CSF1R-IN-6 is a potent inhibitor of CSF1R. CSF-1R is expressed in macrophages, and the survival and differentiation of macrophages depends on the CSF-1/CSF-1R signaling pathway. CSF1R-IN-6 affects the exchange of inflammatory factors between TAMs and glioma cells. CSF1R-IN-6 has the potential for the research of cancer disease (extracted from patent WO2021197276A1, compound 5).
