Unlocking the ocean's potential: advancing marine natural products for cancer therapy with a focus on glioblastoma multiforme

Abstract Cancer, a multifactorial and heterogeneous disease, poses a significant global health challenge. Despite current treatments such as surgery, radiotherapy, and chemotherapy, tumour recurrence and treatment side effects are common. These pitfalls necessitate a dire need for alternative therapeutic strategies with minimal side effects. This necessity has broadened the horizons of drug discovery into the marine domain, an exciting frontier for novel therapeutic agents. The marine ecosystem serves as a hub of diverse chemical groups with potential anti-cancer properties. Few marine-derived drugs are approved for cancer, and preliminary studies show that marine lead compounds can inhibit cancer cell growth and induce apoptosis. In this context, this review encapsulates an overview of ‘the current state of marine biodiscovery’. It explores the ‘potential of marine natural products in combating cancer’ with a particular focus on glioblastoma multiforme as a case study. Additionally, it discusses the ‘key strategies for advancing marine-derived anti-cancer compounds from the research stage to clinical use’. By tapping into the vast, unlocking the hidden treasures of the ocean, marine natural compounds could offer a hopeful perspective in the fight against cancer.
