Piperine-like alkamides from Piper nigrum induce BDNF promoter and promote neurite outgrowth in Neuro-2a cells

Black pepper (Piper nigrum) contains a variety of alkamides. Among them, piperine has been reported to have antidepressant-like effects in chronically stressed mice, but little is known about the biological activity of other alkamides. In this study, we investigated the effects of alkamides from white pepper (P. nigrum) on neuronal cells. Twelve alkamides were isolated from white pepper MeOH extracts, and their chemical structures were identified by NMR and MS analyses. The compounds were subjected to assays using the luciferase-reporter gene under the control of the BDNF promoter or cAMP response element in mouse neuroblastoma Neuro-2a cells. In both assays, marked reporter-inducing activity was observed for piperine (1), piperettine (2) and piperylin (7), all of which have in common an (E)-5-(buta-1,3-dien-1-yl)benzo[d] [1, 3] dioxole moiety. Piperettine (2) and piperylin (7) tended to increase endogenous BDNF protein levels. Furthermore, piperylin (7) promoted retinoic acid-induced neurite outgrowth. These results suggest that piperylin (7), or analogues thereof, may have a beneficial effect on disorders associated with dysregulation of BDNF expression, such as depression.

A unique rhodamine-based ‘off-on’ molecular spy for selective detection of trivalent aluminum and chromium ions: Synthesis, crystal structure and spectroscopic properties along with living cell imaging

The well known rhodamine framework offers an ideal model for the development of fluorescence enhanced chemosensors. Herein, a novel and simple molecule chemosensor, (E)-2-((benzo[d][1,3] dioxol-4-ylmethylene)amino)-3′,6′-bis(diethylamino)spiro[isoindoline-1,9′-xanthen]-3-one (L), has been designed by combining a rhodamine B hydrazide and a benzo[d][1,3]dioxole-4-carbaldehyde in a single molecule to prove the selectivity and sensitivity for Al3+ and Cr3+ in a dual-channel mode (fluorescence emission and UV-Vis). The signal transduction occurred by the increase of conjugation in the ring-open form than in the ring-closed form. Furthermore, the chemosensor L could also be used as an imaging probe without cytotoxicity for uptake and detection of Al3+ ion in HeLa cells. (C) 2014 Elsevier B.V. All rights reserved.

Electrical conductivity of thin-film composites containing silver nanoparticles embedded in a dielectric fluoropolymer matrix

Thin-film nanocomposites, consisting of silver nanoparticles embedded in a dielectric fluoropolymer matrix (poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene]), were synthesized using vapor-phase co-deposition. The electrical conductivity of these composites was measured in-situ as a function of film thickness at various metal concentrations. At low metal concentrations (< 30%), dielectric behavior and very little change with film thickness were observed. At moderate to high silver loadings (30-80%) a large increase in electrical conductivity was observed as the films grew thicket. As the thickness increased further, the conductivity flattened out. At very high silver content (> 90%), fragmented fractal nanoclusters were able to further interconnect to achieve the percolation process and eventually evolve into a metallic continuum with dielectric polymer inclusions.

Intermolecular interactions in target organophilic pervaporation through the films of amorphous Teflon AF2400

Organic-organic pervaporation was studied for high free volume material-amorphous Teflon AF2400 (copolymer of 2,2-bis-trifluoromethyle-4,5-difluoro dioxole and tetrafluoroethylene). Individual organic components-acetone (A), chloroform (Ch) and methanol (M) that are capable of forming azeotrope mixtures as well as binary mixtures A-Ch and M-Ch were tested as penetrants. The process was studied at different temperatures (10-50 degrees C) over a wide range of composition of mixtures (10-90%). Evidence of formation of associates between the components in the mixtures in the liquid phase and during mass transfer through the films were obtained. IR spectra and quantum-chemical calculations supported these conclusions. (c) 2005 Elsevier B.V. All rights reserved.

A Novel Small Molecule, (E)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5 ‘-methyl-7,7 ‘-dimethoxy-4,4 ‘-bibenzo[d][1,3]dioxole-5,5 ‘-dicarboxylate (7k), Alleviates the Development of D-Galactosamine/Lipopolysaccharide-Induced Acute Liver Failure by Inhibiting Macrophage Infiltration and Regulating Cytokine Expression

Acute liver failure (ALF) is a relatively rare liver disorder that leads to the massive death of hepatocytes. Our previous study reported that a novel small-molecule agent, (E)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5-methyl-7,7′-dimethoxy-4,4′-bibenzo[d][1,3]dioxole-5,5’-dicarboxylate (7k), possessed potent anti-inflammatory activity. In the present study, we further evaluated the therapeutic effects of 7k on lipopolysaccharide (LPS)-induced ALF and investigated the mechanisms of action. Our results demonstrated that 7k inhibited the migration of RAW264.7 macrophages, blocked the activity of nuclear factor-kappa B protein, and dose-dependently down-regulated the production of interleukin (IL)-1 beta, tumor necrosis factor-alpha, and IL-6 as well as their corresponding mRNAs in RAW264.7 cells. Oral administration of 7k at a dose of 50 mg/kg significantly suppressed the serum level of enzyme activity and prevented the damage of liver tissue in D-galactosamine/LPS-induced ALF. Treatment with 7k also remarkably blocked the increase in the number of CD11b(+)- and CD68(+)-positive cells in the liver, and in vivo nuclear factor-kappa B activity, known to regulate inflammatory responses in many cell types, was effectively inhibited. The serum concentrations and hepatic mRNA expression of proinflammatory cytokines tumor necrosis factor-alpha, IL-1 beta, and IL-6 were markedly downregulated in mice by the treatment of 7k. In summary, 7k alleviated the development and progression of D-galactosamine/LPS-induced ALF by inhibiting macrophage infiltration and regulating the expression of cytokines.

