New Substituted 5-Benzylideno-2-Adamantylthiazol[3,2-b][1,2,4]Triazol-6(5H)ones as Possible Anti-Inflammatory Agents

Background: Inflammation is a complex response to noxious stimuli promoted by the release of chemical mediators from the damaged cells. Metabolic products of arachidonic acid, produced by the action of cyclooxygenase and lipoxygenase, play important roles in this process. Several non-steroidal anti-inflammatory drugs act as cyclooxygenase inhibitors. However, almost all of them have undesired side effects. Methods: Prediction of the anti-inflammatory action of the compounds was performed using PASS Program. The anti-inflammatory activity was evaluated by the carrageenan paw edema test. COX and LOX inhibitory actions were tested using ovine COX-1, human recombinant COX-2 and soybean LOX-1, respectively. Docking analysis was performed using Autodock. Results: All designed derivatives had good prediction results according to PASS and were synthesized and experimentally evaluated. The compounds exhibited in vivo anti-inflammatory action with eleven being equal or better than indomethacin. Although, some of them had no or low inhibitory effect on COX-1/2 or LOX, certain compounds exhibited COX-1 inhibition much higher than naproxen and COX-2 inhibition, well explained by Docking analysis. Conclusions: A number of compounds with good anti-inflammatory action were obtained. Although, some exhibited remarkable COX inhibitory action this activity did not follow the anti-inflammatory results, indicating the implication of other mechanisms.

The Three-Component Synthesis of 4-Sulfonyl-1,2,3-triazoles via a Sequential Aerobic Copper-Catalyzed Sulfonylation and Dimroth Cyclization

4-Sulfonyl-1,2,3-triazole scaffolds possess promising bioactivities and applications as anion binders. However, these structures remain relatively unexplored and efficient synthetic procedures for their synthesis remain desirable. A practical room-temperature, aerobic copper-catalyzed three-component reaction of aromatic ketones, sodium sulfinates, and azides is reported. This procedure allows for facile access to 4-sulfonyl-1,5-disubstituted-1,2,3-triazoles in yields ranging from 34 to 89%. The reaction proceeds via a sequential aerobic copper(II)chloride-catalyzed oxidative sulfonylation and the Dimroth azide-enolate cycloaddition.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 288-88-0. Recommanded Product: 1H-1,2,4-Triazole.

Paclobutrazol as a plant growth regulator

Plant growth regulators are chemical substances which govern all the factors of development and growth within plants. The application of plant growth regulators to crops modifies hormonal balance and growth leading to increased yield, enhanced crop tolerance against abiotic stress and improved physiological trait of crops. Paclobutrazol (PBZ) [(2RS, 3RS)-1-(4-chlorophenyl)- 4, 4-dimethyl-2-(1H-1, 2, 4-trizol-1-yl)-pentan-3-ol], is one of the members of triazole family having growth regulating property. The growth regulating properties of PBZ are mediated by changes in the levels of important plant hormones including the gibberellins (GAs), abscisic acid (ABA) and cytokinins (CK). PBZ affects the isoprenoid pathway, and alters the levels of plant hormones by inhibiting gibberellin synthesis and increasing cytokinins level and consequent reduction in stem elongation. When gibberellins synthesis is inhibited, more precursors in the terpenoid pathway accumulate and that resulted in the production of abscisic acid. PBZ is more effective when applied to the growing media and application on the growing medium would give longer absorption time and more absorption of active ingredient than foliar spray. The application of PBZ to crops is important in reducing plant height to prevent lodging and in increasing number and weight of fruits per tree, in improving the fruit quality in terms of increases in carbohydrates, TSS, TSS/TA and decreases acidity. It further reduces evapo-transpiration and decreases plant moisture stress by enhancing the relative water content of leaf area and develops resistance in the plants against biotic and abiotic stresses. In addition, it acts as highly active systemic fungicide and used against several economically important fungal diseases. In this review, the current knowledge and possible applications of PBZ, which can be used to improve the growth, yield and quality of crops, have been reviewed and discussed. The role of PBZ to mitigate the harmful effects of environmental stresses in crops is also examined. Moreover, various biochemical and physiological processes leading to improved crop production under the effect of PBZ are discoursed in detail.

Utility of solid-phase extraction coupled with spectrophotometry for a novel green nano determination of copper(II) using 4-((furan-2-ylmethylene) amino)-5-methyl-4H-1,2,4-triazole-3-thiol

A highly sensitive, selective and accurate method has been developed to determine ultra trace amounts of copper(II) by solid-phase extraction (SPE). The following parameters such as pH, concentration of the reagent, Triton X-100, reversed-phase Amberlite IR-120, equilibrating temperature and centrifuging time were evaluated to enhance the sensitivity and extraction efficiency of the proposed method. The method has been based on copper(II) and 4-((furan-2-ylmethylene) amino)-5-methyl-4 H-1,2,4-triazole-3-thiol (FAMT) reaction, followed by solid-phase extraction (SPE) of Cu(II)-FAMT with a reversed-phase Amberlite IR-120. This was performed by using borate buffer solution of pH 7.6 in the presence of Triton X-100 medium. FAMT reacts with copper(II) to form a deep green complex with molar ratio of (2: 1) (FAMT: copper). An enrichment and improvement factor of 200 and 540, respectively, were obtained by elution of the complex from the resin with a minimal amount of dimethylsulfoxide (0.5 mL). The molar absorptivity of the complex was 6.49 x 10(6) L mol(-1) cm(-1) at 499 nm. Beer’s law was obeyed in the range 5.0-190 ng mL(-1) of the measured solution. After optimising the instrumental and experimental parameters, the maximum values for quantification and detections limits of 100 mL sample system were 5.40 and 1.64 ng mL(-1). The suggested method has been successfully applied for determination of copper ions in various environmental (water, vegetables, food, and biological) samples.

