متن کاملFormulation of Modified Microspheres Based on Cyclodextrin-Lactic Acid Polymers
Polymers, based on Poly L-lactic acid (L-PLA) and coupled with β-Cyclodextrin (β-CD), have been used for the preparation of microspheres for drug encapsulation. The strategy was based on the modification of the terminal carboxylic group of L-PLA (73.000) by coupling it with a β-CD in the presence of the peptide coupling agents: DCC/HOBT. The degree of functionalisation was found to be 80%. Char...
