Secondary metabolites from the stems of Engelhardia roxburghiana and their antitubercular activities.
Bioassay-guided fractionation of stems of Engelhardia roxburghiana led to isolation of seven diarylheptanoids and one 1-tetralone, which showed antitubercular activity against Mycobacterium tuberculosis H(37)Rv with MIC values of 72.7 and 70.1μM, respectively.
Secondary metabolites from the roots of Neolitsea daibuensis and their anti-inflammatory activity.
Bioassay-guided fractionation of the roots of Neolitsea daibuensis afforded three new β-carboline alkaloids, daibucarbolines A-C (1-3), three new sesquiterpenoids, daibulactones A and B (4 and 5) and
Secondary Metabolites from the Roots of Beilschmiedia tsangii and Their Anti-Inflammatory Activities
Four new endiandric acid analogues and two new sesquiterpenes were isolated from the roots of Beilschmiedia tsangii (Lauraceae), together with four known compounds, and exhibited moderate iNOS inhibitory activity.
Six new metabolites produced by Colletotrichum aotearoa 09F0161, an endophytic fungus isolated from Bredia oldhamii
This is the first report on isochroman glycoside metabolites (1–4) from the genus Colletotrichum, and the effects of some isolates on the inhibition of nitric oxide (NO) production in lipopolysaccharide-activated murine macrophage RAW2647 cells were evaluated.
Secondary metabolites from the leaves of Neolitsea hiiranensis and the anti-inflammatory activity of some of them.
Among the isolates, hiiranlactones B and D exhibited inhibitory activity against fMLP-induced superoxide production by human neutrophils with IC(50) values of 21.86±3.97 and 25.78±4.77μM, respectively.
Secondary metabolites produced by an endophytic fungus Cordyceps ninchukispora from the seeds of Beilschmiedia erythrophloia Hayata
Abstract Four new amide derivatives, designated as cordycepiamides A–D (1–4), together with 14 known compounds (5–18), were isolated from the EtOAc-soluble fraction of the 95% EtOH extract of
Simultaneous reductive and adsorptive removal of bromate from water using acid-washed zero-valent aluminum (ZVAl)
Abstract Zero valent aluminum (ZVAl), prepared from washing aluminum powder with acids, is employed for the first time to remove bromate from water. With a short acid-washing time ( i.e. , 120 s),
Enhanced photocatalytic reduction of concentrated bromate in the presence of alcohols
Abstract Membrane separation of bromate can continuously treat bromate-containing water; however concentrated bromate solutions would be an inevitable waste which requires proper treatments before
Secondary metabolites from the unripe pulp of Persea americana and their antimycobacterial activities.
Five new fatty alcohol derivatives from the unripe pulp of P. americana showed antimycobacterial activity against Mycobacterium tuberculosis H(37)R(V)in vitro, with MIC values of 24.8, 24.9, and 35.7 μg/ml, respectively.
