在氮气保护下,将4.7g(22mmol)6-马来酰亚胺基己酸(MC)和25g(22mmol)N-羟基丁二酰亚胺(HOSu)溶解于50ml乙腈中。另将4.5g(22mmol)N,N'-二环己基碳二亚胺(DCC)溶解于25ml乙腈中,并维持内部温度。在0℃条件下,将DCC溶液缓慢滴加至反应混合物中。反应混合物于0℃搅拌反应2小时,随后升至室温继续反应过夜。反应完成后,过滤除去沉淀,滤饼用乙腈洗涤(10ml×3)。合并滤液,减压浓缩至干。所得油状产物于室温下减压干燥6小时,得到6.4g浅棕色固体,即6-(马来酰亚胺基)己酸琥珀酰亚胺酯,产率为95%。

常见问题列表
6-(马来酰亚胺基)己酸琥珀酰亚胺酯是一种异双官能团交联试剂,与胺和巯基反应性的延长间隔结合。通常,最初通过pH 7.5缓冲的酰胺键与含有初级胺的分子耦合(6.5-8.5),第二次耦合是通过pH 6.8缓冲的硫醚键与含有游离巯基的分子耦合(6.5-7.0)。
6-(马来酰亚胺基)己酸琥珀酰亚胺酯可用于酶免疫偶联剂和半抗原载体分子偶联剂的制备。包含9个原子链接器。与芳香族间隔物相比,延长的脂肪间隔物在耦合前稳定了马来酰亚胺。
