Pexidartinib hydrochloride (PLX-3397 hydrochloride) is a potent, orally active, selective, and ATP-competitive colony stimulating factor 1 receptor (CSF1R or M-CSFR) and c-Kit inhibitor, with IC 50 s of 20 and 10 nM, respectively. Pexidartinib hydrochloride exhibits 10- to 100-fold selectivity for c-Kit and CSF1R over other related kinases. Pexidartinib hydrochloride induces cell apoptosis and has anti-cancer activity [1] .
IC50: 10 nM (c-Kit), 20 nM (cFMS), 160 nM (FLT3), 350 nM (KDR), 860 nM (LCK), 880 nM (FLT1), 890 nM (NTRK3) [1]

Animal Model: | Neonatal mice [2] |
Dosage: | 0.25, 1 mg/kg |
Administration: | I.P. twice daily for 8 days |
Result: | Decreased the number of microglia and BrdU-positive proliferative cells, but did not change the cleaved caspase-3-positive cells. |
Animal Model: | 10-week old litter mate C57BL/6 mice (chow and high-fat diet fed mice) [4] |
Dosage: | 50 mg/kg |
Administration: | P.o.; every second day for 3 weeks |
Result: | Substantially reduced macrophage numbers in adipose tissue of both chow and high-fat diet fed mice without affecting total myeloid cell levels. |
