PD184161 is an orally active MEK inhibitor. PD184161 inhibits MEK activity (IC50=10-100 nM) in a time- and concentration-dependent manner. PD184161 inhibits cell proliferation and induces apoptosis. PD184161 produces depressive-like behavior.

体外研究(In Vitro)
PD184161 (1-20 μM; 24, 48, or 72 hours) inhibits cell proliferation and induces apoptosis in a time and concentration dependent manner.
PD184161 (0.1 and 1.0 μM; 1 hour) inhibits ERK1,2 phosphorylation.
PD184161 (5 μM; 30 min) prevents the toxic effects of bicuculline.
