| Outline of Final Research Achievements |
Molecular self-assembly provides diverse approaches to construct nanostructured or multifunctional materials at various scales and dimensions. We have studied peptide lipids that self-assemble to form nanofibers responsive to enzymes. Here we studied cancer cell death initiated by enzymatic transformation of a peptide lipid. The peptide lipids were designed to form cytotoxic surfactants via enzymatic transformation by an enzyme secreted from cancer cells. We adopted matrix metalloproteinase that is excessively produced by some of cancer cells. Peptide lipids, which were respond or non-respond to the enzyme, were synthesized. One of the peptide lipids exhibited remarkable cytotoxicity to some of cancer cell lines, indicating the cell-selective cytotoxicity. Microscope observation also revealed that the cancer cells were decomposed after the addition of the peptide lipids. These results indicate that MMP transformed the peptide lipids to cytotoxic surfactants in cancer cells.
