理可抑制体内肿瘤的生长和肺转移,并延长荷瘤小鼠的生存期。此外,4通过抑制HCT-116细胞中的Akt和GSK-3β磷酸化,减轻了TGF-β1诱导的上皮-间质转化和Wnt /β-catenin活化。总的来说,有4个显示出显着的抗增殖和抗转移活性,优于1。
