产品描述 | SLF1081851 is aSpns2inhibitor, inhibitsS1Prelease (IC50=1.93 μM). SLF1081851 plays a key role in development and immune system[1][2]. 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 IC50value 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].
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: | C57BL/6 mice[1] | Dosage: | 20 mg/kg | Administration: | Intraperitoneal injection; blood was drawn 4 h postdose | Result: | Significantly decreased circulating lymphocyte count and plasma S1P concentration. |
Animal Model: | SpragueDawley mice (4-week-old)[1] | Dosage: | 10 mg/kg | Administration: | Intraperitoneal injection; single dose; measured at 0, 0.5, 1, 2, 4, 6, and 24 h postdose | Result: | Reached a maximum concentration of 5 μM in blood at 2 h with drug levels sustained at ≥ 2 μM for at least 24 h, proved a half-life of over 8 h in rats. The appearance of SPNS2-IN-1 in circulation correlated with a maximal decrease in lymphocyte count at 4 h (25% lower compared to time =0). |
