  • Publication number: 20180208600
    Abstract: The present invention relates to certain compounds (e.g., imidazopyrazine, imidazopyridine, imidazopyridazine and imidazpyrimidine compounds) that act as inhibitors of the MAP kinase interacting kinases MNK2a, MNK2b, MNK1a, and MNK1b. The present invention further relates to pharmaceutical compositions comprising these compounds, and to the use of the compounds for the preparation of a medicament for the prophylaxis and treatment of diseases (e.g., proliferative diseases (e.g., cancer), inflammatory diseases, Alzheimer's disease), as well as methods of treating these diseases.
