RS102895 hydrochloride is primarily used in research settings to study the role of chemokine receptors in various biological processes. It acts as a selective antagonist for the CCR2 receptor, which is involved in the migration of monocytes and macrophages. This makes it a valuable tool for investigating inflammatory diseases, such as rheumatoid arthritis, atherosclerosis, and multiple sclerosis, where CCR2 signaling plays a critical role. Researchers also utilize it to explore its potential in modulating immune responses in cancer and other conditions linked to immune cell recruitment. Its application extends to preclinical studies aimed at developing therapeutic strategies targeting the CCR2 pathway.
