MODIFIED AMINO ACIDS

摘要

The present invention provides a compound of the general formula (I), wherein X is the connection between the CO-hydrazine and the NR<SUP>1</SUP>-oxalic acid or ester group, and uses and synthesis methods. These compounds represent amino acid derivatives, wherein the amine group is turned into an acidic group by the oxalic acid group and the carboxylic acid is turned into an amine functionality by the hydrazine group; as well as peptidomimetics comprising the compound and methods for their synthesis.
