Effect of cocoa roasting time on volatile composition of dark chocolates from different origins determined by HS-SPME/GC-MS

In this study the volatile composition of six samples of dark chocolates varying in the cocoa roasting time (30.5, 34.5 and 38.5 min) and geographical origin (Ecuador and Ghana) was characterized by headspace solid-phase microextraction (HS-SPME) followed by gas chromatography-mass spectrometry (GC-MS). One hundred and twenty-one different compounds were identified using a carboxen/polydimethylsiloxane (CAR-PDMS) fiber comprising acids, alcohols, aldehydes, alkanes, esters, furans, ketones, nitrogen compounds, pyran derivatives, pyrazines, pyrroles and thiazoles. The effect of roasting time on the volatile composition of chocolates depended on their geographical origin. Principal component analysis (PCA) was applied to volatile composition of the six dark chocolate samples. Eight different groups of compounds were established according to the position of the aroma compounds on the PC plot and accordingly to variation among samples. Therefore, volatile compounds that appeared or disappeared during roasting of cocoa from each origin or both origins were identified.

New Aspects of Monoamine Oxidase B Inhibitors: The Key Role of Halogens to Open the Golden Door

A large plethora of drugs and promising lead compounds contain halogens in their struc-tures. The introduction of such moieties strongly modulates their physical-chemical features as well as pharmacokinetic and pharmacodynamic profile. The most important outcome was shown to be the ability of these halogens to favourably influence the drug-target interaction and energetic stability within the active site by the establishment of halogen bonds. This review attempted to demonstrate the key role exerted by these versatile moieties when correctly located in an organic scaffold to display Monoamine Oxidase (MAO) inhibition and selectivity towards the B isoform of this important enzyme. Human MAOs are well-recognized as therapeutic targets for mood disorders and neurodegenerative diseases and medicinal chemists were prompted to discover the structural requirements crucial to discriminate the slight differences between the active sits of the two isoforms (MAO-A and MAO-B). The analysis of the structure-activity relationships of the most important scaffolds (hydrazothia- zoles, coumarins, chromones, chalcones, pyrazolines) and the impact of halogen (F, Cl, Br and I) insertion on this biological activity and isozyme selectivity have been reported being a source of inspiration for the medicinal chemists.

Synthesis, molecular docking and ADME studies of thiazole-thiazolidinedione hybrids as antimicrobial agents

New thiazole-thiazolidinedione hybrids (5a-k) were efficiently synthesized and evaluated for their in-vitro antimicrobial activity against four fungal and bacterial strains. The chemical structures of the compounds were elucidated by FTIR, H-1 NMR, and C-13 NMR spectral data. Most of the synthesized compounds were sensitive against gram positive, gram negative bacterial and fungal strains. Among the synthesized molecules, compounds 5h, and 5i exhibited promising inhibitory activity against all selected fungal strains and gram positive bacteria namely, Staphylococcus aureus, and Enterococcus faecalis. The molecular docking results predicted that the thiazole-thiazolidinedione derivatives bind to the active site protein ATP-binding pocket from E. coli, S. aureus and C. albicans with good interaction energy scores. Ct-DNA was used to evaluate the binding interactions of the selected compounds by means of absorption spectroscopy. To further characterize the drug-likeness and ADME properties were calculated using the Qikprop, the result of present study suggests that thiazole-thiazolidinedione hybrid could be an interesting approach for the design of new antimicrobial agents.

Breaking the axiality of pentagonal-bipyramidal dysprosium(iii) single-molecule magnets with pyrazolate ligands

A range of pyrazolate-based ligands have been used to balance the multidentate-chelating feature and the magnetic axiality in destroyed pentagonal-bipyramidal (DPB) dysprosium(iii) single-molecule magnets (SMMs). This family of complexes are air-stable and share the general formulae of [(DyXX2)-X-1(L-eq)(5)][BPh4], where X-1 and X-2 are the anionic axial ligands, including pyrazolate-based ligands and chloride; L-eq is the equatorial solvent molecule such as tetrahydrofuran (THF), pyridine (py) and thiazole (NS). Compared to the prototype PB SMMs, the bidentate-chelating features of the pyrazolate ligands show, albeit slow magnetic relaxation behavior, a much smaller energy barrier for magnetization reversal (U-eff). Static electronic calculation shows that the magnetic axiality above the ground m(J) = +/- 15/2 states has been much reduced, leading to the mixing of other states at higher levels. Nevertheless, this systematic study reveals that the variation of the substituents on the pyrazolate ligands and the replacement of planar solvents are effective at influencing the magnetic relaxation behavior. We found that the chloride coordinating mono-pyrazolate complexes, such as [(DyXCl)-Cl-1(THF)(5)][BPh4] (X-1 = 3-(trifluoromethyl)pyrazole (tfpz) 1, X-1 = 3-methylpyrazole (Mepz) 2, X-1 = 3-isopropyl-1H-pyrazole (Iprpz) 3, X-1 = 3,5-dimethylpyrazole (Me(2)pz) 4, X-1 = 3,5-diisopropylpyrazole (Ipr(2)pz) 5, and X-1 = pyrazole (pz) 6, generally show lower U-eff, while bi-pyrazolate complexes, such as [Dy(tfpz)(2)(THF)(5)][BPh4] 7, [Dy(pz)(2)(THF)(5)][BPh4] 8, [Dy(pz)(2)(py)(5)][BPh4]center dot 2py 9 and [Dy(pz)(2)(NS)(5)][BPh4] 10, show higher U-eff. Among them, 8 shows the largest U-eff of 521(8) K and a comparable open hysteresis temperature of similar to 5 K (at a field sweeping rate of 12 Oe s(-1)) with 9 and 10. The enhanced blocking temperature for 8 is different from that for the PB Dy(iii) SMMs in which the py ligand can cause a much higher hysteresis temperature than the one coordinated with THF due to the aromatic pi-pi interactions, indicating that the bis-bidentate-chelating Dy(iii) ion is rigid enough to reduce the influence from the equatorial ligands. Moreover, substitution with electron-withdrawing groups such as the -CF3 group reduces U-eff prominently. Such a clear magnetostructural correlation in Dy(iii) SMMs is fundamentally important, indicating that a subtle balance between magnetic axiality and molecular rigidity is critical to design high-performance Dy(iii) SMMs.

