Abstract
A summary of the resource.
Development of new antimicrobial agents, capable of combating resistant and multidrug-resistant fungal and bacterial clinical strains, is necessary. This study presents the synthesis and antimicrobial screening of 42 2-substituted-1,4-benzenediols, being 10 novel compounds. In total, 23 compounds showed activity against fungi and/or bacteria. Benzenediol compounds 2, 5, 6, 8, 11, and 12 demonstrated broad spectrum antimicrobial actions, including resistant and multidrug-resistant species of dermatophytes (Trichophyton mentagrophytes), Candida spp. and the ESKAPE panel of bacteria. Minimum inhibitory concentrations of these compounds for fungi and bacterial strains ranged from 25 to 50 µg/ml and 8–128 µg/ml, respectively. The antifungal mechanism of action is related to the fungal cell wall of dermatophytes and membrane disruption to dermatophytes and yeasts, in the presence of compound 8. Specific structural changes, such as widespread thinning along the hyphae and yeast lysis, were observed by scanning electron microscopy. The effects of compound 8 on cell viability are dose-dependent; however they did not cause genotoxicity and mutagenicity in human leukocyte cells nor haemolysis. Moreover, the compounds were identified as nonirritant by the ex-vivo Hen’s egg test-chorioallantoic membrane (HET-CAM). The furan-1,4-benzenediol compound 5 showed in vivo efficacy to combat S. aureus infection using embryonated chicken eggs. Therefore, the compounds 8, and 5 are promising as hits for the development of new antimicrobial drugs with reduced toxicity.

Abstract
A summary of the resource.
The crystal structure of the title compound, [Ni3(C8H4O4)3(C3H7NO)4], is a two-dimensional coordination network formed by trinuclear linear Ni3(tp)3(DMF)4 units (tp = terephthalate = benzene-1,4-di­carboxyl­ate and DMF = di­methyl­formamide) displaying a characteristic coordination mode of acetate groups in polynuclear metal–organic compounds. Individual trinuclear units are connected through tp anions in a triangular network that forms layers. One of the DMF ligands points outwards and provides inter­actions with equivalent planes above and below, leaving the second ligand in a structural void much larger than the DMF mol­ecule, which shows positional disorder. Parallel planes are connected mainly through weak C—H⋯O, H⋯H and H⋯C inter­actions between DMF mol­ecules, as shown by Hirshfeld surface analysis.

The title complex, {[Ni(hab)]K[(hab)Ni]}·SCN (H 2 hab is bis(2-hydroxy-3-methoxybenzylidene)-1,2-diaminobenzene) crystallizes in the Monoclinic space group P2 1 /c with unit cell dimensions a = 11.5891 (13) Å, b = 17.307 (2) Å, c = 19.781 (2) Å,β = 92.368 (10)°, V = 3964.2 (8) Å 3 , Z = 4, R 1 = 0.106 and wR 2 = 0.305. The Ni II cation is in a N 2 O 2 inner and has a distorted square-planar coordination environment. The Ni II cation is linked by two imino nitrogen atoms and two bridged phenolate oxygen atoms. The potassium cation is octacoordinated in O 8 donor site and linked by four bridged phenolate oxygen atoms and four methoxy oxygen atoms. In the crystal, the {[Ni(hab)]K[(hab)Ni]} + cations form layers parallel to the ab plane. The SCN-anions are located in the interlayer space and connect the layers via C-H…N and C-H…S hydrogen bonds, forming three dimensional network.

Abstract
A summary of the resource.
The design of white-light emitting materials for solid-state lighting technology is governed by the combination of independent red, green and blue emitting centers. Many mixed-lanthanide single phase white-light source materials have been produced so far by a careful trial and error combination of lanthanide ions during the synthetic procedure. In this work we propose a simple and efficient method for the direct preparation of the desired material with the optimal combination of metal ions, avoiding the trial and error multiple synthetic approach. In the proposed strategy, the emission profiles of the isostructural complexes of each lanthanide ion for a chosen excitation wavelength are compared relative to their ion density and the necessary final composition of the material is calculated in order to obtain the white-light CIE coordinates. Using this method, we prepared a white-light emitting material which is a metal-organic framework built from oxydiacetate ligand, lanthanide ions (Eu, Tb and Dy emitting red, green and blue respectively) and zinc (a closed shell metal ion that has proven to be ideal for optical applications). The compound [Dy1.60Eu0.38Tb0.02Zn3(oda)6(H2O)6]·12H2O was prepared and fully characterized by single crystal x-ray diffraction, its optical properties were also measured. The proposed rational mixing of lanthanide ions could be useful for the preparation of white-light source materials in analogous systems, provided the single-lanthanide compounds are isostructural along the series and no optical interaction is operative among ions.

