Dehydrocorydaline (13-Methylpalmatine) is an alkaloid that regulates protein expression of Bax, Bcl-2; activates caspase-7, caspase-8, and inactivates PARP^[1]. Dehydrocorydaline elevates p38 MAPK activation. Anti-inflammatory and anti-cancer activities^[2]. Dehydrocorydaline shows strong anti-malarial effects (IC₅₀=38 nM), and low cytotoxicity (cell viability > 90%) using P. falciparum 3D7 strain^[3].

Dehydrocorydaline (0-200 μM) treatment significantly inhibits the growth of MCF-7 cells in a dose-dependent manner. The cell viability is decreased by approximate 40% after 24 h of 200 μM Dehydrocorydaline^[1].
Dehydrocorydaline (0-200 μM)dose-dependently increases Bax protein expression and decreases Bcl-2 protein expression^[1].
Dehydrocorydaline (0-200 μM)induces activation of caspase-7,-8 and the cleavage of PARP without affecting caspase-9^[1].

Dehydrocorydaline manifests a low acute toxicity with an LD₅₀ of about 277.5±19.0 mg/kg body weight in mice following oral administration and 21.1±1.4 mg/kg for intraperitoneal injection^[4].
