GPR84 antagonist 8 is primarily used in research settings to study the role of GPR84 receptors in various biological processes. This compound is particularly valuable in understanding inflammation and immune responses, as GPR84 is known to be involved in these pathways. By inhibiting the receptor, researchers can investigate its impact on conditions such as chronic inflammation, autoimmune diseases, and metabolic disorders. Additionally, it serves as a tool for developing potential therapeutic agents targeting GPR84-related diseases. Its application extends to preclinical studies aimed at exploring new treatments for inflammatory and immune-mediated conditions.
