D24 melanoma cells and showed significant anticancer activity in 3D spheroidal models of melanoma cells. Mechanistic investigations of 3c activity indicate thioredoxin reductase inhibition through steric and hydrogen-bonding interactions, followed by the induction of oxidative stress and a mitochondrial pathway of cell death. Compound 3c also showed significant antiangiogenic properties in a transgenic
合成并表征了一系列含有甲氧基取代的肉桂酰胺部分(3a - 3c和4a - 4c)的炔基金(I)膦配合物。评估了所有合成的复合物对三种人类癌细胞系A549(肺),D24(黑素瘤)和HT1080(纤维肉瘤)以及人类胚胎肾293细胞系(Hek293T)的细胞毒性,作为非癌细胞的代理模型。大多数合成的化合物在低微摩尔浓度下对癌细胞系均具有抗增殖活性。其中,复合物3c对IC 50表现出广泛的抗癌活性对于所有测试的癌症品系,其值在1.53–6.05μM的范围内。复合物3c对D24黑色素瘤细胞的毒性比参考药物顺铂高20倍,并且在黑色素瘤细胞的3D球形模型中显示出显着的抗癌活性。对3c活性的机理研究表明,硫氧还蛋白还原酶通过空间和氢键相互作用抑制,随后诱导氧化应激和细胞死亡的线粒体途径。在转基因斑马鱼Tg(fli1a:EGFP)体内模型中,化合物3c还显示出显着的抗血管生成特性。
