Dehydrocorydaline chloride (13-Methylpalmatine chloride) is an alkaloid that regulates protein expression ofBax,Bcl-2; activatescaspase-7,caspase-8, and inactivatesPARP^[1]. Dehydrocorydaline chloride elevatesp38 MAPKactivation. Anti-inflammatory and anti-cancer activities^[2]. Dehydrocorydaline chloride shows strong anti-malarial effects (IC₅₀ =38 nM), and low cytotoxicity (cell viability > 90%) usingP. falciparum3D7 strain^[3].

Treatment of C2C12 myoblasts with 500 nM Dehydrocorydaline increases the expression levels of muscle-specific proteins, including MyoD, myogenin and myosin heavy chain. Treatment with Dehydrocorydaline elevates p38 MAPK activation and the interaction of MyoD with an E protein. Furthermore, defects in differentiation-induced p38 MAPK activation and myoblast differentiation induced by depletion of the promyogenic receptor protein Cdo in C2C12 myoblasts are restored by Dehydrocorydaline treatment^[2]. Dehydrocorydaline significantly inhibits MCF-7 cell proliferation in a dose- dependent manner, which can be reversed by a caspase-8 inhibitor, Z-IETD-FMK. Dehydrocorydaline increases DNA fragments without affecting ΔΨm. Western blotting assay shows that dehydrocorydaline dose-dependently increases Bax protein expression and decreases Bcl-2 protein expression. Furthermore, dehydrocorydaline induces activation of caspase-7,-8 and the cleavage of PARP without affecting caspase-9. These results show that dehydrocorydaline inhibits MCF-7 cell proliferation by inducing apoptosis mediated by regulating Bax/Bcl-2, activating caspases as well as cleaving PARP^[1].

Dehydrocorydaline (3.6, 6 or 10 mg/kg, i.p.) shows a dose-dependent antinociceptive effect in the acetic acid-induced writhing test and significantly attenuates the formalin-induced pain responses in mice. In the formalin test, dehydrocorydaline decreases the expression of caspase 6 (CASP6), TNF-α, IL-1β and IL-6 proteins in the spinal cord. These findings confirm that Dehydrocorydaline has antinociceptive effects in mice^[4].
