The invention relates to novel heterocyclic compounds which are pyrazolopyridine derivatives that induce fibroblast growth factor receptor (FGFR) dimerization, having the general formula: M1-L-M2 in which M1 or 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: Process for the preparation thereof and therapeutic use thereof.
