CSF1R-IN-1 is primarily used in research settings to study its inhibitory effects on the colony-stimulating factor 1 receptor (CSF1R). This receptor plays a crucial role in the regulation of macrophages and other mononuclear phagocytes, making CSF1R-IN-1 a valuable tool in understanding diseases where these cells are implicated.

In cancer research, CSF1R-IN-1 is employed to investigate tumor microenvironments, particularly the role of tumor-associated macrophages (TAMs). By inhibiting CSF1R, it helps researchers explore how reducing TAM activity affects tumor growth, metastasis, and response to therapies.

Additionally, CSF1R-IN-1 is used in studies related to inflammatory and autoimmune diseases. Its ability to modulate macrophage activity provides insights into conditions like rheumatoid arthritis, multiple sclerosis, and other disorders where immune cell dysregulation is a key factor.

Overall, CSF1R-IN-1 serves as a critical compound in preclinical studies, aiding in the development of targeted therapies for cancer and immune-related diseases.
