    摘要: The instant invention provides two-chain IGF-1 superagonists which are derivatives of the naturally occurring single-chain IGF-1 having an abbreviated C domain. The invention also provides synthetic and semi-synthetic DNA sequences, recombinant DNA vectors and transformed host cells useful in the recombinant production of these analogs. The invention also provides pharmaceutical formulations comprising these IGF-1 analogs. The invention also provides methods of using these analogs in a variety of therapeutic applications. The instant invention provides IGF-1 analogs of the formula:BC.sup.n,A (1)wherein:B is the B domain of IGF-1 or a functional analog thereof,C is the C domain of IGF-1 or a functional analog thereof,n is the number of amino acids in the C domain and is from about 6 to about 12, andA is the A domain of IGF-1 or a functional analog thereof.

    摘要: Prodrug formulations of insulin and insulin analogs are provided wherein the insulin peptide has been modified by an amide bond linkage of a dipeptide prodrug element. The prodrugs disclosed herein have extended half lives of at least 10 hours, and more typically greater than 2 hours, 20 hours and less than 70 hours, and are converted to the active form at physiological conditions through a non-enzymatic reaction driven by chemical instability.
