Chemical Name:1-[1,3-Dimethyl-4-(2-methylethyl)-1H-pyrazolo[3,4-b]pyr
idin-6-yl]-4-(3,5-dichloro-4-pyridinyl)-semicarbazide
Biological Activity:
Sphingosine-1-phosphate (S1P) receptor antagonist, highly
selective for S1P2 (EDG-5). Inhibits S1P binding to human S1P2
receptors with an IC50 value of 17.6 nM. At concentrations up to 10 μM, displays 4.2% inhibition of S1P3 and does not
antagonise S1P1. Enhances S1P-induced angiogenesis in vivo.
