Prenylated phenylpropenes from Coleonema pulchellum with antimicrobial activity

Phytochemistry, 1997
The lipophilic root extract of Coleonema pulchellum was analysed and tested for antifungal and antibacterial activity. Eight previously undescribed prenyloxy and geranyloxy phenylpropenes, were isolated as major compounds together with the known evofolin-C as well as the lignans (+/-)-sesamin and (+/-)-prenylpiperitol, the diterpene (-)-pimara-9(11),15-

The monolignol pathway contributes to the biosynthesis of volatile phenylpropenes in flowers

New Phytologist, 2014
Summary Volatile phenylpropenes play important roles in the mediation of interactions between plants and their biotic environments. Their biosynthesis involves the elimination of the oxygen functionality at the side‐chain of monolignols and competes with lignin formation for monolignol utilization.

THE METHOXYMERCURATION OF 2-METHYL-1-PHENYLPROPENE-1

Canadian Journal of Chemistry, 1952
The addition of the elements of methoxymercuric acetate to 2-methyl-1-phenylpropene-1 occurs to give 2-methyl-2-methoxy-1-phenylpropylmercuric acetate. This structure could not be demonstrated by replacement of chloromercuri by halogeno because 2-methyl-1,2-dimethoxy-1-phenylpropane and 2-methyl-2-phenylpropanal or 3-phenylbutanone-2 were obtained ...

Phenylpropenes: Occurrence, Distribution, and Biosynthesis in Fruit

Journal of Agricultural and Food Chemistry, 2016
Phenylpropenes such as eugenol, chavicol, estragole, and anethole contribute to the flavor and aroma of a number of important herbs and spices. They have been shown to function as floral attractants for pollinators and to have antifungal and antimicrobial activities.

Interaction of Selected Phenylpropenes with Dipalmitoylphosphatidylcholine Membrane and Their Relevance to Antibacterial Activity

The Journal of Membrane Biology, 2017
The effect of structurally closely related phenylpropenes (PPs), estragole, anethole, eugenol, and isoeugenol, on the fluidity of dipalmitoyl phosphatidyl choline (DPPC) liposome membrane was investigated by DSC, Raman, and fluorescence anisotropy of 1,6-diphenyl-1,3,5-hexatriene (DPH).

Preparation and chemistry of some 1-Iodo-1-phenylpropenes

Australian Journal of Chemistry, 1971
The oxidation of eight aryl alkyl hydrazones with iodine in the presence of triethylamine gave mixtures of 1-iodo-1-arylpropenes and ketones in yields of 36-73% and 19-43% respectively. Further evidence is presented in favour of an iodocarbonium ion intermediate for this reaction.

Hydrogen-atom attack on 1-phenylpropene at high temperatures

Symposium (International) on Combustion, 1994
The reactions of hydrogen atom with 1-phenylpropene (IPP) have been studied in single-pulse shocktubeexperiments. Contribution from a large number of the possible reactive channels has been observed. The prime channels are the displacement of the methyl group resulting from addition to the olefinic structure and abstraction of a hydrogen from the ...

Investigating the Role of 2-Phenylpropenal in Felbamate-Induced Idiosyncratic Drug Reactions

Chemical Research in Toxicology, 2004
Felbamate (2-phenyl-1,3-propanediol dicarbamate, FBM) can cause aplastic anemia and hepatotoxicity. The mechanism of FBM-induced toxicities is unknown; however, it has been proposed that 2-phenylpropenal, a reactive metabolite of FBM, is responsible.

Adsorption of Natural 3-Phenylpropenic Acids on Cerium Dioxide Surface

Colloid Journal, 2019
It has been shown that adsorption of natural antioxidants, such as 3-phenylpropenic (cinnamic), 3-(4-hydroxyphenyl)propenic (coumaric), and 3-(3-methoxy-4-hydroxyphenyl)propenic (ferulic) acids, on the surface of cerium dioxide is characterized by S-type isotherms, while adsorption of 3-(3,4-dihydroxyphenyl)propenic (caffeic) acid is described by an H ...

Synthesis of N-(1-carboxy-3-phenylpropen-2yl)alanylproline

Chemistry of Heterocyclic Compounds, 1996
A method has been developed for the synthesis of N-(1-carboxy-3-phenylpropen-2-yl)atanylproline by reductive alkylation of alanylproline by the sodium salt of 2-oxo-4-phenylbutenoic acid, using sodium cyanoborohydride and sodium borchydride as reducing agents. The products were separated chromatographically. Under the conditions of the reaction, sodium