Abstract
A summary of the resource.
Workflows based on gas and liquid chromatography coupled to mass spectrometry for the identification of toxic pyrrolizidine alkaloids present in plants were developed and applied to Echium plantagineum L., Boraginaceae, extracts. GC–MS based determinations need reduction and derivatization steps prior to MS analysis, which is performed using a Full Scan and Single Ion Monitoring sequence for screening, identification and quantification purposes. The LC–(ESI)–MS/MS determination was performed directly from the extract without derivatization. Acetyl lycopsamine, echimidine, echimidine N-oxide, echiumine, echiumine N-oxide, lycopsamine, lycopsamine N-oxide, 7,9-ditigloylretronecine N-oxide and a not reported PA of m/z 466, were identified and quantified in E. plantagineum extracts, through three operating modes of LC-QTRAP: precursor ion scan, enhanced product ion scan and multiple reaction monitoring. Precursor ion scan detects all the ions that give rise to a daughter ion at m/z 120, the presence of the parent pyrrolizidine alkaloid is confirmed through its MS2 spectrum (enhanced product ion) and quantified by multiple reaction monitoring. These workflows are general approaches to study chemical families using GC/LC-MS. For extracts suspicious of containing pyrrolizidine alkaloids, they are suitable tools for the quality and safety control of food, feed as well as phytotherapeutics.

Abstract
A summary of the resource.
Lapachol acetate [systematic name: 3-(3-methyl­but-2-en­yl)-1,4-dioxonaph­thalen-2-yl acetate], C17H16O4, was prepared using a modified high-yield procedure and its crystal structure is reported for the first time 80 years after its first synthesis. The full spectroscopic characterization of the mol­ecule is reported. The mol­ecular conformation shows little difference with other lapachol derivatives and lapachol itself. The packing is directed by inter­molecular π–π and C—H...O inter­actions, as described by Hirshfeld surface analysis. The former inter­actions make the largest contributions to the total packing energy in a ratio of 2:1 with respect to the latter.

<strong>Ibogaine Administration Modifies GDNF and BDNF Expression in Brain Regions Involved in Mesocorticolimbic and Nigral Dopaminergic Circuits</strong>

Abstract
A summary of the resource.
Ibogaine is an atypical psychedelic alkaloid, which has been subject of research due to its reported ability to attenuate drug-seeking behavior. Recent work has suggested that ibogaine effects on alcohol self-administration in rats are related to the release of Glial cell Derived Neurotrophic Factor (GDNF) in the Ventral Tegmental Area (VTA), a mesencephalic region which hosts the soma of dopaminergic neurons. Although previous reports have shown ibogaine's ability to induce GDNF expression in rat midbrain, there are no studies addressing its effect on the expression of GDNF and other neurotrophic factors (NFs) such as Brain Derived Neurotrophic Factor (BDNF) or Nerve Growth Factor (NGF) in distinct brain regions containing dopaminergic neurons. In this work, we examined the effect of ibogaine acute administration on the expression of these NFs in the VTA, Prefrontal Cortex (PFC), Nucleus Accumbens (NAcc) and the Substantia Nigra (SN). Rats were i.p. treated with ibogaine 20 mg/kg (I20), 40 mg/kg (I40) or vehicle, and NFs expression was analyzed after 3 and 24 h. At 24 h an increase of the expression of the NFs transcripts was observed in a site and dose dependent manner. Only for I40, GDNF was selectively upregulated in the VTA and SN. Both doses elicited a large increase in the expression of BDNF transcripts in the NAcc, SN and PFC, while in the VTA a significant effect was found only for I40. Finally, NGF mRNA was upregulated in all regions after I40, while I20 showed a selective upregulation in PFC and VTA. Regarding protein levels, an increase of GDNF was observed in the VTA only for I40 but no significant increase for BDNF was found in all the studied areas. Interestingly, an increase of proBDNF was detected in the NAcc for both doses. These results show for the first time a selective increase of GDNF specifically in the VTA for I40 but not for I20 after 24 h of administration, which agrees with the effective dose found in previous self-administration studies in rodents. Further research is needed to understand the contribution of these changes to ibogaine's ability to attenuate drug-seeking behavior.

