Abstract: A water soluble biocompatible hydrogel having an amino sugar linked to a hydrophilic polymer is disclosed. Linkage of the amino sugar and hydrophilic polymer may be provided by an imine-amine bond between an amine of the amino sugar and a primary amine of the hydrophilic polymer. The linkage between the amino sugar and the hydrophilic polymer may be provided by reacting an amine of the amino sugar and a primary amine of the hydrophilic polymer with a formate ester in an acidic solution. Water soluble biocompatible polymer having an amino sugar linked to a hydrophilic polymer may be cast into films, dried into gauze and/or combined with salt solutions to provide injectable gels.

Abstract: Exemplary embodiments of the present invention relate to benzoxazines having various N-protecting groups. An R1 functional group is at least one selected from the group consisting of H and a halogen, an R2 functional group is at least one selected from the group consisting of H, an amide, or a carbamate, and a Z functional group is at least one selected from the group consisting of a phenyl, substituted phenyl group, methyl, and t-butyl group. The exemplary embodiments provide compounds with benzoxazines having various cleavable protecting groups such as amides and carbamates.
Abstract translation: 本发明的示例性实施方案涉及具有各种N-保护基团的苯并恶嗪。 R1官能团为选自H和卤素中的至少一种，R2官能团为选自H，酰胺或氨基甲酸酯的至少一种，Z官能团为至少 一个选自苯基，取代的苯基，甲基和叔丁基。 示例性实施方案提供具有各种可切割保护基团（如酰胺和氨基甲酸酯）的苯并恶嗪化合物。
