A method of making a synthetic glycopeptide, by addition of a synthetic oligosaccharide oxazoline to a GlcNAc-containing peptide precursor in the presence of an enzyme selected from among Endo-A and Endo-M. In a specific implementation, the method is utilized to synthesize a trivalent V3-domain glycopeptide including three V3-domain glycopeptides on a scaffold, wherein the three V3-domain glycopeptides are arranged to mimic the V3 domain presentation in trimeric gp120. Such trivalent V3- domain glycopeptides can be utilized in a vaccine for the treatment or prevention of HIV-1 infection.
一种合成糖肽的方法,通过在Endo-A和Endo-M中选择的酶的存在下,将合成的
寡糖噁唑线加入含有GlcNAc的肽前体。在一个具体的实现中,该方法被用于合成三价V3区域糖肽,包括三个V3区域糖肽在支架上,其中三个V3区域糖肽被排列以模拟三聚体gp120中的V3区域呈现。这样的三价V3区域糖肽可以用于治疗或预防HIV-1感染的疫苗中。
