Synthesis and Fungicidal Activity of Novel Pyrazole-4-carbox-amide Compounds Containing Tertiary Alcohol Moiety

A series of novel pyrazole-4-carboxamide compounds were designed and synthesized through introducing a tertiary alcohol moiety into the C-3 position of the pyrazole ring based on the chracteristics of pyrazole-4-carboxamide fungicides and natural products with a tertiary alcohol moiety. Their structures were characterized by H-1 NMR, C-13 NMR, HR-ESI-MS data and X-ray diffraction. The preliminary bioassay results indicated that some of these compounds exhibit certain fungicidal activities against tested phytopathogens at the concentration of 100 mu g/mL. N-(2-Fluorophenyl)-3-(1-hydroxycyclohexyl)-1,5-dimethyl-1H-pyrazole-4-carboxamide (B-1) and N-(thiazol-2-yl)-3-(1-hydroxycyclohexyl)-1,5-dimethyl-1H-pyrazole-4-carboxamide (B-10) have EC50 values of 76.3 and 71.9 mu g/mL against Pythium aphanidermatum. B-10 has an EC50 value of 85.4 mu g/mL against Phytophthora capsici, respectively.

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.

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.

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.

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.

Effects of High Hydrostatic Pressure assisted degreasing on the technological properties of insect powders obtained from Acheta domesticus & Tenebrio molitor

In this study, two edible insect species; Acheta domesticus (house cricket) and Tenebrio molitor (yellow mealworm) were defatted using different extraction methods and characterized afterwards. The main goal of the study was to see the effect of High Hydrostatic Pressure (HHP) extraction at different temperatures on the functional properties of the insect powders. Protein content, solubility, water and oil binding capacity; total phenolic content and antioxidant activity were all effected from the extraction method. Results showed that, temperature increase from 30 to 40 degrees C caused a decrease in the protein solubility of both powders. NMR relaxometry was used to interpret the gelation behavior and FTIR spectroscopy showed absorbance peaks mainly in amide I, amide II and amide III regions for both species. Results confirmed that HHP can be used for defatting purposes and could improve the functional properties of the powders to be used as a food additive in formulations.
