Cycloastragenol(Cas 84605-18-5) Usage

Description

Cycloastragenol is a triterpenoid isolated from various legume species in the genus Astragalus that is purported to have telomerase activation activity. TA-65 is capable to increase average telomere length and to decrease the percentage of critically short telomeres and DNA damage in MEFs that harbor critically short telomeres. The effects on telomerase appear to be in common with other triterpenoid saponins (ie, ginsenosides RG1 and Rg3). These compounds at concentrations from 1 to 20 μM were reported to protect against IL-1β-, H2O2-, and tert-butylhydroperoxide-induced senescence in human chondrocytes, endothelial progenitor cells and fibroblasts, respectively.

Uses

Cycloastragenol is an aglycone derivative of astragaloside IV found in the root of Korean Astragalus membranaceus.

Definition

ChEBI: A sapogenin that is the aglycone derivative of astragaloside IV, a major saponin extracted from the root of Astragalus membranaceus.
