Product Description

Triflusal (formerly UR1501; Disgren, Grendis, Aflen, Triflux), a platelet aggregation inhibitor and a salicylate analog, acts by irreversibly inhibiting the production of thromboxane-B2 in platelets via acetylating the enzyme COX-1/cycloxygenase-1. The main metabolite of Triflusal is HTB, which preserves 6-keto-PGF1α synthesis in porcine aortic endothelial cells (PAEC) cells without a significant decline for up to 24 h even at the higher concentration. Triflusal at 10 mM, 100 mM and 1 M decreases LDH efflux in rat brain slices after anoxia/reoxygenation by 24%, 35% and 49% respectively. Triflusal also reduces inducible NO synthase activity by 18%, 21% and 30%.

Biological Activity I Assay Protocols (From Reference)

ln Vitro

In vitro activity: The main Triflusal metabolite, HTB, preserves 6-keto-PGF1α synthesis in porcine aortic endothelial cells (PAEC) cells without a significant decline for up to 24 h even at the higher concentration. Triflusal at 10 mM, 100 mM and 1 M decreases LDH efflux in rat brain slices after anoxia/reoxygenation by 24%, 35% and 49% respectively. Triflusal also reduces inducible NO synthase activity by 18%, 21% and 30%.

ln Vivo

Triflusal (10 mg/kg i.v.) reduces platelet deposition on subendothelium-induced primary thrombus by about 68% in rabbits. Triflusal (10 mg/kg i.v.) reduces platelet deposition on a fresh thrombus formed over tunica media by about 48% in rabbits. Triflusal (40 mg/kg p.o.) reduces platelet deposition on a primary thrombus triggered by subendothelium and tunica media by 53% in rabbits. Triflusal (40 mg/kg p.o.) significantly reduces Cox-2 mRNA levels and protein levels without influence Cox-1 mRNA levels on the vascular wall in rabbits. Triflusal (600 mg/day for 5 days) results in an increase in NO production by neutrophils and an increase in endothelial nitric oxide synthase (eNOS) protein expression in neutrophils in healthy volunteers. Triflusal (300 mg, twice-daily orally) shows a more important increase in total walking distance and in pain-free walking distance over the basal values than those treated with placebo, together with an improvement of the symptomatology correlated with claudication in patients with chronic peripheral arteriopathy. Triflusal (300 mg, twice-daily orally) shows an increase in the peak-flow recorded through strain-gauge plethysmography in patients with chronic peripheral arteriopathy. Triflusal (30 mg/kg) strongly decreases iNOS immunolabeling at both survival times analyzed, attenuating iNOS immunoreactivity in astroglial cells and infiltrated neutrophils in rats. Triflusal (30 mg/kg) decreases neuronal and microglial COX-2 expression at 10 and 24 hours after lesion and microglial and astroglial expression of IL-1beta and TNF-alpha at 24 hours after lesion in rats.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

Calculate the Mass of a compound required to prepare a solution of known volume and concentration
Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:

Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
Enter 25 into the Concentration (End) box and select the correct unit (mM)
Enter 25 into the Volume (End) box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
