7 results about "Dianhydrohexitol" patented technology

Dianhydrohexitols are heterocyclic compounds that are obtained by double dehydration of hexitols such as mannitol and sorbitol. Among these diols the 1,4- and 3,6-dianhydrohexitols are well known under the names isosorbide, isoidide and isomannide.

Polyester carbonates based on alicyclic diacitors, 1,4:3,6-dianhydrohexitol, and specific amounts of additional aliphatic dihydroxy compounds.

ActiveJP7843249B2PolyesterPolymer science
The present invention relates to a method for preparing polyestercarbonates based on cycloaliphatic diacids, at least one 1,4:3,6-dianhydrohexitol, and at least one additional aliphatic dihydroxy compound, the polyestercarbonates prepared according to the method, and molding compounds and molded bodies containing the polyestercarbonates. The method according to the invention is a direct synthesis in which all structural elements forming the subsequent polyestercarbonate are already present as monomers in the first process step. It is characterized by a specific ratio of 1,4:3,6-dianhydrohexitol to at least one additional aliphatic dihydroxy compound being advantageous.

Isosorbide for use in the treatment of oral inflammatory conditions

PendingEP4768025A1AntipyreticAnalgesicsMouth mucosaMucosal inflammation
The present disclosure relates to 1,4:3,6-dianhydrohexitol, specifically isosorbide, and compositions comprising 1,4:3,6-dianhydrohexitol for treating oral inflammatory conditions. These conditions, which include both oral mucosal inflammation and periodontal diseases, are characterized by elevated levels of pro-inflammatory mediators, particularly IL-1 alpha and IL-8. Using the EpiOralâ„¢ model, isosorbide has demonstrated significant ability to reduce IL-1 alpha secretion and IL-8 gene expression in inflamed oral epithelial cells. These results support its therapeutic relevance in treating oral inflammatory conditions through modulation of key inflammatory mediators.
