DDR1-IN-2 is primarily used in research settings to study the role of discoidin domain receptor 1 (DDR1) in various biological processes. It serves as a selective inhibitor of DDR1, a receptor tyrosine kinase involved in cell adhesion, migration, and extracellular matrix remodeling. Researchers utilize DDR1-IN-2 to investigate its potential therapeutic effects in diseases where DDR1 plays a significant role, such as cancer, fibrosis, and inflammatory disorders. In cancer studies, it helps to understand how inhibiting DDR1 can impact tumor growth, metastasis, and resistance to treatments. Additionally, it is explored in fibrosis research to assess its ability to reduce tissue scarring in organs like the lungs, liver, and kidneys. DDR1-IN-2 is also used in preclinical models to evaluate its efficacy and safety as a potential drug candidate for these conditions.
