Compounds of Formula (I) are described; wherein R1 is a heteroaryl or heterocyclic group, optionally substituted for one or a plurality of atoms or groups; X is 1 to 4 substituents, identical or different from each other and selected from halogen, (C1-C10) alkyl, (C1-C10) haloalkyl, (C1-C10) alkoxy, NRaRb, cyano, or nitro, (C1-C10) alkyl capable of being optionally substituted for one or a plurality of groups selected from halogen, (C1-C10) alkoxy, halogen (C1-C10) alkoxy, NRaRb, or hydroxyl; R, at positions 3, 5, 7, or 8 of Fimidazo [1,2-a] pyridine, is 1 to 4 substituents, identical or different from each other and selected from hydrogen, halogen, (C1-C10) alkyl ), (C1-C10) haloalkyl, or (C1-C10) alkoxy; R2 and R3, independently of each other, represent a hydrogen atom or an optionally substituted (C1-C10) alkyl group for an Rf group, or an optionally substituted aryl group; R4 is a hydrogen atom, an optionally substituted (C1-C10) alkyl group for an Rf group, or an optionally substituted aryl group as a base or salt having an added acid. The invention is used in therapy and synthetic methods. |
