Abstract

Scale-up isolation of (+)-(5)-(8)-(14)-mycothiazole () from Vanuatu specimens of to semisynthesize (+)-(5)-(8)-8--acetyl-(14)-mycothiazole () revealed a new diastereomer, (-)-(5)-(8)-(14)-mycothiazole (). The structure of was determined using HRMS, NMR, and comparing optical rotation to (-)-(5)-(8)-(14)-mycothiazole () and . The maximum tolerated dose of in mice was 0.1 mg/kg. The IC of in PANC-1 and HepG2 cancer cell lines was 111.6 and 115.0 nM. Evaluation of in showed similar oxygen consumption compared to -, and all compounds significantly increased the lifespan. The orientation at Δ is crucial for picomolar cytotoxicity but not for mitochondrial inhibition.

摘要

从瓦努阿图标本中大规模分离(+)-(5)-(8)-(14)-mycothiazole (),以半合成(+)-(5)-(8)-8--acetyl-(14)-mycothiazole (),揭示了一种新的非对映异构体(-)-(5)-(8)-(14)-mycothiazole ()。通过高分辨率质谱、核磁共振和比较(-)-(5)-(8)-(14)-mycothiazole ()和 ()的比旋光度确定了的结构。在小鼠中的最大耐受剂量为 0.1 mg/kg。在 PANC-1 和 HepG2 癌细胞系中的 IC 为 111.6 和 115.0 nM。在 中的评估表明,与 -相比,氧消耗相似,所有化合物都显著延长了寿命。在 Δ处的 取向对于皮摩尔细胞毒性至关重要,但对于线粒体抑制不重要。
