ABSTRACT

Marine natural products (NPs) are an eminent source of chemically derived groups which have more vital functions and to be developed efficient therapeutic products. Seaweed or macroalgae is one of the major sources to obtain various bio-therapeutic molecules and it is a multi-billion-dollar industries throughout the worldwide. It is based on farming of edible species for the production of pigments, polysaccharides, phenolic groups, fatty acids, phlorotannins, alkaloids, terpenoids, and halogenated compounds, etc. In the last three decades, the finding of metabolites with biotherapeutic and pharmaceutical activities from macroalgae has increased significantly. In biomedical field, it can be used to treat respiratory weakness, anticoagulant in blood product, stabilizing agents in drugs, lotions, medicinal creams, antidiabetic, antioxidant, and anticancer agent, etc. The biomolecules from seaweeds could be used in cough medicines, especially combat colds, chronic coughs, and bronchitis. New research on the applications of biocidal characteristics of extracted sulfated polysaccharide from seaweeds may block the transmission of the human immunodeficiency virus (HIV), sexually transmitted disease (STD) viruses such as gonorrhea, genital warts and the herpes simplex virus (HSV). This chapter investigates the biopotential pharmaceutical, medicinal, and research applications of these compounds of macroalgae are discussed.
