(Centre for Marine Biotechnology and Biomedicine, Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093-0204, USA) Secondary metabolite chemistry of the marine-derived fungus Massarina sp. strain CNT-016. Phytochemistry v. 68(8): p. 1212-1218, 2007 (Eng; 36 ref).

Chemical investigation of the culture broth extracts of the marine-derived fungus Massarina sp. (Lophiostomataceae) (strain CNT-016) has yielded two secondary metabolites, spiromassaritone (1) and massariphenone (2), as well as the previously reported fungal metabolites 6-epi-5'-hydroxy-mycosporulone (3) and enalin A (4). The structures of these compounds were established by a variety of one- and two-dimensional NMR experiments, while the relative configuration of spiromassaritone (1) was determined by X-ray crystallographic methods. The fungal strain was isolated as a sterile mycelium from an ocean mud sample and identified using ITS sequence analysis.

(Department of Biology, American University of Beirut, Beirut, Lebanon) Effects of partial enzymic degradation of sugar beet pectin on oxidative coupling of pectin-linked ferulates in vitro. Phytochemistry v. 68(13): p. 1785-1790, 2007 (Eng; 15 ref).

Pectins were extracted from roots and petioles of sugar beet Beta vulgaris (Chenopodiaceae) and treated with alpha-arabinosidase, 1,4-beta-galactanase or polygalacturonase. They were then cross-linked using hydrogen peroxide and peroxidase. The effects on pectin molecular size were monitored by size-exclusion chromatography and viscometry. A decrease in apparent molecular size was observed after alpha-arabinosidase and polygalacturonase treatment, and all three enzymes caused a decrease in viscosity. The pectins were then cross-linked using hydrogen peroxide and peroxidase, and the effects on dehydrodiferulate formation were monitored by HPLC. Pretreatment with polygalacturonase caused no significant change in subsequent dehydrodiferulate cross-linking, while pretreatment with alpha-arabinosidase caused a slight change in the ratios of the different dehydrodiferulates formed. Pretreatment with 1,4-beta-D-galactanase caused a more significant change in the ratios of the different dehydrodiferulates formed, and also greatly increased the overall recovery of total ferulates (monomers plus dehydrodiferulales), both in root pectin and petiole pectin. The possible effects of polysaccharide microstructure on the dimerisation and further polymerisation of pectin-linked ferulates are discussed.

2010-02-0979 Dayan, F.E.; Duke, S.O.; Sauldubois, A.; Singh, N. ; McCurdy, C.; Cantrell, C. (Agricultural Research Service, Natural Products Utilization Research Unit, P.O. Box 8048, University, MS 38677, USA) p-Hydroxyphenylpyruvate dioxygenase is a herbicidal target site for beta-triketones from Leptospermum scoparium. Phytochemistry v. 68(14): p. 2004-2014, 2007 (Eng; 38 ref).

p-Hydroxyphenylpyruvate dioxygenase (HPPD) is a key enzyme in tyrosine catabolism and is the molecular target site of beta-triketone pharmacophores used to treat hypertyrosinemia in humans. In plants. HPPD is involved in the biosynthesis of prenyl quinones and tocopherols, and is the target site of beta-triketone herbicides. The beta-triketone-rich essential oil of manuka Leptospermum scoparium (Myrtaceae), and its components leptospermone, grandiflorone and flavesone were tested for their activity in whole-plant bioassays and for their potency against HPPD. The achlorophyllous phenotype of developing plants exposed to manuka oil or its purified beta-triketone components was similar to that of plants exposed to the synthetic HPPD inhibitor sulcotrione. The triketone-rich fraction and leptospermone were approximatively 10 times more active than that of the crude manuka oil, with I50 values of 1.45, 0.96 and 11.5 microgmL-1, respectively. The effect of these samples on carotenoid levels was similar. Unlike their synthetic counterpart, steady-state O2 consumption experiments revealed that the natural triketones were competitive reversible inhibitors of HPPD. Dose-response curves against the enzyme activity of HPPD provided apparent I50 values 15.0, 4.02, 3.14, 0.22 microg mL-1 for manuka oil, triketone-rich fraction, leptospermone and gran-diflorone, respectively. Flavesone was not active. Structure activity relationships indicate that the size and lipophilicity of the side-chain affected the potency of the compounds. Computational analysis of the catalytic domain of HPPD indicates that a lipophilic domain proximate from the Fe2+ favors the binding of ligands with lipophilic moieties.

Phytochemistry v. 68(8): p. 1189-1199, 2007 (Eng; 50 ref).

