Timperley, Christopher M. published the artcileFluorinated phosphorus compounds Part 6. The synthesis of bis(fluoroalkyl) phosphites and bis(fluoroalkyl) phosphorohalidates, HPLC of Formula: 2240-88-2, the publication is Journal of Fluorine Chemistry (2002), 113(1), 65-78, database is CAplus.

Reaction of P trichloride with tert-BuOH and fluoro alcs. gave bis(fluoroalkyl) phosphites (R_FO)₂P(O)H in 42-89% yield, where R_F = HCF₂CH₂, H(CF₂)₂CH₂, H(CF₂)₄CH₂, CF₃CH₂, C₂F₅CH₂, C₃F₇CH₂, (CF₃)₂CH, (FCH₂)₂CH, CF₃Me₂C, (CF₃)₂CH₃C, CF₃CH₂CH₂, C₄F₉CH₂CH₂ and C₆F₁₃CH₂CH₂. Treatment of these with Cl₂ in CH₂Cl₂ gave the bis(fluoroalkyl) phosphorochloridates (R_FO)₂P(O)Cl in 49-96% yield. The chloridate (CF₃CH₂O)₂P(O)Cl was isolated in much lower yield from the interaction of thionyl chloride with bis(trifluoroethyl) phosphite. Heating the latter in CH₂Cl₂ with KF and a catalytic amount of HO₂CCF₃ gave the corresponding fluoridate (CF₃CH₂O)₂P(O)F in 84% yield. Treatment of bis(trifluoroethyl) phosphite with Br₂ or I₂ gave the bromidate (CF₃CH₂O)₂P(O)Br and iodidate (CF₃CH₂O)₂P(O)I in 51 and 46% yield, resp. The iodidate is the 1st dialkyl phosphoroiodidate to have been isolated and characterized properly-its discovery lags behind the 1st isolation of a dialkyl phosphorochloridate by over 130 yr. The fluoroalkyl phosphoryl compounds are generally more stable than known unfluorinated counterparts.

Fausto, Catia published the artcileDifferential olive grove management regulates the levels of primary metabolites in xylem sap, Recommanded Product: 3-Hydroxyphenylacetic acid, the publication is Plant and Soil (2021), 460(1-2), 281-296, database is CAplus.

Aims: The conventional management adopted in many Mediterranean olive orchards makes them more vulnerable to climate change and attacks by pathogens, due to the decreased chem. plant defenses. In this scenario, a metabolomic anal. was carried out on the xylem sap (Xsap) of olive plants (Olea europaea L.) grown in the Salento peninsula (Italy). Trials were carried out in two olive groves, one organically and one conventionally managed (controls), successively both converted to sustainable management (i.e. frequent light pruning, soil and foliar fertilization, cover crops). The Xsap was extracted from the shoots of olive plants using a Scholander pressure chamber pressurized with N2 and gas chromatog.-mass spectrometry metabolite profiling was performed in the Xsap. An untargeted gas chromatog. mass spectrometry (GC-MS) based metabolomic anal. of primary metabolites (including underivatized volatiles) of the Xsap revealed relative abundances of 153 identified metabolites and 336 unknown features across the 12 samples from four groups of samples. Among them, more than half were involved in the primary metabolism Many of the compounds with increased levels under sustainable management (such as amino acids, soluble sugars, sugar alcs.) have a well-known role as osmoprotectants or are involved in plant defense, growth and development during stress or recovery stages. Sustainable management in olive groves can increase the ability of plants to overcome environmental stressors and enhance ecosystem balance.

Di Francesco, A. published the artcileApple pathogens: Organic essential oils as an alternative solution, Quality Control of 106-25-2, the publication is Scientia Horticulturae (Amsterdam, Netherlands) (2022), 111075, database is CAplus.

Fusarium avenaceum, Botrytis cinerea, Penicillium expansum, and Neofabraea vagabunda, represent postharvest diseases which cause significant apple losses. The aim of this study was therefore to evaluate the effects of organic essential oils (EOs) (Thymus vulgaris, Lavandula angustifolia, Rosmarinus officinalis) against apple pathogens both in vitro and in vivo, as an integrated management tool. By GC-MS anal. a total of 101 compounds principally belonging to the groups of terpenes and terpenoids were detected in the extracted EOs. In vitro results showed T. vulgaris as the most active EO, both as agar infusion or biofumigant. Through agar infusion, starting from the lowest concentration (0.2 mL L-1), T. vulgaris reduced by 74.9%, 86.1%, 66.9%, and 45.7% F. avenaceum, B. cinerea, P. expansum, and N. vagabunda mycelial growth, resp.; as biofumigant, it completely inhibited the growth of all the tested mycelial pathogens. Application of EOs on apples through dipping treatment displayed some potential to inhibit the above-mentioned pathogens, especially by T. vulgaris and L. angustifolia. The efficacy of these organic EOs is probably strictly correlated to the chem. composition

Saleemi, Sidra published the artcileBio-Inspired Hierarchical Carbon Nanotube Yarn with Ester Bond Cross-Linkages towards High Conductivity for Multifunctional Applications, Computed Properties of 111-29-5, the publication is Nanomaterials (2022), 12(2), 208, database is CAplus and MEDLINE.

