Pro-apoptotic peptides may be promising agents for cancer therapy owing to their ability to induce apoptosis in cancer cells. TatBim, a fusion peptide of Tat cell-penetrating peptide (CPP) and the BH3 domain derived from Bim apoptosis-inducing protein, is a pro-apoptotic peptide. In this study, based on the TatBim sequence, we attempted to minimize the CPP-Bim peptide while retaining apoptosis-inducing activity. The CPP and Bim parts were systematically shortened, and the pro-apoptotic activities of the shortened peptides were examined. We obtained TatBim-N1C2 and R8Bim-N1C2 as minimized peptides with efficient apoptotic activity. These peptides may have potential applications in future biomedical studies, such as cancer therapeutics.
