Synonyms: Natural heparin pentasaccharide Sodium, Fondaparin sodium, SR-90107A

Fondaparinux Sodium (Org 31540, Natural heparin pentasaccharide, Fondaparin, SR-90107A) is a synthetic glucopyranoside with antithrombotic activity. It selectively binds to antithrombin III, thereby potentiating the innate neutralization of activated factor X (Factor Xa) by antithrombin; a synthetic inhibitor of Factor Xa.

Biological Activity

Description Fondaparinux Sodium (Org 31540, Natural heparin pentasaccharide, Fondaparin, SR-90107A) is a synthetic glucopyranoside with antithrombotic activity. It selectively binds to antithrombin III, thereby potentiating the innate neutralization of activated factor X (Factor Xa) by antithrombin; a synthetic inhibitor of Factor Xa.
Targets
Factor Xa [1]
In vitro
In vitro Fondaparinux is a synthetic pentasaccharide that selectively inhibits factor Xa (FXa) in the coagulation cascade. Fondaparinux has been shown to inhibit the TF-FVIIa complex and FIXa in vitro[1].
Cell Research Cell lines U937 cells
Concentrations 0-100 μg/ml
Incubation Time 30 min
Method

Fondaparinux was diluted in PBS to a total volume of 50 μL and added to the wells. Labeled U937 cells (50 μL) were then added and incubated at room temperature for 30 min. Finally, the wells were washed three times with PBS and cells were lyzed using 2% Triton X-100 in 0.1 mol/L Tris-HCl pH 9.5.
In Vivo
In vivo Fondaparinux reduces kidney I/R injury primarily by inhibiting the recruitment of neutrophil. It dramatically reduced fibrin deposition in the kidney[1]. Fondaparinux can promote the stability of atherosclerotic lesions in apolipoprotein E-deficient mice, possibly through inhibiting expression of the inflammatory mediators in plaque and reduced synthesis of MMP-9 and MMP-13[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
