The synthesis of two new highly potent 17beta-estradiol-linked platinum(II) complexes is described. The new molecules are linked at position 16 of the steroid nucleus with an alkyl chain. They are made from estrone in nine chemical steps with an overall yield exceeding 10%. The biological activity of these compounds was evaluated in vitro on estrogen dependent and independent (ER(+) and ER(-)) human
描述了两种新型的高效17β-雌二醇连接的铂(II)配合物的合成。新分子在类固醇核的位置16与烷基链连接。它们由雌酮经九个化学步骤制得,总收率超过10%。体外评估了这些化合物对雌激素依赖性和非依赖性(ER(+)和ER(-))人乳腺肿瘤细胞系MCF-7和MDA-MB-231的生物学活性。新化合物被证明对乳腺癌细胞系具有高度的细胞毒性。具有最高细胞毒性的衍生物对雌激素受体α具有高亲和力。
