Sesquiterpenes from the essential oil of Laurencia dendroidea (Ceramiales, Rhodophyta): isolation, biological activities and distribution among seaweeds
Two known sesquiterpenes (1R*,2S*,3R*,5S*,8S*,9R*)-2,3,5,9tetramethyltricyclo[6.3.0.01,5]undecan-2-ol and (1S*,2S*,3S*,5S*,8S*,9S*)2,3,5,9-tetramethyltricyclo-[6.3.0.01,5]undecan-2-ol were isolated for the first time from the essential oil of the red seaweed Laurencia dendroidea collected in the Brazilian coast. These compounds were not active against eight bacteria strains and the yeast Candid...
متن کاملIsolation, Characterization and Antiproliferative Activity of New Metabolites from the South African Endemic Red Algal Species Laurencia alfredensis.
The marine red algae of the genus Laurencia have been widely studied for their structurally diverse and biologically active secondary metabolites. We report here the natural product investigation of the organic extract of a newly identified South African endemic species, Laurencia alfredensis. A sequence of column chromatography, preparative TLC and normal phase HPLC resulted in the isolation o...
متن کاملPhenolic compounds as chemical markers of low taxonomic levels in the marine algal genus Laurencia in the Persian Gulf
The genus Laurencia(Rhodomelaceae), a complex group, has 285 species and infraspecific names. Identification and taxonomy of these taxa, mainly has been based on flexible morphological characters which have led to a complicated taxonomy in this group. Nowadays, taxonomical study of this group has changed a lot by using reproductive characters, anatomical differences and modern...
متن کاملCloning and Functional Characterization of Cycloartenol Synthase from the Red Seaweed Laurencia dendroidea
The red seaweed Laurencia dendroidea belongs to the Rhodophyta, a phylum of eukaryotic algae that is widely distributed across the oceans and that constitute an important source of bioactive specialized metabolites. Laurencia species have been studied since 1950 and were found to contain a plethora of specialized metabolites, mainly halogenated sesquiterpenes, diterpenes and triterpenes that po...
متن کاملNew Insights on the Terpenome of the Red Seaweed Laurencia dendroidea (Florideophyceae, Rhodophyta)
The red seaweeds belonging to the genus Laurencia are well known as halogenated secondary metabolites producers, mainly terpenoids and acetogennins. Several of these chemicals exhibit important ecological roles and biotechnological applications. However, knowledge regarding the genes involved in the biosynthesis of these compounds is still very limited. We detected 20 different genes involved i...
