Targeting and inhibiting angiogenesis is a promising strategy for treatment of cancer. NGR peptide motif is a tumor-homing peptide, which could bind with CD13 expressed on tumor blood vessels. Lidamycin is a highly potent antitumor antibiotic, which is composed of an apoprotein (LDP) and an active enediyne chromophore (AE). Here, an NGR-integrated and enediyne-energized apoprotein composed of cyclic NGR peptide and lidamycin was developed by a two-step procedure. Firstly, we prepared the fusion protein composed of NGR peptide and LDP by recombinant DNA technology. Then, AE was reloaded to the fusion protein to get NGR-LDP-AE. Our experiments showed that NGR-LDP could bind to CD13-expressing HT-1080 cells, whereas the recombinant LDP (rLDP) showed weak binding. NGR-LDP-AE exerted highly potent cytotoxicity to cultured tumor cells in vitro. In vivo antitumor activity was evaluated in murine hepatoma 22 (H22) model and human fibrosarcoma HT-1080 model. At the tolerable dose, NGR-LDP-AE and lidamycin inhibited H22 tumor growth by 94.8 and 66.9%, and the median survival time of the mice was 62 and 37 days, respectively. In the HT-1080 model, NGR-LDP-AE inhibited tumor growth by 88.6%, which was statistically different from that of lidamycin (74.5%). Immunohistochemical study showed that NGR-LDP could bind to tumor blood vessels. Conclusively, these results demonstrate that fusion of LDP with CNGRC peptide delivers AE to tumor blood vessels and improves its antitumor activity.
