The invention relates to novel heterocyclic compounds which are pyrazolopyridine derivatives that induce FGFR dimerization, having the general formula: M-L-M2 in which M and M2, which may be identical or different, each represent, independently of one another, a monomer unit M and L represents a linker group which links M1 and M2 covalently with the monomer unit which follows (Formula M). Process for the preparation thereof and therapeutic use thereof.
