  • Process for solubilizing glucagon-like peptide 1 compounds
    Patent number: 8455433
    Abstract: Disclosed is a method of preparing a GLP-1 compound that is soluble in aqueous solution at pH 7.4 from a GLP-1 compound that is substantially insoluble in aqueous solution at pH 7.4. The insoluble GLP-1 compound is dissolved in aqueous base or in aqueous acid to form a GLP-1 solution. The GLP-1 solution is then neutralized to a pH at which substantially no amino acid racemization of the GLP-1 compounds occurs, after which the soluble GLP-1 compound is isolated from the neutralized solution.
    Type: Grant
    Filed: August 10, 2012
    Date of Patent: June 4, 2013
    Assignee: Eli Lilly and Company
    Inventors: Walter Francis Prouty, Jr., Joseph Vincent Rinella, Jr.
