生物活性

JTE-013 is a potent and specific S1P2 (Sphingosine-1-Phosphate 2; EDG-5) antagonist. JTE-013 inhibits the specific binding of radiolabeled S1P to human and rat S1P2 with IC50s of 17 nM and 22 nM, respectively[1].

IC50 & Target

IC50: 17 nM (S1P2 for human) and 22 nM (S1P2 for rat)[1]

体外研究
(In Vitro)

JTE-013 (50-200 μM; 1-3 days) reduced cell viability[1].
JTE-013 (10-1000 nM; 30 mins) reverses S1P-induced Akt inhibition and inhibits S1P-induced ERK activation[1].
JTE-013 displays 4.2% inhibition of S1P3 and does not antagonize S1P1 at concentrations up to 10 μM[1].
