Used primarily as a selective antagonist for the CCR5 chemokine receptor, this compound serves as a valuable tool in research related to HIV infection, as CCR5 plays a key role in viral entry into host cells. It helps in studying receptor function and blocking chemokine-mediated signaling in immune cells. Due to its specificity, it is employed in experimental models to investigate inflammatory responses, autoimmune diseases, and potential therapeutic strategies targeting CCR5 pathways. Its application remains confined to laboratory and preclinical research settings.
