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). In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Category: dioxole).

(2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Category: dioxole

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.

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).

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.

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%.

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.

The aim of the present work was focused on optimizing the hydrothermal liquefaction (HTL) of Spirulina platensis catalyzed by Fe₃O₄ nanostructures to enhance the bio-oil yield and quality of bio-oil using response surface methodol. (RSM). The structural morphol. and crystalline nature of the synthesized catalyst was determined using a scanning electron microscope (SEM), high resolution transmission electron microscopy (HR-TEM) and X-ray powder diffraction (XRD). Three of the vital reaction parameters such as temperature, holding time and catalyst dosage were optimized through central composite design. A maximum bio-oil yield of 32.33% was observed for the high temperature at 320°C, 0.75 g of catalyst dosage and 37 min of resident time. The maximum conversion was found at a lower temperature of 272°C, the bio-oil yield of 27.66% was obtained with 0.45 g of catalyst dosage and 24 min of holding time which is an energy efficient optimum condition. The maximum bio-oil yield was influenced at a lower temperature due to the high catalytic activity. While compared to higher temperatures were not much influence was observed It clearly states that the catalyst dosage playing a critical role in the lower temperature HTL reaction. GC-MS and FT-IR anal. of the produced bio-oil exhibits significant characteristics for biofuel applications. The Fe₃O₄ catalyst was recyclable for up to eight repeated cycles and constant bio-oil yield for the last four cycles. It shows the excellent reproduction ability towards HTL of Spirulina sp.

Comprehensive Comparison of Two Color Varieties of Perillae Folium by GC-MS-Based Metabolomic Approach was written by Chen, Jiabao;Zhang, Dan;Wang, Qian;Yang, Aitong;Zheng, Yuguang;Wang, Lei. And the article was included in Molecules in 2022.Application of 607-91-0 This article mentions the following:

Perillae Folium (PF), the leaf of Perilla frutescens (L.) Britt, is extensively used as culinary vegetable in many countries. It can be divided into two major varietal forms based on leaf color variation, including purple PF (Perilla frutescens var. arguta) and green PF (P. frutescens var. frutescens). The aroma of purple and green PF is discrepant. To figure out the divergence of chem. composition in purple and green PF, gas chromatog.-tandem mass spectrometry (GC-MS) was applied to analyze compounds in purple and green PF. A total of 54 compounds were identified and relatively quantified. Multivariate statistical methods, including principal component anal. (PCA), orthogonal partial least-squares discrimination anal. (OPLS-DA) and clustering anal. (CA), were used to screen the chem. markers for discrimination of purple and green PF. Seven compounds that accumulated discrepantly in green and purple PF were characterized as chem. markers for the discrimination of the purple and green PF. Among these 7 marker compounds, limonene, shisool and perillaldehyde that from the same branch of the terpenoid biosynthetic pathway were with relatively higher contents in purple PF, while perilla ketone, isoegomaketone, tocopheryl and squalene on other branch pathways were higher in green PF. The results of the present study are expected to provide theor. support for the development and utilization of PF resources.
