Gymnemic acid I

Gymnemic acid I is a bioactive triterpene saponin found in Gymnema sylvestre. Gymnemic acid I is an antisweetness inhibitor via human sweet receptor type 1 receptor 2 (T1R2) and T1R3. Gymnemic acid I is a ribosomal protein biosynthesis inhibitor. Gymnemic acid I has antidiabetic effects. Gymnema acid I induces autophagy-protected MIN-6 cells from apoptosis under high glucose stress by inhibiting the phosphorylation activity of mTOR[1][2].