Abstract
A summary of the resource.
Studies exploring the effect of compounds that modulate the endocannabinoid system on sexual behavior have yielded contradictory results. However, the effect of smoked Cannabis in women has been consistently associated with an increase in sexual drive. Therefore, it can be speculated that vaporized Cannabis will augment sexually motivated components of the sexual behavior of female rats. To test this hypothesis, we compared the sexual behavior of late-proestrous female rats in a bilevel chamber after vaporizing 0, 200 or 400 mg of Cannabis flowers (containing 18% of delta-9-THC and undetectable levels of cannabidiol) during 10 min. We found that both doses of Cannabis increased the duration of the lordosis response, whereas the highest dose also reduced the lordosis quotient of females. The lowest dose of Cannabis augmented the display of hops and darts without altering the expression of sexual solicitations of females, while the highest one did not affect the expression of hops and darts but reduced sexual solicitations. These effects were not accompanied by alterations of females' ambulatory behavior. The increment of the duration of lordosis response produced by both doses of Cannabis could be associated to a general effect of this drug in sensory processing, as can be an enhancement of females' sensory reactivity to male's stimulation. However, the reduction in the display of solicitations and lordosis in response to mounting observed in females exposed to the highest dose when compared to control and 200 mg of Cannabis groups indicates a reduction of sexual receptivity and motivation. This differential effect of vaporized Cannabis according to the dose employed, suggests that it modulates sexual behavior in a complex way, impacting neural circuits that control different aspects of this social behavior.

Abstract
A summary of the resource.
In this work, we report a novel polymorph of AgBiW2O8, which was synthesized by a simple arc melting method. The structural details of this compound were determined by X-ray powder diffraction, and elemental composition was confirmed with ICP-AES. β-AgBiW2O8 adopts the scheelite structure type with tetragonal space group I41/a and lattice parameters a = b = 5.3019(3) and c = 11.678(2) Å. Structural details and optical properties are discussed in detail. Diffuse reflectance spectroscopy (DRS) measurements of β-AgBiW2O8 showed light absorption profile extended to the visible region, which suggests the material has a smaller band gap energy than Bi2WO6, as expected due to contribution of Ag d-orbitals to the electronic structure.

Abstract
A summary of the resource.
A novel method for the determination of trace cadmium in honey is presented. It consists of a preconcentration step based on dispersive liquid-liquid microextraction (DLLME) and measurement by flame AAS. Samples are dissolved in water. A mixture of carbon tetrachloride (extraction solvent) and acetonitrile (dispersion solvent) containing ammoniun pyrrolidine dithiocarbamate (APDC) as complexing agent is injected rapidly into the dissolved sample by means of a syringe pump. After centrifugation, an aliquot of the organic phase is injected in the nebuliser of an atomic absorption spectrometer by means of a lab-made microsampling device. Response (integrated absorbance) was linear with concentrations up to 12 μg L−1. Precision (sr(%)) at the 5 μg L−1 level was < 3.1%. Detection and quantification limits were 1.6 and 5.5 μg per 100 g of honey respectively. Six commercial samples were spiked at the 10 μg per 100 g level and analysed by the proposed method and by electrothermal atomic absorption spectrometry. The results did not differ at the 5% significance level, with recoveries for the DLLME/FAAS method ranging from 82 to 125%. The proposed method requires simple sample preparation and does not use expensive equipment, thus it could be used as screening method for the content of cadmium in honey.

