In this study, panaxadiol (PD) derivatives were designed and synthesized by the reaction of thiadiazoles with PD. The identity of all final products was elucidated by 1H, 13C NMR, HR-MS. The cytotoxicity activities of the derivatives were evaluated against four cancer cell lines using the MTT assay which revealed they indicated excellent anticancer activity. Among these compounds, SP24 had the most
在这项研究中,通过噻二唑与 PD 的反应设计和合成了人参二醇 (PD) 衍生物。1 H, 13阐明了所有最终产品的身份C NMR,HR-MS。使用 MTT 测定法评估了衍生物对四种癌细胞系的细胞毒性活性,结果表明它们具有优异的抗癌活性。在这些化合物中,SP24 具有最显着的细胞毒性,并明显抑制多种肿瘤细胞的生长。进一步研究表明,复方SP24可以降低A549中CDKs蛋白家族和Cyclin D1的表达水平,提示复方SP24可以阻断细胞周期。为了证明上述结论,我们通过分子对接的方法模拟了两种蛋白质的结合位点。结果表明SP24与两种cyclin的对接分数高于PD。基于目标蛋白和配体的复合物,我们推测增强的抗增殖活性可能与增加的氢键相互作用有关。因此,这些数据为化合物SP24有望成为治疗癌症的先导药物提供了参考。
