The invention pertains to chemoselective sensitivity booster for tagging a peptide, peptide conjugate, or similar reactive molecule for analysis of a peptide, protein, antibody, protein bioconjugate, antibody bioconjugate, and similar analytes. The sensitivity booster comprises of sp2 or sp3 nitrogen centers in combination with hydrophobic carbon chains linked with an electrophile or nucleophile for attachment with a peptide, peptide conjugate, or molecules with similar reactivity.
Drawing inspiration from the initiating amino acid modification in biosynthetic peptides, we have successfully demonstrated a biomimetic mechanism for N-to-C terminal extension in prebiotic peptide synthesis. This achievement was accomplished by using acetylated amino acid amides as the N-terminal substrate for peptide synthesis and amino acid amides as the C-terminal extension, with the reaction carried
受生物合成肽中起始氨基酸修饰的启发,我们成功证明了益生元肽合成中 N 至 C 末端延伸的仿生机制。这一成果是通过使用乙酰化氨基酸酰胺作为肽合成的N端底物,以氨基酸酰胺作为C端延伸,反应在80℃下以干湿循环进行,不需要任何活化剂。这为益生元肽的形成提供了一条合理的途径。
