POLYSUBSTITUTED POLYCARBOXYLIC PHOSPHOAMIDE BIOPOLYMERS, METHODS FOR THEIR PRODUCTION AND USES OF COMPOSITIONS DERIVED THEREFROM

摘要

The present invention provides polysubstituted polycarboxylic phosphoamide biopolymers (PPPBs) comprising polysaccharides and glycopolypeptides attached to a phospho-citrate backbone. Phosphorylation of the biopolymers yields phosphorylated polysubstituted polycarboxylic phosphoamide byopolymers (pPPPBs) which can be used as inflammatory response modulators, immunomodulators and/or biological response modifiers. Methods for producing the PPPBs in yeast subjected to multiple chemical stressors, and uses of compositions derived therefrom, are provided.
