Marine-Derived Compounds: A New Horizon in Cancer, Renal, and Metabolic Disease Therapeutics

Marine-derived compounds represent a rich source of structurally diverse molecules with therapeutic potential for cancer, renal disorders, metabolic-associated fatty liver disease (MAFLD), and atherosclerosis. This review systematically evaluates recent advances, highlighting compounds such as Microcolin H, Benzosceptrin C, S14, HN-001, Equisetin, glycosides (e.g., cucumarioside A₂-2), ilimaquinone, and Aplidin (plitidepsin). Key mechanisms include autophagy modulation, immune checkpoint inhibition, anti-inflammatory effects, and mitochondrial homeostasis. Novel findings reveal glycosides' dual role in cytotoxicity and immunomodulation, ilimaquinone's induction of the DNA damage response, and Aplidin's disruption of protein synthesis via eEF1A2 binding. Pharmacokinetic challenges and structure-activity relationships are critically analyzed, emphasizing nanodelivery systems and synthetic analog development. This review bridges mechanistic insights with translational potential, offering a cohesive framework for future drug development.
