Bioactivity CSF1R-IN-22 (Compound C19) is an orally effective CSF-1R selective inhibitor (IC50<6 nM). CSF1R-IN-22 enhances the secretion of CXCL9 from M2 macrophages, increases CD8+ T cell infiltration. CSF1R-IN-22 boosts anti-tumor immune responses of anti-PD-1, and induces apoptosis in tumor cells. CSF1R-IN-22 can effectively reprogram M2-like TAMs (tumor-associated macrophages) to the M1 phenotype and reshape the TME by inducing the recruitment of CD8+ T cells into tumors and reducing the infiltration of immunosuppressive Tregs and MDSCs[1].
Invitro CSF1R-IN-22 (0-2500 nM; 1 h) 显著抑制 BMDMs 细胞中的 CSF-1R 信号通路的激活[1]。CSF1R-IN-22 (30-100 nM; 24 h) 能够有效地将 BMDMs 细胞和 HMDMs 细胞中的 M2 型巨噬细胞重新编程为 M1 型巨噬细胞[1]。CSF1R-IN-22 (10-100 nM; 20 h) 处理的 M2 型巨噬细胞上清液显著抑制了 MC-38 和 CT-26 细胞的活力[1]。 MCE has not independently confirmed the accuracy of these methods.
