Conjugate of polyethylene glycol and chitosan

   
   

PEG-chitosan conjugates comprising chitosan and polyethylene glycol moieties or derivatives thereof which are bonded together and their use in medicine is described. In one embodiment, the conjugate comprises a chitosan moiety or a derivative thereof and a polyethylene glycol moiety or a derivative thereof which are bonded together via the amino function on the chitosan by the use of an activated chitosan species. In another embodiment, the conjugate comprises a chitosan moiety or a derivative thereof and a polyethylene glycol moiety or a derivative thereof which are bonded together, the chitosan portion of the conjugate having a molecular weight in the range of from 10 kilodaltons to 1000 kilodaltons.

Wpenek-chitosan спрягает состоять из chitosan и описаны moieties гликоля полиэтилена или производные thereof скреплены совместно и их польза в микстуре. В одном воплощении, конъюгат состоит из chitosan moiety или производного thereof и moiety гликоля полиэтилена или производного thereof который скреплены совместно через амино функцию на chitosan пользой активированного chitosan вида. В другом воплощении, конъюгат состоит из chitosan moiety или производного thereof и moiety гликоля полиэтилена или производного thereof который скреплены совместно, chitosan часть конъюгата имея молекулярный вес в ряде от 10 kilodaltons к kilodaltons 1000.
