The authors report three self-assembled iron complexes that comprised an anti-parallel open form (o-L-anti), a parallel open form (o-L-syn), and a closed form (c-L) of diarylethene conformers. Under kinetic control, Fe^II₂(o-L-anti)₃ was isolated, which exhibited a dinuclear structure with diamagnetic properties. Under light-irradiation control, Fe^II₂(c-L)₃ was prepared and exhibited paramagnetism and spin-crossover behavior. Under thermodn. control and in the presence of indispensable [Fe^III(Tp^*)(CN)₃]^–, Fe^II₂(o-L-anti)₃ and Fe^II₂(c-L)₃ transformed into tetranuclear Fe^III₂Fe^II₂(o-L-syn)₂, which exhibited complete spin-crossover behavior at T_1/2 = 353 K.

Li, Ziyong published the artcileA Photoswitchable Triple Chemosensor for Cyanide Anion Based on Dicyanovinyl-Functionalized Dithienylethene, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is European Journal of Organic Chemistry (2019), 2019(22), 3614-3621, database is CAplus.

The development of new sensors for the accurate detection of cyanide anion has attracted more and more attention due to their potential applications in environmental and biol. systems. Here, two novel near-IR (NIR) photochromic compounds 1a and 1b, which were modified by the dicyanovinyl fragment with cyanide recognition function, were developed. Surprisingly, 1a presented an unprecedented triple sensing performance for cyanide anion (colorimetric-fluorescent-colorimetric), which can be used as a potential precision sensor for CN^– in environmental and biol. systems. Although 1b did not show triple detection behavior for CN^–, it could recognize CN^– and F^– synchronously and selectively by naked eyes. Also, their NIR photochromic behaviors could be modulated by the cyanide anion. Their sensing mechanism for CN^– or F^– was confirmed by absorption spectral studies, NMR titration, and DFT calculations

Boersma, Brenda J. published the artcileNeutrophil myeloperoxidase chlorinates and nitrates soy isoflavones and enhances their antioxidant properties, Product Details of C8H7ClO3, the publication is Free Radical Biology & Medicine (2003), 35(11), 1417-1430, database is CAplus and MEDLINE.

Soy isoflavones and other polyphenolics have a number of potentially important beneficial effects on the pro-oxidant aspects of chronic inflammation. The impact of inflammatory cell-specific metabolism of polyphenolics, which can include halogenation and nitration, on the properties of these compounds has not been examined Using either human neutrophils or differentiated human leukemia cells (HL-60) stimulated with phorbol ester to elicit a respiratory burst, the hypothesis that local generation of reactive oxygen and nitrogen species may metabolize and modify the biol. properties of the soy isoflavones was examined Coincubation of the stimulated cells with genistein or daidzein had no effect on the respiratory burst. Medium from stimulated cells in the presence of the isoflavones and NO₂^– increased the inhibition of copper-induced LDL oxidation Mass spectrometry anal. of this medium revealed that monochlorinated, dichlorinated, and nitrated isoflavones, formed through a myeloperoxidase-dependent mechanism, were present. The consumption of genistein in the presence of cells was both extensive and rapid with > 95% of the genistein converted to either the chlorinated or nitrated metabolites within 30 min. Chem. synthesized 3′-chlorogenistein and 3′-chlorodaidzein increased the inhibition of LDL oxidation by approx. 4-fold and 2-fold over genistein and daidzein, resp. These results lead to the hypothesis that inflammatory cell-specific metabolism of polyphenolics can modify the properties of these compounds at the local site of inflammation.

Utkin, Ilya published the artcileSpecificity of reductive dehalogenation of substituted ortho-chlorophenols by Desulfitobacterium dehalogenans JW/IU-DC1, Category: chlorides-buliding-blocks, the publication is Applied and Environmental Microbiology (1995), 61(1), 346-51, database is CAplus and MEDLINE.

Resting cells of D. dehalogenans JW/IU-DC1 grown with pyruvate and 3-chloro-4-hydroxyphenylacetate (3-Cl-4-OHPA) as the electron acceptor and inducer of dehalogenation reductively ortho-dehalogenate pentachlorophenol (PCP), tetrachlorophenols (TeCPs), the trichlorophenols 2,3,4-TCP, 2,3,6-TCP, and 2,4,6-TCP, the dichlorophenols 2,3-DCP, 2,4-DCP, and 2,6-DCP, 2,6-dichloro-4-R-phenols, where R is -H, -F, -Cl, -NO₂, -CO₂^–, or -COOCH₃, 2-chloro-4-R-phenols (2-Cl-4-RPs, where R is -H, -F, -Cl, -Br, -NO₂, -CO₂^–, -CH₂CO₂^–, or -COOCH₃), and bromophenols (2-BrP, 2,6-DBrP, and 2-Br-4ClP). Monochlorophenols, the dichlorophenols 2,5-DCP, 3,4-DCP, and 3,5-DCP, the trichlorophenols 2,3,5-TCP, 2,4,5-TCP, and 3,4,5-TCP, and the fluorinated analog of 3-Cl-4-OHPA, 3-F-4-OHPA, are not dehalogenated. A Cl substituent in position 3 (meta), 4 (para), or 6 (2nd ortho) of the phenolic moiety facilitates ortho dehalogenation in position 2. Cl in the 5 (2nd meta) position has a neg. effect on the dehalogenation rate or even prevents dechlorination in the 2 position. In general, 2,6-DCl-4-RPs are dechlorinated faster than the corresponding 2-Cl-4-RPs with the same substituent R in the 4 position. The highest dechlorination rate, however, was found for dechlorination of 2,3-DCP, with a maximum observed 1st-order rate constant of 19.4/h-g (dry weight) biomass. There is no strong linear correlation between the logarithm of pseudo-1st-order rate constants for the dehalogenation of 2,6-DCl-4-RPs and 2-Cl-4-RPs and electronic (Hammett σ_m), hydrophobic (π), and stearic (E_s) constants of the substituent R. The substrate specificity and induction pattern found for dehalogenation with the pure culture of D. dehalogenans and the original 2,4-DCP-enrichment, derived from a methanogenic sediment, were similar, suggesting that the conditions used led to only 1 type of dechlorinating organism.

