Mixed-ligand complexes of tenoxicam drug with some transition metal ions in presence of 2,2 ‘-bipyridine: Synthesis, spectroscopic characterization, thermal analysis, density functional theory and in vitro cytotoxic activity

The Preparation and characterization of Cr(III), Fe(III), Co(II), Ni(II), Cu(II) and Y(III) mixed ligand metal complexes with the effective anti-inflammatory drug tenoxicam (Ten) and 2,2’-bipyridine (Bipy) have been informed in this study by using elemental analyses, FT-IR, UV-Vis., H-1 NMR, mass spectra, thermal analyses (TGA, DTG), molar conductance and magnetic moment. FT-IR and UV-Vis. spectra proved that Ten acts as a neutral bidentate ligand chelated to the metal ions via the pyridine-N and oxygen of carbonyl group of the amide moiety and Bipy chelated through the nitrogen atoms. The thermodynamic parameters (E*, Delta S*, Delta H* and Delta G*) were calculated by using Coats-Redfern and Horowitz- Metzger method from DTG curves. The antimicrobial activity for all compounds against various species of bacteria and fungi was investigated and the results ensured that Fe(III) complex is more active than all other complexes. The DFT calculations were carried out to understand the optimized molecular geometry for the compounds. All studied complexes considered as soft respect to the Ten, with G value varied from 11.236 to 16.949 eV and equal to 8.772eV for Ten. The anticancer activity was screened against cell culture of HCT-116 (human colorectal carcinoma), HepG2 (human hepatocellular carcinoma) and MCF-7 (human breast adenocarcinoma) for all compounds.

Carbon input manipulations affecting microbial carbon metabolism in temperate forest soils – A comparative study between broadleaf and coniferous plantations

Large uncertainties exist about the relative importance of aboveground litter and root carbon input on soil organic carbon decomposition in different forest types. Here, we report on our detritus input and removal treatments conducted to investigate how changes in aboveground and belowground carbon inputs affect soil organic carbon content and various microbial carbon metabolic functions in different plantation types (oak vs. pine, broadleaf vs. coniferous). The results of our study showed that doubling aboveground litter significantly increased SOC content and labile carbon metabolism in the oak plantation but not the pine plantation. Root trenching and aboveground litter removal decreased SOC content and carbon metabolisms. The effect of root trenching on carbon metabolisms was weaker than litter removal in the oak plantation but not the pine plantation. Detritus input and removal treatments changed the diversity and function of labile carbon (starch, carbohydrates, and amines/amides) and the metabolic activity of soil microorganisms in oak plantation, but mainly influenced recalcitrant carbon (polymers) metabolism in the pine plantation. Detritus input and removal treatments influenced the composition of microbial carbon metabolic genes and functions mainly by modifying the soil environment and nutrient availability including moisture, pH, nitrate content, and available phosphorus content in the oak plantation, while it influenced carbon metabolism by altering soil moisture, and the ammonium, nitrate, and organic carbon content in the pine plantation. These findings indicate that different forest ecosystems could respond differently to different disturbances, and forest management should be adjusted accordingly.

Study on the evolution characteristic of intermediate during the pyrolysis of oil shale

The pyrolysis of oil shale is a complex process including a myriad of chemical reactions. A widely approved understanding suggests a two-step decomposition process for oil shale pyrolysis, considering bitumen as the intermediate product. In this study, intermediates derived from various pyrolysis conditions are comprehensively studied by FTIR, GC, GC-MS and NMR methods to understand the pyrolysis mechanism of oil shale and composition feature of intermediate. The pyrolysis of oil shale is a dynamic process, and the results show that the intermediate is continuously generated before 400 A degrees C, accompanying with the formation of final products from both intermediate and kerogen. The maximum yield of intermediates is presented at the fastest oil-producing temperature range (375 A degrees C in this study). Carbon chains in intermediate become short with the increase in temperature. Most components in pyrolysis intermediate are long straight aliphatic chains; thus, intermediate is much heavier than shale oil. Further reactions make intermediate convert into shale oil product. Aliphatic hydrocarbons occupied the biggest proportion over 86% at 375 A degrees C, mainly in the form of straight-chain alkanes. A few parts of aromatic fragments with small ring numbers will also transfer into intermediate. The heteroatom-containing compounds are mainly alcohols, ketones, amides and halohydrocarbons. High aromaticity in shale oil at high temperatures can be attributed to the condensation reaction of abundant aliphatic hydrocarbons in intermediate. During the conversion process from intermediate to final products, the generating capacity of oil is evidently higher than that of gas.

Selective catalytic hydrogenation of the N-acyl and uridyl double bonds in the tunicamycin family of protein N-glycosylation inhibitors

Tunicamycin is a Streptomyces-derived inhibitor of eukaryotic protein N-glycosylation and bacterial cell wall biosynthesis, and is a potent and general toxin by these biological mechanisms. The antibacterial activity is dependent in part upon a pi-pi stacking interaction between the tunicamycin uridyl group and a specific Phe residue within MraY, a tunicamycin-binding protein in bacteria. We have previously shown that reducing the tunicamycin uridyl group to 5,6-dihydrouridyl (DHU) significantly lowers its eukaryotic toxicity, potentially by disrupting the p-stacking with the active site Phe. The present report compares the catalytic hydrogenation of tunicamycin and uridine with various precious metal catalysts, and describe optimum conditions for the selective production of N-acyl reduced tunicamycin or for tunicamycins reduced in both the N-acyl and uridyl double bonds. At room temperature, Pd-based catalysts are selective for the N-acyl reduction, whereas Rh-based catalysts favor the double reduction to provide access to fully reduced tunicamycin. The reduced DHU is highly base-sensitive, leading to amide ring opening under mild alkaline conditions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2026-48-4, in my other articles.

