Recommanded Product: 99-93-4. I found the field of Energy & Fuels; Engineering very interesting. Saw the article Transformation of Ammonia Fiber Expansion (AFEX) corn stover lignin into microbial lipids by Rhodococcus opacus published in 2019.0, Reprint Addresses Pan, XJ (corresponding author), Univ Wisconsin, Dept Biol Syst Engn, 460 Henry Mall, Madison, WI 53706 USA.. The CAS is 99-93-4. Through research, I have a further understanding and discovery of 4′-Hydroxyacetophenone.

The lignin from AFEX-pretreated corn stover and lignin model compounds were evaluated as the sole carbon source for microbial lipid production by Rhodococcus opacus NRRL B-3311. R. opacus NRRL B-3311 could grow on the AFEX-lignin without pretreatment and accumulate lipids up to 32 mg/L in 72 h with consuming 20% of the total lignin. The lipid produced from lignin had a similar fatty acid compositional profile to those of vegetable oil. Based on the metabolism analysis, R. opacus NRRL B-3311 could depolymerize AFEX-lignin and catabolize the aromatic compounds derived from the lignin. Study using aromatic model compounds found that R. opacus NRRL B-3311 preferably utilized 4-hydroxybenzoic acid as the sole carbon source over glucose, while it could not grow on p-coumaric acid or vanillin.

Background: In continuation of our work, new diazenyl chalcones scaffolds (C-18 to C-27) were efficiently synthesized from substituted acetophenone azo dyes (A-E) by base catalyzed Claisen-Schmidt condensation with different substituted aromatic/heteroaromatic aldehydes. Methodology: The synthesized chalcones were assessed for their in vitro antimicrobial potential towards several pathogenic microbial strains by tube dilution method and further evaluated for antioxidant potential by DPPH assay. These derivatives were also assessed for the cytotoxicity towards the human lung cancer cell line (A549) and normal cell line (HEK) by MTT assay. The most active antimicrobial compounds were docked using Schrodinger v18.1 software with the various potential bacterial receptors to explore the mechanism of interaction. Results: The derivative C-22 exhibited high antibacterial activity with very low MIC (1.95-3.90 mu g ml(-1)) and MBC (3.90-7.81 mu g ml(-1)) values. The derivatives C-23, C-24 and C-27 have demonstrated good antioxidant potential (IC50 = 7-18 mu g ml(-1)) correlated to the ascorbic acid (IC50 = 4.45 mu g ml(-1)). The derivative C-25 had shown comparable cytotoxicity to camptothecin against A549 cell line. The docking studies predicted the bacterial dihydrofolate reductase (PDB ID: 3SRW) and bacterial DNA gyrase (PDB ID: 4ZVI) as the possible targets for most of the active antimicrobial compounds. These derivatives affirmed their safety by presenting less cytotoxicity towards HEK cells. Further the ADME prediction by qikprop module of the Schrodinger proved that these compounds exhibited drug-like attributes. Conclusion: Hence, these compounds have shown their potential as lead for future expansion of novel antimicrobial and cytotoxic drugs.

Lignin transformation to high-value chemicals is key for forthcoming biorefineries. Here, we report efficient delignification of pine wood by oxidative biorefining in aqueous alkali, producing both vanillin and cellulose as valuable end products. Under optimal conditions, viz., 400 rpm, 160 degrees C, 1 h, 7.5 wt % NaOH, and 1 MPa O-2, more than 90% of lignin is converted and fractionated into monophenolics (29 wt % on Kraft lignin basis and vanillin yield is 21.1 wt %) and small oligophenolics (56.7 wt %, average M-w between 300 and 600 Da), next to a pool of small carboxylic acids. Depending on the conditions, a substantial amount of white residue can be formed as a coproduct, comprising 45% yield of 95.5% pure fibrous crystalline cellulose I, or a less pure cellulose residue can be obtained, which is highly reactive toward levulinic and formic acid formation using acid catalysis. Liquor refining by liquid-liquid extraction facilitates thorough identification of the main products by gas chromatography-mass spectrometry (MS), heteronuclear single quantum coherence NMR, electrospray ionization quadrupole time-of-flight mass spectrometry, and gel permeation chromatography. The mass balance shows close to 70% carbon efficiency of biomass conversion into useful products. Surprisingly, agitation speed, in addition to base concentration, temperature, and reaction time, is a crucial parameter to overcome deeper oxidation/condensation of soluble lignin fragments and to avoid substantial cellulose degradation. Similar reactions with other feedstock such as eucalyptus (hardwood), grasses, and a bagasse waste stream demonstrate the feasibility of the reported oxidative catalytic fractionation and the strong dependency of the product distribution on biomass variability within the different fractions.

