Cassano, Valéria; Machín-Sánchez, María; Neto, Ana I.; Oliveira, Mariana C.; Sentíes, Abel; Díaz-Larrea, Jhoana; Gil-Rodríguez, María C.10th International Phycological Congress, Orlando, Florida, USA, 4-10 de agosto 2013. ; The diversity of the Laurencia complex is being assessed in tropical and subtropical Atlantic by an international cooperation project involving Brazil, Mexico, Spain (Canary Islands), Portugal (Azores and Madeira) and USA (Florida) on the base of molecular data allied to a detailed morphological study of species. The divers...

Machín-Sánchez, María; Hernández-Ferrer, M.; Le Gall, Line; Neto, Ana I.; Cassano, Valéria; Sentíes, Abel; Fujii, Mutue T.; Díaz-Larrea, JhoanaXIX Simposio de Botánica Criptogámica, Las Palmas de Gran Canaria, 24-28 de junio de 2013. ; Basado en análisis morfológicos y moleculares, en la actualidad el complejo Laurencia (Rhodophyta, Ceramiales) incluye seis géneros (Chondrophycus, Laurencia, Laurenciella, Osmundea, Palisada y Yuzurua). El objetivo principal de este estudio preliminar es valorar a nivel molecular la posible existencia de un nuevo géne...

Machín-Sánchez, María; Hernández-Ferrer, M.; Le Gall, Line; Neto, Ana I.; Cassano, Valéria; Sentíes, Abel; Fujii, Mutue T.; Díaz-Larrea, Jhoana10th International Phycological Congress, Orlando, Florida, USA, 4-10 de agosto 2013. ; Our aim was to investigate the diversity of the Laurencia complex in the Azores, Madeira, Salvagens and Canary Islands, Atlantic oceanic archipelagos, which belong to the same ecoregion, Lusitanian province of the Macaronesian region. We assessed the species limits among members of the complex using DNA barcode data (partia...

Search for cytotoxic agents in multiple Laurencia complex seaweed species (Cera...
Stein,Erika M.; Andreguetti,Daniel X.; Rocha,Cleidiane S.; Fujii,Mutue T.; Baptista,Mauricio S.; Colepicolo,Pio; Indig,Guilherme L.The development of new anti-cancer drugs of algal origin represents one of the least explored frontiers in medicinal chemistry. In this regard, the diversity of micro- and macroalgae found in Brazilian coastal waters can be viewed as a largely untapped natural resource. In this report, we describe a comparative study on the cytotoxic properties of extracts obtained from the Laurencia complex: Laurencia aldingen...
Sesquiterpenes from the essential oil of Laurencia dendroidea (Ceramiales, Rhod...
Gressler,Vanessa; Stein,Érika M.; Dörr,Fabiane; Fujii,Mutue T.; Colepicolo,Pio; Pinto,ErnaniTwo known sesquiterpenes (1R*,2S*,3R*,5S*,8S*,9R*)-2,3,5,9-tetramethyltricyclo[6.3.0.0(1,5)]undecan-2-ol and (1S*,2S*,3S*,5S*,8S*,9S*)-2,3,5,9-tetramethyltricyclo-[6.3.0.0(1,5)]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 Candida albicans,...
Screening for antifungal activities of extracts of the brazilian seaweed genus ...
Stein,Erika M.; Colepicolo,Pio; Afonso,Felipe A. K.; Fujii,Mutue T.The resistance of pathogens to commonly used antibiotics has enhanced morbidity and mortality and has triggered the search for new drugs. Several species of the red alga genus Laurencia are very interesting candidates as potential sources of natural products with pharmaceutical activity because they are known to produce a wide range of chemically interesting halogenated secondary metabolites. This is an initial...
Overview of the taxonomy and of the major secondary metabolites and their biolo...
Fujii,Mutue T.; Cassano,Valéria; Stein,Érika M.; Carvalho,Luciana R.In Brazil, the Laurencia complex is represented by twenty taxa: Laurencia s.s. with twelve species, Palisada with four species (including Chondrophycus furcatus now that the proposal of its transference to Palisada is in process), and Osmundea and Yuzurua with two species each. The majority of the Brazilian species of the Laurencia complex have been phylogenetically analyzed by 54 rbcL sequences, including five...
Reavaliação das características morfológicas e suas implicações taxonômicas no ...
Guimarães,Silvia M.P.B.; Fujii,Mutue T.; Pupo,Diclá; Yokoya,Nair S.O gênero Polysiphonia Grev. tem uma circunscrição ampla e é heterogêneo em características vegetativas e reprodutivas. O presente trabalho visa o estudo detalhado e a reavaliação das espécies de Polysiphonia sensu lato que ocorrem nos Estados do Espírito Santo e São Paulo, tendo em vista os critérios taxonômicos recentes, que levaram à subdivisão do gêneroem Polysiphonia e Neosiphonia M.-S.
