    We report structure-guided modifications of the benzyloxy substituent of the Insulin-like Growth Factor-1 Receptor (IGF-1R) inhibitor NVP-AEW541. This chemical group has been shown to confer selectivity against other protein kinases but at the expense of a metabolism liability. X-ray crystallography has revealed that the benzyloxy moiety interacts with a lysine cation of the IGF-1R kinase domain via its ether function and its aromatic π-system and is nicely embedded in an induced hydrophobic pocket. We show that 1,4-diethers displaying an adequate hydrophobic and constrained shape are advantageous benzyloxy replacements. A single digit nanomolar inhibitor (compound 20, IC50=8.9 nM) was identified following this approach.
