PNC-27 and 28, contain HDM-2-protein-binding domain sequences from the tumor suppressor p53 to induce pore formation in the membranes of a wide range of cancer cells but not any normal cells tested
PNC-27 selectively kills colon cancer stem cells by binding to membrane H/MDM-2. This was an in vivo study. As with other studies, the result was tumor cell necrosis and associated high LDH release.
PNC-27 binds to HDM-2 which is highly expressed on ovarian cancer cancer cell lines. The result is transmembrane pore formation and apoptosis independent cell necrosis.
