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.

Gas Permeation and Hemocompatibility of Novel Perfluorinated Polymers for Blood Oxygenation

Gas permeation properties of three highly permeable perfluorinated polymers (polyhexafluoropropylene (PHFP), amorphous Teflon AF2400, and polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) (PPFMED)), which are promising materials for the dense thin layer of hollow fiber membranes for extracorporeal membrane oxygenation have been studied using nitrogen, oxygen, and carbon dioxide. Hemocompatibility of the polymeric films has also been investigated on whole blood from healthy donors. Gas permeation of the polymers increases in the order PHFP < PPFMEDD < AF2400, with PHFP alone having the permeability coefficients of the gases do not below those of polydimethylsiloxane applied as the selective layer of blood oxygenation membranes. Hemocompatibility of the polymers declines in the order PHFP > PPFMED > AF2400, with the most permeable polymer AF2400 exhibiting the worst hemocompatibility among the other polymers studied. Polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) is shown to be the most appropriate polymer to fabricate hollow fiber membranes for blood oxygenation.

Ultraclean Graphene Transfer Using a Sacrificial Fluoropolymer Nanolayer: Implications for Sensor and Electronic Applications

The transfer of chemical vapor deposited (CVD) monolayer graphene by using poly[4,5-difluoro-2,2-bis-(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene] (Teflon AF1600) fluoropolymer (FP) as a sacrificial nanolayer is demonstrated. Owing to the chemical inertness of FPs, the AF1600-assisted transfer produces an ultraclean surface with excellent transfer integrity. Compared with the widely used poly(methyl methacrylate)-assisted transfer, AF1600-assisted transfer produces better overall transfer quality as measured by root-mean-square (RMS) roughness. Adding a noncovalent surface monolayer between the graphene and the FP facilitates the FP removal after graphene transfer, resulting in a surface with RMS roughness of 0.4-0.5 nm due to a better reduction of the surface residue after transfer. The remaining residue is found to be primarily associated with thermal-expansion ripples in the graphene that act as trapping sites for the low-molecular-weight FP particles. This work provides a scalable solution to clean CVD graphene transfer for many applications, particularly in sensors where surface cleanliness is paramount. The use of prefunctionalized graphene via self-assembled monolayers as molecular scale passivation layer could further enhance its utility as an integration scheme for graphene sensors.

Analytic calculation of ground state splitting in symmetric double well potential

The exact solution of the one-dimensional Schrodinger equation with symmetric trigonometric double-well potential (DWP) is obtained via angular oblate spheroidal function. The results of stringent analytic calculation for the ground state splitting of ring-puckering vibration in the 1,3-dioxole (as an example of the case when the ground state tunneling doublet is well below the potential barrier top) and 2,3-dihydrofuran (as an example of the case when the ground state tunneling doublet is close to the potential barrier top) are compared with several variants of approximate semiclassical (WKB) ones. This enables us to verify the accuracy of various WKB formulas suggested in the literature: 1. ordinary WKB, i.e., the formula from the Landau and Lifshitz textbook; 2. Garg’s formula; 3. instanton approach. We show that for the former case all three variants of WKB provide good accuracy while for the latter one they are very inaccurate. The results obtained provide a new theoretical tool for describing relevant experimental data on IR spectroscopy of ring-puckering vibrations.

Pruinosanones A-C, anti-inflammatory isoflavone derivatives from Caragana pruinosa

Pruinosanone A (1), a novel spirochromone, was isolated from the roots of Caragana pruinosa. Two biogenetically related isoflavone intermediates, pruinosanones B and C (2 and 3), were also isolated, together with five known analogs identified as 3-hydroxy-9-methoxypterocarpan (4), 7,2′-dihydroxy-4′-methoxyisoflavanol (5), retusin-8-methylether (6), 7,2′-dihydroxy-8,4′-dimethoxy isoflavone (7) and 7,3′-dihydroxy-8,4′-dimethoxy isoflavone (8). The structures of 1-3 were elucidated based on extensive spectroscopic methods. Notably, 1 is the first example of a spirochromone possessing an unprecedented pentacyclic skeleton containing a spiro[benzo[d][1,3] dioxole-2,3′-chroman]-4′-one motif, which was confirmed by X-ray diffraction analysis. A plausible biosynthetic pathway for 1 was also proposed. Compounds 1-8 were tested for their ability to inhibit nitric oxide (NO) production in LPS-induced RAW 264.7 macrophages, and compounds 1-3 were the most potent inhibitors of NO production, with IC50 values of 1.96, 1.93 and 1.58 mu M, respectively. A structure-activity relationship analysis revealed that the fused 2-isopropenyl-2,3-dihydrofuran moiety plays a vital role in the potency of these compounds. Moreover, 1 was found to significantly inhibit inducible nitric oxide synthase (iNOS) protein expression, which accounts for the potent inhibition of NO production by this spirochromone.

LOW-TEMPERATURE DIELECTRIC BEHAVIOR OF POLYMERS AND COPOLYMERS OF TETRAFLUOROETHYLENE

Dielectric measurements were made on a series of polymers containing tetrafluoroethylene at temperatures from 10 to 300 K and frequencies from 10 to 10(5) Hz. In all cases, the local-mode gamma-relaxation was observed. In FEP and PFA, which contain CF3 and n-C3F7O branches, respectively, there is also a lower temperature relaxation for which the activation entropy is close to zero. In Teflon AF, an amorphous copolymer containing a large number of dioxole rings, four relaxations were observed including the glass transition near 200-degrees-C.
