Background

BI 847325 is a dual inhibitor of Ras-mitogen-activated protein kinase kinases (MEK) and Aurora kinases [1,2]. BI 847325 inhibits MEK1 and MEK2 with IC50 values of 25 and 4 nM, respectively. For inhibiting the activity of Aurora A, B and C, IC50 values are 3, 25 and 15 nM, respectively [1].

The RAS-dependent MAP kinase signaling pathway is important in the regulation of cell survival and proliferation. It is hard to design direct inhibitors of RAS proteins. MEK is a downstream kinase of MAP kinase [1]. MEK is a ERK kinase [3].

In cells treated with BI 847325, based on levels of phospho-histone H3 (pHH3) and phospho-ERK (pERK), EC50 values were determined. To KRAS-and-PI3Kα-mutant NCI-H460 cells, the EC50 value was 44 nM. To BRAF-mutant A375 cells, the EC50 value was 37 nM. In a panel of 240 cell lines from diverse tissues with diverse genetic background, BI 847325 produced a potent inhibition of cell proliferation with a gm GI50 value of 28 nM. In a subset of cell lines, BI 847325 induced cell death. These in vitro potency correlated with mutations in BRAF or RAS, significantly [1].

In nude mouse xenograft models of cutaneous melanoma (A375, mutant BRAF) and NSCLC (Calu-6, mutant KRAS), BI 847325 at a daily oral dose of 10 mg/kg produced complete inhibition of tumor growth. In animals with A375 tumors, treatment with BI 847325 significantly reduced levels of both pHH3 and pERK in the tumors compared to controls [1].
