VPC 23019(Cat No.:I010015)is a potent antagonist of sphingosine-1-phosphate (S1P) receptors, with selectivity for S1P₁ and S1P₃ subtypes. By blocking receptor-mediated signaling, it disrupts S1P-driven pathways that regulate lymphocyte trafficking, vascular tone, and cell survival. This compound is commonly used in research to investigate immune modulation, cardiovascular function, and cancer biology. Through selective inhibition, VPC 23019 provides insights into the roles of S1P receptors in inflammation, autoimmune disease, and tumor progression, making it a valuable pharmacological tool in disease mechanism studies.
