An efficient synthesis of the Alpinia officinarum-derived diarylheptanoids, viz., enantiomers of a β-hydroxyketone (1) and an α,β-unsaturated ketone (2) was developed starting from commercially available eugenol. Among these, compound 2 showed a superior antiproliferative effect against human breast adenocarcinoma MCF-7 cells. Besides reducing clonogenic cell survival, compound 2 dose-dependently increased
从市售丁香酚开始,开发了一种有效合成山姜衍生的二芳基庚烷类化合物,即 β-羟基酮 ( 1 ) 和 α,β-不饱和酮 ( 2 ) 的对映异构体。其中,化合物2对人乳腺癌MCF-7细胞显示出优异的抗增殖作用。正如流式细胞术所揭示的那样,除了降低克隆形成细胞的存活率外,化合物2剂量依赖性地增加了亚 G1 细胞群并阻止了细胞周期的 G2 期。从机制上讲,化合物2通过产生大量活性氧而起到细胞内促氧化剂的作用。化合物2还诱导 MCF-7 细胞中线粒体膜电位 (MMP) 和溶酶体膜透化 (LMP) 的丧失。由于化合物2产生活性氧 (ROS) 导致的线粒体和溶酶体功能受损可能有助于其凋亡特性。
