1. Dehydrocorydaline (13-Methylpalmatine) exerts anti-metastatic potential via suppression of MMPs and Bcl-2 signaling in NSC-LC cells. 2. Dehydrocorydaline stimulates p38 MAPK activation, which can enhance heterodimerization of MyoD and E proteins, thus resulting in MyoD activation and myoblast differentiation. 3. Dehydrocorydaline shows antiplatelet effects, it inhibits thrombin-induced platelet aggregation in a low dose ( IC50= 34.914 ug/mL). 4. Dehydrocorydaline has anti-inflammatory and antinociceptive effects. 5. Dehydrocorydaline inhibits MCF-7 cell proliferation by inducing apoptosis mediated by regulating Bax/Bcl-2, activating caspases as well as cleaving PARP.