Tyrosinase is a copper-containing monooxygenase that catalyzes melanin synthesis in skin melanocytes. Herein, 13 compounds from the Formosan apple Malus doumeri var. formosana (Rosaceae), an indigenous Taiwanese plant, were isolated and identified. The active constituents were identified as 3-hydroxyphloretin (7) and catechol (9); they exhibited potent hydroxyl radical-scavenging (IC50 values, 0.6 and 1.1 microM) and cellular tyrosinase-reducing activities (IC50 values, 32 and 22 microM) in human epidermal melanocytes. In addition, evaluated the level of several tyrosinase-related proteins by Western blot analysis. In contrast to 3-hydroxyphloretin (7), which showed no effect on the level of these proteins, catechol (9) reduced their activity and the expression of the respective genes, as determined by quantitative real-time PCR. In a kinetic analysis of mushroom tyrosinase, 3-hydroxyphloretin (7) was a competitive inhibitor. These two constituents exhibited metal-coordinating interactions with copper ions in a virtual model of molecular docking with human tyrosinase. Thus, 3-hydroxyphloretin (7) and catechol (9) were the most active constituents from the Formosan apple; they exhibited antioxidant and tyrosinase reducing activities, suggesting their possible use as cosmetic agents.

Phytochemistry v. 68(13): p. 1746-1751, 2007 (Eng; 17 ref).

Biosynthesis of lilac compounds in 'Hortgem Tahi' kiwifruit Actinidia arguta flowers was investigated by treating inflorescences with ds-linalool. The incorporation of the deuterium label into 8-hydroxylinalool, 8-oxolinalool, the lilac aldehydes, alcohols, and alcohol epoxides was followed by GC-MS and enantioselective GC-MS. Both (R)- and (S)-linalool were produced naturally by the flowers, but 8-hydroxylinalool, 8-oxolinalool, and the lilac aldehydes and alcohols occurred predominantly as the (S) and 5'(S)-diastereoisomers, respectively. The enantioselective step in the biosynthesis of the lilac aldehydes and alcohols was concluded to be the oxidation of linalool to (S)-8-hydroxylinalool. In contrast, the lilac alcohol epoxides had a 5'(R):(S) ratio, the same as for linalool, which suggests that either these compounds are not synthesised from the 5'(S)-configured lilac aldehydes and alcohols, or that if indeed they are, then it is by an enantioselective step that favours utilisation of the 5'(R)--configured compounds.

Natural product substances have historically served as the most significant source of new leads for pharmaceutical development. However, with the advent of robotics, bioinformatics, high throughput screening (HTS), molecular biology-biotechnology, combinatorial chemistry, in silico (molecular modeling) and other methodologies, the pharmaceutical industry has largely moved away from plant derived natural products as a source for leads and prospective drug candidates. Can, or will, natural products ever recapture the preeminent position they once held as a foundation for drug discovery and development? The challenges associated with development of natural products as pharmaceuticals are illustrated by the Taxol story. Several misconceptions, which constrain utilization of plant natural products, for discovery and development of pharmaceuticals. are addressed to return natural products to the forefront.

The present investigation describes the effect of the spasmolytic benzylbenzoates 1-9 from Brickellia veronicifolia (Asteraceae) on CaM-using a functional in vitro enzymatic assay. Bovine brain PDE1 was used as a monitoring enzyme. The most active natural inhibitors of the system CaM-PDE1 were benzyl benzoates 3-5, which inhibited the activity of PDE1 in a concentration-dependent manner. In addition, these series of analogs of compound 4, compounds 10a--32a, were prepared and assayed. The benzyl benzoates from the first series, namely 10a-24a, possess no substituents on ring B but different number and position of hydroxyl or methoxy groups in ring A. The second group (25-32a), on the other hand, possesses an A ring identical to that on compound 4, but different substituents in Ring B. The most active compounds were 14a, 15a and 30a. These compounds were two to six times more potent than chlorpromazine, a well known CaM inhibitor. Benzyl benzoates 14a and 15a have methoxyi groups at C-2/C-4 and C-3/C-4 in ring A, respectively; while 30a, in addition to the methoxyi groups at C-2/C-6 of ring A, hold a benzoyloxy moiety at C-3' of ring B. Kinetic studies revealed that compounds 3, 4, 14a, 15a and 30a behave as competitive CaM antagonists.

Phytochemistry v. 68(8): p. 1227-1235, 2007 (Eng; 31 ref).

