Description
Eloralintide (LY3841136) is a long-acting synthetic amylin analog studied as a selective amylin receptor agonist. The peptide is conjugated to a C20 fatty diacid moiety enabling reversible albumin binding and an extended plasma half-life consistent with once-weekly subcutaneous administration. In published preclinical work, eloralintide preferentially activates the human amylin 1 receptor (AMY1R), with reported selectivity of approximately 12-fold over the calcitonin receptor (CTR) and 11-fold over AMY3R — a profile differentiating it from non-selective amylin analogs such as cagrilintide. Eloralintide is investigated in research models for receptor pharmacology, food intake regulation, body composition, and gastrointestinal tolerability endpoints.
Benefits (Research Focus)
• Selective AMY1R agonism — studied for preferential activation of amylin 1 receptor over calcitonin and AMY3 receptors
• cAMP signaling — investigated for amylin receptor pharmacology and downstream signal transduction
• Food intake regulation — explored for satiety pathway endpoints in preclinical research
• Body composition research — examined for fat-mass and lean-mass partitioning in DIO models
• GI tolerability profile — researched for conditioned-taste-avoidance and gastrointestinal tolerance endpoints
What Researchers Look At
• Receptor binding affinity and selectivity across AMY1R / AMY3R / CTR
• cAMP activation curves in cell lines expressing amylin receptor subtypes
• Food intake, body weight, and adipose-tissue change in DIO rodent models
• Pharmacokinetics and albumin-binding driven half-life extension
• Comparative endpoints versus cagrilintide and pramlintide
