A naphthalimide-pyridoxal conjugate 1 has been designed and synthesized. Compound 1 forms a stable greenish yellow colored gel in DMSO:H2O (8:1 v/v). Rheological study reveals that the gel is mechanically strong (G> G) over a wide range of applied strains. The morphology of the gel as determined by FESEM shows a highly cross-linked fibrous network. The gel is anion-responsive and is selectively transformed into a sol with a color change from greenish yellow to deep blue only in the presence of F- among other anions. In CH3CN, compound 1 was also sensitive to basic anions such as F- and AcO- ions. In solution, F- was differentiated from AcO- through a color change. While the yellow colored solution of 1 in acetonitrile was changed into deep blue in the presence of F-, AcO- ions gave a faint blue coloration. A similar colorimetric differentiation of F- from AcO- has been possible in CH3CN by a reusable Schiff base-linked Merrifield resin 1a or 1b.

The interaction between pyridoxal hydrochloride (HQ) and apoCopC was investigated using Fourier transform infrared spectroscopy (FTIR), isothermal titration calorimetry (ITC), circular dichroism (CD), fluorescence spectroscopy, three-dimensional (3D) fluorescence spectroscopy, fluorescence lifetime, TNS fluorescence and docking methods. FTIR, CD, TNS fluorescence and fluorescence lifetime experiments suggested that the apoCopC conformation was altered by HQ with an increase in the random coil content and a reduction in the beta-sheet content. In addition, the data from fluorescence spectroscopy, 3D fluorescence spectroscopy and molecular docking revealed that the binding site of HQ was located in the hydrophobic area of apoCopC, and a redshift of the HQ fluorescence spectra was observed. Furthermore, ITC and fluorescence quenching data manifested that the binding ratio of HQ and apoCopC was 1:1, and the forming constant was calculated to be (7.06 +/- 0.21) x 10(5) M-1. The thermodynamic parameters Delta H and Delta S suggested that the formation of a CopC-HQcomplex depended on the hydrophobic force. Furthermore, the average binding distance between tryptophan in apoCopC and HQ was determined by means of Forster non-radioactive resonance energy transfer and molecular docking. The results agreed well with each other. As a redox switch in the modulation of copper, the interaction of apoCopC with small molecules will affect the action of the redox switch. These findings could provide useful information to illustrate the copper regulation mechanism. (C) 2018 Elsevier B.V. All rights reserved.

Sodium hydride was employed as a Michael donor under the catalysis of PdCl2 for 1,4-conjugate reductions of alpha, beta-unsaturated carbonyl compounds, which features operational simplicity, mild conditions and high atom-economy. The merits of NaH as a reductant were demonstrated by the one-pot or cascade reactions for the syntheses of complex molecules.

Background/Aims: Hydrazone and acylhydrazone derivatives, which are produced from aldehyde reacting with hydrazine or acylhydrazine, have been reported to exhibit antitumor activities. However, the angionenic effects of this kind of derivatives haven’t been elucidated. Here, we synthesized 12 pyridoxal hydrazone and acylhydrazone compounds and investigated their antiangiogenic effects and the underlying mechanisms. Method: 3-(4,5-Dimethylthiazol-2-yl)-2, 5-dipheyltetrazolium bromide assay was used to screen the inhibitory effects of the synthesized compounds on endothelial cells (ECs) proliferation. The compound with best inhibitory effect was further evaluated with wound-healing assay and tube formation assay. Calcein-Am assay was carried out to determine the content of intracellular labile iron pool (LIP). Intracellular reduced glutathione (GSH) was determined by spectrophotometry. Flow cytometry was used to determine cell cycle and apoptosis. Results: Compound 10 (3-hydroxy-5-[hydroxymethyl]-2-methyl-pyridine-4-carbaldehyde-2-naphthalen-1-acetyl hydrazone) showed the best inhibitory effect on human umbilical vascular ECs proliferation, with IC50 value of 25.4 mu mol/L. It not only inhibited wound-healing and tube formation of ECs, but also decreased the content of intracellular LIP and GSH. Furthermore, it arrested ECs cycle at S phase and induced cell apoptosis. Conclusions: Compound 10 exhibits antiangiogenic effects by reducing the content of intracellular LIP and GSH, and subsequently arresting cell cycle and inducing cell apoptosis.

A new strategy to 2-aminochromanes through catalyst-free cascade reaction of 3-trifluoroacetyl-4H-chromenes and 4H-chromene-3-carbaldehydes with cyclic secondary amines is presented. The reaction proceeds through subsequent 1,4- and 1,2-additions of amine, bimolecular elimination of trifluoroacetamide or formamide, and 6-exotrig cyclization. The latter stage is a very rare example of addition of phenols to enamines. The obtained semicyclic N,O-acetals were applied as useful precursors for the synthesis of other chromanes.

Candida albicans biofilm represents a major clinical problem due to its intrinsic tolerance to anti-fungal compounds and it has been highly related to infections in catheterized patients. Few compounds are described as able to inhibit biofilm formation or to interfere with preformed biofilm of C. albicans. Here we report the in vitro evaluation of anti-biofilm activity on C albicans ATCC 10231 of a series of new and already known amine and amide indole derivatives. Among the studied compounds, fifteen resulted active on C albicans ATCC 10231 biofilm, with BMIC50 <= 16 mu g/mL. Three of them (7, 23 and 33) showed a selectivity towards mature biofilm and the most active of them was the compound 23 (BMIC50 = 4 mu g/mL). On the other hands, two different compounds (21 and 22) were selective towards biofilm formation with BMIC50 values of 8 mu g/mL Otherwise, compounds 16 and 17 resulted active on biofilm formation, with BMIC50 of 8 mu g/mL and 2 mu g/mL respectively, and on mature biofilm with BMIC50 of 2 mu g/mL. These two last compounds also showed an interesting activity towards the planktonic cells of C albicans. A selection of the more active compounds was also evaluated on different C albicans strains (PMC1042, PMC1083 and ATCC 10261), showing a comparable or higher anti-biofilm activity, especially on mature biofilm. In vivo toxicity studies using the Galleria mellonella larvae, were finally carried out on more active indole derivatives, showing that they are poorly toxic even at the highest concentrations tested (500-1000 mu g/mL).
