Eloralintide- Summary
- AHK-Cu is a copper tripeptide composed of alanine, histidine, and lysine chelated to copper. Distinct from GHK-Cu, AHK-Cu exhibits strong affinity for hair follicle receptors and demonstrates potent hair growth stimulation alongside wound healing and skin regeneration properties.
- Eloralintide is a long-acting amylin analog under development by OPKO Health. Amylin is co-secreted with insulin and regulates post-meal glucose by slowing gastric emptying, suppressing glucagon, and promoting satiety. Eloralintide is designed for once-weekly dosing, differentiating it from the short-acting pramlintide (Symlin). It is being studied for obesity and type 2 diabetes as a complement to GLP-1 based therapies.
