PNC-27

Also known as: p53-derived anticancer peptide

PNC-27 is a synthetic peptide containing a p53 C-terminal fragment linked to a cell-penetrating peptide sequence. It was designed to selectively kill cancer cells by targeting the HDM2 (human double minute 2) protein that is overexpressed on cancer cell membranes. In vitro studies show selective cytotoxicity against various cancer cell lines while sparing normal cells. No human clinical trials exist.

Mechanism of Action

Binds to HDM2 protein on cancer cell surfaces, forming pore-like structures in the cancer cell membrane that lead to membranolysis and necrotic cell death. Normal cells with low surface HDM2 expression are theoretically spared. The selective membrane-disruption mechanism is distinct from conventional apoptosis-inducing cancer therapies.

Dosing Research

No human dosing established. Underground use reports vary widely. In vitro effective concentrations are in the micromolar range. Translation to in vivo dosing is highly uncertain due to bioavailability, distribution, and stability concerns.

Side Effects & Risks

No human safety data whatsoever. Theoretical risks are severe: off-target membrane disruption in normal cells, immune reactions, and unpredictable toxicity. Using an unproven anticancer peptide outside of clinical trials carries extreme risk. This compound should not be self-administered.
