SAR-100842 is primarily investigated for its potential therapeutic applications in the field of medicine. It is being studied for its role in treating fibrotic diseases, particularly systemic sclerosis, due to its ability to modulate lysophosphatidic acid (LPA) receptor signaling. By inhibiting LPA1 receptors, it may help reduce fibrosis and improve tissue remodeling. Additionally, its anti-fibrotic properties are being explored in other conditions involving excessive scarring or tissue damage, such as lung and liver fibrosis. Research is ongoing to evaluate its efficacy and safety in clinical settings.
