Tripeptide-29- Summary
- 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.
- Tripeptide-29 is a pro-collagen cosmetic peptide composed of proline, hydroxyproline, and glycine — the core repeating unit of collagen. Applied topically, it signals dermal fibroblasts that collagen degradation has occurred, triggering compensatory new collagen synthesis.
