Neoglycoconjugates as immunogens and therapeutic/diagnostic tools are described herein. The neoglycoconjugates are produced by conjugating a carbohydrate antigen intermediate to a free amine group of a carrier material (e.g., carrier protein). The intermediate comprises a linker having a first end and a second end, the first end being conjugated to a carbohydrate antigen via a thio ether bond and the second end comprising a functional group reactable with a free amine group. Following coupling, the carbohydrate antigen becomes covalently bound to the carrier material via an amide, a carbamate, a sulfonamide, a urea, or a thiourea bond, thereby producing the neoglycoconjugate. Applications of the neoglycoconjugates as antigens, immunogens, vaccines, and in diagnostics are also described. Specifically, the use of (neo)glycoconjugates as vaccine candidates and other therapeutic tools against cancers, viruses such as SARS-CoV-2, and other diseases characterized by expression of aberrant glycosylation are also described.
本文介绍了作为免疫原和治疗/诊断工具的新糖蛋白轭合物。新甘油三酯是通过将碳水化合物抗原中间体与载体材料(如载体蛋白)的游离胺基团共轭而制成的。中间体包括具有第一端和第二端的连接体,第一端通过硫醚键与碳水化合物抗原连接,第二端包括可与游离胺基团反应的官能团。偶联后,碳水化合物抗原通过酰胺键、氨基甲酸酯键、磺酰胺键、脲键或硫脲键与载体材料共价结合,从而产生新甘糖共轭物。此外,还介绍了新甘氨酸轭合物作为抗原、免疫原、疫苗以及在诊断中的应用。具体而言,还介绍了(新)糖轭合物作为候选疫苗和其他治疗工具,用于抗击癌症、SARS-CoV-2 等病毒以及以表达异常糖基化为特征的其他疾病。
