CSF-1R

Pimicotinib hydrochloride is a selective inhibitor of the colony-stimulating factor 1 receptor (CSF1R), demonstrating an IC50 value of 19.48 nM in inhibiting ADP production. This compound exhibits notable anti-tumor activity, making it a valuable tool for research in cancer biology and immunotherapy. Its specificity for CSF1R provides insights into the modulation of macrophage activity in the tumor microenvironment.

OSI-930 is a potent inhibitor of Kit, KDR, Flt, CSF-1R, c-Raf and Lck with IC50 of 80 nM, 9 nM, 8 nM, 15 nM, 41 nM and 22 nM, respectively.

Sulfatinib (HMPL-012) is a potent and highly selective tyrosine kinase inhibitor against VEGFR1/2/3, FGFR1 and CSF1R with IC50s of in a range of 1 to 24 nM.

Pexidartinib hydrochloride is a potent, orally active inhibitor of the colony stimulating factor 1 receptor (CSF1R) and c-Kit, demonstrating ATP-competitive activity with IC50 values of 20 nM and 10 nM, respectively. This compound exhibits selective inhibition, with 10- to 100-fold potency over other related kinases. Pexidartinib hydrochloride promotes apoptosis in affected cells and exhibits significant anti-cancer properties, making it a valuable tool for research in oncology and immunology.
