Functions

Pexidartinib (1029044-16-3) is a potent and selective dual inhibitor of CSF1R (IC50 = 20nM) and c-KIT (IC50 = 10nM). Inhibition of CSF1R with Pexidartinib resulted in a reprogrammed immune microenvironment that fosters antitumor immunity in a CD8+ T-cell-dependent manner in a breast cancer model.1 CSF1R recruits tumor-infiltrating myeloid cell that suppress tumor immunity – Pexidartinib increased the efficacy of adoptive cell immunotherapy (ACT) in a mouse melanoma model by inhibiting the intratumoral accumulation of immunosuppressive macrophages. It has also been shown to increase the efficacy of anti-PD-1 and DC immunotherapy.

 

Application Procedures

First dissolved in DMSO (up to at least 10 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 2 months.