Practical Synthesis of Phosphinic Amides/Phosphoramidates through Catalytic Oxidative Coupling of Amines and P(O)-H Compounds

Herein, we report a highly efficient ZnI2-triggered oxidative cross-coupling reaction of P(O)-H compounds and amines. This operationally simple protocol provides unprecedented generic access to phosphinic amides/phosphoramidate derivatives in good yields and short reaction time. Besides, the reaction proceeds under mild conditions, which avoids the use of hazardous reagents, and is applicable to scale-up syntheses as well as late-stage functionalization of drug molecules. The stereospecific coupling is also achieved from readily available optically enriched P(O)-H compounds.

pH-Responsive Charge-Conversion Progelator Peptides

A simple strategy for generating stimuli-responsive peptide-based hydrogels via charge-conversion of a self-assembling peptide (SAP) is described. These materials are formulated as soluble, polyanionic peptides, containing maleic acid, citraconic acid, or dimethylmaleic acid amide masking groups on each lysine residue, which do not form assemblies, but instead flow easily through high gauge needles and catheters. Acid-induced mask hydrolysis renews the zwitterionic nature of the peptides with concomitant and rapid self-assembly via beta-sheet formation into rehealable hydrogels. The use of different masks enables one to tune pH responsiveness and assembly kinetics. In anticipation of their potential for in vivo hydrogel delivery and use, progelators exhibit hemocompatibility in whole human blood, and their peptide components are shown to be noncytotoxic. Finally, demonstration of stimuli-induced self-assembly for dye sequestration suggests a simple, non-covalent strategy for small molecule encapsulation in a degradable scaffold. In summary, this simple, scalable masking strategy allows for preparation of responsive, dynamic self-assembling biomaterials. This work sets the stage for implementing biodegradable therapeutic hydrogels that assemble in response to physiological, disease-relevant states of acidosis.

Oxidative Phosphorylation of N-Aryl Glycine Amides via sp(3) C-H Functionalization

An efficient phosphorylation of various glycine amides has been developed for radical cation salt-induced C-H functionalization, producing a series of alpha-aminophosphonates in high yields.

Methylofuran is a prosthetic group of the formyltransferase/hydrolase complex and shuttles one-carbon units between two active sites

Methylotrophy, the ability of microorganisms to grow on reduced one-carbon substrates such as methane or methanol, is a feature of various bacterial species. The prevailing oxidation pathway depends on tetrahydromethanopterin (H4MPT) and methylofuran (MYFR), an analog of methanofuran from methanogenic archaea. Formyltransferase/hydrolase complex (Fhc) generates formate from formyl-H4MPT in two consecutive reactions where MYFR acts as a carrier of one-carbon units. Recently, we chemically characterized MYFR from the model methylotroph Methylorubrum extorquens and identified an unusually long polyglutamate side chain of up to 24 glutamates. Here, we report on the crystal structure of Fhc to investigate the function of the polyglutamate side chain in MYFR and the relatedness of the enzyme complex with the orthologous enzymes in archaea. We identified MYFR as a prosthetic group that is tightly, but noncovalently, bound to Fhc. Surprisingly, the structure of Fhc together with MYFR revealed that the polyglutamate side chain of MYFR is branched and contains glutamates with amide bonds at both their alpha- and gamma-carboxyl groups. This negatively charged and branched polyglutamate side chain interacts with a cluster of conserved positively charged residues of Fhc, allowing for strong interactions. The MYFR binding site is located equidistantly from the active site of the formyltransferase (FhcD) and metallo-hydrolase (FhcA). The polyglutamate serves therefore an additional function as a swinging linker to shuttle the one-carbon carrying amine between the two active sites, thereby likely increasing overall catalysis while decreasing the need for high intracellular MYFR concentrations.

MOLECULAR MODELS IN CHEMISTRY EDUCATION AT UNIVERSITY AND UPPER SECONDARY SCHOOL – STRUCTURE OF AMIDES

Molecular models derived from results of quantum-chemical calculations present an important category of didactic instruments in chemistry education in upper secondary school and, particularly, at university. These models can be used especially as tools for supporting the students’ understanding by visual learning, which can adequately address complexity of many chemical topics, incorporate appropriate didactic principles, as well as utilize the benefits brought up by the actual information technology. The proposed molecular models are non-trivial examples of didactic application of computational chemistry techniques in illustration of electron interactions in amidic group, namely the interaction of the free electron pair on the nitrogen atom with the carbonyl group and also the interaction of atoms in the amide group with other surrounding atoms in the molecule. By these molecular models it is possible to explain acid-base properties of amides applying knowledge of electron density distribution in the molecules and the resulting electrostatic potential. Presentation of the structure and properties of the amides within education is important also for the reason that amidic functions are involved in many important natural substances (e.g. proteins, peptides, nucleic acids or alkaloids), synthetic macromolecular substances (e.g. Silon) or pharmaceutical preparations (e.g. paracetamol). Molecular models then serve to support better understanding of the structure of these substances and, in relation to it, their properties.
