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.

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.

Efficient Method for the Concentration Determination of Fmoc Groups Incorporated in the Core-Shell Materials by Fmoc-Glycine

In this paper, we described the synthesis procedure of TiO2@SiO(2)core-shell modified with 3-(aminopropyl)trimethoxysilane (APTMS). The chemical attachment of Fmoc-glycine (Fmoc-Gly-OH) at the surface of the core-shell structure was performed to determine the amount of active amino groups on the basis of the amount of Fmoc group calculation. We characterized nanostructures using various methods: transmission electron microscope (TEM), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and X-ray photoelectron spectroscopy (XPS) to confirm the modification effectiveness. The ultraviolet-visible spectroscopy (UV-vis) measurement was adopted for the quantitative determination of amino groups present on the TiO2@SiO(2)core-shell surface by determination of Fmoc substitution. The nanomaterials were functionalized by Fmoc-Gly-OH and then the fluorenylmethyloxycarbonyl (Fmoc) group was cleaved using 20% (v/v) solution of piperidine in DMF. This reaction led to the formation of a dibenzofulvene-piperidine adduct enabling the estimation of free Fmoc groups by measurement the maximum absorption at 289 and 301 nm using UV-vis spectroscopy. The calculations of Fmoc loading on core-shell materials was performed using different molar absorption coefficient: 5800 and 6089 dm(3)x mol(-1)x cm(-1)for lambda = 289 nm and both 7800 and 8021 dm(3)x mol(-1)x cm(-1)for lambda = 301 nm. The obtained results indicate that amount of Fmoc groups present on TiO2@SiO2-(CH2)(3)-NH(2)was calculated at 6 to 9 mu mol/g. Furthermore, all measurements were compared with Fmoc-Gly-OH used as the model sample.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 13925-03-6 help many people in the next few years. Recommanded Product: 13925-03-6.

Synthesis and Modeling Studies of Furoxan Coupled Spiro-Isoquinolino Piperidine Derivatives as NO Releasing PDE 5 Inhibitors

Nitric oxide (NO) is considered to be one of the most important intracellular messengers that play an active role as neurotransmitter in regulation of various cardiovascular physiological and pathological processes. Nitric oxide (NO) is a major factor in penile erectile function. NO exerts a relaxing action on corpus cavernosum and penile arteries by activating smooth muscle soluble guanylate cyclase and increasing the intracellular concentration of cyclic guanosine monophosphate (cGMP). Phophodiesterase (PDE) inhibitors have potential therapeutic applications. NO hybridization has been found to improve and extend the pharmacological properties of the parental compound. The present study describes the synthesis of novel furoxan coupled spiro-isoquinolino-piperidine derivatives and their smooth muscle relaxant activity. The study reveals that, particularly 10d (1.50 +/- 0.6) and 10g (1.65 +/- 0.7) are moderate PDE 5 inhibitors as compared to Sidenafil (1.43 +/- 0.5). The observed effect was explained by molecular modelling studies on phosphodiesterase.

Pathway enrichment analysis of virus-host interactome and prioritization of novel compounds targeting the spike glycoprotein receptor binding domain-human angiotensin-converting enzyme 2 interface to combat SARS-CoV-2

SARS-CoV-2 has become a pandemic causing a serious global health concern. The absence of effective drugs for treatment of the disease has caused its rapid spread on a global scale. Similarly to the SARS-CoV, the SARS-CoV-2 is also involved in a complex interplay with the host cells. This infection is characterized by a diffused alveolar damage consistent with the Acute Respiratory Disease Syndrome (ARDS). To explore the complex mechanisms of the disease at the system level, we used a network medicine tools approach. The protein-protein interactions (PPIs) between the SARS-CoV and the associated human cell proteins are crucial for the viral pathogenesis. Since the cellular entry of SARS-CoV-2 is accomplished by binding of the spike glycoprotein binding domain (RBD) to the human angiotensin-converting enzyme 2 (hACE2), a molecule that can bind to the spike RDB-hACE2 interface could block the virus entry. Here, we performed a virtual screening of 55 compounds to identify potential molecules that can bind to the spike glycoprotein and spike-ACE2 complex interface. It was found that the compound ethyl 1-{3-[(2,4-dichlorobenzyl) carbamoyl]-1-ethyl-6-fluoro-4-oxo-1,4-dihydro-7-quinolinyl}-4-piperidine carboxylate (the S54 ligand) and ethyl 1-{3-[(2,4-dichlorobenzyl) carbamoyl]-1-ethyl-6-fluoro-4-oxo-1,4-dihydro-7-quinolinyl}-4 piperazine carboxylate (the S55 ligand) forms hydrophobic interactions with Tyr41A, Tyr505B and Tyr553B, Leu29A, Phe495B, respectively of the spike glycoprotein, the hotspot residues in the spike glycoprotein RBD-hACE2 binding interface. Furthermore, molecular dynamics simulations and free energy calculations using the MM-GBSA method showed that the S54 ligand is a stronger binder than a known SARS-CoV spike inhibitor SSAA09E3 (N-(9,10-dioxo-9, 10-dihydroanthracen-2-yl) benzamide).

