Storage & Solubility Information
| Description | RS 42358-197 (RS 25259-007) is a competitive 5-HT3 receptor antagonist. |
| In vitro | RS 42358-197 acts against 5-HT-induced contractions in the guinea pig ileum (low-potency phase), yielding a pA2 estimate of 8.1[1]. |
| In vivo | In anesthetized rats. RS 42358-197, administered by the intravenous, intraduodenal or transdermal route, dose-dependently inhibited the Bezold-Jarisch reflex induced by 2-methyl 5-HT (ID50:0.05 micrograms/kg; i.v., 5.7 micrograms/kg; i.d., and 11.6 micrograms/chamber, respectively). In this regard, when administered intraduodenally, RS 42358-197 was more potent and exhibited a longer duration of action than either ondansetron or granisetron. In dogs, RS 42358-197, administered either intravenously or orally, dose-dependently inhibited the emesis induced by cisplatin, actinomycin and cyclophosphamide, but not that induced by apomorphine. When tested at maximally effective doses against cisplatin-induced emesis in dogs, RS 42358-197 had a longer duration of antiemetic activity (> 6 h) than ondansetron (2 h). RS 42358-197, administered orally, also afforded protection against cisplatin-induced emesis in ferrets. At doses that showed marked anti-emetic activity in dogs (10-100 micrograms/kg; i.v. and 100-1000 micrograms/kg; i.d.), RS 42358-197 did not produce any hemodynamic changes[1]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
