HYDROXYALKYL STARCH DERIVATIVES Russian patent published in 2008 - IPC C08B31/12 C07K17/02 C07K17/10 A61K47/36 A61K38/17 A61P7/06 

FIELD: chemistry.

SUBSTANCE: invention concerns process of obtaining hydroxyl starch derivative which includes interaction of the reducing end of hydroxyalkyl starch represented by the formula (I), left unoxidised before this reaction, with a compound of formula (II) R'-NH-R", where R₁ R₂ and R₃ independently denote hydrogen or linear or branched hydroxyalkyl group while R' or R" or R' and R" include at least one functional group X capable of interaction with at least one more compound before or after the reaction of (I) and (II). The invention also concerns hydroxyl starch derivative obtained in this process, and production process for hydroxyl starch derivative and polypeptide, a pharmaceutical composition incorporating the said hydroxyl starch derivatives.

EFFECT: improvement of compound production.
