Abstract RU 2575460 C2

FIELD: chemistry.

SUBSTANCE: invention relates to novel derivatives of anionic polysaccharides, partly functionalised by at least two vicinal hydrophobic groups, with said hydrophobic groups, being similar or different, being connected with at least trivalent radical or intermediate grouping. Invention also relates to methods for their synthesis.

EFFECT: invention relates to application of polysaccharides, functionalised in accordance with claimed invention, for stabilisation of protein active substances, where active substance is selected from the group, including proteins, glycoproteins, peptides and non-peptide therapeutic compounds.
