Report of in vitro antileishmanial properties of Iberian macroalgae
Bruno De Sousa, Carolina; Lago, Joao Henrique G.; Macridachis, Jorge; Oliveira, Marta; Fonseca Brito, Luis; Vizetto-Duarte, Catarina; Florindo, ClaudiaHere is reported the anti Leishmania infantum activity of 48 hexane, CH2Cl2 and MeOH extracts from 16 macroalgae collected on the Iberian Coast. Seven hexane and CH2Cl2 Cystoseira baccata, Cystoseira barbata, Cystoseira tamariscifolia, Cystoseira usneoides, Dictyota spiralis and Plocamium cartilagineum extracts were active towards promastigotes (IC50 29.8-101.8 mu g/mL) inducing strong morphological alterations...
Proximate biochemical composition and mineral content of edible species from th...
Vizetto-Duarte, C; Custódio, Luísa; Barreira, Luísa; da Silva, Manuela Moreira; Rauter, Amelia P.; Albericio, Fernando; Varela, J.Macroalgae are valuable resources for human consumption in many countries. This work reports for the first time a comparative evaluation of the nutritional properties of five edible macroalgae from the genus Cystoseira, namely C. humilis, C. tamariscifolia, C. nodicaulis, C. compressa and C. baccata. For this purpose, their proximate composition was determined in terms of moisture, ash, and total contents of pr...
Isololiolide, a carotenoid metabolite isolated from the brown alga Cystoseira t...
Vizetto-Duarte, C; Custódio, Luísa; Gangadhar, Katkam N.; Lago, João Henrique G.; Dias, Catarina; Matos, Ana Marta; Neng, NunoBackground: Brown macroalgae have attracted attention because they display a wide range of biological activities, including antitumoral properties. In this study we isolated isololiolide from Cystoseira tamariscifolia for the first time.Purpose: To examine the therapeutical potential of isololiolide against tumor cell lines.Methods/Study design: The structure of the compound was established and confirmed by 1D ...
A comparative evaluation of biological activities and bioactive compounds of th...
Custódio, Luísa; Laukaityte, Simona; Engelen, Aschwin; Rodrigues, Maria Joao; Pereira, Hugo; Vizetto-Duarte, C; Barreira, Luísa; Rodriguez, HortensiaThis work assessed the antioxidant potential, acetylcholinesterase (AChE) inhibition and the in vitro cytotoxic activity of extracts of the seagrasses Zostera marina and Zostera noltei collected from southern Portugal. The total phenolic contents (TPCs), the rosmarinic acid (RA) concentration (HPLC/DAD) and the fatty acid (FA) profile (GC/MS) are also described. Z. marina had the highest TPC, radical scavenging...