Lignans in flaxseed are known to be part of a macromolecule in which they are connected through the linker-molecule hydroxy-methyl-glutaric acid (HMGA). In this study, the lignan macromolecule was extracted from flaxseed hulls and degraded to its monomeric constituents by complete saponification. Besides secoisolariciresinol diglucoside (SDG), the phenolic compounds p-coumaric acid glucoside (CouAG) and ferulic acid glucoside (FeAG) were isolated, which was expected based on indications from the literature. Also the flavonoid herbacetin diglucoside (HDG) was found. The presence of HDG was confirmed by NMR following preparative RP-HPLC purification. Also the presence of the three other constituents (CouAG, FeAG and SDG) was confirmed by NMR. To prove that HDG is a substructure of the lignan macromolecule, the macromolecule was fragmented by partial saponification. A fragment consisting of HDG and HMGA was indicated. This fragment was isolated by preparative RP-HPLC and its identity was confirmed by NMR. It is concluded that the flavonoid HDG is a substructure of the lignan macromolecule from flaxseed hulls and that it is incorporated in the macromolecule via the same linker-molecule as SDG.

The composition and dynamics of the principal components of essential oils from roots of 19 introduced species of Heracleum (Apiaceae) were found in order to determine if the data could be used to resolve issues with the species systematics of this genus. The results showed that the essential oil content in roots of various species varied form 0.1 to 1.0 percent. Species of the Pubescentia section had the greatest accumulations. Some species from various sections of the genus have rather similar component compoisitions for essential oils from roots. Esters, terpenes, and sesquiterpenes dominate the essential oil compositions. Species within a single section have similar compositions. Difference between species and sections are quantitative at both the principal level (alpha-pinene, beta-pinene, myrcene, ocimene, octylacetate, trans-alloocimene) and at the level of minor components (octanol, gamma-terpinene, terpinen-4-ol, etc.). The results showed that essential oil from roots of a single species obtained at different vegetation phased also differed in the ratio of components. Certain components such as alpha-and beta-pinene, camphene, myrcene, limonene, ocimene and octylactate were found in all species.

Evidence is presented for the presence of xylogalacturonan (XGA) Arabidopsis thaliana. This evidence was obtained by extraction of pectin from the seeds, root, stem, young leaves and mature leaves of A. thaliana followed by treatment of these pectin extracts with xylogalacturonan hydrolase (XGH). Upon enzymatic treatment, XGA oligosaccharides were primarily produced from pectin extracts obtained from the young and mature leaves and to a lesser extent from those originating from the stem of A. thaliana. The oligosaccharide GalA3Xyl was predominantly formed from these pectin extracts. No XGA oligosaccharides were detected in digests of pectin extracts from the seeds and roots. A low number of XGA oligosaccharides was obtained from pectins of A. thaliana. This indicates a uniform distribution of xylose in XGA from A. thaliana. The predominant production of GalA3Xyl, as well as the release of linear GalA oligosaccharides pointed to a lower degree of xylose substitution in XGA from A. thaliana than in XGA from apple and potato. The estimated amount of XGA accounted for approximately 2.5 percent, 7 percent and 6 percent (w/w) of the total carbohydrate in the pectin fraction of the stem, young leaves and mature leaves, respectively.

(Department of Phytochemistry, China Pharmaceutical University, Nanjing 210009, China) A new decalin derivative from red yeast rice. Journal of Asian Natural Products Research v. 11(9-10): p. 792-795, 2009 (Eng; 10 ref).

Red yeast rice, also called as 'red mold rice' or 'Hongqu', has been used as food and traditional medicine for a long time in China. Red yeast rice could be obtained by the fermentation of rice Oryza sativa with fungi of the genus Monascus purpureus (Monascaceae). A new decalin derivative, monascusic acid A (1), together with a new natural product (2), was isolated from the ethanol extract of red yeast rice. Their structures were elucidated by spectroscopic methods.

Two novel furostanol saponins were isolated from the fresh tubers of Ophiopogon japonicus (Liliaceae). Comprehensive spectroscopic analysis allowed the chemical structures of the compounds to be assigned as (25R)-26-(0-beta-D-glucopyranosyl-(1-2)-beta-D-glucopyranosyl)-22alp ha-hydroxyfurost-5-ene-3-O-beta-D-xylopyranosyl-(1-4)-O-alpha-L-rhamn opyranosyl-(l-2)-beta-D-glucopyranoside (1, ophiopogonin F) and (25R)-26-(O-beta-D-glucopyranosyl-(1 -6)-beta-D-glucopyranosyl)-22alpha-hydroxyfurost-5-ene-3-0-beta-D-xyl opyranosyl-(1- 4)-O-alpha-L- rhamnopyranosyl-(1-2)-beta-D-glucopyranoside (2, ophiopogonin G). The rare furostanol saponins with two glucosyl residues at C-26 position were isolated from the natural source for the first time.
