Synthesis, characterisation and in vitro cytotoxicity studies of a series of chiral platinum(II) complexes based on the 2-aminomethylpyrrolidine ligand: X-ray crystal structure of [PtCl2(R-dimepyrr)] (R-dimepyrr=N-dimethyl-2(R)-aminomethylpyrrolidine)

A series of platinum(II) complexes were synthesised based on the enantiomerically pure amino acid proline. Novel synthetic pathways were developed, adapted from standard peptide chemistry, to produce the 2-aminomethylpyrrolidine (pyrr) ligand and its derivatives with differing arrangements of methyl substituents at the exocyclic amine sites. The crystal structure of [PtCl2(R-dimepyrr)] (R-dimepyrr = N
基于对映体纯的氨基酸脯氨酸合成了一系列铂(II)配合物。根据标准肽化学,开发了新的合成途径,以产生2-氨基甲基吡咯烷(pyrr)配体及其衍生物,其在环外胺位点具有不同的甲基取代基排列。[PtCl 2(R -dimepyrr)](R -dimepyrr = N,N-二甲基-2(R)-氨基甲基吡咯烷),并且五元配体环已显示为包膜构象。对卵巢癌A2780肿瘤细胞系及其顺铂耐药变体A2780cisR进行了细胞毒性研究。尽管胺基团增加了很大的空间体积,但与顺铂相比,几种药物仍具有显着的良好活性,并且某些化合物与顺铂缺乏交叉耐药性。
