Harringtonolide (, ) is a bioactive diterpenoid tropone isolated from with antiproliferation activity. Until now there have been no reports to elucidate its anticancer mechanism. Herein we report the synthesis of -derived probes (, , and ) to identify the possible target of . As a result, the application of a novel photoaffinity alkyne-tagged probe from (compound ) showed direct engagement between and receptor for activated C kinase 1 (RACK1). Furthermore, could suppress the epithelial-mesenchymal transition (EMT) process and inhibit activation of the FAK/Src/STAT3 signaling pathway in A375 cells. This study provides a groundwork for as an effective antitumor agent that targets RACK1 to suppress cancer cell migration.
哈林顿醇内酯（，）是一种从[来源未提及]中分离得到的具有生物活性的二萜类环庚三烯酚酮，具有抗增殖活性。迄今为止，尚无报道阐明其抗癌机制。在此，我们报道了[未提及具体物质名称]衍生探针（，和）的合成，以确定[未提及具体物质名称]的可能靶点。结果，一种新型的来自[未提及具体物质名称]的光亲和炔烃标记探针（化合物）的应用表明，[未提及具体物质名称]与活化C激酶1受体（RACK1）之间存在直接相互作用。此外，[未提及具体物质名称]可抑制A375细胞中的上皮-间质转化（EMT）过程，并抑制FAK/Src/STAT3信号通路的激活。本研究为[未提及具体物质名称]作为一种靶向RACK1以抑制癌细胞迁移的有效抗肿瘤药物奠定了基础。
