Chapter 22 - A review on marine-based phytochemicals and their application in biomedical research

Abstract

Phytochemicals are involved in specific biological activities, and they are the natural bioactive substances which are derived from phytonutrients (i.e., plant foods). In the field of biomedicine, various phytochemicals may play a protective role against diseases and infections. Phytochemicals like phenolics, alkaloids, terpenes, and organosulfides are considered secondary metabolites of plant foods. Currently, marine natural products have been recognized as the utmost consequential origin of bioactive substances. Biomedicines include lots of marine-based phytochemical substances associated simultaneously. The diagrammatic dissimilarities of these marine phytochemical substances come from various alteration reactions of the main fluxion. For decades, various phytochemicals have illustrated distinct biomedical and therapeutic effects on the health of human beings such as immune response and antimicrobial. The ongoing headway shows the direction to appreciating the gradual development to recognize narrative dominating properties of marine-based phytochemical substances for biomedical. This chapter summarizes stocking research of marine-based phytochemical substances, which are directly applicable to biomedical as well as therapeutics. All these phytochemicals are stably visualized in various considerable studies (i.e., in vitro, in vivo, and clinical studies) with high potential protectiveness and therapeutics on many infections and diseases that subsequently relate to the biomedicals.
