communication reports the synthesis of decyl and hexadecyl hydroxytyrosyl ethers, as well as the cytotoxic activity of hydroxytyrosol and a series of seven hydroxytyrosol alkyl ether derivatives against A549 lung cancer cells and MRC5 non-malignant lung fibroblasts. Hydroxytyrosyl dodecyl ether (HTDE) showed the highest selective cytotoxicity, and possible mechanisms of action were investigated; results
最新数据表明,初榨橄榄油的酚类化合物羟基酪醇具有抗癌活性。该通报报道了癸基和十六烷基羟基酪醇醚的合成,以及羟基酪醇和一系列七个羟基酪醇烷基醚衍生物对A549肺癌细胞和MRC5非恶性肺成纤维细胞的细胞毒活性。羟基酪氨酰十二烷基醚(HTDE)显示出最高的选择性细胞毒性,并研究了可能的作用机理。结果表明,HTDE可以适度抑制糖酵解,诱导氧化应激并引起A549细胞DNA损伤。HTDE与抗癌药5-氟尿嘧啶的组合在A549癌细胞中诱导了协同的细胞毒性,但在非恶性MRC5细胞中却没有。HTDE还显示出相对于MCF10正常乳腺上皮细胞对MCF7乳腺癌细胞的选择性细胞毒性,其范围为1–30μM。这些结果表明,HTDE的细胞毒性比母体化合物羟基酪醇的细胞毒性更强且更具选择性。
