  • Patent number: 10696621
    Abstract: The present invention relates to a novel chiral phase-transfer catalyst, and a method for preparing an alpha-amino acid by using the same. According to the present invention, an alpha-amino acid of high optical purity could be synthesized in a high yield under an easy industrially applicable reaction condition by using a novel cinchona alkaloid compound as a chiral phase-transfer catalyst, and thus the present invention can be used as a key technique of the asymmetric alpha-amino acid synthesis and preparation field.

  • Publication number: 20100305311
    Abstract: Disclosed are nanoparticles for use in the isolation of peptides, a method for producing the nanoparticles, and a method for the isolation of peptides using the nanoparticles. The nanoparticles comprise magnetic nanoparticles and thiol-specific functional groups as first functional groups bound to the surfaces of the magnetic nanoparticles to selectively capture cysteine-containing peptides. The nanoparticles allow highly selective isolation of target peptides in a simple and rapid manner. Therefore, the nanoparticles can be applied to research on the treatment of diseases such as cancers.
