Used in phototherapy for skin disorders such as psoriasis and vitiligo due to its ability to intercalate DNA and become activated by UVA light, leading to inhibition of excessive cell proliferation. Also investigated for its antifungal and antibacterial properties, particularly in combination with light exposure (photodynamic therapy). Shows potential in research for targeted cancer treatments because of its photoinducible cytotoxic effects on certain tumor cells. Additionally, utilized in molecular biology as a DNA cross-linking agent upon irradiation, aiding in the study of DNA structure and repair mechanisms.
