comparative tests using estrogen receptor positive and negative mammary tumor models. In cell culture, a growth inhibiting effect was only observed in hormone-sensitive MCF-7 cells, but not in hormone-independent MDA-MB 231 cells. In this assay, there was no significant difference between complexes and their ligands. In vivo, the growth of estrogen receptor positive MXT mouse mammary tumors was strongly inhibited
合成了许多[2-(氨基甲基)吡啶]二氯铂(II)配合物,它们通过不同长度的烷基间隔基团与5-羟基-2-(4-羟基苯基)吲哚连接,并研究了它们对小牛的结合亲和力子宫雌激素受体。它们的相对结合亲和力(RBA)值范围为1.0至5.2%(雌二醇,RBA = 100%)。发现具有在吡啶氨甲基和吲哚氮之间具有(CH 2)5或(CH 2)6桥的络合物具有最高的亲和力。在小鼠子宫重量测试中确定的复合物及其配体的内分泌活性较低。所有化合物均使用雌激素受体阳性和阴性乳腺肿瘤模型进行比较测试。在细胞培养中,仅在激素敏感性MCF-7细胞中观察到了生长抑制作用,但不适用于非激素依赖性MDA-MB 231细胞。在该测定中,复合物及其配体之间没有显着差异。在体内,复合物强烈抑制雌激素受体阳性MXT小鼠乳腺肿瘤的生长,而激素非依赖性MXT乳腺肿瘤仅表现出较小的反应。每周3 X 20 mg / kg的剂量,复合物10d-g
