    摘要: A method of preparing an assembled peptide comprising:

    a) binding a first peptide segment to a solid phase via a linker to form a solid phase-bound peptide;
    b) ligating at least a second peptide segment to said solid phase-bound peptide in aqueous solution to form a solid phase-bound peptide. Preferably the first and second peptide segments are unprotected, except that if the second peptide segment has an N-terminal cysteine, it is optionally protected.

    摘要: The invention is directed to methods and compositions for aqueous-compatible solid phase chemical ligation. The methods and compositions of the invention involve the chemical ligation of first and second polymers, where the first polymer is attached to a support through a displaceable linker. The displaceable linker can be cleaved or otherwise displaced under aqueous conditions compatible with subsequent removal of the ligation product from the solid support. The methods and compositions of the invention are particularly useful for ligation of peptides and polypeptides on a solid support. The ligation system of the invention is applicable to a wide variety of molecules, and thus can be exploited to generate ligated polymers including peptides, polypeptides and other amino acid containing polymers.

    摘要: The invention concerns a multiplex polymer ligation method involving water-soluble polymeric protecting groups, compositions and methods of use. The method involves synthesis of a first compound bearing one or more water-soluble polymeric protecting groups followed by replacing one or more of the water-soluble protecting groups with a chemical adduct of interest. Multiple different compounds derived from the first compound can be readily prepared by splitting the first compound into first and second reaction systems, followed by replacing one or more of the water-soluble polymeric protecting groups of the first reaction system with a first chemical adduct, and replacing one or more of the water-soluble polymeric protecting groups of the second reaction system with a second chemical adduct of interest, where the first and second chemical adducts are different. Also provided are kits useful for carrying out the multiplex polymer ligation methods of the invention.
