Biological Activity
IC50: 175 nM (S1P)[1]
10 μM PF-429242 inhibits endogenous SREBP processing in Chinese hamster ovary cells. PF-429242 also 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].
The addition of PF-429242 (30 μM) shows statistically significant suppression of infectious viral titers and viral RNA copies in the cell culture fluids. 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 efficiently prevents the processing of GPC from the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV) and LASV, which correlates with the compound's potent antiviral activity against LCMV and LASV in cultured cells[3].

This product has good water solubility, please refer to the measured solubility data in water/PBS/Saline for details.
Protocol
Mice: To test the in vivo efficacy of PF-429242 in regulating SREBP target genes, male CD1 mice are dosed i.p. with 10 or 30 mg/kg PF-429242 or saline once every 6 over a 24-h period. Mice are euthanized 6 h after the final dose, and liver tissue is collected, frozen rapidly in liquid nitrogen, and stored at -80°C. For RNA isolation, 50 to 100 mg of frozen liver tissue from each sample is homogenized in 1 ml of TRIzol reagent. Total RNA is extracted following the manufacturer's instructions, and the resulting total RNA from each sample underwent DNA-free treatment[1].
