(PF6)2

[Ru(dpp)(bpy)(mtmp)](PF6)2 (Compound 5) is a trisheteroleptic ruthenium complex. [Ru(dpp)(bpy)(mtmp)](PF6)2 has a light-activated anticancer activity. [Ru(dpp)(bpy)(mtmp)](PF6)2 can selectively cleave off upon green light irradiation, thereby releasing a phototoxic ruthenium-based photoproduct that binds to nuclear DNA, induces DNA damage and apoptosis in cancer cells. [Ru(dpp)(bpy)(mtmp)](PF6)2 can be used for phototherapy of cancers like conjunctival melanoma research.
