Abstract

The discovery of new photosensitizer drugs with long wavelength Uv-vis absorption, high efficiency and low side-effects is still a challenge in photodynamic therapy. Here a series of novel meso-substitutedphenyl thieno[3,2-b]thiophene-fused BODIPY derivatives were designed, synthesized and characterized. All these compounds have strong absorption at 640-680 nm and obvious fluorescence emission at 650-760 nm. They exhibited high singlet oxygen generation ability and significant photodynamic efficiency against Eca-109 Cancer cells. Compounds II4, II6, II9, II10 and II13 could generate intracellular ROS and induce cell Apoptosis after laser irradiation, which displayed superior photodynamic efficiency against Eca-109 cells than Temoporfin in vitro and in vivo. Among them, compound II4 specifically exhibited excellent anti-tumor efficacy, and could be selected as a new drug candidate for PDT.
