体外研究 | Corynoxine (6.25-25 μM; 6-12 h) increases the expression of LC3-II, an autophagy specific marker, in N2a and SH-SY5Y cells in a dose-dependent manner. Corynoxine (25 μM; 48 h) promotes the degradation of wild type (WT) and mutant (A53T) α-syn in inducible PC12 cells via autophagy induction. Western Blot Analysis Cell Line: N2a and SH-SY5Y cells Concentration: 6.25, 12.5, 25 μM Incubation Time: 6, 12 hours Result: Induced autophagy in neuronal cell lines. |
体内研究 | Corynoxine (100-100 mg/kg; oral gavage) exhibits prolongation of the thiopental-induced hypnosis in mice. Corynoxine (10-100 μM for 12 h) induces autophagy in drosophila. |
