PNC-28 is a synthetic chimeric peptide derived from the p53 protein and a cell-penetrating penetratin sequence, investigated for its selective cytotoxic activity against cancer cells in preclinical models. Research focuses on its ability to induce membrane disruption and necrotic cell death in tumor cells while showing limited activity against non-transformed cells, making it a tool for studying peptide-based mechanisms of selective tumor-cell targeting.

What Are The Purported Benefits Of PNC-28 (20mg)?

PNC-28 (20 mg) is a synthetic research peptide studied for its selective activity in cancer-cell models. It is widely discussed in preclinical oncology research due to its potential to interact with tumor-cell membrane targets and trigger rapid cell death pathways in certain experimental settings.

Key areas of interest in the literature include:

  • Differential Activity in Tumor vs. Non-Transformed Cell Models: PNC-28 has been studied for its ability to affect cancer cells, while showing limited activity against non-transformed cells under certain laboratory conditions.
  • Necrosis-Related Mechanism: Unlike many compounds studied for apoptosis-related pathways, PNC-28 has been investigated for its ability to induce rapid membrane disruption and necrotic cell death in tumor models.
  • Broad Preclinical Interest: Research has explored PNC-28 across multiple human tumor cell lines, including pancreatic, breast, and sarcoma cell lines.
  • HDM-2 Membrane Expression and p53-Independence: PNC-28 has been studied in cancer cell systems, including those with compromised or absent p53 function. Research suggests its activity is mediated through membrane-expressed HDM-2 rather than through canonical p53-dependent pathways, making it of interest in models where p53-dependent responses are impaired.

These findings are based on preclinical and experimental research and should not be interpreted as evidence of established clinical efficacy.

What Is The Chemical Makeup Of PNC-28 (20mg)?

PNC-28 is a 27-amino-acid chimeric peptide, meaning it combines two functional peptide segments into one molecule. It is derived from a p53-related sequence linked to a cell-penetrating penetratin sequence, which is used in research to support cellular entry.

Structural Components

  • p53-derived domain: Includes a fragment corresponding to the MDM-2/HDM-2 binding region of the p53 protein
  • Penetratin domain: A membrane-translocating sequence derived from the Antennapedia homeodomain

Technical Data

  • Sequence: Glu-Thr-Phe-Ser-Asp-Leu-Trp-Lys-Leu-Leu-Lys-Lys-Trp-Lys-Met-Arg-Arg-Asn-Gln-Phe-Trp-Val-Lys-Val-Gln-Arg-Gly
  • CAS Number: 392661-17-5
  • Subcategory: Research & Oncology Peptides
  • Molecular Formula: C₁₆₄H₂₅₅N₄₇O₃₇S
  • Molecular Weight: 3509.13 g/mol

This structural design is one reason PNC-28 is frequently studied in peptide oncology research, especially in experiments focused on peptide-cell membrane interactions.

What Does Scientific Research Say About PNC-28 (20mg)?

Published preclinical research describes PNC-28 as a peptide of interest because of its proposed membrane-targeting mechanism in certain tumor cells. Studies have explored how PNC-28 may bind to HDM-2/MDM-2-associated targets on cancer-cell membranes, thereby contributing to rapid membrane disruption.

Key Research Themes

  • Pore Formation / Membrane Disruption: Electron microscopy-based studies have reported ring-like assemblies consistent with membrane pore formation in tumor cell models following peptide exposure.
  • Rapid Cytotoxic Response in Models: Experimental findings suggest cell death can occur over short timeframes (minutes to hours) in susceptible cancer-cell systems.
  • Animal Model Observations: Some preclinical studies (including xenograft models) have reported tumor-response findings following local or systemic administration in research settings.
  • Research Status: PNC-28 remains an experimental peptide investigated in laboratory and preclinical oncology studies, and it should be presented as a research compound rather than a therapeutic product.

What Are The Storage Conditions For PNC-28 (20mg)?

Proper storage is important for maintaining the stability and integrity of PNC-28 (20 mg), particularly because the peptide contains tryptophan (W), which can increase sensitivity to oxidation and light exposure.

  • Lyophilized Powder (Unreconstituted)
    • Refrigerated (4°C): Recommended for long-term stability.
    • Frozen (-20°C to -80°C): Best for long-term preservation.
  • Reconstituted Solution (Liquid)
    • Refrigerated (2°C to 8°C): For short-term use, minimize degradation over time.
    • Frozen (-20°C): Can be stored for short periods; avoid repeated freeze-thaw cycles.

For best handling, store PNC-28 (20 mg) in a light- and heat-protected environment, and use low-temperature storage whenever possible for long-term preservation. Always follow supplier-specific storage instructions if provided, as formulation and packaging may affect stability.
