SL-017

Description

SL-017 is a novel photoacoustic sensitizer and a derivative of photofrin B. It can be taken up by cells to the maximum extent within 30 minutes and is mainly localized in mitochondria. After being activated by visible light or ultrasound, SL-017 can significantly increase the production of reactive oxygen species ROS . Low concentrations of SL-017 can rapidly cause the loss of mitochondrial membrane potential. SL-017 can also cause mitochondrial fragmentation, a process that occurs after the loss of membrane potential. Epoxyeicosatrienoic acids EETs can alleviate the loss of mitochondrial membrane potential caused by SL-017, but the antioxidant ascorbic acid has no such effect. These characteristics indicate that SL-017 mainly targets mitochondria and exerts its cytotoxic effect by triggering the collapse of mitochondrial membrane potential, generating ROS, and causing mitochondrial fragmentation. As a novel photoacoustic sensitizer, SL-017 has potential application value in photodynamic therapy and sonodynamic therapy.
