Description

Casopitant mesylate (GW679769B) is a selective, brain permeable, and orally active antagonist of neurokinin 1 (NK1) receptor. It is a second in the class of antiemetics.

In vivo

In a ferret-model of Cisplatin-induced emesis, Casopitant inhibits retching and vomiting and reduced nausea-like behaviours in a dose-dependent manner. Following a single intraperitoneal dose, radioactive labeled Casopitant ([14C]Casopitant) is rapidly absorbed, with plasma and brain concentrations being approximately equal at two hours post-dosing. [14C]Casopitant is found in the brain as the parent compound and two major oxidative metabolites (M1 and M2), accounting for approximately 76%, 19%, and 3% of the radioactivity, respectively. Casopitant possesses a high affinity for brain NK1 receptors in the ferret [2].

The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
