PF-543 (Citrate) Chemical Properties,Usage,Production

Uses

PF-543 Citrate (Sphingosine Kinase 1 Inhibitor II Citrate) is a potent, selective, reversible and sphingosine-competitive SPHK1 inhibitor with an IC50 of 2 nM and a Ki of 3.6 nM. PF-543 Citrate is >100-fold selectivity for SPHK1 over SPHK2. PF-543 Citrate is an effective potent inhibitor of sphingosine 1-phosphate (S1P) formation in whole blood with an IC50 of 26.7 nM. PF-543 Citrate induces apoptosis, necrosis, and autophagy[1][2][3].

in vivo

PF-543 (1 mg/kg; intraperitoneal injection; every second day; for 21 days; female C57BL/6 J mice) treatment has no effect on vascular remodelling but reduces right ventricular hypertrophy. The protection involves a reduction in the expression of p53 and an increase in the expression of anti-oxidant nuclear factor Nrf-2^[2].
? Mice are initially dosed (ip) with 10 mg/kg or 30 mg/kg of PF-543 for 24 h and the T_1/2 is 1.2 h in blood samples. Administration of 10 mg/kg PF-543 for 24 h to mice induces a decrease in SK1 expression in pulmonary vessels^[2].

Animal Model:	Female C57BL/6 J mice (7-12 week-old) with hypoxic-induced pulmonary arterial hypertension^[2]
Dosage:	1 mg/kg
Administration:	Intraperitoneal injection; every second day; for 21 days
Result:	Reduced right ventricular hypertrophy. The protection involves a reduction in the expression of p53 (that promotes cardiomyocyte death) and an increase in the expression of anti-oxidant nuclear factor Nrf-2.