Abstract
A summary of the resource.
Two novel multicomponent crystal forms of the prodrug 5-fluorocytosine (5-FC), an ionic cocrystal and a monohydrate salt, with 2,4,6-trinitrophenol (picric acid, PA) and 3,5-dinitrosalicylic acid (DNSA), respectively, were rationally designed and synthesized. Nitro compounds are used to treat many diseases, such as cancer, one of the 5-FC targets via gene-directed prodrug therapy. In addition, within the wide range of applications for nitro compounds is the formation of charge-transfer complexes with organic molecules. Among all 5-FC crystalline structures depicted, only two contain nitro compounds: a salt with PA and a dihydrate cocrystal with 5-nitrouracil. Therefore, the two new single translucent pale gold prism crystals of 5FC-PA and 5FC-DNSA were successfully obtained by slow evaporation from aqueous solution and characterized by X-ray diffraction (single crystal and powder), Fourier Transform Infrared (FT-IR), and Raman (FT-Raman) spectroscopies. In both crystal structures, the 5-FC pyrimidine ring is protonated at the N3 atom and the respective packings are mainly stabilized by N–H⋯O H-bonds. For the 5FC-PA ionic cocrystal, the formation of triple H-bonds (two N–H⋯O and one charge assisted N–H+⋯N H-bonds) among the 5-FC molecules was observed. This is consistent with the expected stability of the duplex structure, which is considered the strongest association between two species. In addition to the structural study, Hirshfeld surface analysis was carried out based on the single crystal X-ray diffraction data. Thermal stability was assessed through thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and hot-stage microscopy (HSM), indicating that these compounds are stable up to approximately 200 °C. The results contribute to the diversity of new 5-FC solid forms and introduce two novel compounds, with possible application in fungal/cancer medicine formulations or to better understand the behavior of cytosine in DNA/RNA base pairing.

Abstract
A summary of the resource.
The cupric reducing antioxidant capacity (CUPRAC) assay is an established procedure used to measure antioxidant content. Recently, the CUPRAC assay was adapted for use in post column derivatisation coupled with high performance liquid chromatography (HPLC-PCD). In prior works reported in the literature, CUPRAC HPLC-PCD assays used large post column mixing coils leading to a deterioration in the observed separation efficiency. In this work we used the CUPRAC PCD assay with reaction flow (RF) chromatography. No reaction loop was required, thus preserving the efficiency of the separation. We subsequently compared the performance of the CUPRAC assay to that of an antioxidant assay that we have previously converted to RF chromatography, namely the ferric reducing antioxidant potential (FRAP) assay, both in RF mode. The relative response factor with respect to trolox was measured for both RF assays via the separation of a standard mixture of 16 compounds. Sample analysis of coffee and green tea via both RF assays was used to compare their ability to screen for bioactive candidates in complex natural products. In general, the CUPRAC assay is recommended as the RF PCD methodology of choice as it provided a higher level of performance compared to the FRAP assay, demonstrating less baseline noise interference, greater sensitivity, wider linear dynamic range and better assay precision.

Abstract
A summary of the resource.
Herein, we predict the stability, structural and electronic properties of Janus-like boron arsenide (BAs) bilayer with the help of DFT calculations. We combine one hydrogenated and one fluorinated BAs layers in different stacking and arrangements. The interlayer charge transfer is also calculated and discussed with the help of various charge population mechanism. In addition to this, the choice of basis set is critical in determining the interlayer distances and consequently, the energy gaps. Additionally, the layer-resolved PDOS, at vdW-DF level, revealed that these bilayers are type-II semiconductors as the valence and conduction bands are composed of different layers. Furthermore, the band gap of these bilayers can efficiently be engineered from 0 to 0.54 eV by controlling the arrangement of the layers. That being said, the electronic properties can optionally be tuned from semiconducting to semimetallic. Additionally, the shape of the conduction band minima and the heavy-, light-hole bands provides the opportunity of utilization of these bilayers in ultrafast nanoelectronics.

