Abstract
Acting as an extracellular matrix protein receptor, αVβ3 integrin becomes an appealing target for photodynamic therapy of bladder cancer. Here, specific αVβ3-integrin-targeting porphyrinato-gadolinium complexes (Gd-PEG-Rn) are demonstrated as off-on theranostic agents, where Rn are specific peptides. Among them, Gd-PEG-R3 shows both impressive phototherapeutic index and robust in vivo magnetic resonance imaging (MRI) signal enhancement. Significant selectivity of Gd-PEG-R3 is proven by its high αVβ3 integrin binding affinity in positive bladder cancer cells. All these findings support Gd-PEG-R3 as a promising bi-functional medical agent with both MRI contrasting ability and photodynamic therapeutic potential for curing bladder cancer.
