The transcription inhibitor tetra-O-methyl nordihydroguaiaretic acid (M4N) was found to arrest the proliferation of C3, C33a, CEM-T4, and TC-1 cells in culture at the G2 stage of the cell cycle. Investigation into the mechanism of arrest revealed that M4N reduces mRNA levels and subsequent protein production of the cyclin-dependent kinase CDC2, resulting in the inactivation of the CDC2/cyclin B complex (maturation promoting factor). When injected intratumorally in a C3-cell induced C57b1/6 mouse tumor model system, M4N demonstrated substantial tumoricidal activity that correlated with a reduction in tumor cell CDC2 protein levels. These findings suggest that M4N may be a useful chemotherapeutic agent for the control of unregulated cellular proliferation.
