  • Tertomotide is a peptide vaccine developed for anti-cancer therapy. Since it has been found to ameliorate inflammatory symptoms in animal studies and clinical test, we investigated anti-inflammation activity of the tertomotide and the mechanism of action in monocyte in order to assess if tertomotide may serve as an anti-inflammatory agent by checking inflammatory cytokines and related signaling pathway following tertomotide treatment. We found that tertomotide reduced the level of pro-inflammatory cytokines such as TNF-α, IL-1β, IL-8 in LPS- or PMA-stimulated monocyte cell line and suppressed NF-κB signaling including the activation of ERK1/2 and P38 MAPK following TNF-α treatment. These results may correlate to the beneficial findings in animal studies, implicating that tertomotide may act as a potential anti-inflammatory agent. This study is an exemplary case for convergence that a computationally designed peptide for immunological purpose exerting unexpected biological activity may elicit novel anti-inflammatory drug.

  • Tertomotide is a peptide fragment of hTert and developed as a vaccine targeting cancer. It has been reportedly known to ameliorate inflammatory symptoms in clinical tests and in animal studies. However, the therapeutic potential of tertomotide is not supposed to be comparable to conventional anti-inflammatory agents due to low druglikeness In order to treat inflammations present in varous lesion, the structure of tertomotide is required to be modified. In this context, 12 octapeptides were designed based on tertomotide and screened for the anti-inflammatory activity in activated monocyte by measuring TNF-α secretion. As a result, some octapeptides has been exerted anti-inflammatory activity, comparable to or better than tertomotide and estradiol, known anti-inflammatory agents. This result is supposed to be helpful for developing therapeutic purpose exploiting other tertomotide-derived peptides and would be an example for designing novel drug based on active biomolecules with undesirable structure by convergence study of biology and computer-aided medicinal chemistry.
