Core Tip

Core tip: Photodynamic therapy (PDT) has become a feasible treatment for advanced pancreatic neoplasms. Photosensitizers play a critical role in PDT. (17R,18R)-2-(1-hexyloxyethyl)-2-devinyl chlorine E6 trisodium salt (YLG-1) is a promising photosensitizer with high water solubility and phototoxicity. The functions of YLG-1-induced PDT (YLG-1-PDT) are still poorly understood. We found that YLG-1-PDT displayed great antitumor effects on pancreatic cancer cells in vitro and in vivo, the mechanisms of which involved inducing reactive oxygen species and promoting apoptosis. The optimal administration of YLG-1 towards pancreatic cancer is an intratumoral injection. Our study suggests that YLG-1 is a potential photosensitizer for pancreatic neoplasm PDT.
