(A) Administration
of 5 inhibits serum AFP secretion
in vivo. Mice were treated for 27 days, 3 times a week, starting 3
weeks following HCC transplantation with two doses of 1 (0.1 mg/kg [2 μg], green bars or 1 mg/kg [20 μg], red
bars), compared with untreated controls (blue bars). Levels are normalized
to the starting day of therapy. (B) Compound 5 diminishes
tumor volume in both treated groups (0.1 mg/kg [2 μg], green
bars and 1.0 mg/kg [20 μg], red bars) compared to untreated
controls (blue bars). Figure reproduced from ref (35). Copyright 2015 American
