摘要：The development of novel sonosensitizers with safety and efficiency is a key problem in anti-tumor sonodynamic therapy. Phycocyanin (PC) has been proved to have the singlet oxygen radicals (ROS) generation ability, and the potential of PC as a novel sonosensitizer has been investigated. To overcome the disadvantages of PC in vivo, such as poor stability and low half-life, PC nanoparticles (PCNP) were prepared by the cross-linking method. According to the results, PCNP has been found with good morphology, good particle size distribution and good stability. Human breast cancer cell line MCF-7 was used to investigate PCNP cell uptake ability. ROS generation and cytotoxicity under ultrasonic irradiation (sonotoxicity) were also studied on this cell. Under the condition of 0.75 w/cm2 ultrasound, PCNP has a good ROS productivity and is equivalent to the sonotoxicity of the known sonosensitizer hematoporphyrin monomethyl Ether (HMME). In conclusion, PCNP is expected to be developed as an effective sonosensitizer for the sonodynamic therapy of tumors.