Twenty-seven L-shaped ortho-quinone analogs were designed and synthesized using a one pot double-radical synthetic strategy followed by removing methyl at C-3 of the furan ring and introducing a diverse side chain at C-2 of the furan ring. The synthetic derivatives were investigated for their cytotoxicity activities against human leukemia cells K562, prostate cancer cells PC3, and melanoma cells WM9. Compounds TB1, TB3, TB4, TB6, TC1, TC3, TC5, TC9, TC11, TC12, TC14, TC15, TC16, and TC17 exhibited a better broad-spectrum cytotoxicity on three cancer cells. TB7 and TC7 selectively displayed potent inhibitory activities on leukemia cells K562 and prostate cancer cells PC3, respectively. Further studies indicated that TB3, TC1, TC3, TC7, and TC17 could significantly induce the apoptosis of PC3 cells. TC1 and TC17 significantly induced apoptosis of K562 cells. TC1, TC11, and TC14 induced significant apoptosis of WM9 cells. The structure-activity relationships evaluation showed that removing methyl at C-3 of the furan ring and introducing diverse side chains at C-2 of the furan ring is an effective strategy for improving the anticancer activity of L-shaped ortho-quinone analogs.

Phenolic moieties in natural organic matter (NOM) are important precursors of disinfection by-products (DBPs). In this study, the formation of chloral hydrate from chlorination of seventeen phenolic compounds, including mono-, di- and tri-hydroxybenzenes, were evaluated and the role of chlorine dioxide (ClO2) pre-oxidation on its formation pathways was explored. Chloroform, was also evaluated for comparison. Chlorination of resorcinol exhibited the highest chloral hydrate yield (2.83 +/- 0.13%) followed by chlorination of 2,4,6-trichlorophenol (0.61 +/- 0.03%). The median of chloral hydrate yields from the tested phenolic compounds was 0.22%. ClO2 pre-oxidation reduced the yields of chloroform from phenol derivatives by 37-97%, except 4-methoxyphenol, catechol and 2,3-dihydroxyphenol. On the contrary, ClO2 pre-oxidation of di- and tri-hydroxybenzenes tended to increase chloral hydrate yields in post-chlorination. Mixed results (both increases and decreases) were observed in chloral hydrate formation from chlorination of mono-hydroxybenzenes after ClO2 pre-oxidation. The changes of their formation were dependent on ClO2 pre-oxidation time and dosages. Identification of transformation products suggested that phenolic compounds were mainly converted to unsaturated carbonyl structures by ClO2. Chlorine substituted benzoquinones and cyclopent-4-ene-1,3-diones were important transformation products after a series of ring open, decarboxylation, hydrolysis and chlorine substitution reactions. The changes in the formation yields of chloral hydrate and chloroform were governed by the difference in initial phenolic precursors and the transformation products after ClO2 pre-oxidation. ClO2 pre-oxidation in water treatment can effectively reduce chloroform formation but may have a risk of increasing chloral hydrate formation. (C) 2018 Elsevier Ltd. All rights reserved.

