Fujiwara, Yuta published the artcilePractical C-H Functionalization of Quinones with Boronic Acids, Product Details of C9H12BClO3, the publication is Journal of the American Chemical Society (2011), 133(10), 3292-3295, database is CAplus and MEDLINE.

A direct functionalization of a variety of quinones with several boronic acids has been developed. This scalable reaction proceeds readily at room temperature in an open flask using catalytic silver(I) nitrate in the presence of a persulfate co-oxidant. The scope with respect to quinones is broad, with a variety of alkyl- and arylboronic acids undergoing efficient cross-coupling. The mechanism is presumed to proceed through a nucleophilic radical addition to the quinone with in situ reoxidation of the resulting dihydroquinone. This method has been applied to complex substrates, including a steroid derivative and a farnesyl natural product.

Wang, Ling published the artcileLuminescence-Driven Reversible Handedness Inversion of Self-Organized Helical Superstructures Enabled by a Novel Near-Infrared Light Nanotransducer, Product Details of C15H14Cl2S2, the publication is Advanced Materials (Weinheim, Germany) (2015), 27(12), 2065-2069, database is CAplus and MEDLINE.

Stimuli-directing self-organized supramol. architectures with desired properties provide the necessary thrust in the nanofabrication of intelligent mol. materials and devices. There have been only a few reports on using chiral photoresponsive mols. such as chiral azobenzenes,overcrowded alkenes,and chiral diarylethen as dopants for light-induced handedness inversion upon UV or visible-light irradiation After investigating the NIR-light-directed photoisomerization process of chiral switch (S, S)-8 and core-multishell nanotransducers in organic solvent, we examined the performance of the self-organized helical superstructures incorporated with the mol. switch and nanotransducers. Novel core-multishell UCNPs with dual wavelength NIR light transduction properties were rationally designed and synthesized by judiciously distributing the Tmn and Er3+ emissive ions in appropriate layers to furnish UV and visible luminescence on demand upon NIR irradiation at different wavelengths.

Synthesis and ¹H NMR spectra in D₂O of 4 betaines and 19 betaine complexes with mineral acids containing 2 or 3 CH₂ groups in the tether, N⁺-(CH₂)_n-COO^–, n=2,3, and diverse volume of the pos. charged groups are reported. In compounds containing three CH₂ groups in the tether and three substituents at the nitrogen atom or α, α’-disubstituted pyridine ring, a characteristic multiplet for an AA’MM’X₂ spin system is observed This is consistent with preference for trans conformation (68-85%). In the spectra of compounds with two CH₂ groups in the tether or three CH₂ groups and unsubstituted pyridine ring, the multiplet changes to a triplet and gives apparent A₂X₂ and A₂M₂X₂ spectra, resp., consistent with no significant conformational preference. Both the number of CH₂ groups in tether and the bulkiness of the charged groups are responsible for the observed differences of N⁺CH₂ multiplicity and reflect changes in conformational preferences. According to the PM3 calculations, in the gas phase a gauche-like conformer is more stable than the trans, but in aqueous solution it is reverse.

The quinoline-5,8 dicarboxylic acid scaffold has been identified by a fragment-based approach as new potential lead compound for the development of JMJD3 inhibitors. Among them, 3-(2,4-dimethoxypyrimidin-5-yl)quinoline-5,8-dicarboxylic acid (compound 3) shows low micromolar inhibitory activity against Jumonji domain-containing protein 3 (JMJD3). The exptl. evaluation of inhibitory activity against seven related isoforms of JMJD3 highlighted an unprecedented selectivity toward the biol. target of interest.

Parry, Geraint published the artcileNovel auxin transport inhibitors phenocopy the auxin influx carrier mutation aux1, Quality Control of 33697-81-3, the publication is Plant Journal (2001), 25(4), 399-406, database is CAplus and MEDLINE.

The hormone auxin is transported in plants through the combined actions of diffusion and specific auxin influx and efflux carriers. In contrast to auxin efflux, for which there are well documented inhibitors, understanding the developmental roles of carrier-mediated auxin influx has been hampered by the absence of specific competitive inhibitors. However, several mols. that inhibit auxin influx in cultured cells have been described recently. The physiol. effects of two of these novel influx carrier inhibitors, 1-naphthoxyacetic acid (1-NOA) and 3-chloro-4-hydroxyphenylacetic acid (CHPAA), have been investigated in intact seedlings and tissue segments using classical and new auxin transport bioassays. Both mols. do disrupt root gravitropism, which is a developmental process requiring rapid auxin redistribution. Furthermore, the auxin-insensitive and agravitropic root-growth characteristics of aux1 plants were phenocopied by 1-NOA and CHPAA. Similarly, the agravitropic phenotype of inhibitor-treated seedlings was rescued by the auxin 1-naphthaleneacetic acid, but not by 2,4-dichlorophenoxyacetic acid, again resembling the relative abilities of these two auxins to rescue the phenotype of aux1. Further investigations have shown that none of these compounds block polar auxin transport, and that CHPAA exhibits some auxin-like activity at high concentrations While results indicate that 1-NOA and CHPAA represent useful tools for physiol. studies addressing the role of auxin influx in planta, 1-NOA is likely to prove the more useful of the two compounds

Kinetics of controlled simultaneous copolymerization of hexamethylcyclotrisiloxane (D₃) with functional cyclotrisiloxanes was studied using n-BuLi in THF as initiator. Trifunctional (MeXSiO)₃ (X₃), where X = vinyl, trifluoropropyl or chloropropyl group, and monofunctional monomers [(Me₂SiO)₂MeXSiO] (D₂X), where X = cyanopropyl or n-octyl group, were used as monomers. Reactivity ratios for each pair of comonomers were determined and the possibility of synthesis of gradient copolymers by this method is discussed.

Cossement, D. published the artcileSelf-assembled monolayers of branched alkylsilanes on polycrystalline titanium surfaces, Name: Dichloro(methyl)(octyl)silane, the publication is Surface and Interface Analysis (2000), 30(1), 56-60, database is CAplus.

The silanization reaction on polycrystalline Ti surfaces was studied from the point of view of engineering a densely packed chemisorbed layer at the interface. For this purpose methyl-n-octyldichlorosilane (MODCS) and 2-methyl-1-trichlorosilylundecane (2MTCSU) were used and compared with n-octyltrichlorosilane (OTCS). XPS and contact angle measurements reveal that 2MTCSU forms well covering but not so densely packed monolayers as does OTCS. In contrast to 2MTCSU, MODCS does not provide a proper modification of the surface because of the small amount of mols. chemisorbed on the surface.
