(S)-phosphoric acid Mono-[3-(4-benzyloxy-phenyl)-2-octadec-9-enoylaMino-propyl] ester (aMMoniuM salt)

VPC 12249 has been used as lysophosphatidic acid (LPA)_1/3 receptor antagonist in various experimental studies.

VPC 12249 is an N-acyl (oleoyl) serine phosphate-based compound.

Lysophosphatidic acids (LPAs) are bioactive lipid mediators. It interacts with at least six specific LPA receptors (LPA1-6) to mediate extracellular signaling pathway. LPA and its receptors (LPA1-3) are implicated in the pathogenesis of radiation pneumonitis (RP). VPC 12249 (S) inhibits the binding ofLPA to LPA1 and LPA3 receptor.
