The red alga of the genus Laurencia is known as an endless source of metabolites. The main substances produced are sesquiterpenes, diterpenes, triterpenes and acetogenins. Many studies reveal that these metabolites are active, especially cytotoxic and antibacterial. There are few other studies that describe the antiparasital, antifungal and antiviral actions of the metabolites produced by the alga of the genus Laurencia. The results observed in some studies suggest that these metabolites may be used in the future as drugs or lead compounds as antitumoral and/or antibacterial agents. Many metabolites have not been submitted to pharmacological studies which still represents an area to be explored.
