Cloning of the cytochrome P450 enzyme from Perilla frutescens involved in nothoapiole biosynthesis was written by Baba, Mariko;Ito, Michiho. And the article was included in Journal of Natural Medicines in 2021.Recommanded Product: 6-Allyl-4-methoxybenzo[d][1,3]dioxole This article mentions the following:

Phenylpropanoid volatile components are found in various plants and are useful in medicines, health foods, and fragrances. While the pharmacol. actions and toxicities of these compounds have been investigated, there are few reports of the cloning of genes that encode biosynthetic enzymes involved in substituent formation at diverse positions and numbers Previously, using the expressed sequence tag (EST) libraries of pure perilla strains that have been maintained for over 30 years for their oil type, we characterized the P 450 enzyme that produces an intermediate for dillapiole by adding a hydroxy group to myristicin. In this study, we selected a P 450 enzyme involved in nothoapiole biosynthesis from the EST library. Heterologous expression of this enzyme in yeast showed that it is a hydroxylase that synthesizes an intermediate to produce nothoapiole from apiole and dillapiole. The enzyme has high amino acid sequence similarity with a previously cloned enzyme and is categorized into the CYP71D subfamily. Furthermore, we investigated the presence or absence of essential oil components and intermediates believed to be involved in nothoapiole biosynthesis by component anal. of perilla essential oil using GC-MS to help elucidate the biosynthetic pathway of nothoapiole. Only a small number of plant species contain nothoapiole as their principal component and thus few studies have reported the biosynthetic genes involved or the drug efficacy and toxicity of nothoapiole. The present study will aid in understanding the biosynthesis of phenylpropanoid volatile compounds, thereby contributing to further research on potentially useful compounds such as nothoapiole. In the experiment, the researchers used many compounds, for example, 6-Allyl-4-methoxybenzo[d][1,3]dioxole (cas: 607-91-0Recommanded Product: 6-Allyl-4-methoxybenzo[d][1,3]dioxole).

Selective fluorescence labeling of myristicin using Mizoroki-Heck coupling reaction. Application to nutmeg powder, oil, and human plasma samples was written by Fukuda, Takayuki;Iwata, Hikaru;Kishikawa, Naoya;El-Maghrabey, Mahmoud H.;Ohyama, Kaname;Kawakami, Shigeru;Wada, Mitsuhiro;Kuroda, Naotaka. And the article was included in Journal of Chromatography A in 2022.Related Products of 607-91-0 This article mentions the following:

Myristicin [5-allyl-1-methoxy-2,3-(methylenedioxy)benzene] is the major constituent of the seasoning nutmeg oil and powder. Sometimes myristicin is abused via its ingestion at high doses to cause hallucination. In these high doses, myristicin could cause severe adverse health effects, including convulsion, delirium, and palpitation. Hence there is a strong need for a sensitive method for its anal., such as fluorescence determination Myristicin has a very weak fluorescence and also lacks derivatizable groups like the carboxylic, hydroxyl, or amino group in its structure, which makes its fluorescence derivatization challenging. In this research, we developed a fluorescence labeling method for myristicin based on the Mizoroki-Heck coupling reaction of its terminal alkene with a fluorescent aryl iodide derivative, 4-(4,5-diphenyl-1H-imidazol-2-yl)iodobenzene (DIB-I). Then, we developed an HPLC fluorescence detection method for the determination of myristicin utilizing this labeling reaction. The developed method showed a good linear response for myristicin (r = 0.995) in the range of 0.01-10 μmol/L with excellent sensitivity down to the detection limit of 2.9 nmol/L (9.6 fmol/injection). Finally, the developed method could be successfully applied to determine myristicin content in nutmeg powder, oil samples, and human plasma with simple extraction methods and good recoveries ranging from 89.3 to 106%.

Synthesis of Trisaccharides by Hetero-Diels-Alder Welding of Two Monosaccharide Units was written by Himanen, Jatta A.;Pihko, Petri M.. And the article was included in European Journal of Organic Chemistry in 2012.SDS of cas: 171086-52-5 This article mentions the following:

A new strategy for the synthesis of di- and trisaccharides based on the de novo synthesis of the linking saccharide unit is presented. In this strategy, functionalized monosaccharide building blocks already incorporating the glycosidic linkages are welded together using a metal-catalyzed hetero-Diels-Alder (HDA) reaction to generate a new monosaccharide unit between them. The highest yields and selectivities in the HDA reaction were obtained by using chiral Schiff base chromium complexes. Disaccharide products were accessible by reaction of Danishefsky’s diene with acetyl- and benzyl-protected galactoside aldehydes. For the synthesis of trisaccharide products, acetyl-protected glucose or galactose-derived dienes were fused with monosaccharide-derived aldehydes using chromium catalysts for the HDA reaction. The desired trisaccharide products were obtained in moderate to good yields with excellent stereoselectivity. The central pyranulose-ring generated in the process possessed an L-cis-enulose configuration according to NMR spectroscopy and modeling studies. In the experiment, the researchers used many compounds, for example, ((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(di(naphthalen-1-yl)methanol) (cas: 171086-52-5SDS of cas: 171086-52-5).