A combine approach of chemical synthesis, biological evaluation and structural dynamics studies revealed thiazole substituted arylamine derivatives as potent FabH enzyme inhibitors

Bacterial FabH enzyme is a broad-spectrum antimicrobial target and can be used in the design of novel antibiotics. This study reports chemical synthesis of thiazole based amine compounds as FabH inhibitors, followed by biological evaluation, and computational drug designing analysis with ultimate objective to guide further biological optimization of the identified hits. The compounds were synthesized through Pd-PEPPSI catalyzed cross coupling strategy for the Buchwald-Hartwig amination of thiazole-substituted aryl bromide. Pd-PEPPSI pre catalysts were utilized for the cross couple with the diverse range of functionalized electron-deficient and electron-rich anilines and aliphatic amines. The thiazole based heteroaryl bromide coupling was found to be challenging and only specialized Pd-PEPPSI-IPr and Pd-PEPPSI-IPent catalysts were found to be effective providing the coupling product yield in the range of 78% to 99%. Biological investigation depicted compound 3f to be effective against Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermis, and Escherichia coli with mean + standard deviation value of 9.6 +/- 0.4, 11.6 +/- 0.4, 15.6 +/- 0.4, and 11.6 +/- 0.4, respectively. This compound is also active against free radicals with EC90 value of 39.45 mu g/ml. Comparative docking predictions unravel the 3f binding mode at FabH active tunnel as such to block complete access for the natural substrate and involved balanced hydrogen and hydrophobic interactions. FabH-3f complex dynamics in solution found the docked conformation between the protein and compound of higher stability with mean carbon alpha deviation of 1.87 angstrom and mean residual deviation of 0.88 angstrom. Intermolecular interactions analysis depicted Asn274 from FabH active pocket to be significant in compound holding and strengthening of interaction as the simulation progresses. This was supported further by radial distribution function (RDF) and axial frequency distribution (AFD) that demonstrated the high distribution of compound atoms in close proximity of Asn274 residue and decrease in interaction distance. Further, the docking and simulation findings were validated through MMPB/GBSA methods that complements the compound affinity for the said target. In a nutshell, the identified hit could be subjected to structure, biological and pharmacokinetic optimization for development of effective FabH inhibitors.

High temperature membranes based on PBI/sulfonated polyimide and doped-perovskite nanoparticles for PEM fuel cells

A new sulfonated aromatic diamine monomer containing nitrogen heterocycles was synthesized and employed to prepare a novel sulfonated polyimide (SPI). To develop proton exchange membranes, new nanocomposite blend membranes consist of the prepared SPI and polybenzimidazole (PBI) were fabricated with incorporation of SrCe0.9Yb0.1O3-delta (SCYb) doped-perovskite nanoparticles with a solution-casting method. The goal of this work is to study the effect of SPI and SCYb doped-perovskite nanoparticles on the important parameters of the PBI membrane specially proton conductivity and fuel cell performance. The proton conductivity and phosphoric acid doping level of the PBI-SPI-SCYb nanocomposite blend membranes improved due to an interaction of -SO3H group and thiazole rings of SPI and N-H groups of PBI in the oxygen vacancies of SCYb doped-perovskite nanoparticles. Substitution of Ce4+ by Yb3+ in the SCYb doped-perovskite nanoparticles produce oxygen vacancies and decrease the columbic repulsion between protons and positive ions. Furthermore at highest phosphoric acid doping level of 14 mol phosphoric acid per monomer unit, the nanocomposite blend membranes displayed proton conductivity of 131 mS/cm at 180 degrees C and 8% relative humidity. The increase in power density from 0.31 W/cm(2) in PBI-SPI blend membranes (SPI/PBI: 25 wt%) to 0.59 W/cm(2) in PBI-SPI-SCYb nanocomposite blend membranes (SPI/PBI: 25 wt% and 7 wt% of SCYb) was achieved at 0.5 V, 8% RH and 180 degrees C, which demonstrates that these developed nanocomposite blend membranes have a high potential to be regarded as the most promising candidates for high-temperature fuel cell with improved proton conductivity.
