  Total synthesis of moniliformediquinone and calanquinone A as potent inhibitors for breast cancer

  摘要：

  The first synthesis of moniliformediquinone has been achieved in which the longest linear sequence is only nine steps. The synthesis proceeds in 23% overall yield from commercially available 2,4,5-trimethoxybenzaldehyde. The key transformations include a Pd-catalyzed coupling between a phenyl triflate and an acetylene, and a TiCl4-mediated cyclization of a benzoquinone intermediate. In addition, in vitro inhibitory effects of moniliformediquinone, denbinobin, moscatilin, and calanquinone A were determined to have IC50 values of 0.7, 1.6, 2.5, and 1.5 mu M, respectively.

  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。
