 Use of Corynoxine B


Corynoxine B is an oxindole alkaloid isolated from Uncaria rhynchophylla (Miq.) Jacks (Gouteng in Chinese); a Beclin-1-dependent autophagy inducer. IC50 value:Target: Autophagy inducerin vitro: Corynoxine B, a natural autophagy inducer, restores the deficient cytosolic translocation of HMGB1 and autophagy in cells overexpressing SNCA, which may be attributed to its ability to block SNCA-HMGB1 interaction [1].in vivo: Corynoxine B exhibited prolongation of the thiopental-induced hypnosis on oral administration in mice [2].
