PNC-27 is a peptide that targets cancer cells and destroys them, while leaving healthy cells unharmed. It does this by creating holes in the membranes of cancer cells, causing them to die due to the osmotic pressure difference. The peptide works by binding to a protein called HDM-2, which is found in cancer cells' membranes. Animal studies have shown that PNC-27 is effective in selectively targeting a variety of specific forms of cancer. While clinical trials have not yet been conducted, research has shown great promise for the PNC-27 peptide as a future anti-cancer drug. Side effects have been observed in animal studies, but successful outcomes have been noted.
