STABILIZED POLYPEPTIDE INSULIN RECEPTOR MODULATORS

摘要

Provided herein are stabilized α-CT polypeptides comprising an alpha-helical segment, and wherein the polypeptide is of Formula (I-1) or Formula (I-2): Rf—[XAA]s—XA1—XA2—XA3—XA4—XA5—XA6—XA7—XA8—XA9—XA10—XA11—XA12—XA13—XA14—[XAA]t—Re (I-1) Rf—[XAA]s—XC1—XC2—XC3—XC4—XC5—XC6—XC7—XC8—XC9—XC10—XC11—XC12—XC13—XC14—XC15—XC16—XC17—XC18—XC19—XC20—[XAA]t—Re (I-2) wherein the α-CT polypeptide binds to the insulin receptor, and wherein the α-CT polypeptide includes at least one staple (i.e. two cross-linked amino acids) and/or at least one stitch (i.e. three cross-linked amino acids). Further provided are insulin analogues including the stapled or stitched α-CT polypeptides, pharmaceutical compositions thereof, methods of use, e.g., methods of treating a diabetic condition or complications thereof.
