A new class of polyalkylene oxide vinyl sulfone reagents is described. Also described are a method by which these reagents can be prepared as well as a method for using them in hydrated media for the modification of proteins. The novel polymer-to-protein conjugates made by reacting these reagents with proteins have advantages over similar conjugates prepared with prior art reagents in that they are more stable against hydrolysis and retain the positive charge carrying capacity at amine sites at which the modifying reagents are attached.
描述了一种新型的聚烯烃氧化物乙烯砜试剂。还描述了一种制备这些试剂的方法,以及一种在水合介质中将它们用于修饰蛋白质的方法。通过将这些试剂与蛋白质反应制备的新型聚合物-蛋白质共轭物与使用先前技术试剂制备的类似共轭物相比具有优势,因为它们对水解更稳定,并且在连接修饰试剂的氨基位点上保留了正电荷携带能力。
