Modified exendins and exendin agonists
View Patent ↗Novel modified exendins and exendin agonists having an exendin or exendin agonist linked to one or more polyethylene glycol polymers, for example, and related formulations and dosages and methods of administration thereof are provided. These modified exendins and exendin agonists, compositions and methods are useful in treating diabetes and conditions that would be benefited by lowering plasma glucose or delaying and/or slowing gastric emptying or inhibiting food intake.
1. A compound comprising exendin-4, or agonist analog of exendin-4, linked to a polyamino acid through the C-terminal amino acid of the exendin-4 or agonist analog of exendin-4 and wherein the polyamino acid is selected from the group consisting of poly(L-lysine), poly-glutamic acid, and poly-aspartic acid.
2. The compound according to claim 1 , wherein the polyamino acid is poly(L-lysine).
3. The compound according to claim 1 , wherein the compound comprises the exendin-4 linked to the polyamino acid.
4. The compound according to claim 3 , wherein the polyamino acid is poly(L-lysine).
5. The compound according to claim 1 , wherein the compound comprises the agonist analog of exendin-4 linked to a polyamino acid through the C-terminal amino acid of the agonist analog of exendin-4 and wherein the polyamino acid is selected from the group consisting of poly(L-lysine), poly-glutamic acid, and poly-aspartic acid.
6. The compound according to claim 5 , wherein the polyamino acid is poly(L-lysine).
