Catalog No. TMS1461Cas No. 106758-54-7
Alias Otophylloside B
Qingyangshengenin B (Otophylloside B) is a C-21 steroidal glycoside isolated from Qingyangshen. Qingyangshengenin B protects against Aβ toxicity, which decreases Aβ deposition by decreasing the expression of Aβ at the mRNA level. Qingyangshengenin B has antiepileptic and anti-aging effects, it can extend lifespan, increase heat stress-resistance, delay body paralysis, and increase the chemotaxis response in C. elegans models of Alzheimer's disease. Otophylloside B can suppress the seizure-like locomotor activity caused by pentylenetetrazole in zebrafish.

| In vitro | Otophylloside B (Ot B)?could modestly extend the lifespan of C. elegans, delay the age-related decline of body movement and improve the stress resistance.?Further investigating the molecular mechanism of lifespan extension effect revealed that Ot B could activate the FOXO transcription factor DAF-16.?Ot B could not further extend the lifespan of long-lived mutant of insulin/IGF-1-like receptor (daf-2).?In addition, Ot B also requires SIR-2.1 and CLK-1 which is an enzyme in ubiquinone synthesis, for lifespan extension. |

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.
