4-(hidroximetil)-benzenossulfonato de potássio: metabólito inédito isolado da alga marinha Bostrychia tenella (Rhodomelaceae, ceramiales)

Abstract: Recebido em 8/2/08, aceito em 8/4/08, publicado na web em 29/4/08 POTASSIUM 4-(HYDROXYMETHYL)-BENZENOSULFONATE: A NOVEL METABOLITE ISOLATED FROM THE MARINE RED ALGA Bostrychia tenella (RHODOMELACEAE, CERAMIALES). Chemical investigation of the dichloromethane/methanol extract of the marine alga Bostrychia tenella has led to the isolation of two aromatic compounds, the new sulfate metabolite potassium 4-(hydroxymethyl)-benzenosulfonate (1) and the compound 1-methoxyphenethyl alcohol (2), described previously as … Show more

“…However, cryptic species are known to occur in several species complexes of Bostrychia , such as B. tenella , B. radicans , B. moritziana , B. simpliciuscula , B. calliptera and B. intricata [2,3]. Although the genus Bostrychia has recently received attention regarding its phylogeny and evolution, only a few studies have addressed their chemical composition, including reports on the occurrence of fatty acids, amino acids, carbohydrates, polysaccharides, betaines, phenolics, and mycosporine-like amino acids (MAAs) [4,5,6,7,8,9]. Regarding the latter, Bostrychia species have been reported to produce varying quantities of the UV-absorbing compounds mycosporine-glycine, shinorine, porphyra-334, palythine, asterina-330 and palythinol [9,10], however there are no detailed structural reports on the betaines.…”

“…[6][7][8][9] In this context, polysaccharides isolated from Bostrychia montagnei Harvey were characterized 10 while the antiherpetic and anticoagulant activities of these compounds were reported by Duarte. 11 Moreover, two aromatic compounds were isolated from the alga Bostrychia tenella, namely, the new sulfated metabolite potassium 4-(hydroxymethyl)-benzenesulfonate and the compound 1-methoxyphenethyl alcohol. 12 However, research regarding the secondary metabolism of Bostrychia species remains scarce in the literature. Against this background, the present study aimed to describe the chemical investigation of red algae B. radicans, yielding the isolation and structural elucidation of 20 compounds, including two amides: N,4-dihydroxy-N-(2'-hydroxyethyl)-benzamide and N,4-dihydroxy-N-(2'-hydroxyethyl)-benzeneacetamide, both of which were isolated for the first time as natural products from the marine environment.…”

“…A investigação química da espécie Bostrychia tenella, resultou no isolamento de duas substâncias aromáticas: a substância inédita 4-(hidroximetil)-benzenossulfonato de potássio (representada na Figura 5), bem como do álcool 1-metoxifeniletílico, descrito previamente como um produto de síntese (FELÍCIO et al, 2008 Diante desta excelente versatilidade quanto ao potencial biológico exibido por este gênero, optou-se por continuar o estudo químico da espécie Bostrychia radicans, no intuito de atribuir e estabelecer esta potencialidade às substâncias produzidas por este organismo.…”
