Pexidartinib (Synonyms: PLX-3397)

Cat. No.: HY-16749 Purity: 99.64%
Handling Instructions

Pexidartinib (PLX-3397) is a potent, orally active, selective, and ATP-competitive colony stimulating factor 1 receptor (CSF1R or M-CSFR) and c-Kit inhibitor, with IC50s of 20 and 10 nM, respectively. Pexidartinib (PLX-3397) exhibits 10- to 100-fold selectivity for c-Kit and CSF1R over other related kinases. Anti-tumor activity.

Description

Pexidartinib (PLX-3397) is a potent, orally active, selective, and ATP-competitive colony stimulating factor 1 receptor (CSF1R or M-CSFR) and c-Kit inhibitor, with IC50s of 20 and 10 nM, respectively. Pexidartinib (PLX-3397) exhibits 10- to 100-fold selectivity for c-Kit and CSF1R over other related kinases. Anti-tumor activity[1].

IC50 & Target

IC50: 10 nM (c-Kit), 20 nM (cFMS), 160 nM (FLT3), 350 nM (KDR), 860 nM (LCK), 880 nM (FLT1), 890 nM (NTRK3)[1]

In Vitro

Pexidartinib (PLX-3397) 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[1].

In Vivo

Pexidartinib (PLX3397; 0.25, 1 mg/kg, twice daily for 8 days) inhibits the proliferation of microglia and BrdU-positive cells in neonatal mice[2]. Pexidartinib (1 mg/kg, twice daily for 8 day) shows no obvious effect on the cleaved caspase-3-positive cells in mice[2].

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.
