Taste Receptor Inhibitor

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.

6-Methoxyflavanone (6-MeOF) is a flavonoid compound that can cross the blood-brain barrier. 6-Methoxyflavanone is a positive allosteric modulator of GABA_A receptors. 6-Methoxyflavanone exhibits positive allosteric regulatory effects on human recombinant α1β2γ2L and α2β2γ2L GABA_A receptors, and is relatively inactive on the α1β2 GABA_A receptor. 6-Methoxyflavanone showes inhibitory behavior towards the activation of bitter receptor hTAS2R39 and hTAS2R14, demonstrating a reversible and non-overcome antagonistic effect. 6-Methoxyflavanone has the effects of anti-anxiety, analgesia and relief of neuropathic pain.
