PNC-27 (PNC-27 (p53-Derived Anticancer Peptide))
An experimental peptide derived from the p53 tumor suppressor protein, studied for selectively destroying cancer cells. It remains preclinical and is included for educational reference; it is not an approved therapy.
How it works
Contains a p53 domain fused to a membrane-penetrating sequence. It is proposed to bind HDM-2 that is preferentially expressed on cancer cell membranes, forming pores that cause selective necrosis of cancer cells while reportedly sparing normal cells in studies.
Key facts
- Molecular weight: ~3.2 kDa
- Half-life: Short (peptide)
- Bioavailability: Injection (research)
- Storage: Lyophilized: -20°C (research material).
Dosing overview
- Typical dose: Not established for humans
- Frequency: Research only
- Duration: Research only
- Route: Injection (research)
Protocol notes
- No validated human dosing exists; all use is experimental and unapproved.
- Animal and cell studies used research-specific dosing regimens.
- Included for educational completeness, not as a cancer treatment.
Reported benefits
- Selective cancer-cell targeting (preclinical)
- p53/HDM-2 mechanism of interest
- Reported sparing of normal cells (studies)
Possible side effects
- Unknown human safety
- No approved human use
- Unproven efficacy in humans
Research
- PNC-27 selective cancer cell necrosis (2010): Reported to selectively induce necrosis of cancer cells via membrane HDM-2 binding while sparing normal cells in preclinical models.
Community reviews of PNC-27
- careful_claire rated it 5/5 - Solid compound with real results: Been using PNC-27 for about 1 month and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- lab_notes_tom rated it 4/5 - Noticed clear benefits within weeks: Added PNC-27 to my protocol about 6 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
- syringe_science_sue rated it 5/5 - Genuinely effective after 2 weeks: Been using PNC-27 for about 2 weeks and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- deep_science_dee rated it 4/5 - Worth adding to the protocol: PNC-27 has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