Abstract
A summary of the resource.
We employ first‐principles DFT calculations to explore the potential use of BeN dual doped graphene (DDG) as an anode material for alkali‐based batteries. The introduction of BeN in graphene raise the adsorption of Li, Na, and K by 1.37 eV (2.23 times), 1.23 eV (2.83 times), and 1.14 eV (2.14 times), respectively. Furthermore, BeN DDG offers a modest energy barrier for alkali atoms studied. Moreover, the alkali atoms have good chemistry with Be and the interaction strength decreases during the migration toward N. Most importantly, the exceptional storage capacity of BeN DDG for Li (~2255 mAh/g), Na (~996 mAh/g), and K (~747 mAh/g) makes it a highly desirable anode material. Additionally, the average open circuit voltage offered for Li (0.66 V), Na (0.33 V), and (K = 1.10 V) is found to be in excellent range. All these outstanding properties provide the possibility of using BeN DDG in future alkali‐based batteries.

Abstract
A summary of the resource.
Herein, we perform DFT calculations to study the stability and the electronic and optical properties of pristine and hybrid bilayers of hexagonal boron phosphide (h-BP) and hexagonal boron arsenide (h-BAs). The electronic and optical properties of all bilayers can be modulated by the introduction of an external perpendicular electric field. Consequently, band gaps can be tuned from 0.8 eV down to zero as the field increases up to a critical value. Above this value, the gap reopens as the valence and conduction bands exhibit an anticrossing with a “Mexican-hat” shape, in a similar fashion to biased graphene bilayers. For the optical properties, we report an intense peak in the absorption spectra around 2.5–2.6 eV, with a slight blueshift as a function of electric field. Above the critical field, a new peak is observed in the infrared region which exhibits a strong field dependence. Additionally, this peak is related to the optical transitions around the “Mexican-hat” region of the band structure and the corresponding electron-hole pair shows a layer separation, which may lead to larger recombination times, a critical factor in photovoltaics. We believe that, with such tunable properties, these bilayers can find interesting applications in future devices in nanoelectronics and optoelectronics.

Abstract
A summary of the resource.
The adsorption of alkali atoms (Li, Na, and K) on graphene and hexagonal boron phosphide (h-BP) is studied by means of various density functionals including semi-local GGA, dispersion corrected DFT-D, meta-GGA, and many of the available non-local vdW-DF functionals. The accurate interaction energies are crucial for energy storage and battery applications as it is directly related to key properties in electrochemistry, such as storage capacities in general, and open circuit voltages (OCVs), in particular. A wider range of adsorption strength is predicted depending on the choice of non-local vdW-DF functionals. Furthermore, the performance of vdW-DF functionals was found to be independent of the choice of pseudopotentials used and especially if the choice is revPBE. Additionally, an excellent agreement is found between the Gaussian, VASP, and QE codes. Moreover, the h-BP is found to be an exceptional anode material for alkali batteries which can compete with any other available anode material. The small change in the adsorption energies as a function of increasing concentration of alkali atoms is a unique characteristic of h-BP. The exceptional 1283 mAh/g storage capacity not only for Li but in contrary with the previous study, also for Na in addition to the 642 mAh/g for K at vdW-DF/DZP level makes it a prominent candidate to be used as anode material. The average open circuit voltage for Li, Na, and K was also found to be in superb range. However, the values are found to be sensitive to the choice of functional, and in some cases, the storage capacity can be predicted as high as twice of the actual values. Therefore, the accurate description of the interaction is crucial and this study can be used to further refine the non-local DFT functionals. Moreover, by virtue of these properties, h-BP can be the best choice to be used as an anode material not only in LIBS but also in SIBs and KIBs.

Abstract
A summary of the resource.
We performed benchmark calculations to study the complexes of pyridine with beryllium, magnesium, and calcium. In all cases, the σ structures, in which the alkaline-earth element interacts with nitrogen, were found to be more stable than the ones featuring interactions with the π cloud. At the CCSD(T)/CBS level of theory, the dissociation energies (De) are 6.5, 3.7 and 7.2 kcal/mol, for beryllium, magnesium, and calcium, respectively. Our estimation of the D0 of the calcium-pyridine complex is in excellent agreement with the experimental value. For comparative purposes, we studied the performance of the M06-2X, PBE-D3BJ, vdW-DF, and B2PLYP-D2BJ density functionals. All of the DFT methods employed significantly overestimated the dissociation energies. Finally, in light of the results obtained, pyridinic nitrogen is the doping configuration to be chosen in nitrogen-doped graphene to improve the adsorption of alkaline-earth elements on this material.