Owing to the increasing amount of waste materials around the globe, the conversion of waste or secondary by-products to value-added products for various applications has gained significant interest. Herein, two novel agro-food waste products, Musa sp. ‘Malbhog’ peel ash (MMPA) and Musa Champa Hort. ex Hook. F. peel ash (MCPA) are used as catalysts to promote an inexpensive, efficient and eco-friendly carbon-carbon bond forming crossed aldol reaction at room temperature in solvent free conditions. Furthermore, the resulting products were subjected to reactions with these promoters in an oxygen atmosphere and led to the formation of novel flavone derivatives. Moreover, the used catalysts were properly characterized using different sophisticated analytical techniques such as Fourier-transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), Brunauer-Emmett-Teller analysis (BET), Raman spectroscopy, scanning electron microscopy energy dispersive X-ray spectroscopy (SEM-EDS), transition electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA) along with element detection using atomic absorption spectroscopy and ion chromatographic methods. These two approaches are metal free, as well as being devoid of any extra additives, co-catalysts, harsh conditions, the use of column chromatography for purification and result in a higher yield of the product within a short space of time. The catalytic abilities of the promoter were also examined to synthesize important bioactive molecules such as butein and apigenin at room temperature. With gram scale synthesis of the chalcone derivatives, the used catalysts (MMPA and MCPA) were further reused for five cycles and did not demonstrate any loss in catalytic activity.

Chiral ionic liquids (CILs) have shown a wide range of applications in variety of domains in chemistry. Because of this, synthesis and applications of CILs have always been areas of interest for research in the last 20 years. Present work describes, the synthesis of six carbohydrate based chiral ionic liquids (CCILs) by following simple procedures and their applications. Structures of the cats were confirmed through various analytical techniques like NMR spectroscopy (H-1, C-13, B-11, P-31,F-19), El-MS, and polarimetry. Designed CCILs were tested as chiral recognising agents using sodium salt of Mosher’s acid as model substrate through (FNMR)-F-19-N- spectroscopy. Further, Cats were used as organocatalyst in the enantioselective reduction of aromatic prochiral ketones to achieve corresponding chiral secondary alcohols. (C) 2019 Elsevier B.V.

I found the field of Engineering; Environmental Sciences & Ecology very interesting.

Bisphenol-A (BPA) is a constituent of polycarbonate plastics and epoxy resins, widely applied on food packaging materials. As BPA exposure results in health hazards, its efficient removal is of crucial importance. In our study five potentially probiotic microorganisms, namely Lactococcus lactis, Bacillus subtilis, Lactobacillus plantarum, Enterococcus faecalis, and Saccharomyces cerevisiae, were tested for their toxicity tolerance to BPA and their BPA removal ability. Although BPA toxicity, evident on all microorganisms, presented a correlation to both BPA addition time and its concentration, all strains exhibited BPA-removal ability with increased removal rate between 0 and 24 h of incubation. BPA degradation resulted in the formation of two dimer products in cells while the compounds Hydroquinone (HQ), 4-Hydroxyacetophenone (HAP), 4-Hydroxybenzoic acid (HBA) and 4-Isopropenylphenol (PP) were identified in the culture medium. In the proposed BPA degradation pathways BPA adducts formation appears as a common pattern, while BPA decomposition as well as the formation, and the levels of its end products present differences among microorganisms. The BPA degradation ability of the tested beneficial microorganisms demonstrates their potential application in the bioremediation of BPA contaminated foods and feeds and provides a means to suppress the adverse effects of BPA on human and animal health.

This study examines the post-ingestive fate of two host-plant derived small-molecule phenolics (the acetophenones piceol and pungenol) that have previously been shown to be toxic to the outbreaking forest pest, spruce budworm (Choristoneura fumiferana). We test first whether these compounds are transformed during passage through the midgut, and second whether the budworm upregulates activity of the detoxification enzyme glutathione-s-transferase (GST) in response to feeding on these compounds. Insects were reared on either foliage or artificial diet to the fourth instar, when they were transferred individually to one of two treatment diets, either control or phenolic-laced, for approximately 10 days, after which midguts were dissected out and used for Bradford soluble protein and GST enzyme activity analysis. Frass was collected and subjected to HPLC-DAD-MS. HPLC showed that the acetophenones do not autoxidize under midgut pH conditions, but that glucose- and glutathione-conjugates are present in the frass of insects fed the phenolic-laced diet. GST enzyme activity increases in insects fed the phenolic-laced diet, in both neutral pH and alkaline assays. These data show that the spruce budwom exhibits counter-adaptations to plant phenolics similar to those seen in angiosperm feeders, upregulating an important detoxifying enzyme (GST) and partially conjugating these acetophenones prior to elimination, but that these counter-measures are not totally effective at mitigating toxic effects of the ingested compounds in the context of our artifical-diet based laboratory experiment.
