In vitro study of YLG-1 mediated photodynamic effect on human cancer cells

Photosensitizer is a key element of photodynamic therapy (PDT). Currently, only limited numbers of photosensitizers are available for antitumor PDT in China. YLG-1 (Ang-Da-Fen-Qi) is a newly developed second-generation chlorin-type photosensitizer. In this preliminary study, the killing effect of combination of YLG-1 and 652 nm diode laser on human nasopharyngeal carcinoma cells and human ovarian cancer cells were investigated. In vitrostudy suggests that YLG-1 mediated PDT activity has strong cancer cell killing effect and therefore potentials for antitumor PDT applications.
