GPA512
GPA512 is an orally active STAT3 inhibitor and a prodrug of Galiellalactone (HY-125170). GPA512 inhibits the binding of STAT3 to DNA, downregulates STAT3-activated genes, and suppresses tumor growth in prostate cancer xenograft models. GPA512 is rapidly converted to Galiellalactone in plasma. GPA512 can be used in research related to castration-resistant prostate cancer.

In Vitro
GPA512 (5 μM; monitored over 0-120 min) exhibits moderate symmetric permeability across Caco-2 cell monolayers, with no directional preference between absorptive and secretive transport[2].
GPA512 (10 μM; 2 h) is completely metabolized by mouse hepatocytes within 2 h, primarily via ester hydrolysis to form carboxylic acid (compound 3), which then spontaneously converts to Galiellalactone[2].