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 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.

Anti-MRSA (Multidrug Resistant Staphylococcus aureus) Activity of 3-Substituted Coumarins

Background: Infectious pathogenic bacteria are the key virulence in our daily life. Especially diseases produced by multidrug resistant Staphylococcus aureus (MRSA) still contributing in morbidity and mortality in humans. Discovery of new and safer antibiotics is an upmost task in current medicinal research. Methods: By keeping in mind the considerable antimicrobial activities of coumarin scaffold, 3-substituted coumarin derivatives 1-24 were synthesized by Knoevenegel condensation reaction. Different aryl aldehydes were treated with beta-keto esters in the presence of organic base piperidine. All synthetic compounds were characterized by different spectroscopic techniques such as EI-MS, HREI-MS, H-1-NMR, and C-13-NMR. Compounds were screened to check for their in vitro anti-MRSA (multidrug resistant Staphylococcus aureus) activity against different strains of bacteria such as MRSA-252, EMRSA-16, EMRSA-17 and local clinical isolate. Micro-plate alamar blue assay (MABA) was used for this activity. Oxacillin, streptomycin, clindamycin and vancomycin were used as standards. Results: Results were reported as percent inhibition at 20 mu g/mL concentration. Amongst all four standard drugs, only vancomycin was showed 19%, 24%, 21% and 40% inhibitions in case of MRSA-252, EMRSA-16, EMRSA-17 and local clinical isolate, respectively, at 20 mu g/mL concentration. Most of the synthetic compounds were showed a weak to good inhibition as compared to standard, vancomycin. Conclusion: Newly identified compounds may serve as lead for future research in order to get the more powerful antibacterial agents.

Dual Target Ligands with 4-tert-Butylphenoxy Scaffold as Histamine H-3 Receptor Antagonists and Monoamine Oxidase B Inhibitors

Dual target ligands are a promising concept for the treatment of Parkinson’s disease (PD). A combination of monoamine oxidase B (MAO B) inhibition with histamine H-3 receptor (H3R) antagonism could have positive effects on dopamine regulation. Thus, a series of twenty-seven 4-tert-butylphenoxyalkoxyamines were designed as potential dual-target ligands for PD based on the structure of 1-(3-(4-tert-butylphenoxy)propyl)piperidine (DL76). Probed modifications included the introduction of different cyclic amines and elongation of the alkyl chain. Synthesized compounds were investigated for human H3R (hH(3)R) affinity and human MAO B (hMAO B) inhibitory activity. Most compounds showed good hH(3)R affinities with K-i values below 400 nM, and some of them showed potent inhibitory activity for hMAO B with IC50 values below 50 nM. However, the most balanced activity against both biological targets showed DL76 (hH(3)R: K-i = 38 nM and hMAO B: IC50 = 48 nM). Thus, DL76 was chosen for further studies, revealing the nontoxic nature of DL76 in HEK293 and neuroblastoma SH-SY5Ycells. However, no neuroprotective effect was observed for DL76 in hydrogen peroxide-treated neuroblastoma SH-SY5Y cells. Furthermore, in vivo studies showed antiparkinsonian activity of DL76 in haloperidol-induced catalepsy (Cross Leg Position Test) at a dose of 50 mg/kg body weight.

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.
