Thermoresponsive polymers have been widely studied in the past decades due to their potential applications in biomedicine, nanotechnology, and so on. As is known, poly(-isopropylacrylamide) (PNIPAM) and poly(oligo(ethylene glycol)methacrylates) (POEGMAs) are the most popular thermoresponsive polymers, and have been studied extensively. However, more advanced thermoresponsive polymers with excellent biocompatibility, biodegradability, and bioactivity also need to be developed for biomedical applications. OEGylated poly(amino acid)s are a kind of novel polymer which are synthesized by attaching one or multiple oligo(ethylene glycol) (OEG) chains to poly(amino acid) (PAA).These polymers combine the great solubility of OEG, and the excellent biocompatibility, biodegradability and well defined secondary structures of PAA. These advantages allow them to have great application prospects in the field of biomedicine. Therefore, the study of OEGylated poly(amino acid)s has attracted more attention recently. In this review, we summarized the development of thermoresponsive OEGylated poly(amino acid)s in recent years, including the synthesis method (such as ring-opening polymerization, post-polymerization modification, and Ugi reaction), stimuli-response behavior study, and secondary structure study. We hope that this periodical summary will be more conducive to design, synthesis and application of OEGylated poly(amino acid)s in the future.
在过去几十年中,热响应性聚合物因其在生物医学、纳米技术等领域的潜在应用而得到广泛研究。众所周知,聚(N-异丙基丙烯酰胺)(PNIPAM)和聚(甲基丙烯酸寡聚乙二醇酯)(POEGMAs)是最常见的热响应性聚合物,并且已被广泛研究。然而,为了生物医学应用,还需要开发具有优异生物相容性、生物降解性和生物活性的更先进的热响应性聚合物。寡聚乙二醇化聚氨基酸是一类新型聚合物,它是通过将一个或多个寡聚乙二醇(OEG)链连接到聚氨基酸(PAA)上合成的。这些聚合物结合了OEG的良好溶解性以及PAA优异的生物相容性、生物降解性和明确的二级结构。这些优点使其在生物医学领域具有广阔的应用前景。因此,近年来寡聚乙二醇化聚氨基酸的研究受到了更多关注。在这篇综述中,我们总结了近年来热响应性寡聚乙二醇化聚氨基酸的发展情况,包括合成方法(如开环聚合、后聚合修饰和乌吉反应)、刺激响应行为研究和二级结构研究。我们希望这一阶段性总结将更有利于未来寡聚乙二醇化聚氨基酸的设计、合成及应用。
