Abstract: The present invention is directed to novel products, variants, pharmaceutically acceptable salts and prodrugs thereof, and medical use of such compounds for the treatment and/or management of sepsis, septicemia, septic shock, peritonitis, skin and soft tissue infections, ocular infection, ocular inflammation, ocular angiogenesis, rheumatoid arthritis (RA), atherosclerosis, inflammatory bowel diseases (IBD), necrotizing enterocolitis, asthma, chronic obstructive pulmonary disease, acute respiratory distress syndrome, acute lung injury, bacterial and viral pneumonia, chronic lung injury, acute kidney injury, chronic kidney injury, fibrosis, fever syndromes, cachexia, psoriasis, autoimmune diseases, cardiac diseases, retinoblastoma, cancer and/or any disorder associated with inflammation, immunomodulation and microbial infection.

Abstract: The present invention relates to the development of a hyaluronic acid and hyaluronic acid hybrid nanoparticle systems for the administration of active molecules, peptides, DNA and/or other hydrophilic or hydrophobic molecules, the composition of hyaluronic acid and hyaluronic acid hybrid nanoparticle systems, and the procedure for their development and use. These nanoparticles are made up of hyaluronic acid in salt form, preferentially the sodium salt of the polymers or hybridized with magnetic Fe particles. The nanoparticles are basically from natural polymers, biocompatibles and biodegradables. The nanoparticles allow the controlled release of the active molecules they transport and their orientation towards the target tissues. The present invention teaches a procedure to elaborate particles of hyaluronic acid with a diameter less than 180 nm., that incorporate an active ingredient, independent of its hydrophilic or hydrophobic nature. Procedures to produce the particles are described.
