Eloralintide
Based on 1 Customer Validation
Eloralintide (LY-3841136) is an amylin receptor agonist with human AMY1R EC50 23.9 pM and human AMY3R EC50 253.8 pM. Eloralintide induces decreased appetite, reduced food intake, body weight and fat mass loss, prolonged plasma calcium2+ reduction, and weak conditioned taste avoidance. Eloralintide can be used for the research of obesity.

Biological Activity
Eloralintide acts as an agonist of both rat and human amylin receptors (AMYRs) and calcitonin receptors (CTRs)[2].
Eloralintide selectively activates human AMY1R (EC50 = 23.9 pM) with 11- to 12-fold greater potency than human AMY3R and CTR, and acts as a full agonist at all three human receptors[3].
Eloralintide binds human AMY1R (Ki = 478.1 pM) with 8-fold greater affinity than human AMY3R and CTR[3].
Eloralintide selectively activates rat AMY1R (EC50 = 5.4 pM) with 3-fold greater potency than rat AMY3R and 45-fold greater potency than rat CTR, and acts as a full agonist at all three rat receptors[3].
Eloralintide binds rat AMY1R (Ki = 48.1 pM) with 3-fold greater affinity than rat AMY3R and 109-fold greater affinity than rat CTR[3].

Eloralintide (0.1-100 nmol/kg; s.c.; Q3D; 13-15 days) dose-dependently reduces food intake and body weight in diet-induced obese male Long Evans rats, primarily via fat mass loss, with an ED50 of 0.8 nmol/kg for fat mass loss[3].

Animal Model:Long Evans (male, diet-induced obese)[3]
-
Dosage:0.1 nmol/kg; 0.3 nmol/kg; 1 nmol/kg; 3 nmol/kg; 10 nmol/kg; 30 nmol/kg; 100 nmol/kg (13 days); 1 nmol/kg; 10 nmol/kg; 100 nmol/kg (15 days)
-
Administration:s.c.; Q3D; 13 days; 15 days
-
Result:Induced dose-proportional reductions in food intake and body weight.
Reduced mean body weight by -12.3% from baseline at day 13 post-dose at 100 nmol/kg Q3D.
Caused fat mass to account for 85%, 77%, and 68% of total body weight loss at doses of 10, 30, and 100 nmol/kg Q3D, respectively.
Achieved an ED50 of 0.8 nmol/kg for fat mass loss, which was significantly lower than that of cagrilintide.
Reduced mean body weight by -11.0% from baseline at day 15 post-dose at 100 nmol/kg Q3D in head-to-head study, with fat mass accounting for 80% of total body weight loss.
Caused significantly less lean mass loss than cagrilintide at 100 nmol/kg Q3D.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (0.55 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (0.55 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
