18α-Glycyrrhetinic acid

18α-Glycyrrhetinic acid, a diet-derived compound, is an inhibitor of NF-kB and an activator of proteasome, which serves as pro-longevity and anti-aggregation factor in a multicellular organism. 18α-Glycyrrhetinic acid induces apoptosis.

How to use

In Vitro:

18α-Glycyrrhetinic acid (18a-GA) markedly reduces LX-2 cell numbers by 14.8% and 31.2% after 48 h and 72 h of treatment, respectively (P< 0.05). 18α-Glycyrrhetinic acid also significantly increases the percentage of LX-2 cells in phase G0/G1 and decreases it in phase S after treated for 48 h and 72 h compare with the control group. 18α-Glycyrrhetinic acid increases apoptosis to 6.8% at 48 h, compare with control (2.5%), and at 72 h the percentages of apoptotic cells in control and the treatment groups are 3.1% and 15.6%, respectively, in LX-2 cells (P<0.01). Furthermore, 18α-Glycyrrhetinic acid induces expression of PPAR-γ and alters some cell cycle and apoptosis-related proteins. 18α-Glycyrrhetinic acid also inhibits NF-κB DNA-binding activity.

In Vivo:

18α-Glycyrrhetinic acid (18α-GA) treatment significantly enhances life span of C. elegans strains with the most effective concentration being 20 μg/mL. Results reveal a significant delay of paralysis upon 18α-Glycyrrhetinic acid treatment. 18α-Glycyrrhetinic acid treatment also confers a significant reduction of Aβ deposits.
