Novel triphenylethylene-coumarin hybrid derivatives containing different amounts of amino side chains were designed and synthesized in good yields under microwave radiation. The derivatives 5b-d which possessed two amino side chains (except morpholinyl) showed a broad-spectrum and good anti-proliferative activity against five tumor cells and low cytotoxicity in osteoblast. UV-vis, fluorescence, and circular dichroism (CD) spectroscopies and thermal denaturation exhibited that compounds 10 c, 5c, and 13c bearing amino side chain (except morpholinyl) on 4-phenyl had significant interactions with Ct-DNA by the intercalative mode of binding. Structure-activity relationships (SARs) analysis suggested that the amino alkyl chain would play an important role both in the compounds against tumor cells proliferation and their interactions with DNA.
新型三苯乙烯-香豆素杂合衍生物含有不同数量的氨基侧链,在微波辐射下高产率地合成。具有两个氨基侧链(除吗啉基外)的衍生物 5b-d 对五种肿瘤细胞表现出广谱和良好的增殖抑制活性,且对成骨细胞的细胞毒性低。紫外可见光谱、荧光光谱和圆二色性(CD)光谱以及热变性表明,在 4-苯基上带有氨基侧链(除吗啉基外)的化合物 10c、5c 和 13c 与 CT-DNA 具有显著的相互作用,结合方式为插入式。构效关系(SAR)分析表明,氨基烷基链在化合物对肿瘤细胞增殖的抑制作用及其与 DNA 的相互作用中都起着重要的作用。
