Title A novel photosensitizer based on hypocrellin B activated by cysteine over-expressed in cancer cells.
Journal Org Biomol Chem
Abstract L-Cysteine (Cys)-activatable photosensitizer 3 was designed and synthesized based on hypocrellin B (1). Cys is a novel tumor-associated biomarker. 3 exhibited negligible photosensitizing ability without Cys. However, when 1 was released from 3 by reaction with Cys, the photosensitizing activity was restored. Furthermore, 3 showed selective and effective photo-cytotoxicity against only cancer cells such as HeLa and A549 cells that highly express Cys when irradiated with 660 nm light, which is inside the phototherapeutic window.
