Mechanism of action

As an acridine derivative, proflavine intercalates between DNA base pairs, disrupting replication and transcription. It also generates reactive oxygen species that damage cellular components. Historically used as a topical antiseptic and antimicrobial agent, it has been investigated for anticancer properties due to its ability to inhibit cell proliferation and induce oxidative stress in tumor cells.
