Abstract
Cancer is a major public health concern, and there are no entirely effective
treatments. Therefore, natural product-based alternative therapies have been suggested
as effective therapeutics against cancer. Marine algae are a promising research tool
considered a natural source of bioactive compounds embedded in marine ecology.
Algae synthesize a vast variety of bioactive compounds, including polysaccharides,
polyphenols, sterols, alkaloids, flavonoids, tannins, proteins, essential fatty acids,
enzymes, vitamins, and carotenoids. These pure compounds are composed of intricate
structures and exhibit a wide array of possible capabilities, including anticancer
potency, in a plethora of in vitro and in vivo settings. Further, these bioactive
constituents derived from seaweeds target crucial molecules that control the
development of cancer. So, this chapter mainly focuses on the anti-cancer properties of
pure compounds isolated from seaweeds and their therapeutic potential against a wide
array of cancer types.
