The complex [RuCp(PPh3)2(HdmoPTA)](OSO2CF3)2 (2; HdmoPTA = 3,7-H-3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane) was synthesized and characterized. Its crystal structure was determined by single-crystal X-ray diffraction. The complex showed a more potent antiproliferative activity than cisplatin against a representative panel of human cancer cells.
Synthesis, characterization and the antiproliferative activity of a new bimetallic complex [RuCp(PPh)-μ-dmoPTA-1κP:2kN,N'-CoCl]OTf·0.25HO are described. The stability of the complex was studied under air and N atmospheres and in CDCl, DMSO, water and the cell culture medium, at room temperature and 40 °C. The complex showed an enhanced antiproliferative activity (up to six-fold) when compared with its parent complex [RuCp(PPh)(HdmoPTA)] against human lung, cervix, breast, and colon solid tumor cell lines.
The synthesis, characterization and antiproliferative activity of the bimetallic Ru-Zn complex [RuCp(PPh 3 ) 2 -μ-dmoPTA-1κP:2κ 2 N,N′-ZnCl 2 ](CF 3 SO 3 ) (4) and the monometallic Ru complex [RuCp(PPh 3 ) 2 (dmoPTA-1κP)](CF 3 SO 3 ) (5) are presented. Against human lung, cervix, breast, and colon solid tumor cell lines, complex 4 showed an enhanced antiproliferative activity (GI 50 = 30-83 nM) when compared to its parent complex [a]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
