Title : Nature’s chemistry arsenal: Plant and marine bio actives in cellular defense and cancer suppression
Abstract:
Nature represents an unparalleled reservoir of chemically diverse bioactive compounds with profound implications for human health. Plants and marine organisms, shaped by evolutionary pressures, have developed sophisticated chemical defense systems that translate into potent pharmacological activities in human cells. This abstract explores the general role of plant- and marine-derived bio actives in cellular defense mechanisms and cancer suppression, highlighting their molecular targets and therapeutic potential.
Phytochemicals such as polyphenols, flavonoids, terpenoids, and alkaloids exhibit strong antioxidants, anti-inflammatory, and epigenetic modulatory properties. These compounds enhance cellular resilience by neutralizing reactive oxygen species, regulating signaling pathways (e.g., NF-κB, MAPK, and PI3K/Akt), and promoting DNA repair mechanisms. In parallel, marine-derived compounds, including sulfated polysaccharides, peptides, carotenoids, and unique secondary metabolites from algae, sponges, and microorganisms, demonstrate remarkable cytotoxic selectivity against cancer cells while sparing normal tissues.
Both plant and marine bio actives contribute to cancer suppression through multiple mechanisms: induction of apoptosis, inhibition of angiogenesis, modulation of immune responses, and interference with tumor cell proliferation and metastasis. Importantly, these natural compounds often act synergistically, offering a multi-targeted approach that addresses the complexity of cancer biology and reduces the likelihood of resistance.
Emerging research emphasizes the integration of these bio actives into advanced delivery systems, including nanotechnology-based carriers, to enhance bioavailability and therapeutic efficacy. As the global burden of cancer continues to rise, nature’s chemical arsenal provides a promising foundation for the development of novel, safer, and more effective preventive and therapeutic strategies.
