Proflavine Hemisulfate, the hemisulfate form of proflavin, is an acridine-derived fluorescent contrast agent and disinfectant used for cell imaging and antiseptic purposes. Following topical application, proflavin diffuses into cells and intercalates into DNA, leading to its accumulation in and staining of the nucleus. This allows visualization of the nucleus during fluorescence imaging. Such capability enables nuclear morphometry and facilitates the identification of cancer cells. Additionally, proflavin sulfate exerts antimicrobial effects through binding to bacterial DNA, which disrupts DNA synthesis and inhibits bacterial cell growth.
orange to brown crystalline powder
An Acridine derivative with limited antifungal activity
Proflavine Hemisulfate is used in preparation of Adenine and Adenine nucleotides via photochemical demethylation of methyladenines.
An aqueous solution, after treatment with charcoal, is concentrated, chilled overnight, filtered and the precipitate is rinsed with a little diethyl ether. The precipitate is dried in air, then overnight in a vacuum oven at 70o. [Beilstein 22 I 650, 22/11 V 323.]
