Triple-negative breast cancer (TNBC), representing the most aggressive form of breast cancer with currently no targeted therapy available, is characterized by an inflammatory and hypoxic tumor microenvironment. To date, a broad spectrum of anti-tumor activities has been reported for phenanthroindolizidine alkaloids (PAs), however, their mode of action in TNBC remains elusive. Thus, we investigated
三阴性乳腺癌 (TNBC) 是目前尚无靶向治疗的最具侵袭性的乳腺癌形式,其特征是炎症和缺氧的肿瘤微环境。迄今为止,已经报道了菲咯吲哚里西啶生物碱 (PAs) 具有广谱的抗肿瘤活性,然而,它们在 TNBC 中的作用方式仍然难以捉摸。因此,我们研究了从植物Tylophora ovata中提取的六种天然 PA :O-甲基tylophorinidine ( 1 ) 及其五种衍生物tylophorinidine ( 2 )、tylophoridicine E ( 3 )、2-demethoxytylophorine ( 4 )、tylophoridicine D ( 5 ) 和无水脱氢甲酚定(6)。与天然 ( 1 ) 相比,为了进行更深入的研究,我们还使用了合成的O-甲基 tylophorinidine ( 1s ) 样品。我们的结果表明化合物 ( 1 ) 和 ( 1s ) (IC 50 = 17.1
