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 mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
