TY-52156 is a selective antagonist of the sphingosine-1-phosphate receptor 3 (S1P3), primarily researched for its potential in modulating cardiovascular function, inflammation, and immune responses. By blocking S1P3 receptors, it influences vascular tone, endothelial barrier integrity, and immune cell migration, making it a candidate for studying conditions such as hypertension, atherosclerosis, and inflammatory disorders. Ongoing research explores its therapeutic efficacy and safety profile in preclinical models.
