PF-543 Citrate Sphingosine Kinase 1 Inhibitor II Citrate

产品介绍

PF-543 Citrate (Sphingosine Kinase 1 Inhibitor II Citrate) 是一种有效，选择性，可逆和鞘氨醇竞争性 SPHK1 抑制剂，IC₅₀ 为 2 nM，K_i 为 3.6 nM。PF-543 Citrate 对 SPHK1 的选择性是 SPHK2 的 100 倍以上。PF-543 Citrate 还是有效的全血中 1-磷酸鞘氨醇 (S1P) 形成的有效抑制剂，IC₅₀ 为 26.7 nM。PF-543 Citrate 诱导细胞凋亡，坏死和自噬。

生物活性

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 K_i 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.

体外研究

PF-543 (10-1000 nM; 24 hours; PASM cells) treatment abolishes SK1 expression at nM concentrations.
PF-543 (0.1-10 μM; 24 hours; PASM cells) treatment induces caspase-3/7 activity.
PF-543 inhibits C₁₇-S1P formation in 1483 cells with an IC₅₀ of 1.0 nM.
SphK1 inhibition by PF-543 causes a dose-dependent depletion of the intracellular level of S1P with EC₅₀ concentration of 8.4 nM and a concomitant elevation of the intracellular level of sphingosine in 1483 cells. The level of endogenous S1P in 1483 cells after a 1 h treatment with 200 nM PF-543 is decreased 10-fold, producing a proportional increase in the level of sphingosine.

体内研究
(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.
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.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Female C57BL/6 J mice (7-12 week-old) with hypoxic-induced pulmonary arterial hypertension
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.
