A new labdane diterpene from Vitex negundo.
CONTEXT Vitex negundo Linn. (Verbenaceae) seeds are pepper substitute and occasionally used as a condiment for edible purposes. The seeds also find use for analgesia, sedation, rheumatism and joint inflammation in folk medicine. OBJECTIVE To isolate and characterize bioactive constituents from V. negundo seeds. MATERIALS AND METHODS The ethanol extract of V. negundo seeds was subjected to r...
متن کاملA new labdane diterpene from the flowers of Solidago canadensis.
A new labdane diterpene, 9alpha,16xi-dihydroxy-6-oxo-7,13-labdadien-15,16-olide (solicanolide, 1) and six known compounds identified as quercetin (2), 3-O-caffeoylquinic acid (3, neochlorogenic acid), 5-O-caffeoylquinic acid (4, chlorogenic acid), 4,5-di-O-caffeoylquinic acid (5), 3,5-di-O-caffeoylquinic acid (6) and 3,4-di-O-caffeoylquinic acid (7) were isolated from the flowers of Solidago ca...

Culturas do fungo Fusarium graminearum sob agitação na presença do diterpeno ácido cupréssico [ácido 13-hidróxi-(17),14-labdadien-19-óico], obtido de Araucarea angustifolia elegans, produziram quatro derivados diterpênicos hidroxilados os quais foram identificados por métodos químicos e físicos como sendo os ácidos 3 ,13-diidróxi-8(17),14-labdadien-19-óico, 7 ,13-diidróxi-8(17),14labdadien-19-ó...
متن کاملIdentification and Characterization of Bacterial Diterpene Cyclases that Synthesize the Cembrane Skeleton
Digging up skeletons: We report the identification and the functional characterization of two terpene cyclases (DtcycA and DtcycB) that were mined from the genome of Streptomyces sp. SANK 60404. DtcycA and DtcycB are novel bacterial diterpene cyclases for the synthesis of the cembrane skeleton.
متن کاملcis or trans with class II diterpene cyclases.
Isoprenoid precursors readily undergo (poly)cyclization in electrophilic reaction cascades, presumably as internal addition of the carbon-carbon double-bonds from neighboring isoprenyl repeats readily forms relatively stable cyclohexyl tertiary carbocation intermediates. This hypothesis is agnostic regarding alkene configuration (i.e., Z or E). Consistent with this, here it is shown that certai...
