cycloartocarpin/パンノキ属

BACKGROUND Preparations from Artocarpus heterophyllus Lam. (Moraceae) heartwoods are used in the traditional folk medicine for the treatment of inflammation, malarial fever, and to prevent bacterial and fungal infections. OBJECTIVE The objective of this study was to isolate pure antibacterial

Two new prenylated flavonoids, 4',5-dihydroxy-6,7-(2,2-dimethylpyrano)-2'-methoxy-8-γ,γ-dimethylallylflavone 1 and 3'-hydroxycycloartocarpin 2 along with six known flavonoids, 5,7-dihydroxy-4'-methoxy-8-prenylflavanone 3, isobavachalcone 4, pyranocycloartobiloxanthone A 5, artocarpin 6, chaplashin 7

A new oxepinoflavone, artoindonesianin E1 (1), was isolated from the wood of Artocarpus elasticus, along with four known prenylated flavones: artocarpin (2), cycloartocarpin (3), cudraflavones A (4) and C (5). The structure of the new compound was identified by spectroscopic methods. Upon cytotoxic

Six prenylated flavones, including one new compound, were isolated and identified from the stem bark extracts of Artocarpus altilis. The new prenylated flavone hydroxyartocarpin (1) was characterized as 3-(gamma,gamma-dimethylallyl)-6-isopentenyl-5,8,2',4'-tetrahydroxy-7-methoxyflavone and the known

A new prenylated chalcone, 3' ',3' '-dimethylpyrano[3',4']2,4,2'-trihydroxychalcone (1), was isolated from the heartwood of Artocarpus communis. Two flavonoid derivatives, (-)-cycloartocarpin (9) and (-)-cudraflavone A (10), were isolated as new isomers. In addition, eight known flavonoids,

Eight compounds including, phenyl-beta-naphthylamine (1), isocyclomorusin (2), cycloartocarpin (3), artocarpin (4), norartocarpetin (5), cudraflavone C (6), albanin A (7), and resveratrol (8) were isolated from the roots of Artocarpus gomezianus. Compounds 5 and 8 exhibited potent tyrosinase

A new furanoflavone, 7-(2,4-dihydroxyphenyl)-4-hydroxy-2-(2-hydroxy propan-2-yl)-2, 3-dihydrofuro(3, 2-g)chromen-5-one (artocarpfuranol, 1), together with 14 known compounds, dihydromorin (2), steppogenin (3), norartocarpetin (4), artocarpanone (5), artocarpesin (6), artocarpin (7), cycloartocarpin

The heartwood of Artocarpus gomezianus was investigated for anti-herpetic principles. During the course of the separation, a new compound, artogomezianone (1), was isolated, along with the known compounds cycloartocarpin (2), isocyclomorusin (3), artocarpin (4), norcycloartocarpin (5),
