Título: | Strategies to Fabricate Polypeptide-Based Structures via Ring-Opening Polymerization of N-Carboxyanhydrides |
Autor: | González-Henríquez, Carmen M.; Sarabia-Vallejos, Mauricio A.; Rodríguez-Hernández, Juan CSIC ORCID | Fecha de publicación: | 25-oct-2017 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Polymers 9 (11): 551 (2017) | Resumen: | In this review, we provide a general and clear overview about the different alternatives reported to fabricate a myriad of polypeptide architectures based on the ring-opening polymerization of <i>N</i>-carbonyanhydrides (ROP NCAs). First of all, the strategies for the preparation of NCA monomers directly from natural occurring or from modified amino acids are analyzed. The synthetic alternatives to prepare non-functionalized and functionalized NCAs are presented. Protection/deprotection protocols, as well as other functionalization chemistries are discussed in this section. Later on, the mechanisms involved in the ROP NCA polymerization, as well as the strategies developed to reduce the eventually occurring side reactions are presented. Finally, a general overview of the synthetic strategies described in the literature to fabricate different polypeptide architectures is provided. This part of the review is organized depending on the complexity of the macromolecular topology prepared. Therefore, linear homopolypeptides, random and block copolypeptides are described first. The next sections include cyclic and branched polymers such as star polypeptides, polymer brushes and highly branched structures including arborescent or dendrigraft structures. | Versión del editor: | http://doi.org/10.3390/polym9110551 | URI: | http://hdl.handle.net/10261/156775 | DOI: | 10.3390/polym9110551 | Identificadores: | doi: 10.3390/polym9110551 |
