(iCSCL) model was recently established using induced pluripotent stem cells (iPSCs). In this study, a natural product-eucommicin A-was identified from Eucommia ulmoides leaves by screening for anti-CSC activity using the iCSCL model. Its structure was elucidated by spectroscopic methods as a quinic acid diester of 3,4,3',4'-tetrahydroxy-β-truxinic acid. Eucommicin A exhibited selective anti-CSC activity
癌症干细胞 (CSC) 构成肿瘤内的一小群未分化细胞,它们具有自我更新和驱动肿瘤形成的能力,因此表现为癌症起始癌细胞。消除 CSC 的治疗干预对于完全治愈患者是必要的,因为 CSC 是肿瘤复发和转移的重要来源。最近使用诱导多能干细胞 (iPSC) 建立了诱导 CSC 样 (iCSCL) 模型。在这项研究中,通过使用 iCSCL 模型筛选抗 CSC 活性,从杜仲叶中鉴定出一种天然产物杜仲素 A。其结构通过光谱方法阐明为 3,4,3',4'-四羟基-β-芦丁酸的奎尼酸二酯。Eucommicin A 表现出选择性抗 CSC 活性并抑制 iCSCL 细胞的肿瘤球形成。
