Biological Activity

Description Granisetron is a serotonin 5-HT3 receptor antagonist,used to treat chemotherapy-induced nausea and vomiting.
5-HT3 [1]
In vitro

Granisetron blocks the delayed rectifier current (IK) of feline isolated ventricular myocytes with a KD of 4.3 mM. Granisetron shows an intrinsic voltage-dependence as the block increases with depolarization. Granisetron blocks from the intracellular side at a binding site located 10% across the transmembrane electrical field. Granisetron (3 mM) prolongs the action potential duration (APD) by about 30% at 0.5 Hz in feline isolated ventricular myocytes. [1] Granisetron but not Ondansetron, could prevent the activation of putative 5-H; autoreceptors, thus leading to a decrease in serotonin release by the enterochromaffin cells. [2]

In vivo Granisetron provides a substantial benefit against cisplatin-induced emesis in the piglet, some animals being completely protected during both the acute and the delayed phases. [2] Granisetron (1 mg/kg, i.m.) administered three times per day reduces significantly the retching+vomiting response induced by cisplatin on days 1 and 2 by 100.0% and 75.0%, respectively, in cats. [3] Granisetron or dexamethasone significantly improves macroscopic and histologic scores, curtails myeloperoxidase activity and diminishes colonic levels of inflammatory cytokines and malondialdehyde in rats. [4] Granisetron, not only prevents cholera toxin-induced jejunal net fluid secretion but also, and in proportion, inhibits 5-HT release into the intestinal lumen of mice. [5]

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.
