THPN is a Nur77 agonist. THPN binds Nur77 and promotes translocation of the receptor to the mitochondria resulting in autophagy in melanoma cell lines.
THPN or 1-(3,4,5-Trihydroxyphenyl)nonan-1-one, is a derivative of cytosporone B.
THPN is potent nuclear receptor TR3 (Nur77) antagonist that induces autophagic cell death in melanoma. Co-application of THPN with Akt2 inhibitors significantly represses tumor growth in xenograft mouse model.
