Ruthenium half-sandwich complexes bound to protein kinase Pim-1

(Figure Presented) Keeping in shape with half a sandwich: The structure of a picomolar organoruthenium inhibitor bound to the ATP-binding site of the protein kinase Pim-1 (see picture) demonstrates that the ruthenium center has solely a structural role in organizing the organic ligands in the three-dimensional receptor space, thus yielding a structure that is complementary in shape and functional group presentation to the active site of Pim-1. © 2006 Wiley-VCH Verlag GmbH & Co.
