The cytotoxicities of a new series of cationic metallarectangles have been established in the A2780 ovarian cancer cell line. Interestingly, the large rectangles incorporating 1,2-bis(4-pyridyl)ethylene linkers are ca. 5 times more cytotoxic (IC50 ≤ 6 μM) than the 4,4-bipyridine analogues (IC50 ≥ 30 μM), thus suggesting a correlation between cytotoxicity and the size...

The rational development of multinuclear arene ruthenium complexes (arene = p-cymene, hexamethylbenzene) from generation 1 (G1) and generation 2 (G2) of 4-iminopyridyl based poly(propyleneimine) dendrimer scaffolds of the type, DAB-(NH2)n (n = 4 or 8, DAB = diaminobutane) has been accomplished in order to exploit the ‘enhanced...

New Dinuclear Ru2(CO)4 Sawhorse-Type Complexes Containing Bridging Carboxylato Ligands

Auzias, Mathieu ; Mattsson, Johan ; Therrien, Bruno ; Süss-Fink, Georg

In: Zeitschrift für anorganische und allgemeine Chemie, 2008, vol. 635, no. 1, p. 115-119

The thermal reaction of Ru3(CO)12 with ethacrynic acid, 4-[bis(2-chlorethyl)amino]benzenebutanoic acid (chlorambucil), or 4-phenylbutyric acid in refluxing solvents, followed by addition of two-electron donor ligands (L), gives the diruthenium complexes Ru2 (CO)4(O2CR)2L2 (1: R =...
