IC50: 10-100 nM PD 184161 is a MEK1/2 inhibitor. The intracellular signaling pathway of mitogen-activated protein kinases is involved in the regulation of various cellular functions. One of these pathways, named Raf/MEK/ERK pathway, plays a key role in the regulation of cellular differentiation, growth, and proliferation. The modulation of this Raf/MEK/ERK pathway has been reported as a useful approach to treate proliferative disorders such as cancer. In vitro: Previous study found that PD184161 could inhibit MEK activity in a time- and concentration-dependent manner, which was more effectively than PD098059 or U0126. Moreover, PD184161 could inhibit cell proliferation and induce apoptosis at concentrations of > or = 1.0 μM time- and concentration-dependently . In vivo: Animal study showd that tumor xenograft P-ERK levels were significantly reduced 3 to 12 hours after an oral dose of PD184161. Contrarily, tumor xenograft P-ERK levels following long-term treatment of PD184161 were refractory to this signaling effect. PD184161 also significantly suppressed tumor engraftment and initial growth, however, established tumors were not significantly affected. In summary, PD184161 has antitumor effects in HCC in vivo that appear to correlate with suppression of MEK activity . Clinical trial: So far, no clinical study has been conducted.
