Description

一种多臂单一分子量聚乙二醇及其活性衍生物及其制备和应用 技术领域
本发明涉及聚乙二醇功能材料技术领域,具体涉及一种多臂单一分子量聚乙二醇及其活性衍生物及其制备和应用,特别是在制备药物结合物、凝胶材料、药物载体和医疗器械产品中的应用。
背景技术
官能团化的聚乙二醇接枝到药物等生物活性分子上,可提高药物等的水溶性、生物相容性和稳定性,并可降低药物的毒性。官能团化的聚乙二醇作为生物活性分子改性剂已经在广泛应用于生物医药领域。虽然现在合成的聚乙二醇产品的分子量分布已经相当窄,但其仍旧是不同分子量聚乙二醇的混合物,其中含有的杂质往往导致对生物活性分子修饰过程的重复性难以保证。
在药物等生物活性分子的研究应用中,避免引入混合物是普遍采用的策略,高纯度是最终产物追求的主要目标之一,因此,人们希望制备出高纯度的单一分子量PEG衍生物应用于药物等领域。目前,直链状的单一分子量PEG应用与生物医药领域已有一些报道,如低分子量的单一分子量PEG衍生物作为细胞毒素和抗体的连接体,可应用于抗体偶联药物(ADC)领域。
与直链PEG产品相比,多臂的单一分子量PEG产品可有效提高单位载药量;同时,由于多臂产品的端位可为异官能团,一个分子体系中可以同时连接两种甚至三种药物,可以一药治多病;其还可以作为连接子应用于ADC体系中,从而大大提高单个ADC分子的载药量。此外,在医疗器械领域中,多臂聚乙二醇可作为交联剂,应用于制作凝胶,这些凝胶可在医疗器械中作为粘合剂、防渗透剂、防粘连剂和止血材料等。多臂单一分子量PEG及其衍生物拥有较为广阔的应用前景。但是,由于多臂单一分子量PEG产品的合成难度大,合成成本较高,难于规模化生产。
