Alkyne gold(I) derivatives with the water soluble phosphanes PTA (1,3,5-triaza-7-phosphaadamantane) and DAPTA (3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane) were described and their anticancer potential against the colon cancer cell line Caco-2 (PD7 and TC7 clones) was studied. Strong antiproliferative effects are found, for all the new complexes, to be even more pronounced than for the
炔金(我)描述了具有水溶性膦烷PTA(1,3,5-triaza-7-phosphaadamantane)和DAPTA(3,7-diacetyl-1,3,7-triaza-5-phosphabicyclocyclo [3.3.1] nonane)的衍生物并研究了它们对结肠癌细胞系Caco-2(PD7和TC7克隆)的抗癌潜力。对于所有新的复合物,发现强大的抗增殖作用比参考药物顺铂更为显着,并且与金诺芬相似。通过荧光光谱研究了这些衍生物与牛血清白蛋白(BSA)的相互作用。猝灭的类型和结合常数通过荧光猝灭法确定。对于测试的衍生物,计算出适中的结合常数值,表明这些复合物可以被该蛋白质轻易地存储和携带在体内。CCH 2 Spyridine)(PTA)]指出金属络合物与蛋白质之间存在范德华相互作用或氢键。另外,复合物[Au(C CCH 2吡啶)(PTA)]已显示出通过凋亡途径和细胞周期的S期阻滞抑制了H
