  • Publication number: 20010018201
    Abstract: Nine efficient aldolase antibodies were generated using hapten 2. This hapten combines, in a single molecule, structural components employed for reactive immunization with structural components employed for forming a transition state analog of the aldol reaction. Characterization of two of these antibodies reveals that they are highly proficient (up to 1000-fold better than any other antibody catalyst) and enantioselective catalysts for aldol and retro-aldol reactions and exhibit enantio- and diastereo-selectivities opposite that of antibody 38C2.

  • Patent number: 6071510
    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.
