The cytotoxic activity of two series of platinum(II) complexes containing the polyfunctional imines R1–CHN–R2 [R1 = phenyl or ferrocenyl unit and R2 = (CH2)n–CH2–NMe2 where n = 1 or 2) (1 and 2) or C6H4-2-SMe (3)] acting as a bidentate (N,N′) (4–7) or terdentate [C(phenyl or ferrocenyl),N,N′]− (8–10) or [C(ferrocenyl),N,S]− ligand (11) in front of A549 lung, MDA-MB231 breast and HCT116 colon human
含有多官能亚胺R 1 –CH N–R 2 [R 1 =苯基或二茂铁基单元,R 2 =(CH 2)n –CH 2 –NMe 2,其中n = 1或2)(1和2)或C 6 H ^ 4 -2-SME(3)]作为二齿(N,N')(4 - 7)或terdentate [C(苯基二茂铁基或),N,N- ′] −(8 – 10)或[C(二茂铁基),N,S] −据报道,在A549肺,MDA-MB231乳腺和HCT116结肠人类腺癌细胞系之前存在配体(11)。结果表明,大部分的铂(II)配合物是针对这三种测定线活性和化合物6,7和platinacycles 10和11表现出显着的抗增殖活性,甚至大于顺铂本身,在顺铂抗性HCT116人类癌细胞线。电泳DNA迁移研究表明,它们大多数以与参考顺铂相似的方式修饰DNA三级结构。为了测试:(a)它们在水性生物介质中的稳定性和/或生物活性物质的形成,以及(b)它们与
