Distribution of furanyl fentanyl and 4-ANPP in an accidental acute death: A case report

Fatalities from emerging synthetic opioids have continued to reach new epidemic proportions throughout the world in recent years. Due to the sparsity of research in new opioid analogs, commonly observed lethal concentrations and their distribution following death have yet to be well documented. The prevalence of furanyl fentanyl in postmortem casework contributes to the opioid related deaths that are amongst half of drug-induced fatalities in the United States. In this case study, a 23-year-old man was found dead in San Francisco following the ingestion of blue pills imitating oxycodone. Initial toxicology screening did not detect oxycodone in blood. However, a positive fentanyl immunoassay result was obtained and analysis of the pills collected at the scene showed the presence of furanyl fentanyl. Analysis of postmortem samples revealed concentrations of furanyl fentanyl at 1.9 ng/mL in peripheral blood, 2.8 ng/mL in cardiac blood, and similar to 55,000 ng in gastric contents. Metabolite 4-anilino-N-phenethyl-piperidine (4-ANPP) was also confirmed at 4.3 ng/mL and 5.8 ng/mL in peripheral blood and cardiac blood, respectively. Trace amounts of both analytes were detected in urine and the vitreous humor. Liver 4-ANPP concentrations of >40 ng/g were also detected. This case study of acute furanyl fentanyl overdose in a young male thought to be using oxycodone highlights illicit drug users are often subject to unknown drug entities. The toxicological analysis provides preliminary information of the distribution of furanyl fentanyl and its metabolite in a range of postmortem specimens and collection sites. (c) 2017 Elsevier B.V.

The potential contribution of the natural products from Brazilian biodiversity to bioeconomy

The development of our society has been based on the use of biodiversity, especially for medicines and nutrition. Brazil is the nation with the largest biodiversity in the world accounting for more than 15% of all living species. The devastation of biodiversity in Brazil is critical and may not only cause the loss of species and genes that encode enzymes involved in the complex metabolism of organisms, but also the loss of a rich chemical diversity, which is a potential source for bioeconomy based on natural products and new synthetic derivatives. Bioeconomy focus on the use of bio-based products, instead of fossil-based ones and could address some of the important challenges faced by society. Considering the chemical and biological diversity of Brazil, this review highlights the Brazilian natural products that were successfully used to develop new products and the value of secondary metabolites from Brazilian biodiversity with potential application for new products and technologies. Additionally, we would like to address the importance of new technologies and scientific programs to support preservation policies, bioeconomy and strategies for the sustainable use of biodiversity.

Metal-Free Carbonylation Route to a Reactive Borataepoxide System

Hydroboration of N-allyl-cis-2,6-dimethylpiperidine with HB(C6F5)(2) gave the trimethylene-bridged frustrated N/B Lewis pair 7. It featured a trans-2,6-dimethyl substitution pattern at the piperidine unit which indicated preceding equilibration with its iminium cation/hydridoborate isomer 6 by means of an internal hydride transfer. In situ generated compound 6 is essential for the reaction with CO/HB(C6F3)(2) to give the borataepoxide product 12 at the [N]-(CH2)(3)-[B] framework. The borataepoxide 12 reacts rapidly with CO2, cleaves the acidic C-H bond of a terminal alkyne, splits dihydrogen, and reacts with nitriles and benzaldehyde. Most products were characterized by X-ray diffraction.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 188111-79-7 is helpful to your research. Recommanded Product: 188111-79-7.

Diversity of Secondary Metabolites in Roots from Conium maculatum L.

Background:Conium maculatumis known as highly toxic plant, due to piperidine alkaloids present in the aerial parts. In a first attempt, in various tap root samples, however, alkaloids could not be detected. The present study describes active compounds in the tap roots from 16 populations harvested at maturity. The compounds were extracted with dichloromethane from root pieces of single plants and analyzed by gas chromatography-mass spectrometry. Ten bioactive compounds were evaluated: five furocoumarins, two prenylated coumarins, two aliphatic C-17-polyacetylenes and the phenylpropanoid elemicin. A high variability could be observed, the highest concentrations were measured for falcarindiol, xanthotoxin and isopimpinellin, the lowest for elemicin. In sumC. maculatumroots contained comparable amounts of compounds that are characteristic for Apiaceae, and also occur in vegetables as carrots, parsnip, parsley or celeriac.

The Effect of Strength of Bases and Temperature on the Synthesis of Zn-Al Layered Double Hydroxides by a Non-Aqueous ‘Soft Chemical’ Sol-Gel Method and Formation of High Surface Area Mesoporous ZnAl2O4 Spinel

