Inhibition or enhancement of the TPA-induced activation of AP-1 by methoxy-substituted trans-stilbenes. Screening with the 293/AP-1-luc cell of methoxy-substituted trans-stilbenes, which do not retain anti-oxidant activity, demonstrated that some derivatives inhibit, some enhance and others have no effects on the TPA-induced activation of AP-1. The * notation indicates p < 0.01.
