Description: | Dulaglutide (LY2189265) is a glucagon-like peptide-1 (GLP-1) receptor agonist. Sequence: His-Gly-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Glu-Gln-Ala-Ala-Lys-Glu-Phe-Ile-Ala-Trp-Leu-Val-Lys-Gly-Gly-Gly;HGEGTFTSDVSSYLEEQAAKEFIAWLVKGGG. |
Target: | GLP-1 receptor[1] |
In Vivo: | Dulaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist. No specific Dulaglutide-related cause of death is identified. Survival is numerically increased for both genders of animals in all Dulaglutide treatment groups and reaches statistical significance (P≤0.05) in the 0.5- and 5-mg/kg males and in the 0.05-, 0.5-, and 1.5-mg/kg females. Mean times to peak plasma concentration values of Dulaglutide are observed at 12 hours after dosing on day 1 and rang between 12 and 48 hours at week 52. The incidence of thyroid C-cell adenoma is significantly (P≤0.05) increased compare with controls in males and females at the Dulaglutide 0.5-, 1.5-, and 5-mg/kg doses[1]. |
Animal Administration: | The tumorigenic potential of Dulaglutide is evaluated in rats and transgenic mice. Rats are injected sc twice weekly for 93 weeks with Dulaglutide 0, 0.05, 0.5, 1.5, or 5 mg/kg corresponding to 0, 0.5, 7, 20, and 58 times, respectively. Transgenic mice are dosed sc twice weekly with Dulaglutide 0, 0.3, 1, or 3 mg/kg for 26 weeks[1]. |
