PD 0325901 is an orally bioavailable, synthetic organic molecule targeting mitogen-activated protein kinase kinase (MAPK/ERK kinase or MEK) with potential antineoplastic activity. MEK inhibitor PD325901, a derivative of MEK inhibitor CI-1040, selectively binds to and inhibits MEK, which may result in the inhibition of the phosphorylation and activation of MAPK/ERK and the inhibition of tumor cell proliferation. Clinical trials of monotherapy PD0325901 agains non-small cell lung cancer and colorectal cancer did not reach efficacy end point. For subsequent studies KRAS-positive patients with non-small cell lung cancer and colorectal cancer were selected, and PD0325901 was evaluated in combination with pablociclib and dacomtinib. PD0325901 is evaluated in phase II clinical trials against neurofibromatosis.

Sample Use Guides
In clinical trials against KRAS-mutant NSCLC PD-0325901 was administered orally twice daily, 3 weeks out of every 4 in each cycle. The initial dose for phase 1 of the study was be 2 mg twice daily.
Route of Administration:
Oral
MTT assay was used to evaluate effect of PD-0325901 on tumor cell proliferation. Briefly, cells (800/well) were seeded into a 96-well plate, and after 5 days of treatment with the indicated concentrations of PD0325901, 10 μL of 5 mg/mL MTT (Sigma) was added to cell culture, followed by addition of 100 μL of 10% sodium dodecyl sulfate (SDS) solution 4 hours later. After incubation for another 12 hours, the plates were read on a microplate reader at a test wavelength of 570 nm and a reference wavelength of 670 nm. PD-0325901 demonstrated potent inhibition of cells harboring BRAF or RAS mutations (KAK1, KAT5, KAT7, KAT10, NPA, DRO, and C643) with IC50 ranging from 0.059 to 0.783 uM.
