Abstract
In our previous study, a novel phenylbutenoid dimer (±)-trans-3-(3, 4-dimethoxyphenyl)-4-[(E)-3,4-dimethoxystyryl] cyclohex-1-ene (PSC), isolated from Zingiber cassumunar ROXB. (Zingiberaceae), inhibited proliferation of various human cancer cells with the IC 50 values ranging 10 to 30 μM. Prompted by these anti-proliferative effects, we performed additional studies in A549 human lung cancer cells in order to investigate the mechanism of action. PSC arrested cell cycle progression at the G0/G1 phase in a concentration- and time-dependent manner. PSC dose-dependently induced cyclin-dependent kinase (CDK) inhibitor p21 expression, whereas the expression of cyclin D1, cyclin A, CDK4, CDK2, and proliferating cell nuclear antigen (PCNA) were decreased by treatment with PSC. These results suggest that one of the anti-proliferative mechanisms of PSC is to suppress cell cycle progression by increasing p21 expression and down-regulating cyclins and CDKs. This study characterizes additional biological activity of this novel phenylbutenoid dimer and expands its therapeutic potential for cancer as a chemotherapeutic agent derived from natural products. © 2007 Pharmaceutical Society of Japan.
