PNC-27 vs Pinealon
Side-by-side comparison of key properties, dosing, and research.
- Summary
- 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.
- Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
- Half-Life
- Not well established; estimated minutes to hours
- Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
- Admin Route
- Intravenous (research), Intraperitoneal (research)
- SubQ, Oral, Intranasal
