生物活性

Gypenoside L is a saponin that can be found in Gynostemma pentaphyllum. Gypenoside L increases the SA-β-galactosidase activity, promotes the production of senescence-associated secretory cytokines. Gypenoside L also can activate p38 and ERK MAPK pathways and NF-κB pathway to induce senescence. Gypenoside L exhibits anti-tumor and anti-inflammatory activities[1][2].

体外研究
(In Vitro)

Gypenoside L (20-80 μg/mL; 24 h) increases the mRNA expression levels of SASP, such as IL-1α, IL-6, TIMP-1, CXCL-1 and CXCL-2 in HepG2 and ECA-109 cells[1].
Gypenoside L (20-80 μg/mL; 24 h) causes cell cycle arrest at S phase[1].
GPL (3.125-100 μg/mL) significantly inhibits LPS-induced NO accumulation in RAW264.7 cells[2].
