Our team discovered a moderate SphK1 inhibitor, SAMS10 (IC50 = 9.8 μM), which was screened by computer-assisted screening. In this study, we developed a series of novel diaryl derivatives with improved antiproliferative activities by modifying the structure of the lead compound SAMS10. A total of 50 new compounds were synthesized. Among these compounds, the most potent compound, named CHJ04022Rb, has
我们的团队通过计算机辅助筛选发现了一种中度 SphK1 抑制剂SAMS10 (IC 50 = 9.8 μM)。在这项研究中,我们通过改变先导化合物SAMS10的结构,开发了一系列具有改善抗增殖活性的新型二芳基衍生物。共合成了 50 种新化合物。在这些化合物中,最有效的化合物CHJ04022Rb在黑色素瘤 A375 细胞系中具有显着的抗癌活性 (IC 50 = 2.95 μM)。进一步的潜在机制研究表明,CHJ04022R对 PI3K/NF-κB 信号通路具有抑制作用,通过诱导 A375 细胞 G2/M 期阻滞,抑制 A375 细胞的迁移,促进细胞凋亡并发挥抗增殖作用。此外,急性毒性实验表明CHJ04022R在体内表现出良好的安全性。此外,它对裸鼠异种移植瘤的生长表现出剂量依赖性抑制作用。因此,CHJ04022R可能是治疗黑色素瘤的潜在候选药物。
