Isolation of the (+)-Pinoresinol-Mineralizing Pseudomonas sp. Strain SG-MS2 and Elucidation of Its Catabolic Pathway.
    Applied and environmental microbiology, 2018, 02-15, Volume: 84, Issue:4

    Pinoresinol is a dimer of two β-β'-linked coniferyl alcohol molecules. It is both a plant defense molecule synthesized through the shikimic acid pathway and a representative of several β-β-linked dimers produced during the microbial degradation of lignin in dead plant material. Until now, little has been known about the bacterial catabolism of such dimers. Here we report the isolation of the efficient (+)-pinoresinol-mineralizing

Three unusual sesquineolignans from Alpinia conchigera.
    Journal of Asian natural products research, 2013, Volume: 15, Issue:8

    Three unusual sesquineolignans conchignans A, B, and C, together with two known compounds vanillin and phloroglucinol, were isolated from the whole plants of Alpinia conchigera. Their structures were established by spectroscopic analysis, including 2D NMR spectroscopic techniques.

Simiranes A and B: erythroxylanes diterpenes and other compounds from Simira eliezeriana (Rubiaceae).
    Natural product research, 2011, Volume: 25, Issue:18

    The first phytochemical study of Simira eliezeriana Peixoto (Rubiaceae) allowed the isolation and structural determination of two new diterpenes named simirane A [(5R,6R,8R,9R,10S,11S,13S)-6β,11β-dihydroxy-2,4(18),15-erythroxylatrien-1-one] (1) and simirane B [(5S,8R,9R,10S,11S,13S)-11β-hydroxy-2,4(18),15-erythroxylatrien-1-one] (2), together with seven known compounds: sitosterol (3), stigmasterol (4), campesterol (5), coniferaldehyde (6), vanillin (7), pinoresinol (8) and harman (9) from the bark of the plant. The structures of the compounds were established on the basis of spectroscopic methods, including 1-D and 2-D NMR, HRESI-MS and CD analysis and comparisons with available literature data of known compounds.

Chemical constituents from the leaves of Machilus zuihoensis Hayata var. mushaensis (Lu) Y.C. Liu.
    Natural product research, 2009, Volume: 23, Issue:9

    One new lignan, machilolin-A (1), was isolated from the leaves of Machilus zuihoensis Hayata var. mushaensis (Lu) Y. C. Liu (Lauraceae), together with three known compounds, vanillin (2), beta-sitosterol (3) and stigmasterol (4). The structure of 1 was elucidated based on chemical analysis and spectral methods (IR, 1D and 2D NMR, HR-FAB-MS, EI-MS).

Antifungal synergistic effect of scopoletin, a hydroxycoumarin isolated from Melia azedarach L. fruits.
    Journal of agricultural and food chemistry, 2005, Apr-20, Volume: 53, Issue:8

    In the continuous search for antifungal compounds from plants, the hydroxycoumarin scopoletin (1) was isolated from seed kernels of Melia azedarach L. from which three other compounds, vanillin (2), 4-hydroxy-3-methoxycinnamaldehyde (3), and (+/-) pinoresinol (4), have also been isolated. Guided fractionation through autobiography on TLC using Fusarium verticillioides (Saccardo) Nirenberg as test organism led to the isolation of 1, which exhibited a minimum inhibitory concentration (MIC) of 1.50 mg/mL in the microbroth dilution method. Despite its own weak activity, when the coumarin was combined with the above-mentioned compounds, a strong enhancement of the antifungal effect was observed, even showing a complete inhibition in the growth of the pathogen when 1 was added at a concentration of up to 5% of its MIC value. The same level of effectiveness was observed when the synthetic antifungal agents Mancozeb and Carboxin were each combined with compounds 1-4, in which cases it became possible to decrease the effective concentrations of these commercial compounds by up to 2.5 and 3%, respectively.

Cytotoxic constituents of roots of Chaerophyllum hirsutum.
    Journal of natural products, 2004, Volume: 67, Issue:9

    Two new lignan derivatives (1 and 2), along with the known scopoletin (3), methyl caffeate (4), falcarindiol (5), 3,5-dicaffeoylquinic acid, 3,5-dicaffeoylquinic methyl ester, chlorogenic acid, p-hydroxyphenylethyl-trans-ferulate, and vanillin, were isolated from extracts of the roots of Chaerophyllum hirsutum. Structure elucidation of the new compounds was carried out by 1D and 2D NMR experiments and by HRMS analysis. Several of the isolated compounds were tested for their cytotoxic activity against the HL-60, HT-1080, LoVo, and LoVo/Doxo cell lines.

Total synthesis of two naturally occurring bicyclo[3.2.1]octanoid neolignans.
    The Journal of organic chemistry, 2002, Jul-26, Volume: 67, Issue:15

    The first total syntheses of the racemates of naturally occurring macrophyllin-type bicyclo[3.2.1]octanoid neolignans, kadsurenin C 3 and kadsurenin L 4, were accomplished starting from vanillin and resorcinol. The acid-catalyzed rearrangement of hydrobenzofuranoid neolignans into bicyclo[3.2.1]octanoid neolignans was used as the key step.
