hypoxia response in tumor cells. Therefore, its inhibitors have become one of the targets for the treatment of a variety of cancers. Two series of panaxadiol (PD) ester derivatives containing pyrazole () and pyrrole () moiety were synthesized and their HIF-1α inhibitory activities were evaluated. Among all the target compouds, compounds , , and (IC = 8.7010.44 μM) showed better HIF-1α inhibitory activity
缺氧诱导因子1α(HIF-1α)在多种肿瘤患者中过度表达,在调节肿瘤细胞缺氧反应中发挥重要作用。因此,其抑制剂已成为多种癌症的治疗靶点之一。合成了两个系列含有吡唑()和吡咯()结构的人参二醇(PD)酯衍生物,并评价了它们的HIF-1α抑制活性。在所有目标化合物中,化合物 、 和 (IC = 8.7010.44 μM) 显示出比 PD (IC = 13.35 μM) 更好的 HIF-1α 抑制活性。这些化合物均未表现出高于 100 μM 的细胞毒性,并以剂量依赖性方式抑制 HIF-1α 转录。这些化合物表现出良好的抗肿瘤活性,为PD酯衍生物的进一步设计和活性研究提供了先导化合物。
