A novel azopyridine-based Ru(ii) complex with GSH-responsive DNA photobinding ability†
Abstract
A novel azopyridine-based Ru(II) complex [Ru(bpy)2(L1)2]2+ (bpy = 2,2′-bipyridine, L1 = 4,4′-azopyridine) was designed and synthesized as a potential glutathione (GSH)-responsive photoactivated chemotherapy (PACT) agent, the DNA covalent binding capability of which can only be activated after GSH reduction and visible light irradiation.
