Abstract
The present invention relates to amphiphilic block copolymers comprising reduction sensitive biodegradable polyesteramides. The present invention also relates to micelles comprising the amphiphilic block copolymers. The invention also relates to drug delivery systems comprising the micelles. The amphiphilic block copolymers comprise hydrophilic and hydrophobic blocks whereby the hydrophobic blocks comprise a biodegradable polyesteramide based on alpha-amino acids, diols, aliphatic dicarboxylic acids and optionally diamines whereby at least one of the dicarboxylic acids, diols or diamines comprises disulphide linkages.
