Synthesis, crystal structures, and nonlinear optical (NLO) properties of new Schiff-base nickel(II) complexes. Toward a new type of molecular switch?

Jean Pierre Costes et al.

Inorganic chemistry, 44(6), 1973-1982 (2005-03-15)

An H2L Schiff-base ligand that was obtained from the monocondensation of diaminomaleonitrile and 4-(diethylamino)salicylaldehyde is reported together with four related nickel(II) complexes formulated as [Ni(L)(L')] (L' = MePhCHNH2, iPrNH2, Py, and PPh3). Crystal structures have been solved for H2L, [Ni(L)(MePhCHNH2)]

Anti-Hypochlorite, Antioxidant, and Catalytic Activity of Three Polyphenol-Rich Super-Foods Investigated with the Use of Coumarin-Based Sensors.

Karolina Starzak et al.

Biomolecules, 10(5) (2020-05-10)

The anti-hypochlorite activity of açaí (Euterpe oleracea Mart.), goji (Lyciumbarbarum L.) and schisandra (Schisandrachinensis) fruit extracts were assessed by determining the reactive chlorine species (RCS)-scavenging ability of these three "super-food" berries. In addition, the aqueous extracts obtained were employed as

Barbituric Acid Based Fluorogens: Synthesis, Aggregation-Induced Emission, and Protein Fibril Detection.

Siyang Ding et al.

Molecules (Basel, Switzerland), 25(1) (2019-12-22)

Fluorescent dyes, especially those emitting in the long wavelength region, are excellent candidates in the area of bioassay and bioimaging. In this work, we report a series of simple organic fluorescent dyes consisting of electron-donating aniline groups and electron-withdrawing barbituric

White emission magnetic nanoparticles as chemosensors for sensitive colorimetric and ratiometric detection, and degradation of ClO⁻ and SCN⁻ in aqueous solutions based on a logic gate approach.

Lihua Zhi et al.

Nanoscale, 7(27), 11712-11719 (2015-06-24)

Fluorescent chemosensors for detecting single anions have been largely synthesized. However, the simultaneous detection and degradation of multiple anions remain a major challenge. Herein we report the synthesis of a white emission nanoprobe on the basis of a Coumarin-Rhodamine CR1-Eu

NBD-based fluorescent chemosensor for the selective quantification of copper and sulfide in an aqueous solution and living cells.

Qingtao Meng et al.

Organic & biomolecular chemistry, 13(10), 2918-2926 (2015-01-09)

Chemosensors play important roles in cation and anion recognition in biological, industrial, and environmental processes. Although many efforts have been made to develop artificial fluorescent receptors for Cu(2+) and S(2-), their applications in the detection in bulk solutions are limited.

Development of multifunctional heterocyclic Schiff base as a potential metal chelator: a comprehensive spectroscopic approach towards drug discovery.

Manojkumar Jadhao et al.

Journal of biological inorganic chemistry : JBIC : a publication of the Society of Biological Inorganic Chemistry, 22(1), 47-59 (2016-11-09)

Amyloid-β peptides and their metal-associated aggregated states have been implicated in the pathogenesis of Alzheimer's disease. The present paper epitomises the design and synthesis of a small, neutral, lipophilic benzothiazole Schiff base (E)-2-((6-chlorobenzo[d]thiazol-2-ylimino)methyl)-5-diethylamino)phenol (CBMDP), and explores its multifunctionalty as a

Amino acid-based compound activates atypical PKC and leptin receptor pathways to improve glycemia and anxiety like behavior in diabetic mice.

Aejin Lee et al.

Biomaterials, 239, 119839-119839 (2020-02-18)

Differences in glucose uptake in peripheral and neural tissues account for the reduced efficacy of insulin in nervous tissues. Herein, we report the design of short peptides, referred as amino acid compounds (AAC) with and without a modified side chain

Anti-Hypochlorite and Catalytic Activity of Commercially Available Moringa oleifera Diet Supplement.

Karolina Starzak et al.

Molecules (Basel, Switzerland), 24(18) (2019-09-25)

Aiming at the assessment of the pro-health, and especially anti-hypochlorite properties of Moringa oleifera species a representative, commercially available Moringa oleifera dietary supplement was used as a substrate for the preparation of aqueous Moringa extract. The anti-hypochlorite activity of the

Poly(vinyl alcohol) boosting therapeutic potential of p-boronophenylalanine in neutron capture therapy by modulating metabolism.

Takahiro Nomoto et al.

Science advances, 6(4), eaaz1722-eaaz1722 (2020-02-06)

In the current clinical boron neutron capture therapy (BNCT), p-boronophenylalanine (BPA) has been the most powerful drug owing to its ability to accumulate selectively within cancers through cancer-related amino acid transporters including LAT1. However, the therapeutic success of BPA has

Fluorescence Quenching-Based Mechanism for Determination of Hypochlorite by Coumarin-Derived Sensors.

Karolina Starzak et al.

International journal of molecular sciences, 20(2) (2019-01-16)

A fluorescence quenching-based mechanism for the determination of hypochlorite was proposed based on spectroscopic and chromatographic studies on the hypochlorite-sensing potency of three structurally similar and highly fluorescent coumarins. The mode of action was found to rely upon a chlorination

A Novel Styryldehydropyridocolinium Homodimer: Synthesis and Fluorescence Properties Upon Interaction with DNA.

Huirong Yao et al.

Journal of fluorescence, 25(6), 1637-1643 (2015-09-19)

A novel homodimer of the styryldehydropyridocolinium dye (TPTP) has been synthesized and characterized. Free TPTP exhibited low fluorescence quantum yield and large Stokes shift (over 160 nm) in water. However, it showed a significant fluorescence turn-on effect upon intercalation into DNA

Antifungal activity of redox-active benzaldehydes that target cellular antioxidation.

Jong H Kim et al.

Annals of clinical microbiology and antimicrobials, 10, 23-23 (2011-06-02)

Disruption of cellular antioxidation systems should be an effective method for control of fungal pathogens. Such disruption can be achieved with redox-active compounds. Natural phenolic compounds can serve as potent redox cyclers that inhibit microbial growth through destabilization of cellular
