Description

Palonosetron HCl (RS 25259, RS 25259 197) is a 5-HT3 antagonist used in the prevention and treatment of chemotherapy-induced nausea and vomiting.

Targets

5-HT3 ^[1]

In vitro
In vitro	Palonosetron is a highly potent, selective, second-generation 5-HT3 receptor antagonist with a 5-HT3 receptor binding affinity that is ∼100-fold higher than other 5-HT3 receptor antagonists (pKi 10.5 compared with 8.91 for granisetron, 8.81 for tropisetron, 8.39 for ondansetron, 7.6 for dolasetron). Palonosetron also has an extended plasma elimination half-life of ∼40 h, significantly longer than others in its class (ondansetron, 4 h; tropisetron, 7.3 h; dolasetron, 7.5 h; ranisetron, 8.9 h).

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.
