The subject-matter of the present invention relates to the synthesis of new dendrimeric molecules based on polyhydroxylated pyrrolidines obtained by means of Click Chemistry reactions. The proposed molecules inhibit the enzymes N-acetylgalactosamine-6-sulfatase (GALNS), iduronate-2-sulfatase (IDS), a-mannosidase and β-glucosidase, deficient in lysosomal storage diseases. The presentation of multivalent iminosugars on a scaffold is a prerequisite for the inhibitory activity as the corresponding monomers are not active. The inhibitory activity reported is the basis for the development of the first-ASSC pharmacological chaperones proposed for the treatment of the above mentioned pathologies. Formula (I)