Le Manach, Claire published the artcileIdentification and Profiling of a Novel Diazaspiro[3.4]octane Chemical Series Active against Multiple Stages of the Human Malaria Parasite Plasmodium falciparum and Optimization Efforts, Quality Control of 33697-81-3, the publication is Journal of Medicinal Chemistry (2021), 64(4), 2291-2309, database is CAplus and MEDLINE.

A novel diazaspiro[3.4]octane series was identified from a Plasmodium falciparum whole-cell high-throughput screening campaign. Hits displayed activity against multiple stages of the parasite lifecycle, which together with a novel sp³-rich scaffold provided an attractive starting point for a hit-to-lead medicinal chem. optimization and biol. profiling program. Structure-activity-relationship studies led to the identification of compounds that showed low nanomolar asexual blood-stage activity (<50 nM) together with strong gametocyte sterilizing properties that translated to transmission-blocking activity in the standard membrane feeding assay. Mechanistic studies through resistance selection with one of the analogs followed by whole-genome sequencing implicated the P. falciparum cyclic amine resistance locus in the mode of resistance.

cf. CA 52, 6165d. Heating 11.5 g. MeSiHCl₂ and 4.3 g. C₂H₄ in an ampul in an autoclave 3 hrs. at 320-40° gave mixed MeEtSiCl₂ and MeBuSiCl₂ in yields of 42-80% and 17-28%, resp. The use of a bare steel autoclave tended to lower the yield of MeEtSiCl₂ and raise that of BuMeSiCl₂. Similarly, Ph₃SiH and C₂H₄ in hexane 12 hrs. at 300° gave Ph₃SiEt, m. 68-70°, and Ph₃SiBu, m. 81-2°, along with some (Ph₃Si)₂O, m. 224°. Reaction of MeSiHCl₂ and propylene in the presence of a catalytic amount of H₂PtCl₆ in iso-PrOH in 1 hr. at room temperature gave MePrSiCl₂, which with MeMgBr gave known Me₃SiPr. In the telomerization of MeSiHCl₂ with C₂H₄ at 300°, the increased proportion of the olefin tended to lower steadily the yield of MeSiCl₂Et and MeSiCl₂(CH₂CH₂)₂H, while the yield of MeSiCl₂(CH₂CH₂)₃H remained substantially constant and that of MeSiCl₂(CH₂CH₂)₃H rose rapidly. Elevation of the temperature from 285° to 350° increased the yield of MeSiCl₂Et and decreased that of telomers with n over 3, while the intermediate telomer yield remained substantially constant

Heo, Seunga published the artcileBoosting photoredox catalysis using two-dimensional electride as persistent electron donor, Formula: C8H6ClF3, the publication is ACS Applied Materials & Interfaces (2021), 13(36), 42880-42888, database is CAplus and MEDLINE.

Electrides, which have excess anionic electrons, are solid-state sources of solvated electrons that can be used as powerful reducing agents for organic syntheses. However, the abrupt decomposition of electrides in organic solvents makes controlling the transfer inefficient, thereby limiting the utilization of their superior electron-donating ability. Here, we demonstrate the efficient reductive transformation strategy which combines the stable two-dimensional [Gd₂C]²⁺·2e^– electride electron donor and cyclometalated Pt(II) complex photocatalysts. Strongly localized anionic electrons at the interlayer space in the [Gd₂C]²⁺·2e^– electride are released via moderate alcoholysis in 2,2,2-trifluoroethanol, enabling persistent electron donation. The Pt(II) complexes are adsorbed onto the surface of the [Gd₂C]²⁺·2e^– electride and rapidly capture the released electrons at a rate of 10⁷ s^-1 upon photoexcitation. The one-electron-reduced Pt complex is electrochem. stable enough to deliver the electron to substrates in the bulk, which completes the photoredox cycle. The key benefit of this system is the suppression of undesirable charge recombination because back electron transfer is prohibited due to the irreversible disruption of the electride after the electron transfer. These desirable properties collectively serve as the photoredox catalysis principle for the reductive generation of the benzyl radical from benzyl halide, which is the key intermediate for dehalogenated or homocoupled products.

The rate of aminolysis of p-nitrophenyl hexanoate by benzylamine in 95.3 mol % dioxane-water was compared to the rate of this reaction when the n-pentyl group in the ester was replaced by a Me₃N⁺(CH₂)₃ group, and the benzyl group in the amine by a ^–O₃SCH₂CH₂ group. The second-order rate constant of the first reaction was 4.21 × 10^-3 L mol^-1 s^-1, the first-order rate constant for the reacting ion pair was 1.88 × 10^-2 s^-1, yielding an effective molarity of 4.47 mol L^-1 as the measure of the rate acceleration caused by this preassembly of the reactants by electrostatic attraction. Further evidence for the intermediacy of an ion pair in the reaction between the oppositely charged reactants was the observation of a special salt effect, the addition of an inert salt causing a decrease in the aminolysis rate.
