| Abstract: | The mitogen-activated protein kinase kinase 4 (MKK4) plays a key role in liver regeneration and is under investigation as a target for stimulating hepatocytes to increased proliferation. Therefore, new small molecules inhibiting MKK4 may represent a promising approach for treating acute and chronic liver diseases. Fluorescently labeled compounds are useful tools for high-throughput screenings of large compound libraries. Here we utilized the azaindole-based scaffold of FDA-approved BRAF inhibitor vemurafenib 1, which displays off-target activity on MKK4, as a starting point in our fluorescent compound design. Chemical variation of the scaffold and optimization led to a selection of fluorescent 5-TAMRA derivatives which possess high binding affinities on MKK4. Compound 45 represents a suitable tool compound for Fluorescence polarization assays to identify new small-molecule inhibitors of MKK4. |
