  • Liquid phase peptide synthesis of KL-4 pulmonary surfactant
    Patent number: 8217142
    Abstract: The invention relates to improved liquid phase processes for the preparation of the 21 residue protein component, (Lys-Leu4)4-Lys, of the pulmonary surfactant KL-4. These process are amenable to large scale synthesis and one process employs a method of saponifying an ester which reduces the inherent racemization of the ?-carbon.
    Type: Grant
    Filed: September 30, 2008
    Date of Patent: July 10, 2012
    Assignee: Ortho Pharmaceutical Corporation
    Inventors: Ahmed F. Abdel-Magid, Urs Eggmann, Cynthia Anne Maryanoff, Adrian Thaler, Frank J. Villani

  • Transesterification and other conversion reactions of acid derivatives, using an amidine base
    Patent number: 6090913
    Abstract: A process employs amidine or amidine base and a metal compound in the presence of an alcohol or water to transesterify, or saponify esters or amides. Since the process employs relatively mild conditions, it is especially suitable for the production of optically active substances and biomolecules, e.g. peptides, amino acids and nucleic acids which are sensitive to elevated temperatures, extreme pH values and/or long reaction times since these compounds are easily racemised or denatured. The conditions additionally find use in solid phase systems. When amino acid or peptide esters are saponified, the splitting is brought about with lithium hydroxide alone under mild conditions. The use of an amidine base, more particularly DBU or DBN, in combination with the metal salt additionally accelerates the reaction so strongly that even sensitive acid derivatives can be reacted under mild conditions.
