Special delivery! Polyionic complex (PIC) micelles that contain the charge-conversional moieties citaconic amide or cis-aconitic amide were developed for cytoplasmic protein delivery. The increase of the charge density on the protein cargo helped the stability of the PIC micelles without cross-linking, and the charge-conversion in endosomes induced the dissociation of the PIC micelles to result in efficient endosomal release (see picture).
特别递送!开发了含有电荷转换部分柠康酰胺或顺乌头酰胺的聚离子复合物(PIC)胶束用于细胞质蛋白递送。蛋白质载物上电荷密度的增加有助于PIC胶束在无交联情况下的稳定性,并且内体中的电荷转换诱导PIC胶束解离,从而实现有效的内体释放(见图)。