Abstract
A summary of the resource.
The properties of mid-band-gap electronic states are central to the potential application of self-assembled, hybrid organic–inorganic perovskite-like quantum wells in optoelectronic technologies. We investigate broadband light emission from mid-band-gap states in fast-forming hybrid organic lead iodide quantum wells at room temperature. By comparing temperature- and intensity-dependent photoluminescence (PL) spectra emitted from butyl ammonium spaced inorganic layers, we propose that structural defects in a metastable material phase trap excitons and cause broadband light emission spanning wavelengths between 600 and 1000 nm. We use temperature-dependent terahertz time-domain spectroscopy to correlate changes in the subgap PL emission with changes in the chemical bonding of the inorganic octahedral layer. Our results provide new fundamental physical insights into the array of mechanisms capable of inducing broadband light emission from low-dimensional perovskite-like materials central to their application in future optoelectronic technologies and novel spectroscopic tools to characterize these states.

Abstract
A summary of the resource.
We investigate, by means of first‐principles density functional theory (DFT) calculation, the possibility of using hexagonal boron‐arsenide (h‐BAs) as an anode material for alkali‐based batteries. We show that the adsorption strength of alkali atoms (Li, Na, and K) on h‐BAs in comparison with graphene and other related materials changes a little as a function of alkali atom concentration. When the separation between alkali atoms and h‐BAs is less than the critical distance of ~5 Å, the adsorption energy abruptly increases showing fast adsorption without an energy barrier. Furthermore, the low energy barriers of 0.322, 0.187, and 0.0.095 eV for Li, Na, and K, respectively, ensure the fast ionic diffusivities for all the three alkali atoms. Additionally, the addition of these alkali atoms transforms the electronic properties of h‐BAs from semiconducting to metallic, resulting in improved electronic conductivities. Most interestingly, the excellent storage capacities of h‐BAs (~626 mAh/g) for alkali atoms make it a material of similar caliber to that of other popular anode materials. Finally, the average open circuit voltages are calculated and found to be in the desired range. In short, h‐BAs possess every quality that is crucial for an anode material and thus it is interesting to see h‐BAs in alkali‐based battery technologies.

Abstract
A summary of the resource.
First-principles density functional theory (DFT) calculations are performed to assess the stability, and geometric, mechanical, optical and electronic properties of monolayer graphene-like Be3N2. We find that Be3N2 is a large band gap semiconductor with small electron and hole effective masses, which may promote its use in nanoelectronic devices. Furthermore, its excellent thermal, dynamical, and mechanical stability makes it a material of comparable caliber to that of graphene. In addition, the excellent electrochemical properties of Be3N2 make it a unique material with possible theoretical capacities of 974 mA h g−1 for Li, Na, and K. Moreover, Be3N2 can form bulk graphite-like layered structures with two different configurations, i.e. N2–N1 and N2–Be1. Finally, the derivatives of Be3N2 (Be3N2 nanoribbons) also possess direct band gaps which can be finely tuned to the desired level by geometry and morphology constraints. Based on these fascinating properties, Be3N2 and its derivatives can find a broad range of applications in nanoelectronics and battery technologies.

Abstract
A summary of the resource.
Tocopherol separations employing the same Kinetex™ C18 column via supercritical fluid chromatography (SFC) and reversed-phase liquid chromatography (RP-LC) were compared. The application of the SFC system with UV diode array detection (DAD) resulted in rapid separation of all four tocopherol homologues with a total analysis time below 2 min. The RP-LC approach could not separate the isomers β and γ. The developed SFC-DAD method was precise, accurate, and most importantly more environmentally friendlier compared to the RP-LC method due to the 125-fold decrease in methanol consumption. The present study illustrated the selectivity differences between LC and SFC and how the C18 column can be used for tocopherol characterization. The optimized SFC method was successfully applied for the tocopherol determination in the seeds of nine different fruit species.

