BI-847325 Usage And Synthesis

Description

BI-847325 is a selective dual MEK/Aurora kinase inhibitor with IC₅₀ values of 3, 25, 15, 25, and 4 nM for X. laevis Aurora B, human Aurora A and Aurora C, and human MEK1 and MEK2, respectively. It can inhibit the growth and survival of both treatment-naive and drug-resistant melanoma cell lines, decreasing the expression of MEK and Mcl-1 while increasing the expression of pro-apoptotic protein Bim. At 70 mg/kg, BI-847325 induces apoptosis in treatment-naive and drug-resistant xenografted melanoma in vivo.

Uses

BI-847325 is a novel ATP-competitive MEK and Aurora kinase inhibitor. It can inhibit the growth of BRAF resistant melanoma cells through suppression of Mcl-1 and MEK expression in human melanoma cell lines and mouse xenograft model. The efficacy of BI-847325 was studied in patients with refractory solid tumors.

in vivo

IC 50

MEK2: 4 nM (IC₅₀); Aurora C: 15 nM (IC₅₀)
