PNC-27- Summary
- Liraglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and chronic weight management (Saxenda). It reduces appetite, slows gastric emptying, improves insulin secretion, and promotes weight loss of 5–10% in clinical trials.
- PNC-27 is a synthetic peptide derived from the p53 tumor suppressor protein, containing both an HDM2-binding domain and a transmembrane penetratin sequence. It selectively kills cancer cells by binding MDM2/HDM2 overexpressed on the plasma membrane of malignant cells, inducing membranolysis without harming normal cells.
