Marine algae are producers of many economically important compounds which have been mainly used in the nutraceutical, pharmaceutical, and cosmetic industries. The biological activities of marine algae (i.e., antibacterial, antifungal, antitumoral, antiviral, antiprotozoal) have been studied for many years. Many studies have been carried out in the Mediterranean coasts in order to find natural compounds from marine macroalgae. This chapter is mostly focused on the biological activities of marine macroalgae extracts from the eastern Mediterranean Sea. Several soluble extracts of the marine macroalgae were assessed against parasitic protozoa (i.e., Plasmodium falciparum, and Leishmania infantum), and pathogenic microbes (gram positive and gram negative), and were also tested for cytotoxic and acethylcholinesterase inhibitory activities, in vitro. © 2022 Elsevier B.V.EnglishBook chapter10.1016/B978-0-12-823944-5.00018-1
