Till today, 44 alkaloids were isolated from macroalgae; some of which were reported to induce important pharmacological effects. These alkaloids can be classified under four groups as 2-phenylethylamine, indole, halogenated indole, and 2,7-naphthyridine derivatives, and each group displays a relatively distinguished activity profile. Overall, pharmacological effect spectrum of macroalga alkaloids is wide and includes neuromodulation, neurotransmission, growth regulation, cytotoxicity, angiogenesis, antioxidation as well as antibacterial, antifungal, and larvicidal activities. © Springer-Verlag Berlin Heidelberg 2013.eninfo:eu-repo/semantics/closedAccessAlkaloids; Macroa; PharmacologyBook Chapter1203121610.1007/978-3-642-22144-6_32-s2.0-84908051212N/A
