Light-induced HeLa cytotoxicity from ruthenium complexes. When HeLa cells were treated with [Ru(bpy)2(66′bpy(OH)2)]2+ or irradiated at 450 nm for 1 hour little cell death occurred. In contrast, when cells were treated with [Ru(bpy)2(66′bpy(OH)2)]2+ and 450 nm irradiation viability dropped to 47%. Controls using [Ru(bpy)2(44′bpy(OH)2)]2+ and [Ru(bpy)3]2+ showed limited cell death, even with irradiation. (−) Indicates no irradiation and (+) indicates irradiation at 450 nm for 1 hour.
