Abstract:
Following the discovery of imidazopyridine 1 as a potent IGF-1R tyrosine kinase inhibitor, the aniline part has been modified with the aim to optimize the properties of this series. The structure-activity relationships against IGF-1R kinase activity as well as inhibition of the hERG ion channel are discussed.
