Description
MK-8745 is a potent and selective Aurora A inhibitor with IC50 of 0.6 nM, more than 450-fold selectivity for Aurora A over Aurora B.target: Aurora A, Aurora BIC50: 0.6 nM [1]MK-8745, a novel Aurora-A specifi c inhibitor, leads to cell cycle arrest at the G2/M phase with accumulation of tetraploid nuclei followed by cell death in non-Hodgkin lymphoma (NHL) cell lines[2]. MK8745 induced apoptotic cell death in a p53-dependent manner. Exposure of p53 wild-type cells to MK8745 resulted in the induction of p53 phosphorylation (ser15) and an increase in p53 protein expression.[1] MK-8745 can aff ect downstream targets of Aurora-A and induce apoptotic cell death.[2]
