“…These compounds are mainly isolated from marine microorganisms and phytoplankton, green algae, brown algae, red algae, sponges, cnidarians, bryozoans, molluscs, tunicates, echinoderms, and true mangrove plants [5]. According to their chemical structures, the compounds isolated form marine organisms belong to various classes of compounds, including long-chain polyols and polyethers [6], alkaloids [7 -10], monoterpenoids [11], diterpenoids [12] [13], sesterterpenoids [14 -16], peptides [17] [18], triterpene glycosides [19], gangliosides [20] [21], conotoxins [22 -24], and steroids [25].…”
