Tumor-associated macrophages (TAMs) are predominantly associated with tumor growth. Colony-stimulating factor 1 receptor (CSF1R) acts as a key regulator of TAM survival and differentiation and is a molecular target for cancer therapies. Herein, novel CSF1R inhibitors were identified through a replacement strategy for the hinge-binding moiety. The introduction of imidazo[1,2-a]pyridine (49) or pyrazolo[1
