Gypenoside LVI
Gypenoside LVI is an orally active dammarane-type triterpenoid compound found in Gynostemma pentaphyllum. Gypenoside LVI inhibits ERK and JNK phosphorylation, the NLRP3 inflammasome, and modulates M1 to M2 microglial polarization. Gypenoside LVI downregulates PCSK9 expression through a SREBP-independent pathway. Gypenoside LVI promotes cholesterol efflux via ABCG1 and SRB1, upregulates LXRα-mediated reverse cholesterol transport, and attenuates foam cell formation by reducing lipid accumulation and cholesterol uptake. Gypenoside LVI inhibits IL-6 and IL-1β secretion, reduces oxidative stress, neuroinflammation, microglial and astrocyte activation, and inhibits LPS-induced microglial proliferation. Gypenoside LVI can be used for research on atherosclerosis, hypercholesterolemia, depression, and non-small cell lung cancer.
