“…Localisation studies of the related cyclic peptides patellamides A-C suggested that the natural products are distributed throughout the tunic of the ascidian Lissoclinum patella and not located in the Prochloron sp. Rubrolide M, recently isolated from a Spanish collection of the ascidian Synoicum blochmanni, 524 was synthesised using palladium-catalysed coupling methodology. 511 Halocidin was isolated as an antimicrobial peptide (3443 Da) from the hemocytes of the solitary ascidian Halocynthia aurantium.…”

“…1), secondary metabolites produced by marine ascidians [14][15][16][17]. All the synthetic analogues were able to interfere with the chloroplast electron transport chain and the most active compound showed an IC 50 (concentration causing 50% inhibition) value of 1.1 ± 0.2 M, only one order of magnitude higher than that of the commercial herbicide Diuron (0.27 M) [17].…”

“…A condição descrita pelos autores como ideal para a reação de Suzuki em C4 utiliza 20 Rubrolídeos são metabólitos secundários isolados das esponjas Ritterella rubra e Sinoicum blochmanni. 39,45 Estes produtos naturais, apesar de estruturalmente simples, apresentam diversos tipos de atividade biológica importantes, como inibição da proteína fosfatase, citotoxidade contra células humanas cancerosas, além de atuarem como antibióticos. Durante a síntese do rubrolídeo N (59a), Bellina e colaboradores expandiram, para os ácidos fenil-borônicos, a metodologia desenvolvida para a reação de Suzuki com os ácidos alquil-borônicos.…”