Inhalation toxicity of Dioxole and Dioxolane compounds in the rat

Four chemicals (Dioxole 418, Dioxolane 418, Dioxolane 416 and Dioxolane 456) which are used as stabilizers in highresolution image were tested or both their acute and repeated inhalation toxicity in the rat using nose-only exposures. Acute studies determined the lethal concentrations following a single 4-hour exposure, repeated exposure inhalation studies determined the potency and target tissue(s) following 6-hour/day exposures, 5 days/week for 2 weeks. Each of the chemicals was at least mildly toxic acutely with approximate lethal concentrations of > 1,500 ppm for Dioxole 418, 1,300 ppm for Dioxolane 418, 1,700 ppm for Dioxolane 416, and 4,300 ppm for Dioxolane 456. No specific unusual clinical signs of response were seen in the rats exposed acutely. Repeated exposures with Dioxole 418 and Dioxolane 418 resulted in no evidence of toxicity with NOAEL’s being 440 and 500 ppm respectively (the highest concentrations tested). Repeated exposures to 250 ppm Dioxolane 456 were not tolerated with mortalities observed after exposure. Severe bone marrow hypoplasia along with reductions in platelet and neutrophil counts were observed at this concentration with less severe hemopoietic changes seen also at 10 and 51 ppm. The no-effect level for Dioxolane 456 was determined to be 10 ppm in female rats and I ppm in males. The same hemopoietic effects were seen with Dioxolane 416 at exposures of 53 ppm or greater in males but not in females exposed to 53 ppm Dioxolane 416. Hepatocellular hypertrophy and depression of serum alkaline phosphatase activity were seen in male rats exposed to 500 but not 53 ppm Dioxolane 416. Testicular degeneration was also seen in rats exposed to 500 ppm Dioxolane 416. The NOAEL was 5 ppm for the chemical.

Electrochemical Behavior and Antioxidant Activity of Hibalactone

Hydrocotyle umbellata L. is a groundcover plant that has been used in the folk medicine of Argentina, Brazil, Cuba e India, mainly to reduce inflammatory processes. The lignan, hibalactone, can be isolated from the roots of the plant. In the anti-inflammatory and antioxidant activity of such natural products, it is believed that the mechanism of action involves the butyrolactone ring, which would act as free pharmacophore. In this study, electrochemical, spectrometric and computational chemistry approaches were used to evaluate the lignan antioxidant activity and electro-oxidation pathway. Electrochemical measurements were performed in a 3 mL cell, operated in a three electrode system, consisting in an Ag/AgCl reference electrode, platinum as counter electrode and glassy carbon electrode was used as working electrode. Radical scavenging assays were performed with DPPH and ABTS. In the computational chemistry approach geometry, optimization was performed with semi empirical calculations (PM3) and the orbitals/charges calculations were performed by the extended Huckel method. The voltammetry showed a very slight variation with pH alteration, which can be justified by lactone hydrolysis that occurs in acidic and basic pH. In the HOMO and total charge density distribution it was possible to observe that the higher prevalence was in the benzo[1,3]dioxole rings and in the alkenes/alkanes in proximity with the lactone ring. The hibalactone displayed a single quasi-reversible electro-oxidation. Given the HOMO and charge density distribution in the lignan, more so the single oxidation in the evaluated potential, it is reasonable to infer that the alkene bonded with the lactone ring was a probable site of oxidation.

Intramolecular Diels-Alder cycloadditions of cis-cyclohexadienediols derived enzymatically from (2-azidoethyl)benzene. Construction of highly functionalized bridged isoquinoline synthons

(3aR,7aS)-4-(2-Azidoethyl)-2,2-dimethyl-3a,7a-dihydrobenzo[1,3]dioxole (22) was converted in two steps to trienes 23 and 24, which upon heating underwent intramolecular Diels-Alder reactions to give mixtures of isomeric 11,11-dimethyl-5-oxo-10,12-dioxa-4-azatetracyclo[6.5.2.0(1.6).0(9,13)]pentadec-14-ene-7-carboxylates 25, 26 and 27, 28, respectively. These products were separated and identified. For comparison, intermolecular Diels-Alder cycloaddition of diene 22 with maleic anhydride was carried out. Products of this reaction, 1-(2-azidoethyl)-4,4-dimethyl-3,5,10-trioxatetracyclo[5.5.2.0(2,6).0(8,12)]tetradec-13-ene-9,11-diones (29 and 30) were converted to methyl ester analogues of 31 and 32 in a two-step sequence. The stereochemical outcome of these cycloadditions is discussed as well as their possible utilization in organic synthesis, especially in total synthesis of some alkaloids.
