Isocorydine induces G2/M phase arrest by increasing cyclin B1 and p-CDK1 expression levels, which was caused by decreasing the expression and inhibiting the activation of Cdc25C. The phosphorylation levels of Chk1 and Chk2 were increased after ICD treatment. Furthermore, G2/M arrest induced by ICD can be disrupted by Chk1 siRNA but not by Chk2 siRNA. In addition, isocorydine treatment led to a decrease in the percentage of CD133+ PLC/PRF/5 cells. Interestingly, isocorydine treatment dramatically decreased the tumorigenicity of SMMC-7721 and Huh7 cells. (A15211)
説明Isocorydine is an aporphine alkaloid that has been found in A. squamosa that has vasodilatory and anticancer activities. It reduces the action potential duration and increases the effective refractory period in isolated canine Purkinje fibers when used at a concentration of 30 μM. Isocorydine induces relaxation of norepinephrine-precontracted isolated rabbit aortic strips with an EC50 value of 12.6 μM. It is cytotoxic to A549 lung cancer cells (IC50 = 197.7 μM), as well as Huh7, HepG2, SNU-449, and SNU-387 hepatic cancer cells (IC50s = 161.3, 148, 262.2, and 254.1 μg/ml, respectively). Isocorydine, in combination with doxorubicin, reduces tumor growth in a Huh7 mouse xenograft model.
