| 摘要 |
The invention provides methods and compositions useful for making synthetic peptide conjugates. In one embodiment, the invention provides compositions comprising the structure:wherein R is selected from lower substituted or unsubstituted alkyl, O, NH and S and P is an amine protection group. In more particular embodiments, the compositions comprise alpha-amine protected 4,5-dehydroleucine or alpha-amine protected (2S)-aminolevulinic acid and/or P is F-moc. These compounds may be incorporated into peptides, for example, peptides comprising a substituted or unsubstituted (2S)-aminolevulinic acid residue, such as (2S)-aminolevulinic acid residue is substituted with an O- or N-linked glycoconjugate, or a detectable label.