AMPA receptor activation potentiated by the AMPA modulator 1-BCP is toxic to cultured rat hippocampal neurons was written by Yamada, Kelvin A.. And the article was included in Neuroscience Letters in 1998.Application In Synthesis of Benzo[d][1,3]dioxol-5-yl(piperidin-1-yl)methanone This article mentions the following:

The benzoylpiperidine 1-(1,3-benzodioxol-5-ylcarbonyl)-piperidine (1-BCP), and related compounds, potentiate α-amino-3-hydroxy-5-methyl-4-isoxazole proprionic acidergic (AMPAergic) synaptic currents in central neurons, and improve performance of rodents and humans on learning and memory tasks. Their physiol. actions are similar but not identical to thiazides, which also enhance AMPAergic synaptic responses and improve performance of rats in water-maze and passive-avoidance tests. Thiazides also dramatically increase AMPA receptor-mediated neuronal death in vitro and in vivo. Here it was evaluated whether 1-BCP potentiated AMPA receptor-mediated excitotoxicity in hippocampal neuron cultures. Glutamate + MK 801 (to block NMDA receptors) + 1 mM 1-BCP produced neuronal death that was reversed by 10 μM 2,3-dihydroxy-6-nitro-7-sulfamoyl-benzo(F)quinoxaline (NBQX), a selective AMPA receptor antagonist. Thus, 1-BCP and drugs with similar activities can facilitate AMPA receptor-mediated excitotoxicity.

Functional poly(carbonate-co-ether) synthesis from glycidyl methacrylate/CO₂ copolymerization catalyzed by Zn-Co(III) double metal cyanide complex catalyst was written by Wei, Ren-Jian;Zhang, Xing-Hong;Zhang, Ying-Ying;Du, Bin-Yang;Fan, Zhi-Qiang;Qi, Guo-Rong. And the article was included in RSC Advances in 2014.Category: dioxole This article mentions the following:

Polycarbonates with pendant functional groups have attracted much attention due to their capability for further chem. modification and post-polymerization This work describes the synthesis of a poly(carbonate-co-ether) with massive pendant acrylate groups from the copolymerization of glycidyl methacrylate (GMA) with carbon dioxide (CO₂), using a nanolamellar zinc-cobalt double metal cyanide complex (Zn-Co(III) DMCC) catalyst. The carbonate linkage content (F_CO2) of the poly(carbonate-co-ether) could be varied from 42.2 to 68.0% by changing the polymerization conditions. Of importance, 4-methoxyphenol was applied for regulating the copolymerization It could not only act as an inhibitor for completely depressing the self-polymerization of GMA via free radical polymerization of the double bond, but also modulate the mol. weight of the resultant copolymers. The obtained copolymer had two terminal hydroxyl groups, which were confirmed by the electrospray ionization-tandem mass spectrometry (ESI-MS) technique. A new thermoset with high glass transition temperature (T_g: 105 or 120 °C) and massive carbonate units as well as hydroxyl (or carboxylic) groups was prepared by the curing reaction of the GMA-CO₂ copolymer with allyl alc. or acrylic acid in the presence of 2,2′-azobisisobutyronitrile (AIBN).

Easy α-alkylation of ketones with alcohols through a hydrogen autotransfer process catalyzed by RuCl₂(DMSO)₄ was written by Martinez, Ricardo;Ramon, Diego J.;Yus, Miguel. And the article was included in Tetrahedron in 2006.Application of 28657-75-2 This article mentions the following:

The electrophilic α-alkylation of ketones with alcs. is accomplished by a hydrogen autotransfer process catalyzed by RuCl₂(DMSO)₄. The reaction can produce either simple alkylated ketones or α,β-unsaturated ketones just by choosing the appropriate starting ketones (Me ketones or bicyclic methylenic ketones, resp.), as well as quinolines (by using 2-aminobenzyl alc. derivatives) or the corresponding alc. derivatives by the addition of an extra equivalent of the initial alc. In the last case, after the above alkylation process reduction of the carbonyl compound takes place. A mechanistic study seems to indicate that the process goes through the oxidation of the alcs. with ruthenium (after a previous deprotonation) to yield the corresponding aldehyde and a ruthenium hydride intermediate. In turn, the aldehyde suffers a classical aldol reaction with the starting ketone to form the α,β-unsaturated ketone, which finally is reduced through a Michael-type addition by the aforementioned ruthenium hydride intermediate. In the experiment, the researchers used many compounds, for example, 1-(6-Aminobenzo[d][1,3]dioxol-5-yl)ethanone (cas: 28657-75-2Application of 28657-75-2).

The effect of grafting density and side chain length on the conformation of PEG grafted bottlebrush polymers was written by Xiao, Lifen;Li, Jie;Peng, Gang;Huang, Geng. And the article was included in Reactive & Functional Polymers in 2020.Quality Control of (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol This article mentions the following:

PEG grafted polymers are a kind of promising materials, and widely applied in polymer electrolytes, lubricants, biotechnol. and biomedical science. While up to now, systematical researches of the relationship between architecture and conformation of PEG grafted polymers are very rare. Here, we efficiently and successfully prepared a series of PEG grafted polymers with different grafting d., and side chain length by combining ring-opening metathesis polymerization (ROMP) and Copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, and then characterized the conformations of the synthesized bottlebrush polymers by AFM technique. The AFM images showed that all the polymers P(NB-alkyne)₄₀₀-g-PEG with low grafting d. were spherical morphol., while the polymers P(NB-2alkyne)₄₀₀-g-PEG and P(NB-4alkyne)₃₉₄-g-PEG presented cylindrical morphol., which indicated that only grafting d. could determine the shape of the prepared PNB-g-PEG bottlebrush polymers. While, the side chain length could affect the size of prepared PEG grafted bottlebrush polymers.
