ABSTRACT:
The present invention provides modified amino acids for delivering active agents, and particularly biologically or chemically active agents. The preferred modified amino acids of the present invention include N-acylated or sulfonated amino acids. These modified amino acids are used as carriers to facilitate the delivery of a cargo to a target. Such modified amino acids are well suited to form non-covalent mixtures with biologically-active agents for oral administration to animals. Methods for the preparation and administration of the modified amino acids and compositions including the same are also provided.
