labeling of two reference peptidescontaining both an N-terminal amino function and a ε-amino group of a lysine residue in the backbone, and a supplementary thiol group of a cysteineresidue for one of these two peptides. The results showed the coupling to be efficient at pH 8.0, with a total selectivity for the terminal amine function with respect to lysine and cysteine. The labeling was further performed
Compounds of the following Formula (I):
in which
A represents either a nitrogen atom, or a ring having 3 to 6 carbon atoms, or an aromatic ring having 5 to 10 members, the ring and the aromatic ring optionally include one or more heteroatoms selected from N, O and S, and W represents a grafting function and X and Y represent chelating functions.
Pyrophosphate mimics: Iminodiacetic acid phosphoramidates of deoxyadenosine monophosphate analogues, either bearing an extended aliphatic chain in the amino acid function or a phosphonic acid moiety, serve as potential substrates for HIV‐1 reversetranscriptase. Iminodipropionicacid was found to be an excellent mimic of the pyrophosphate.
