The present invention provides novel imidazo[1,2-a]pyridine compounds that are useful in therapy of diseases and disorders. The novel compounds inhibit the activation of Hypoxia Inducible Factor (HIF)-mediated transcription and signaling under hypoxic conditions. In one aspect, the compounds of the present invention are useful for the preparation of a medicament for the treatment or prevention of a disease or disorder selected from the group consisting of an inflammatory disease, a hyperproliferative disease or disorder, a hypoxia-related pathology and a disease characterized by excessive vascularization. Also provided is a pharmaceutical composition, comprising a compound of the invention and a second therapeutic agent or radiation, useful for the treatment or prevention of the mentioned diseases or disorders, wherein X is CH 2 , CH 2 CH 2 or C═O; R 1 is phenyl or C-bound monocyclic 5- or 6-membered heteroaryl, wherein phenyl and monocyclic 5- or 6-membered heteroaryl are unsubstituted or carry 1, 2, 3, 4 or 5 radicals R 1a which are identical or different; R 2 is phenyl or C-bound monocyclic 5- or 6-membered heteroaryl, wherein phenyl and monocyclic 5- or 6-membered heteroaryl are unsubstituted or carry 1, 2, 3, 4 or 5 radicals R 2a which are identical or different; R 3 is hydrogen, C 1 -C 6 -alkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl, fluorinated C 1 -C 2 -alkyl C(O)R 4 ; where R 1a , R 2a and R 4 are as defined in the claims and the specification. |
