Naphthofluorescein

Synonyms: Naphthafluorescein

Naphthofluorescein is a potent inhibitor of HIF-1 through the inhibition of HIF prolyl-hydroxylase activity. It effectively suppresses Mint3-dependent HIF-1 signaling and glycolytic activity in cancer cells and macrophages while exhibiting low cytotoxicity in vitro and negligible adverse effects in vivo. Additionally, Naphthofluorescein serves as a fluorescent pH-sensitive probe, making it suitable for functional Cerenkov imaging applications.
