Interactions betweenAlloxysta brevis (Hymenoptera, Cynipoidea, Alloxystidae) and honeydew-collecting ants: How an aphid hyperparasitoid overcomes ant aggression by chemical defense.

Journal of chemical ecology

Völkl W, Hübner G, Dettner K.
PMID: 24241923
J Chem Ecol. 1994 Nov;20(11):2901-15. doi: 10.1007/BF02098397.

Foraging females of the aphid hyperparasitoidAlloxysta brevis were attacked by honeydew-collecting workers of the antLasius niger at the first encounter. However, ants abandoned their attacks quickly, and foragingA. brevis remained unmolested for a subsequent time interval of approximately 5...

Monoterpenol Oxidative Metabolism: Role in Plant Adaptation and Potential Applications.

Frontiers in plant science

Ilc T, Parage C, Boachon B, Navrot N, Werck-Reichhart D.
PMID: 27200002
Front Plant Sci. 2016 Apr 26;7:509. doi: 10.3389/fpls.2016.00509. eCollection 2016.

Plants use monoterpenols as precursors for the production of functionally and structurally diverse molecules, which are key players in interactions with other organisms such as pollinators, flower visitors, herbivores, fungal, or microbial pathogens. For humans, many of these monoterpenol...

A general approach to iridoids by applying a new Julia olefination and a tandem anion-radical-carbocation crossover reaction.

Organic & biomolecular chemistry

Řehová L, Dračínský M, Jahn U.
PMID: 27714288
Org Biomol Chem. 2016 Oct 12;14(40):9612-9621. doi: 10.1039/c6ob01599a.

A unified, asymmetric approach to the total synthesis of naturally occurring iridoids is presented. The synthesis features a recently discovered ortho → α transmetalation of alkyl aryl sulfone carbanions, thus enabling Julia reactions, by which so far hardly accessible...

Noni juice reduces lipid peroxidation-derived DNA adducts in heavy smokers.

Food science & nutrition

Wang MY, Peng L, Jensen CJ, Deng S, West BJ.
PMID: 24804023
Food Sci Nutr. 2013 Mar;1(2):141-9. doi: 10.1002/fsn3.21. Epub 2013 Jan 07.

Food plants provide important phytochemicals which help improve or maintain health through various biological activities, including antioxidant effects. Cigarette smoke-induced oxidative stress leads to the formation of lipid hydroperoxides (LOOHs) and their decomposition product malondialdehyde (MDA), both of which...

Phylogeny and classification of Oleaceae based on rps16 and trnL-F sequence data.

American journal of botany

Wallander E, Albert VA.
PMID: 11118421
Am J Bot. 2000 Dec;87(12):1827-41.

Phylogenetic relationships among 76 species of Oleaceae, representing all 25 recognized genera of the family, were assessed by a cladistic analysis of DNA sequences from two noncoding chloroplast loci, the rps16 intron and the trnL-F region. Consensus trees from...

Iridoids from Carbohydrates via Pauson-Khand Reaction: Synthesis of Advanced Highly Oxygenated Cyclopentane-Annulated Pyranosides from D-Glucal Derivatives.

The Journal of organic chemistry

Marco-Contelles J, Ruiz-Caro J.
PMID: 11674752
J Org Chem. 1999 Oct 29;64(22):8302-8310. doi: 10.1021/jo991044x.

The Pauson-Khand reaction on suitable 4-oxa-hept-1-en-6-ynes (1, 17) obtained from 3,4,6-tri-O-acetyl-D-glucal gives the cyclopentane-annulated pyranosides (2, 18) that can be efficiently and stereoselectivelly transformed into chiral, advanced, highly oxygenated intermediates (10, 16, 24) for the synthesis of iridoid aglycones.