Abstract
A summary of the resource.
Angiotensin converting enzyme (ACE) plays a key role in regulating blood pressure and ACE inhibitors are first-line drugs for treating hypertension. Food protein-derived peptides with ACE inhibitory activity are natural and safe alternatives for both prevention and treatment of hypertension. The second most abundant whey protein, α-lactalbumin (ALA) was hydrolysed with proteases from Bromelia antiacantha Bertol., a native plant. Two new peptides with potent ACE-inhibitory activity: TTFHTSGY (IC50 = 142 μM) and GYDTQAIVQ (IC50 = 1.0 mM) were purified by affinity chromatography and sequences were determined by mass spectrometry. In silico analysis indicated that neither of these peptides was toxic (ToxinPred). Inhibition kinetic analysis showed that TTFHTSGY was a fully functional ACE competitive inhibitor, whereas GYDTQAIVQ caused only partial ACE inhibition. Our results indicate that cysteine peptidases from B. antiacantha hydrolyse ALA to produce novel ACE inhibitory peptides that could be useful even as functional food ingredients.

Background: The production of recombinant proteins in mammalian cell lines is one of the most important areas in biopharmaceutical industry. Viral transcriptional promoters are widely used to express recombinant proteins in mammalian cell lines. However, these promoters are susceptible to silencing, thus limiting protein productivity. Some CpG islands can avoid the silencing of housekeeping genes; for that reason, they have been used to increase the production of recombinant genes in cells of animal origin. In this study, we evaluated the CpG island of the promoter region of the β-actin gene of Cricetulus griseous (Chinese hamster), associated to the Cytomegalovirus (CMV) promoter, to increase recombinant antibodies production in Chinese Hamster Ovary (CHO) cells. Results: We focused on the non-coding region of CpG island, which we called RegCG. RegCG behaved as a promoter, whose transcriptional activity was mainly commanded by the CAAT and CArG boxes of the proximal promoter. However, the transcription started mainly at the intronic region before the proximal transcription start site. While the CMV promoter was initially more powerful than RegCG, the latter promoter was more resistant to silencing than the CMV promoter in stable cell lines, and its activity was improved when combined with the CMV promoter. Thereby, the chimeric promoter was able to maintain the expression of recombinant antibodies in stable clones for 40 days at an average level 4 times higher than the CMV promoter. Finally, the chimeric promoter showed compatibility with a genetic amplification system by induction with methotrexate in cells deficient in the dihydrofolate reductase gene. Conclusions: We have generated an efficient synthetic hybrid transcription promoter through the combination of RegCG with CMV, which, in stable cell lines, shows greater activity than when both promoters are used separately. Our chimeric promoter is compatible with a genetic amplification system in CHO DG44 cells and makes possible the generation of stable cell lines with high production of recombinant antibodies. We propose that this promoter can be a good alternative for the generation of clones expressing high amount of recombinant proteins, essential for industrial applications.

Abstract
A summary of the resource.
The objective of this work was to investigate the effect of the addition of carboxymethyl chitosan on the structural properties and antilisterial activity of nisin-incorporated chitosan films. Chitosan and carboxymethyl chitosan solutions were prepared with different mass ratios and bacteriocin nisin was added (0, 1000 and 6000 IU/ml). Filmogenic solutions were cast, dried and their physico-chemical and antimicrobial properties were investigated. For the same chitosan/carboxymethyl chitosan mass ratio, the addition of NIS at 6000 IU/ml led to changes in the macro- and microstructure, as well as in physico-chemical properties of films. On the other hand, carboxymethyl chitosan had a plasticizing effect and enhanced the distribution of the bacteriocin within the biopolymer matrix. Moreover, nisin-incorporated blend films of chitosan and carboxymethyl chitosan were more effective against Listeria monocytogenes than their pure chitosan counterparts. This study showed that different formulations of nisin-incorporated composite films of chitosan and carboxymethyl chitosan may provide options for developing bioactive packaging to improve food safety.
