Description
Gymnemic acid I is a triterpene glycoside that has been found in
G. sylvestre and has antihyperglycemic activities. It inhibits glucose-induced phosphorylation of serine 70 on S6 kinase (S6K1) and serine 2448 on mTOR, caspase-3 activity, and apoptosis, as well as increases autophagy in MIN-6 pancreatic β cells when used at a concentration of 5 μg/ml. Gymnemic acid I has been used as a reference compound to compare the potency of plant-derived sweet taste inhibitors.
Uses
(+)-Gymnemic Acid I is one of the components extracted from the leaves of Gymnema sylvestre, known for inhibitory acitivity against glucose absorption. However, (+)-Gymnemic Acid I lacks this activity, unlike other forms of gymnemic acids.
