Synthesis, Molecular Structure, and Anticancer Activity of Cationic Arene Ruthenium Metallarectangles

Mattsson, Johan ; Govindaswamy, Padavattan ; Renfrew, Anna K. ; Dyson, Paul J. ; Štěpnička, Petr ; Süss-Fink, Georg ; Therrien, Bruno

In: Organometallics, 2009, vol. 28, no. 15, p. 4350–4357

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...
