Biological Activity

Description Palonosetron (RS25259, RS 25259 197) is a 5-HT3 antagonist with Ki value of 0.17 nM. It is used in the prevention and treatment of chemotherapy-induced nausea and vomiting (CINV).
Targets
5-HT3 receptor [2]
0.17 nM(Ki)
In vitro
In vitro

Palonosetron is a 5-HT3 receptor antagonist with a high binding affinity for this receptor and little or no affinity for other receptors[1].
In Vivo
In vivo

Palonosetron has a longer half-life and a higher binding affinity than the first-generation 5-HT3 receptor antagonists. After intravenous dosing of palonosetron in healthy subjects and cancer patients, an initial decline in plasma concentration is followed by a slow elimination from the body. Mean maximum plasma concentration and area under the concentration-time curves are generally dose-proportional over the dose range of 0.3 to 90 μg/kg in healthy subjects and in cancer patients. Palonosetron has a volume of distribution of approximately 8.3 ± 2.5 L/kg and is 62% bound to plasma proteins. It is eliminated from the body through renal excretion and metabolic pathways. The mean terminal elimination half-life is approximately 40 hours[1].

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.
