Wu, Yubo published the artcileChiral Donor Photoinduced-Electron-Transfer (d-PET) Boronic Acid Chemosensors for the Selective Recognition of Tartaric Acids, Disaccharides, and Ginsenosides, HPLC of Formula: 165534-79-2, the publication is Chemistry – A European Journal (2011), 17(27), 7632-7644, S7632/1-S7632/67, database is CAplus and MEDLINE.

A modular approach was proposed for the preparation of chiral fluorescent mol. sensors, in which the fluorophore, scaffold, and chirogenic center can be connected by ethynyl groups, and these modules can easily be changed to other structures to optimize the mol. sensing performance of the sensors. This modular strategy to assembly chiral sensors alleviated the previous restrictions of chiral boronic acid sensors, for which the chirogenic center, fluorophore, and scaffold were integrated, thus it was difficult to optimize the mol. structures by chem. modifications. The authors demonstrated the potential of their new strategy by the preparation of a sensor with a larger scaffold. The photoinduced electron-transfer (PET) effect is efficient even with a large distance between the N atom and the fluorophore core. Furthermore, the rarely reported donor-PET (d-PET) effect, which was previously limited to carbazole, was extended to phenothiazine fluorophore. The contrast ratio, i.e., PET efficiency of the new d-PET sensor, is increased to 8.0, compared to 2.0 with the previous carbazole d-PET sensors. Furthermore, the ethynylated phenothiazine shows longer excitation wavelength (centered at 380 nm) and emission wavelength (492 nm), a large Stokes shift (142 nm), and high fluorescence quantum yield in aqueous solution (Φ=0.48 in MeOH/water, 3:1 volume/volume). Enantioselective recognition of tartaric acid was achieved with the new d-PET boronic acid sensors. The enantioselectivity is up to 10 (ratio of the binding constants toward D– and L-tartaric acid, k_D/k_L). A consecutive fluorescence enhancement/decrease was observed, thus the authors propose a transition of the binding stoichiometry from 1:1 to 1:2 as the analyte concentration increases, which is supported by mass spectra anal. The boronic acid sensors were used for selective and sensitive recognition of disaccharides and glycosylated steroids (ginsenosides).

Tahtaoui, Chouaib published the artcileOn the Use of Nonfluorescent Dye Labeled Ligands in FRET-Based Receptor Binding Studies, Synthetic Route of 606-55-3, the publication is Journal of Medicinal Chemistry (2005), 48(24), 7847-7859, database is CAplus and MEDLINE.

The efficiency of fluorescence resonance energy transfer (FRET) is dependent upon donor-acceptor proximity and spectral overlap, whether the acceptor partner is fluorescent or not. The authors report here on the design, synthesis, and characterization of two novel pirenzepine derivatives that were coupled to patent blue VF and pinacyanol dyes. These nonfluorescent compounds, when added to cells stably expressing enhanced green fluorescent protein (EGFP)-fused muscarinic M1 receptors, promote EGFP fluorescence extinction in a time-, concentration-, and atropine-dependent manner. They display nanomolar affinity for the muscarinic receptor, determined using either FRET or classical radioligand binding conditions. The authors provide evidence that these compounds behave as potent acceptors of energy from excited EGFP with quenching efficiencies comparable to those of analogous fluorescent bodipy or rhodamine red pirenzepine derivatives The advantages they offer over fluorescent ligands are illustrated and discussed in terms of reliability, sensitivity, and wider applicability of FRET-based receptor binding assays.

Fialkov, Ya. A. published the artcileComplex formation by trihydroxyglutaric acid with some metals. I. Complex formation of trihydroxyglutaric acid with trivalent iron, SDS of cas: 6443-90-9, the publication is Zhurnal Neorganicheskoi Khimii (1956), 2504-16, database is CAplus.

