RuII -arene complexes provide a versatile scaffold for novel anticancer drugs. Seven new RuII -arene-thiocarboxylato dimers were synthesized and characterized. Three of the complexes (2 a, b and 5) showed promising antiproliferative activities in MDA-MB-231 (human invasive breast cancer) cells, and were further tested in a panel of fifteen cancerous and noncancerous cell lines. Complex 5 showed moderate
RuII-
芳烃配合物为新型抗癌药物提供了多功能支架。合成并表征了七个新的RuII-
芳烃-
硫代羧酰二聚体。三种复合物(2a,b和5)在
MDA-MB-231(人类浸润性乳腺癌)细胞中显示出有希望的抗增殖活性,并在一组15种癌性和非癌性
细胞系中进行了进一步测试。复合物5在
MDA-MB-231细胞中表现出中等但显着的选择性活性(IC50 = 39±4μmRu)。实时增殖研究表明5诱导了
MDA-MB-231细胞凋亡,但对A549(人肺癌,上皮)细胞无影响。相比之下,2 a和b在这两种
细胞系中均显示出中等的抗增殖活性,但没有凋亡。侵袭性细胞的选择性细胞毒性为5,
