ligand coordinated to the copper(I) ion resulted in a relevant increase of cytotoxicity in the case of breast, pancreatic and prostate tumor cell lines in vitro. Attachment of a peptide carrier significantly increased the selectivity towards cancer cells. Fluorescence spectroscopic data (calf thymus DNA: CT-DNA) titration), together with analysis of DNA fragmentation (gel electrophoresis) and molecular
磷盐(p-OCH3-Ph)2P(CH2OH)2Cl(MPOHC),衍生的膦配体,不含和带有SarGly(Sarcosine-Glycine)肽载体P(p-OCH3-Ph)2CH2OH(MPOH)和P(p-OCH3 -Ph)2CH2SarGly(MPSG)和两个铜(I)络合物[Cu(I)(dmp)(MPOH)](1-MPOH; dmp =(2,9-二甲基-1,10-菲咯啉))合成了[Cu(I)(dmp)(MPSG)](1-MPSG)。通过元素分析,1D和2D NMR和UV-Vis吸收光谱,质谱,循环伏安法以及X射线衍射分析对所得化合物进行表征。在体外评估了所有化合物对结肠,肺,乳腺,胰腺,前列腺肿瘤细胞系以及对非肿瘤细胞系(肺,肾和角质形成细胞)的细胞毒性。在有氧气存在的生物介质中稳定,Cu(I)复合物对被测癌细胞系的细胞毒性作用高于顺铂引发的细胞毒性作用。在体外对乳腺,胰腺和前列腺肿瘤细胞
