of breast cancer cells. To delineate the mechanism of action, computer-aided analyses (DFT calculations) were conducted for compound 13. Results indicate that in vivo, the pyridineamine ligands are likely to dissociate from the complex, forming a platinum DNA adduct with anti-proliferative activity. These results suggest that complexes 13 and 14 hold promise as potential anti-cancer agents.
尽管顺铂被认为是一种有效的抗癌剂,但它已显示出局限性并可能对患者产生毒性。因此,我们合成了两种顺-dichlorideplatinum(II)的化合物(13和14组成)的元-和对位- Ñ,ñ -二苯基吡啶胺配体通过胺前体的反应和氯铂酸2用的16和47%的相应的产量。我们假设具有亲脂性配体的化合物13和14应该在癌细胞中有效转运,并且比顺铂更有效。当测试生物活性时,化合物发现13和14抑制 MCF 7 和 MDA-MB-231 细胞的生长(IC 50s 1 ± 0.4 µM 和 1 ± 0.2 µM分别用于13和14,IC 50 7.5 ± 1.3 µM 用于化合物13和 1 ± 0.3 µM 对于化合物14 )。顺便说一下,发现这些剂量低于顺铂剂量(MCF 7 的IC 50 5 ± 0.7 µM 和 MDA-MB-231 的IC 50 ± 1.1 µM)。类似于顺铂,13和14与 DNA
