Qingyangshengenin B

SKU: orb1297629

Description

Qingyangshengenin B (Otophylloside B) is a C-21 steroidal glycoside with neuroprotective properties, notably reducing Aβ peptide expression and deposition. Research demonstrates its in vivo efficacy in extending lifespan and enhancing stress resistance in C. elegans AD models, alongside exhibiting antiepileptic activity in zebrafish seizure assays.

Bioactivity

• In Vitro:
  Otophylloside B (Ot B)?could modestly exten the lifespan of C. elegans, dela the age-related decline of body movement and improv the stress resistance. Further investigatin the molecular mechanism of lifespan extension effect revealed that Ot B could activat the FOXO transcription factor DAF-16.?Ot B could not further exten 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.
