| Targets&IC50 | S1P:26.7 nM, SPHK1:2 nM, SPHK1:3.6 nM (Ki) |
| In vitro | PF-543 Citrate is a selective sphingosine competitive SPHK1 inhibitor with an IC50 of 2 nM and a Ki of 3.6 nM. PF-543 Citrate is also a potent inhibitor of sphingosine 1-phosphate (S1P) formation in whole blood with an IC50 of 26.7 nM. PF-543 Citrate inhibits the formation of C17-S1P in 1483 cells with IC50 of 1.0 nM. [1] |
| In vivo | Administration of PF-543 Citrate (1 mg/kg intrperitoneal injection every other day for 21 days) in a mouse hypoxic model of pulmonary hypertension had no effect on vascular remodeling but reduced right ventricular hypertrophy. PF-543 Citrate (10 mg/kg or 30 mg/kg intraperitoneally, 24h), T1/2 in mouse blood samples was 1.2 h. Administration of 10 mg/kg PF-543 Citrate to mice for 24 hours induced a decrease in SK1 expression in pulmonary vessels. [2] The inhibition of SPHK1 and S1PR2 activity by PF-543 Citrate significantly hindered pancreatic fibrosis in CP mice. [4] |
