Description

General description

A cell permeable diaminopyrimidine derived compound that acts as a highly potent and selective inhibitor of Aurora A (IC₅₀ = 48 nM). Acts by binding to the hinge region via a pyrazole moiety and stabilizes a DFG-in, inactive conformation of Aurora A. Potentiates the loss of the wild-type MYCN protein by disrupting MYCN-Aurora A complex and allowing its ubiquitination and proteasomal degradation in MYCN-amplified SK-N-BE (2) and Kelly neuroblastoma cells (EC₅₀ = 223 and 146.7 nM, respectively). Causes a loss of S-phase entry of cells and allows their accumulation in both G0/G1 and G2 phases. Shown to be effective in vivo with serum t1/2 = 1.5 h in mice.
