SLF1081851_product_DataBase

Bioactivity	SLF1081851 is a Spns2 inhibitor, inhibits S1P release (IC50=1.93 μM). SLF1081851 plays a key role in development and immune system[1][2].
Target	Spns2 (spinster homologue 2)
Invitro	Sphingosine 1-phosphate (S1P) is a pleiotropic signaling molecule, and Spns2 exerts the functions to maintain lymph S1P[1].SLF1081851 (compound 16d) (0-5 μM; 18-20 h) inhibits S1P release with an IC50 value of 1.93 μM in Hela cells[1]. SLF1081851 (0-30 μM; 20 min) inhibits mSphK1 (recombinant mouse SphK) (10 μM) and mSphK2 (5 μM) in a dose-dependent manner and suggests at least 15-fold selectivity (SphK1 IC50≥30 μM; SphK2 IC50≈30 μM)[1].
In Vivo	SLF1081851 (20 mg/kg; i.p., 4 h postdose) significantly inhibits circulating lymphocytes and plasma S1P, and recapitulates the genetic phenotype of Spns2 null mice[1]. Animal Model:
