Abstract: The present invention relates to an aminosquaramide polymer comprising a backbone of repeating structural units, being these repeating structural units equal or different and selected from the group consisting of: monomer of formula (A) (or a salt thereof), and monomer of formula (B) (or a salt thereof); and a conjugate comprising the aminosquaramide polymer and one or more molecules of interest. It also refers to compositions containing the polymer or the conjugate; and processes for their preparation, as well as their uses as a carrier, in therapy, in diagnostic, in cosmetic and as a transfecting agent.

Abstract: Use of squaramide-based macrocylic compounds as kinase inhibitor agents and as anti-tumour agents. More specifically, said compounds are used to treat diseases such as cancer, diabetes, neurodegenerative diseases, HIV replication, etc.
