Christmas gingerbread (Lebkuchen) and Christmas cheer--review of the potential role of mood elevating amphetamine-like compounds formed in vivo and in furno.

J R Idle

Prague medical report, 106(1), 27-38 (2005-07-13)

The typical spices used in winter include nutmeg, cinnamon, clove and anise. These spices contain two groups of chemicals, the allylbenzenes and their isomers, the propenylbenzenes. It was suggested 40 years ago by Alexander Shulgin that these substances act as

Suppression of chemical mutagen-induced SOS response by allylbenzen from Asiasarum heterotropoides in the Salmonella typhimurium TA1535/PSK1002 umu test.

Mitsuo Miyazawa et al.

Natural product research, 19(1), 29-36 (2005-02-11)

A methanol extract from Asiasarum heterotropoides showed a suppressive effect of the SOS-including activity on the mutagen 2-amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ) in the Salmonella typhimurium TA1535/pSK1002 umu test. The methanol extract was re-extracted with chloroform, butanol, and water. The chloroform fraction showed

Simplifying nickel(0) catalysis: an air-stable nickel precatalyst for the internally selective benzylation of terminal alkenes.

Eric A Standley et al.

Journal of the American Chemical Society, 135(4), 1585-1592 (2013-01-16)

The synthesis and characterization of the air-stable nickel(II) complex trans-(PCy(2)Ph)(2)Ni(o-tolyl)Cl is described in conjunction with an investigation of its use for the Mizoroki-Heck-type, room temperature, internally selective coupling of substituted benzyl chlorides with terminal alkenes. This reaction, which employs a

Physiologically based biokinetic (PBBK) model for safrole bioactivation and detoxification in rats.

E Martati et al.

Chemical research in toxicology, 24(6), 818-834 (2011-03-31)

A physiologically based biokinetic (PBBK) model for alkenylbenzene safrole in rats was developed using in vitro metabolic parameters determined using relevant tissue fractions. The performance of the model was evaluated by comparison of the predicted levels of 1,2-dihydroxy-4-allylbenzene and 1'-hydroxysafrole

Synthesis and SAR comparative studies of 2-allyl-4-methoxy-1-alkoxybenzenes as 15-lipoxygenase inhibitors.

Hamid Sadeghian et al.

Journal of enzyme inhibition and medicinal chemistry, 26(2), 238-244 (2010-10-14)

A group of 2-alkoxy-5-methoxyallylbenzene were designed, synthesised and evaluated as potential inhibitors of the soybean 15-lipoxygenase (SLO) on the basis of the eugenol and esteragol structures. Compound 4d showed the best half maximal inhibitory concentration (IC₅₀) for SLO inhibition (IC₅₀ = 5.9 ± 0.6

Nickel-catalyzed Heck-type reactions of benzyl chlorides and simple olefins.

Ryosuke Matsubara et al.

Journal of the American Chemical Society, 133(47), 19020-19023 (2011-11-10)

Nickel-catalyzed intermolecular benzylation and heterobenzylation of unactivated alkenes to provide functionalized allylbenzene derivatives are described. A wide range of both the benzyl chloride and alkene coupling partners are tolerated. In contrast to analogous palladium-catalyzed variants of this process, all reactions

Fast and green microwave-assisted conversion of essential oil allylbenzenes into the corresponding aldehydes via alkene isomerization and subsequent potassium permanganate promoted oxidative alkene group cleavage.

Thi X Thi Luu et al.

Molecules (Basel, Switzerland), 14(9), 3411-3424 (2009-09-29)

Essential oil allylbenzenes from have been converted quickly and efficiently into the corresponding benzaldehydes in good yields by a two-step "green" reaction pathway based on a solventless alkene group isomerization by KF/Al(2)O(3) to form the corresponding 1-arylpropene and a subsequent

Isoeugenol suppression of inducible nitric oxide synthase expression is mediated by down-regulation of NF-kappaB, ERK1/2, and p38 kinase.

Chun Yeon Choi et al.

European journal of pharmacology, 576(1-3), 151-159 (2007-08-19)

Isoeugenol, which is a naturally occurring o-methoxyphenol in a variety of foods and essential oils, is known to have anti-inflammatory effects, although the mechanism is not clear. In the present study, we investigated the effect of isoeugenol on NF-kappaB signaling

Bimetallic Zr,Zr-Hydride Complexes in Zirconocene Catalyzed Alkene Dimerization.

Lyudmila V Parfenova et al.

Molecules (Basel, Switzerland), 25(9) (2020-05-14)

Being valuable precursors in the production of adhesives, lubricants, and other high-performance synthetic compounds, alkene dimers and oligomers can be obtained using homogeneous zirconocene catalytic systems. Further advances in such systems require precise control of their activity and chemoselectivity, increasing

Anti-Markovnikov terminal and gem-olefin hydrosilylation using a κ4-diimine nickel catalyst: selectivity for alkene hydrosilylation over ether C-O bond cleavage.

Christopher L Rock et al.

Dalton transactions (Cambridge, England : 2003), 48(2), 461-467 (2018-11-30)

The phosphine-substituted α-diimine Ni precursor, (Ph2PPrDI)Ni, has been found to catalyze alkene hydrosilylation in the presence of Ph2SiH2 with turnover frequencies of up to 124 h-1 at 25 °C (990 h-1 at 60 °C). Moreover, the selective hydrosilylation of allylic

Mössbauer and electron paramagnetic resonance studies of chloroperoxidase following mechanism-based inactivation with allylbenzene.

P G Debrunner et al.

Proceedings of the National Academy of Sciences of the United States of America, 93(23), 12791-12798 (1996-11-12)

We have used Mössbauer and electron paramagnetic resonance (EPR) spectroscopy to study a heme-N-alkylated derivative of chloroperoxidase (CPO) prepared by mechanism-based inactivation with allylbenzene and hydrogen peroxide. The freshly prepared inactivated enzyme ("green CPO") displayed a nearly pure low-spin ferric
