How to use

In Vitro:

Pexidartinib hydrochloride (PLX-3397 hydrochloride) is a potent, selective and ATP-competitive CSF1R (cFMS) and c-Kit inhibitor, shows 10- to 100-fold selectivity for c-Kit and CSF1R over other related kinases, such as FLT3, KDR (VEGFR2), LCK, FLT1 (VEGFR1) and NTRK3 (TRKC), with IC50s of 160, 350, 860, 880, and 890 nM, respectively.

In Vivo:

Pexidartinib hydrochloride (0.25, 1 mg/kg, i.p., twice daily for 8 days) inhibits the proliferation of microglia and BrdU-positive cells in neonatal mice. Pexidartinib hydrochloride (1 mg/kg, twice daily for 8 day) shows no obvious effect on the cleaved caspase-3-positive cells in mice. Pexidartinib hydrochloride (50 mg/kg; p.o.; every second day for 3 weeks) reduces tissue macrophage levels without affecting glucose homeostasis in mice.