Optically inactive trihydroxyglutaric acid (I) reacts with aqueous Fe(NO₃)₃ to form a Fe-bearing anion. From experiments carried out at low pH values (<2) and from equilibrium studies of Fe sal⁺ (where sal is the bivalent salicylate radical) with I at pH = 3, and of Fe sal₂^– with the disodium salt of I (at pH = 6), optical d. and elec.-cond data were obtained which supported the hypothesis of a complex in which the Fe:I ratio was 1:1. At low pH values the principal species is H[FeC₅H₄O₇]. At pH = 6, the anion [FeC₅H₄O₇]^– is characteristic, whereas at pH = 10, the anion becomes [FeC₅H₃O₇]^—. The equilibrium constant for the reaction [FeC₅H₄O₇]^– + 2H⁺ â†?C₅H₆O₇^— + Fe⁺⁺⁺ is 0.12. At about pH = 6, the trihydroxyglutarate complex of Fe⁺⁺⁺ is probably more stable than is the corresponding tartrate complex.

Piccialli, Vincenzo published the artcileBromination and iodination of donor-acceptor cyclopropanes. Evidence for an ET mechanism, Formula: C5H5ClIN, the publication is Tetrahedron Letters (2002), 43(45), 8067-8070, database is CAplus.

Et 2,2-dimethoxycyclopropanecarboxylates 1a-d react easily with Br₂ and I₂ in CCl₄ or CH₂Cl₂ leading, in high yields, to 1-ethyl- or 4-methyl-2-halobutanedioates 2 and 3, resp. Bromination in the presence of pyridine, NBS, tri-Me phosphate, and iodination with ICl and ICl/pyridine was also performed. A common SET mechanism may be proposed for both halogenations; depending on the reaction conditions, bromination can also occur via acid-catalyzed or S_E2 routes. The reaction of the 2-ethoxy analogs cis-12 and trans-12 with the same halogens proceeds in a similar manner, giving 3-formyl-2-halo esters along with the corresponding diethylacetals as main products. Iodination of 12 with the catalytic system NaI/m-CPBA/18-crown-6 also was studied.

Neumann, Fernanda published the artcileDYRK1A inhibition and cognitive rescue in a Down syndrome mouse model are induced by new fluoro-DANDY derivatives, Recommanded Product: 5-Bromo-3-iodo-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine, the publication is Scientific Reports (2018), 8(1), 1-12, database is CAplus and MEDLINE.

Inhibition of DYRK1A kinase, produced by chromosome 21 and consequently overproduced in trisomy 21 subjects, has been suggested as a therapeutic approach to treating the cognitive deficiencies observed in Down syndrome (DS). We now report the synthesis and potent DYRK1A inhibitory activities of fluoro derivatives of 3,5-di(polyhydroxyaryl)-7-azaindoles (F-DANDYs). One of these compounds (3-(4-fluorophenyl)-5-(3,4-dihydroxyphenyl)-1H-pyrrolo[2,3-b]pyridine, 5a) was selected for in vivo studies of cognitive rescuing effects in a standard mouse model of DS (Ts65Dn line). Using the Morris water maze task, Ts65Dn mice treated i.p. with 20 mg/kg of 5a performed significantly better than Ts65Dn mice treated with placebo, confirming the promnesiant effect of 5a in the trisomic mice. Overall, these results demonstrate for the first time that selective and competitive inhibition of DYRK1A kinase by the F-DANDY derivative 5a may provide a viable treatment strategy for combating the memory and learning deficiencies encountered in DS.

The increasing prevalence of gout has been accompanied by a growing number of patients intolerant to or with disease refractory to the available urate-lowering therapies. This metabolic disease is a common disease with a higher prevalence in men older than 30 years and in women older than 50 years. These findings highlight the need for emerging treatments to effectively lower urate levels. In this view, we describe the xanthine oxidase (XO) inhibitory activities of the synthesized compounds I(R = Cl, Br, I, Me, tBu, OMe, CF₃, OCF₃, NO₂, NMe₂) and also their antioxidant activities. Compounds I(R = I, Me, OMe, OCF₃, NMe₂) exhibited good inhibitory activities against XO. On the other hand, compounds I(R = CF₃, OCF₃) exhibited moderate antioxidant activity.
