                      Pharmaceuticals from marine sources: past, present and future

                      image-f43a15f807750ee2f1a01e5a91dac944f228c2e8-669x734-png

                      Co-authored by MARBLES partner Marcel Jaspars from University of Aberdeen (UNIABDN), this article reviews the factors that make marine natural products such a desirable target for drug discovery in the future, including the field's history, clinical trial accomplishments, and the challenges of achieving clinical approval.

                      Key points:

                      • Marine invertebrates and microorganisms produce novel marine natural products (MNPs) with potent and selective activity against many human diseases
                      • Marine biodiversity is greater than that on land with more than 20 marine animal phyla having no terrestrial representatives
                      • The greater the biological diversity investigated, the greater the chemical diversity that will be found — many of these marine-derived pharmaceuticals have novel mechanisms of action
                      • About 15–20 compounds of marine origin have been approved for human use against cancer, pain, heart disease and viral infections, with many more in the pipeline
                      • Aquaculture, chemical synthesis, and molecular genetics can supply material for clinical trials and clinical use;
                      • Antibody drug conjugate warheads developed from MNPs continue to feed the early clinical pipeline and offer exciting new avenues for MNP-based therapeutics
                      • Although anti-cancer properties have been primarily studied, preclinical pharmacology of novel MNPs has demonstrated antibacterial, antifungal, antimalarial, antituberculosis, antiviral, antidiabetic, anti-inflammatory as well as immune and nervous system bioactivity
                      • Understanding the mechanism of action added tremendous value to MNPs as they provide opportunities to decipher new biology that can be exploited to develop first-in-class therapeutics
                      • Technical improvements have sped up the time taken to isolate and structurally characterise novel compounds whilst reducing effort wasted on the rediscovery of known compounds
                      • These combined scientific advancements mean that pharmaceutical companies now regard marine natural product-derived pharmaceuticals with renewed interest.

                      Within MARBLES, Marcel Jaspars leads Work Package 4 - Small Molecules-Generation of Chemical Diversity, which focuses on compound characterisation and modification. Known compounds are dereplicated (MS-MS networking, metabolomics, in silico dereplication based on biosynthetic genes), compounds isolated, and the chemical structures of novel compounds elucidated.
