1,3a,6a-Triazapentalene derivatives as photo-induced cytotoxic small fluorescent dyes

Abstract

Photoactive dyes can show promising cytotoxicity via reactive oxygen species generated by photoirradiation, however, the cytotoxicity of small molecule dyes is typically weak. Here, the authors develop 1,3a,6a-triazapentalene derivatives exhibiting selective and efficient photo-induced cytotoxicity.
