Sinapine is an alkaloid isolated from seeds of the cruciferous species. Sinapine exhibits anti-inflammatory, anti-oxidant, anti-tumor, anti-angiogenic and radio-protective effects. Sinapine is also an acetylcholinesterase (AChE) inhibitor and can be used for the research of Alzheimer’s disease, ataxia, myasthenia gravis, and Parkinson’s disease^[1][2][3][4].

AChE^[4], P-gp^[1]

Sinapine (6 or 60 μM; 1 h) counteracts H₂O₂ and antimycin A-induced mitochondrial oxidative stress in cardiomyocytes^[1].
Sinapine (10-200 μM; 24 h) inhibits the proliferation of Caco-2 cells in a dose-dependent manner, and has relatively low toxicity^[3].
Sinapine (10-200 μM; 24 h) promotes doxorubicin accumulation in Caco-2 cell by inducing P-glycoprotein (P-gp) decrease^[3].
Sinapine (10-200 μM; 24 h) significantly reduces phosphorylation of FRS2α, ERK1/2^[3].
