1-D and 2-D NMR spectroscopies, and by single-crystal X-ray analysis of [Pt(4-Mebpy)I2] (4). All the platinum(II) complexes (1–6) were evaluated for in vitro cytotoxicity against human cancer cell lines A2780 and A2780R, and against non-malignant MRC5 cell line. All the complexes were nontoxic up to the 50 μM concentration, although they were found to readily bind to calf-thymus DNA (CT-DNA), as determined
摘要
铂 (II) 配合物 [Pt(Lx)X2] (1–6),其中 X = Br 或 I 且 Lx =
2,2'-联吡啶或 1,10-
菲咯啉衍
生物(5,5'-二甲基-制备了
2,2'-联吡啶 (5-Mebpy)、
4,4'-二甲基-2,2'-联吡啶 (4-Mebpy) 和 5-
氨基-1,10-
菲咯啉 (5-NH2phen))。通过元素分析、质谱、红外和多核(1H、13C 和 195Pt)1-D 和 2-D NMR 光谱以及 [Pt(4-Mebpy) I2] (4). 评估了所有
铂 (II) 复合物 (1-6) 对人癌
细胞系 A2780 和 A2780R 以及非恶性 MRC5
细胞系的体外细胞毒性。尽管发现它们很容易与小牛胸腺 DNA (CT-DNA) 结合,但所有复合物在浓度高达 50 μM 时均无毒,
