Fragment-Based Discovery of Type I Inhibitors of Maternal Embryonic Leucine Zipper Kinase
Acs Med.Chem.Lett., 6:25-, 2015

PubMed Abstract: Fragment-based drug design was successfully applied to maternal embryonic leucine zipper kinase (MELK). A low affinity (160 μM) fragment hit was identified, which bound to the hinge region with an atypical binding mode, and this was optimized using structure-based design into a low-nanomolar and cell-penetrant inhibitor, with a good selectivity profile, suitable for use as a chemical probe for elucidation of MELK biology.
