What PNC-27 is
An in-vitro cancer-cell-lysing peptide sold online as a cancer cure in nebulized, injectable and other forms; the FDA warned the public after finding bacterial contamination in a product, and no human trial has ever been registered.
PNC-27 is a p53-derived peptide that binds membrane-bound HDM-2 on cancer cells and punches holes in them in culture. Nothing beyond cell studies exists: no animal efficacy program, no registered clinical trial.
Mechanism: Binds HDM-2 expressed on cancer-cell membranes and forms transmembrane pores causing lysis (in vitro).
Regulatory history: Not approved; FDA public warning issued for contaminated product
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for PNC-27 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
