2OBJ: Crystal Structure of Human Pim-1 Kinase in Complex With Inhibitor

Citation:
Abstract
A novel series of highly potent substituted pyridone Pim-1 kinase inhibitors is described. Structural requirements for in vitro activity are outlined as well as a complex crystal structure with the most potent Pim-1 inhibitor reported (IC(50)=50 nM). A hydrogen bond matrix involving the Pim-1 inhibitor, two water molecules, and the catalytic core, together with a potential weak hydrogen bond between an aromatic hydrogen on the R(1) phenyl ring and a main-chain carbonyl of Pim-1, accounts for the overall potency of this inhibitor.
