Bioactive peptides are an important group of natural product sources isolated from marine organisms, plants, animals, and microorganisms. Bioactive peptides have been investigated to promote health because of their high tissue affinity, specificity, and efficiency. Therefore, they possess a key role in cancer, including early diagnosis, prognostic predictors, and treatment. Anticancer effects of peptides have been widely investigated and shown to have many advantages as peptide-based drugs. Many naturally occurring peptides such as plitidepsin, dolastatin 10, didemnin B, and kahalalide F are used in clinical trials for the treatment of various cancers. The structure-activity relationship of these peptides can contribute to the design and development of peptide-based drugs. The aim of this chapter is to review the recent developments in bioactive peptides and their role in cancer therapy. © 2022 Elsevier B.V.eninfo:eu-repo/semantics/closedAccessAnticancer; Bioactive peptides; Marine; Natural compounds; Structure-activityBook Chapter7532936510.1016/B978-0-323-91250-1.00009-42-s2.0-85139344432Q3
