PNC-27 Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research
PNC-27 is a synthetic anticancer peptide engineered to selectively destroy cancer cells by targeting HDM-2, a protein that appears on the outer surface of cancer cell membranes but not on normal cells. It kills cancer cells by binding to this surface target and punching transmembrane pores through the cell membrane, causing rupture and necrotic cell death. This mechanism operates independently of p53 tumor suppressor status, which is mutated or lost in roughly half of all human cancers. Research spans multiple cancer cell lines and documents a well-characterized cellular mechanism, but PNC-27 remains strictly preclinical: no human clinical trials have been registered or completed, no validated dosing exists, the FDA has issued safety warnings following confirmed bacterial contamination in commercially available products, and the human safety profile is entirely unknown.