Novel triazole derivatives as ecological corrosion inhibitors for mild steel in 1.0 M HCl: experimental & theoretical approach

The present paper illustrates the investigation of two novel ecological triazole derivative corrosion inhibitors, namely ethyl 2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetate [Tria-CO2Et], and 2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetohydrazide [Tria-CONHNH2]. The studied inhibitors were investigated against the corrosion of mild steel in 1.0 M HCl solution using different electrochemical techniques. Potentiodynamic polarization experiments indicated that the [Tria-CO2Et], and the [Tria-CONHNH2] acted as mixed type inhibitors. Electrochemical impedance spectroscopy measurements revealed that both inhibitors presented a high inhibition performance, achieving an inhibition efficiency of 95.3% for [Tria-CO2Et] and 95.0% for [Tria-CONHNH2] at a concentration of 1.0 x 10(-3) M. Based on the Langmuir isotherm model and the activation parameters, these triazole derivatives were adsorbed onto a steel surface by physical and chemical bonds. Density functional theory based on B3LYp6-311G(d,p) was also carried out to correlate the inhibition efficiencies obtained experimentally with the theoretical descriptors of the studied molecular structures.

A porous Co-MOF for CO2 conversion and protective activity on infectious fever by reducing bacterial inflammatory response

By applying a mixed-ligand approach based on an amino functionalized ligand 1-aminobenzene-3,4,5-tricarboxylic acid (H(3)abta), a novel metal-organic framework (MOF) containing Co(II) ion {[Co-2.5(abta)(trz)(2) (H2O)]center dot 3H(2)O}(n) (1, Htrz = 1H-1,2,4-triazole) were produced via Co(NO3)(2)center dot 6H(2)O reacting with H(3)abta with the existence of Htrz as the co-ligand. The prepared catalyst 1a (activated 1) is abundant in the amino groups and open metal sites (OMSs), which is helpful to obtain high CO2 capacity of adsorption around room temperature and effectively convert CO2 to pentacyclic carbamate with the help of Bu4NBr as the cocatalyst. For the treatment of infectious fever, the colony-forming unit (CFU) was performed and the E. coli number in the mice was counted. Next, the inflammatory cytokines level in the infected mice was measured after the compound treatment. [GRAPHICS] .

Synthesis and properties of novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts as attractive energetic materials

The incorporation of both fuel and oxidizer properties into a single molecule to effectively improve the oxygen balance of energetic compounds has become one of the most acceptable strategies for the design of modern high-energy-density materials (HEDMs). To identify more powerful and less sensitive HEDMs with favorable oxygen balance, novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts were prepared via the quaternization of 3,4-diamino-triazole with 4,4′-bis(nitramino)azofurazan and 4,4′-bis(nitramino)azoxyfurazan, and then fully characterized. These compounds exhibited favorable thermal stabilities with decomposition temperatures up to 216 degrees C, high densities over 1.82 g.cm(-3) as well as acceptable sensitivities. In addition, the two-dimensional fingerprint spectra based on Hirshfeld surface analysis were adopted to illustrate structure-property relationships. Based on the combination of experimentally determined densities and heats of formation calculated with Gaussian 03, the energetic properties were determined using the EXPLO5 v6.02 program. The newly synthesized ionic salts displayed excellent detonation properties (V-d, 9115-9220 m.s(-1); P, 33.9-35.4 GPa), comparable to those of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), thus highlighting their potential in energetic material applications.

A real-time and highly sensitive fiber optic biosensor based on the carbon quantum dots for nitric oxide detection

Nitric oxide (NO) is a signal molecule with a wide range of functions and unique properties in organisms. A novel fluorescent probe composed of carbon quantum dots (CQDs) with o-phenylenediamine groups was prepared by the microwave method to detect NO selectively. The mechanism of the reaction between CQDs and NO was established by a series of characterization methods, such as fluorescence spectrophotometer, UV-vis absorption spectrophotometer and transmission electron microscope. The result showed that the o-phenylenediamine groups on the surface of the CQDs can react with NO to form an electron-free triazole structure, leading to the decrease of fluorescence of the CQDs. Furthermore, a new optical fiber sensing system based on the CQDs was constructed to detect NO with a low detection limit of 9.12 nM at laser power of 280 mW. In addition, the NO optic fiber biosensor also was used to detect NO concentration in real human serum samples.
