    摘要: The present invention describes the new use in the oncologic field of bioconjugates as differentiating agents obtained by the conjugation between hyaluronic acid (HA) and a chemotherapeutic product (identified hereafter with the trade-name ONCOFID®) among which, in particular, Irinotecan, Doxorubicin, Paclitaxel, Cis-platinum and 5-Fluorouracyl (5-FU) for treating primary tumors and metastasis. In particular, the biological behaviour is described in terms of action mechanism, efficacy and tolerability of pharmaceutical preparations of derivative of ONCOFID® soluble in water. More specifically, the invention relates to the surprising biological and pharmacological effect demonstrated by formulations based on ONCOFID-S (HA-SN38 conjugates) and ONCOFID-D (HA-Doxorubicin conjugates) in promoting the differentiation of tumoral cells towards a untransformed phenotype, compared with the reference drug Irinotecan (or CPT11 whose active form is represented by SN38) and Doxorubicin.

    摘要: The present invention describes a new class of cross-linked derivatives of partially N-deacetylated hyaluronic acid or derivatives thereof, comprising at least one repeating unit of formula (I) hereinafter depicted and a process for the preparation of said cross-linked derivatives, comprising a multicomponent condensation reaction involving the carboxy groups and the amino groups originating from a partial N-deacetylation of hyaluronic acid or derivatives, together with an aldeyde and an isocyanide. The derivatives thus obtained can be used, alone or in association with biologically and/or pharmacologically active substances, for the preparation of pharmaceutical compositions, biomaterials, surgical and healthcare articles, slow release systems and for the coating of biomedical objects.

    摘要: The present invention relates to a process for the synthesis of conjugates of glycosaminoglycanes (GAG) with biologically active molecules of varying nature, comprising small molecules and macro-molecules. In particular, the present invention relates to the conjugation of hyaluronic acid (HA) and its derivatives with polypeptides and proteins with a biological action, such as, for example, interferons, erythropoietins, growth factors, insulin, cytokines, antibodies and hormones.An object of the present invention also relates to isolatable intermediates obtained by the partial or total reaction of GAG with protected amino aldehydes in the conjugation process mentioned above.