Layered double hydroxides are the 2D layered material also known as the anionic clays having the general formula [M-1-x(2+) M-x(3+) (OH)(2) ](x+) [A(x/n)](n) center dot m H2O where different M2+ ions such as Zn2+, Ni2+, Mg2+, Co2+ and M(3+ )ions such as Al3+, Cr3+, Ga3+, In3+, Mn3+, Fe3+ are uniformly distributed and orderly pre-arranged in the brucite-like sheets and various charge- compensating anions (A(n- )= CO32-, NO3-, Cl- , OH-) are present in their interlayer spaces along with the water molecules. During the synthesis of Zn-Al layered double hydroxides by non aqueous soft chemical method the strength of bases as well as the temperature influences immensely the hydrolysis of Zinc acetylacetonate (Zn(acac)(2)) and Aluminium acetylacetonate (Al(acac)(2)). Different bases such as sodium hydroxide (NaOH), piperidine, diethylamine and ammonia (NH3) was used and it was found that Zinc acetylacetonate (Zn(acac)(2)) directly forms Zincite (ZnO) phase without reacting with Aluminium acetylacetonate (Al(acac)(3)) at temperature of around 80 degrees C. When the temperature was decreased to 0 degrees C from room temperature as well as side by side the strength of bases were increased the formation of Zincite (ZnO) phases reduced. Thus, Zn-Al layered double hydroxide could only be synthesized at 0 degrees C and in presence of stronger bases like sodium hydroxide (NaOH) and piperidine. The X-ray diffraction analysis showed the presence of low intensity Zincite (ZnO) phases in Zn-Al layered double hydroxide synthesized in presence of sodium hydroxide (NaOH) which was absent in presence of piperidine. Zn-Al layered double hydroxide synthesized were further characterized by thermal analysis (TGA-DTA), Infrared spectroscopy (FTIR), Scanning electron microscopic and energy dispersive X-ray spectroscopic (SEM-EDS) analysis, Brunauer-Emmett-Teller (BET) surface area and pore diameter analysis which showed their different characteristics as the base is changed. Zn-Al layered double hydroxide synthesized in presence of piperidine after thermal treatment at 800 degrees C formed high surface area mesoporous flower platelet like Zinc-Aluminium Oxide (ZnAl2O4) spinel which have surface area of 124.8 m(2)g(-1 )and mesopores of dimensions about 5-20 nm respectively.

One pot synthesis, physicochemical and photophysical investigation of biologically active pyridine-3-carboxylate (ECPC) as probe to determine CMC of surfactants in organized media

Ethyl 4 – (9-ethyl-9H-carbazol-3-yl) – 2 – methyl – 5- oxo – 4, 5 – dihydro-1H-indeno[1,2-b]pyridine-3-carboxylate (ECPC) was prepared by one pot multi component reaction of 9-ethyl-9H-carbazole-3-carbaldehyde, indane-1,3-dione, ethyl acetoacetate and ammonium acetate in the presence few drops of piperidine. Structure of the title compound (ECPC) was confirmed by the spectroscopic techniques (FT-IR, H-1-NMR, C-13-NMR, EI-MS) and elemental analysis. Photophysical parameter of the ECPC such as transition dipole moment, extinction coefficient, stokes shift, oscillator strength, fluorescence quantum yield were calculated by using the different solvents (based on the polarity). The results of compound ECPC showed red shift in absorbance and emission spectrum with increase in the polarity of the solvents from n-heptane to DMSO. Emission spectrum of ECPC effected with anionic and cationic surfactant so ECPC can be used as probe to determine critical micelle concentrations (CMC) of anionic sodium dodecyl sulfate (SDS) and cationic cetyltrimethylammonium bromide (CTAB) surfactant. The in-vitro antibacterial activity of ECPC was examined by the disk diffusion and minimum inhibitory concentration (MIC) methods against two Gram-positive and two Gram-negative bacteria by using Tetracycline as reference drug.

Alkaloid-Rich Crude Extracts, Fractions and Piperamide Alkaloids of Piper guineense Possess Promising Antibacterial Effects

Piper guineense is a food and medicinal plant commonly used to treat infectious diseases in West-African traditional medicine. In a bid to identify new antibacterial compounds due to bacterial resistance to antibiotics, twelve extracts of P. guineense fruits and leaves, obtained by sequential extraction, as well as the piperine and piperlongumine commercial compounds were evaluated for antibacterial activity against human pathogenic bacteria. HPLC-DAD and UHPLC/Q-TOF MS analysis were conducted to characterize and identify the compounds present in the extracts with promising antibacterial activity. The extracts, with the exception of the hot water decoctions and macerations, contained piperamide alkaloids as their main constituents. Piperine, dihydropiperine, piperylin, dihydropiperylin or piperlonguminine, dihydropiperlonguminine, wisanine, dihydrowisanine and derivatives of piperine and piperidine were identified in a hexane extract of the leaf. In addition, some new piperamide alkaloids were identified, such as a piperine and a piperidine alkaloid derivative and two unknown piperamide alkaloids. To the best of our knowledge, there are no piperamides reported in the literature with similar UV absorption maxima and masses. A piperamide alkaloid-rich hexane leaf extract recorded the lowest MIC of 19 mu g/mL against Sarcina sp. and gave promising growth inhibitory effects against S. aureus and E. aerogenes as well, inhibiting the growth of both bacteria with a MIC of 78 mu g/mL. Moreover, this is the first report of the antibacterial activity of P. guineense extracts against Sarcina sp. and E. aerogenes. Marked growth inhibition was also obtained for chloroform extracts of the leaves and fruits against P. aeruginosa with a MIC value of 78 mu g/mL. Piperine and piperlongumine were active against E. aerogenes, S. aureus, E. coli, S. enterica, P. mirabilis and B. cereus with MIC values ranging from 39-1250 mu g/mL. Notably, the water extracts, which were almost devoid of piperamide alkaloids, were not active against the bacterial strains. Our results demonstrate that P. guineense contains antibacterial alkaloids that could be relevant for the discovery of new natural antibiotics.

Structure-directed formation of the dative/covalent bonds in complexes with C70MIDLINE HORIZONTAL ELLIPSISpiperidine

The combined experimental-computational study has been performed to investigate the complexes formed between C-70 carbon allotrope and piperidine. The results of FT-IR, H-NMR, and C-NMR measurements, together with the calculations based on the DFT approach and molecular dynamics simulations, prove the existence of dative/covalent bonding in C70MIDLINE HORIZONTAL ELLIPSISpiperidine complexes. The dative bond forms not only at the region of five- and six-membered rings, observed previously with C-60, but also at the region formed of six-membered rings. The structure, i.e., nonplanarity, explains the observed dative bond formation. New findings on the character of interaction of secondary amines with C-70 bring new aspects for the rational design of modified fullerenes and their applications in electrocatalysis, spintronics, and energy storage.
