10 μM PF-429242 down-regulates the signal from an SRE-luciferase reporter gene in human embryonic kidney 293 cells and the expression of endogenous SREBP target genes in cultured HepG2 cells. In HepG2 cells, PF-429242 inhibits cholesterol synthesis, with an IC50 of 0.5 μM[1]. PF-429242 treatment also shows suppressive effects on DENV2 yields in the cultured fluids of human-derived HEK-293, Hep G2, and non-human-primate derived LLC-MK2 cells[2]. PF-429242 has potent antiviral against LCMV and LASV [3].

PF-429242 inhibits the expression of hepatic SREBP target genes, and the hepatic rates of cholesterol and fatty acid synthesis are reduced In mice[1].
