Palmitoyl Tetrapeptide-7- Summary
- Mazdutide is a once-weekly GLP-1/glucagon dual receptor agonist developed by Innovent Biologics and Eli Lilly. Phase 2 trials in Chinese populations demonstrated up to 11.3% body weight reduction at 6 mg over 24 weeks. It also improves liver fat, glycemic control, and lipid profiles. Phase 3 trials are ongoing primarily in China.
- Palmitoyl Tetrapeptide-7 (Rigin) is a cosmetic peptide consisting of palmitic acid linked to the tetrapeptide sequence GQPR (Gly-Gln-Pro-Arg). It was designed to mimic the biological activity of the IgG immunoglobulin C-terminus, which downregulates the production of interleukin-6 (IL-6), a key driver of skin aging and inflammation.
