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...