The cross-linked hierarchical structure in biol. systems provides insight into the development of innovative material structures. Specifically, the sarcoplasmic reticulum muscle is able to transmit elec. impulses in skeletal muscle due to its cross-linked hierarchical tubular cell structure. Inspired by the cross-linked tubular cell structure, we designed and built chem. cross-links between the carbon nanotubes within the carbon nanotube yarn (CNT yarn) structure by an esterification reaction. Consequently, compared with the pristine CNT yarn, its elec. conductivity dramatically enhanced 348%, from 557 S/cm to 1950 S/cm. Furthermore, when applied with three voltages, the electro-thermal temperature of esterified CNT yarn reached 261°C, much higher than that of pristine CNT yarn (175°C). In addition, the esterified CNT yarn exhibits a linear and stable piezo-resistive response, with a 158% enhanced gauge factor (the ratio of elec. resistance changing to strain change ∼1.9). The superconductivity, flexibility, and stable sensitivity of the esterified flexible CNT yarn demonstrate its great potential in the applications of intelligent devices, smart clothing, or other advanced composites.

Hibi, Takao published the artcilePurification of the functional plant membrane channel KAT1, Product Details of C14H28O5S, the publication is Biochemical and Biophysical Research Communications (2008), 374(3), 465-469, database is CAplus and MEDLINE.

The inward-rectifying K⁺ channel KAT1 is expressed mainly in Arabidopsis thaliana guard cells. The purification of functional KAT1 has never been reported. The authors investigated the extraction of the plant K⁺ channel KAT1 with different detergents, as an example for how to select detergents for purifying a eukaryotic membrane protein. A KAT1-GFP fusion protein was used to screen a library of 46 detergents for the effective solubilization of intact KAT1. Then, a “test set” of three detergents was picked for further anal., based on their biochem. characteristics and availability. The combination use of the selected detergents enabled the effective purification of functional KAT1 with affinity and gel-filtration chromatog.

Devi, Apramita published the artcileTiming of inoculation of Oenococcus oeni and Lactobacillus plantarum in mixed malo-lactic culture along with compatible native yeast influences the polyphenolic, volatile and sensory profile of the Shiraz wines, Application of cis-3,7-Dimethyl-2,6-Octadien-1-Ol, the publication is LWT–Food Science and Technology (2022), 113130, database is CAplus.

Malolactic fermentation (MLF) is a secondary wine fermentation resulting from lactic acid bacteria (Oenococcus oeni or Lactobacillus plantarum), especially in cool climates. MLF reduces acidity, improves body, mouthfeel, aroma complexity, and stabilizes the wine. Nevertheless, the traditional MLF using single culture is often associated with stuck fermentation, increased volatile acidity and color loss in wine. Thus, studies on mixed blend of L. plantarum and O. oeni to improve chem. and sensory profiles are gaining importance. The first study on different timing of inoculation of dual malo-lactic culture for the vinification of Shiraz wine aims to understand interactions between the wine cultures (Saccharomyces cerevisiae AAV2, L. plantarum Lp 1 and O. oeni Oo 1). The wines were compared based on chem. properties, phenolic and volatile profiles, and sensory anal. The study highlighted that early or mid-inoculated MLF wines have higher anthocyanins, flavonoids, syringol, esters, vanillate derivatives, benzaldehyde, and free terpenes compared to traditional MLF wines. The wines were rated high for purple red color, tannin, body, and overall acceptability. Hence, it was concluded that the inoculation of Lp 1 and Oo 1, either after 7 or 14 days of alc. fermentation by yeast AAV2, yield the desired quality Shiraz wine.

Kondratenko, Yulia A. published the artcileSynthesis, crystal structure and properties of tris(2-hydroxypropyl)ammonium based protic ionic liquids and protic molten salts, Quality Control of 122-20-3, the publication is Journal of Molecular Liquids (2021), 114717, database is CAplus.

Fifteen tris(2-hydroxypropyl)ammonium salts (TPA salts) were first synthesized by a direct reaction of proton transfer from carboxylic acids to tris(2-hydroxypropyl)amine. The composition and structure of synthesized TPA salts were confirmed by NMR (¹H, ¹³C), FT-IR spectroscopy and elemental anal. The crystal structure and conformation of the tris(2-hydroxypropyl)ammonium cation in salts of salicylic, nicotinic and malonic acids were studied by single-crystal X-ray diffraction. Thermal stability studies had shown that TPA salts were protic ionic liquids with melting temperatures below 100°C or room-temperature ionic liquids or molten salts. Selected TPA salts were investigated for their antimicrobial activity against bacterial and fungus strains. In addition, it was shown for the first time that synthesized TPA salts could be used as potential buffer agents for ⁶⁸Ga-radiolabeling of bifunctional chelating agents (BCA) and clin. relevant peptides (PSMA-11, PSMA-617, DOTA-NOC, DOTA-TATE).
