CSF1R-IN-3 (compound 21) is a potent and orally active CSF-1R inhibitor (IC50=2.1 nM). CSF1R-IN-3 is a potent antiproliferative activity against colorectal cancer cells. CSF1R-IN-3 inhibits the progression of colorectal cancer by suppressing the migration of macrophages, reprograming M2-like macrophages to the M1 phenotype, and enhancing the antitumor immunity[1].
