Open the CIPO recordAbstract From the Canadian patent
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.

Why it's free to use
- Filed March 4, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 4, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 4, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
