Calanquinone A (1) was isolated from an EtOAc-soluble extract of Calanthe arisanensis through bioassay-guided fractionation. Its structure was identified by spectroscopic methods. Compound 1 showed potent cytotoxicity (EC(50)<0.5microg/mL) against lung (A549), prostate (PC-3 and DU145), colon (HCT-8), breast (MCF7), nasopharyngeal (KB), and vincristine-resistant nasopharyngeal (KB-VIN) cancer cell
Calanquinone A (1) 是通过生物测定引导的分级分离从 Calanthe arisanensis 的 EtOAc 可溶性提取物中分离出来的。其结构通过光谱方法鉴定。化合物 1 对肺 (A549)、前列腺 (PC-3 和 DU145)、结肠 (HCT-8)、乳腺 (MCF7)、鼻咽 (KB) 和长春新碱显示出有效的细胞毒性 (EC(50)<0.5microg/mL)抗性鼻咽 (KB-VIN) 癌细胞系,有趣的是,与紫杉醇相比,耐药性有所改善。还实现了 1 的全合成并在本文中进行了报道。
