Biological target:
Corynoline is a reversible and noncompetitive acetylcholinesterase (AChE) inhibitor with an IC50 of 30.6 μM.
In vitro activity:
Treatment of melanoma cells with corynoline results in G2 cell arrest accompanied by reduced cdc2 activation. Furthermore, corynoline triggers apoptosis of melanoma cells, which is associated with increased expression of Bax and cleaved caspase-3. Reference: Phytother Res. 2020 Oct;34(10):2766-2777. https://pubmed.ncbi.nlm.nih.gov/32430958/
In vivo activity:
Therefore, the present study was intended to investigate the effect of Corynoline (COR) on CFA induced rheumatoid arthritis in a rat model. Results suggested that COR causes significant reduction in paw swelling, edema, arthritis score, thymus and spleen indexes and neutrophil infiltration (p < 0.01). Reference: Mol Cell Biochem. 2021 Feb;476(2):831-839. https://pubmed.ncbi.nlm.nih.gov/33174074/
