    摘要： The present invention relates to nanoparticles comprising a biodegradable polymer, preferably the vinyl methyl ether and maleic anhydride (PVM/MA) copolymer, and a polyethylene glycol or derivatives thereof. These nanoparticles are easy to produce and provide excellent bioadhesion, size and zeta potential characteristics making them suitable for the administration of active molecules. The selection of the type of polyethylene glycol used in their production allows suitably modulating the characteristics of these nanoparticles, which can be advantageously used according to the type of drug to be carried and/or the method of administration of the pharmaceutical formulation. pegylation is carried out by simple incubation for a short time period of the two macromolecules in question, without needing to have to resort to the use of organic solvents with high toxicity or long and laborious organic synthesis processes. Furthermore, the pegylation process can be associated to the process of encapsulating the biologically active molecule.

    摘要： A Method for the treatment of skin fibrosis with a peptide that inhibits TGF-β, and suitable compositions for its administration. The method includes in particular, the use of peptide P144, a compound that is a known inhibitor of TGF-β, for the treatment of skin fibrosis by topical application. The method is shown effective in an animal model of bleomycin-induced skin sclerosis, to a reduction both of the skin fibrosis and of the content of soluble collagen, without any signs of systemic toxicity being detected. This shows that P144 is effective for topical application in mammals for treating fibrotic skin diseases and pathological scarring of the skin. For the administration of this peptide, stable compositions are also supplied, with pleasant appearance without being greasy, with good spreading characteristics and with a viscosity that permits it to be processed easily in industrial plant, and which are suitable for administering the peptide to humans.
