series of topsentin analogs, in which the central imidazole ring of the natural lead was replaced by a 1,2,4‐oxadiazole moiety, was efficiently synthesized. All derivatives were pre‐screened for antiproliferative activity against the National Cancer Institute (NCI‐60) cell lines panel. The five most potent compounds were further investigated in various pancreatic ductal adenocarcinoma (PDAC) cell lines
高效合成了一系列新的topsentin类似物,其中天然铅的中心咪唑环被1,2,4-恶二唑部分取代。所有衍生物均针对美国国家癌症研究所 (NCI-60) 细胞系面板的抗增殖活性进行了预筛选。在各种胰腺导管腺癌 (PDAC) 细胞系中进一步研究了五种最有效的化合物,包括 SUIT-2、Capan-1 和 Panc-1 细胞,引发 EC 50微摩尔和亚微摩尔范围内的值,与细胞迁移的显着减少有关。这些显着的结果可能是由于这些新的 topsentin 类似物对上皮-间质转化标志物的影响,包括 SNAIL-1/2 和金属蛋白酶-9。此外,Annexin V-FITC 和碘化丙啶染色后的流式细胞术分析表明,这些衍生物增强了 PDAC 细胞的凋亡。与这些数据保持一致,PathScan 细胞内信号传导和 ELISA 阵列显示 caspase-3 和 PARP 的裂解以及 GSK3β 磷酸化的显着抑制,表明该
