Biological Activity

Description Fosaprepitant dimeglumine salt (MK-0517) is a water-soluble phosphoryl prodrug for Aprepitant which is a NK1 antagonist.
Targets
NK-1 receptor [1]
In vitro
In vitro Fosaprepitant (MK-0517, L-758,298) is a phosphoryl prodrug for aprepitant. Aprepitant is a selective substance P (NK-1 receptor) antagonist approved as part of combination therapy with a corticosteroid and a 5-HT 3 receptor antagonist for the prevention of acute and delayed Chemotherapy-induced nausea and vomiting. [1]
In Vivo
In vivo Fosaprepitant is converted to aprepitant within 30 min after intravenous administration via the action of ubiquitous phosphatases when administered intravenously. Fosaprepitant is well tolerated up to 150 mg (1 mg/ml), and Fosaprepitant 115 mg is bioequivalent in its AUC to aprepitant 125 mg. Fosaprepitant 115 mg has been submitted for FDA approval as an alternative on day 1 of a 3-day oral aprepitant regimen, with oral aprepitant administered on days 2 and 3. [1]

Working concentration: mg/ml;

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.
