Abstract
Marine environments harbor a wealth of bioactive peptides with potential anticancer properties, sourced from diverse organisms like tunicates, sea sponges, and mollusks. Through isolation, identification, and modification, peptides such as Stylisin and Papuamides have shown enhanced activity and progressed to clinical trials, underscoring their therapeutic promise. Enzymatic hydrolysis emerges as a favored method for peptide extraction from marine proteins, with sponges identified as particularly rich sources. Compounds like Jaspamide and Homophymins exhibit potent cytotoxic activity against cancer cells, highlighting their therapeutic potential. Additionally, peptides from ascidians and mollusks, including Aplidine and Kahalalide F, demonstrate significant anticancer properties. The study delves into peptides affecting apoptosis, microtubule dynamics, and angiogenesis inhibition, offering insights into potential cancer treatment mechanisms. Marine-derived peptides hold great promise as valuable candidates for novel anticancer therapies, with ongoing research aimed at unlocking their full therapeutic benefits.
