In this study, we introduced 1, 2, 4-triazole groups into panaxadiol (PD) to obtain 18 panaxadiol triazole derivatives. Five cancer cells and one normal cell were evaluated for cytotoxicity by MTT assay. The results showed that most of the derivatives could inhibit cancer cell proliferation, and the anti-proliferative activity of compound A1 was the most significant. For HepG-2 cells, the IC₅₀ value was 4.21 ± 0.54 μM, which was nearly 15 times higher than the activity of PD. Further studies showed that compound A1 could induce apoptosis in HepG-2 cells, and could enhance the expression of Cl-caspase-3, Cl-caspase-9 and Cl-PARP. Moreover, Western blot analysis showed that after treating HepG-2 cells with compound A1, the expression of p53 protein was increased and the ratio of Bax/Bcl-2 was gradually increased. The cytoplasmic Bax is then translocated to the mitochondria, causing the release of Cyt c protein. Therefore, the results indicate that compound A1 induces apoptosis through the mitochondrial pathway and can be used the potential to develop new anti-proliferative agents.

在这项研究中，我们将1，2，4-三唑基引入人参二醇（PD）中，以获得18种人参二醇三唑衍生物。通过MTT测定评估了5个癌细胞和1个正常细胞的细胞毒性。结果表明，大多数衍生物均可抑制癌细胞的增殖，化合物A1的抗增殖活性最为显着。对于HepG-2细胞，IC ₅₀值为4.21±0.54μM，几乎是PD活性的15倍。进一步的研究表明，化合物A1可以诱导HepG-2细胞凋亡，并可以增强Cl-caspase-3，Cl-caspase-9和Cl-PARP的表达。此外，蛋白质印迹分析表明，用化合物A1处理HepG-2细胞后，p53蛋白的表达增加，Bax / Bcl-2的比例逐渐增加。然后将细胞质的Bax转运到线粒体，导致Cyt c蛋白释放。因此，结果表明化合物A1通过线粒体途径诱导细胞凋亡，可用于开发新的抗增殖剂。
