Anticancer activity of opened arene ruthenium metalla-assemblies.

Combining coordination and hydrogen-bonds to form arene ruthenium metalla-assemblies

Three ureido-pyrimidone derivatives (N-LH) were used to generate in combination with four dinuclear arene ruthenium clips, (p-cymene)2Ru2(OO∩OO)Cl2 (OO∩OO 1⁄4 oxalato, 2,5-dioxido-1,4-benzoquinonato, 2,5-dichloro-1,4-benzoquinonato, 5,8-dioxido-1,4-naphtoquinonato), twelve cationic arene ruthenium metalla-cycles of the general formula [(p-cymene)2Ru2(OO∩OO)(N-L)2]2(CF3SO3)4. The ureidopyrimidon...

From Anticancer Complexes to Photoswitchable Assemblies: New Approaches in the Design and Synthesis of Arene Ruthenium Species

Interactions of arene ruthenium metallaprisms with human proteins.

Interactions between three hexacationic arene ruthenium metallaprisms, [(p-cymene)6Ru6(tpt)2(dhnq)3](6+), [(p-cymene)6Ru6(tpt)2(dhbq)3](6+) and [(p-cymene)6Ru6(tpt)2(oxa)3](6+), and a series of human proteins including human serum albumin, transferrin, cytochrome c, myoglobin and ubiquitin have been studied using NMR spectroscopy, mass spectrometry and circular dichroism spectroscopy. All data ...

Investigation of the biological and anti-cancer properties of ellagic acid-encapsulated nano-sized metalla-cages

Three new large hexanuclear metalla-prisms 9-11 incorporating 1,3, 5-tris(pyridin-4-ylethynyl)benzene (tpeb) 4 and one of the dinuclear arene ruthenium clips [Ru2(p-iPrC6H4Me)2(OO∩OO)][CF3SO3]2 (OO∩OO =2,5-dioxydo-1,4-benzoquinonato [dobq] 1, 5,8-dihydroxy-1,4-naphthaquinonato (donq) 2, and 6,11-dihydroxy-5,12-naphthacenedionato [dotq] 3), which encapsulate the guest molecule ellagic acid (2,3,...

Template-Directed Synthesis of Hexanuclear Arene Ruthenium Complexes with Trigonal- Prismatic Architecture Based on 2,4,6-Tris(3-pyridyl)triazine Ligands

Cationic arene ruthenium metalla-prisms of the general formula [Ru6(p-cymene)6(3-tpt)2-(OO∩OO)3] (3-tpt = 2,4,6tris(3-pyridyl)-1,3,5-triazine; OO∩OO = 5,8-dioxido-1,4-naphthoqui-nonato [1]6þ or 6,11-dioxido-5,12naphthacenedionato [2]6þ) have been obtained from the corresponding dinuclear arene ruthenium complexes [Ru2(pcymene)2(OO∩OO)Cl2] by reaction with 3-tpt, silver trifluoromethanesulfonate...
