Abstract
In clinics, for photodynamic therapy (PDT) it is challenging to achieve photosensitizers with properties of high singlet oxygen quantum yield, tumor targeting and fluorescence imaging simultaneously. Herein, a furan flanked diketopyrrolopyrrole (FDPP) molecule, with good singlet oxygen quantum yield (∼26%), is covalently connected to hyaluronic acid (HA) to obtain a water-soluble photosensitizer (FDPP-HA), which presents good specific targeting to HCT-116 tumor cells both in vitro and in vivo. FDPP-HA also exhibits excellent biocompatibility, low dark toxicity and high phototoxicity, which can effectively inhibit the tumor growth in vivo by PDT. The design of FDPP-HA in this work provides a general strategy for cancer target-specific fluorescence imaging and PDT.
