摘要

Anticancer oligopeptides are rarely studied because they are often present in very low concentrations in a complex matrix. In the current study, twelve oligopeptides were isolated and the amino acid sequence identified from the centipede. MTT results indicated that Trp–Gly–His–Glu ( CO-10 ) showed excellent anti-proliferative potency against chondrosarcoma cells in vitro . Further study showed that CO-10 induced SW1353 cells apoptosis and blocked cell cycle in the G0/G1 phase. Further, results demonstrate that the apoptotic and cytotoxic effects of CO-10 are mediated by the intrinsic mitochondria-mediated apoptotic pathway, which in turn causes the release of cytochrome c and the activation of caspases. This study will be important for the development of pharmaceutical anticancer peptides from natural products as anticancer agents against chondrosarcoma.
