One-pot three-component azide-alkyne cycloaddition: Synthesis of new pyrazole, 1,2,3-triazole, and oxadiazole tethered and their anti-inflammatory, quantitative structure-activity relationship, and docking studies

A simple and efficient one-pot three-component azide-alkyne cycloaddition of 5-chloro-1-phenyl-pyrazole-4-carbaldehyde with 2-(prop-2-yn-1-ylthio)-5-(substituted phenoxy)methyl-1,3,4-oxadiazole and sodium azide is reported. The newly synthesized compounds were characterized by spectral and analytical data. They were screened for in vitro anti-inflammatory activity by bovine serum albumin denaturation assay. All the tested compounds showed moderate anti-inflammatory activity, whereas three compounds (4d, 4i, and 4k) showed excellent activity comparable with that of the standard drug diclofenac sodium. The quantitative structure-activity relationship (QSAR) study was carried out for anti-inflammatory activities of the synthesized compounds and developed a QSAR model. Inspired by their in vitro anti-inflammatory activities, they were docked to the active site of COX-2 to know the anti-inflammatory potency in silico.

Copper-Catalyzed Aerobic Cyclization of ss,gamma-Unsaturated Hydrazones with Concomitant C=C Bond Cleavage

A Cu-catalyzed aerobic oxidative cyclization of ss,gamma-unsaturated hydrazones for the preparation of pyrazole derivatives has been developed. The hydrazonyl radical promoted the cyclization, along with a concomitant C=C bond cleavage of ss,gamma-unsaturated hydrazones. This process has been verified via several control experiments, including a radical-trapping study, an 18O-labeling method, and the identification of the possible byproducts. The advantages of this reaction include operational simplicity, a broad reaction scope, and a mild selective reaction process.

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 4233-33-4. Formula: C8H5N3O2.

Synthesis and photophysical properties of new pyrazolines with triphenyl and ester derivatives

New (4S*,5S*)-Methyl 3-(2,3-dimethoxyphenyl)-5-(3,4-dimethoxyphenyl)-1-phenyl-4,5-dihydro-1H-pyrazole-4-carboxylate (4) and its isomer 5 were synthesized from 1,3-dipolar cycloaddition reaction of a hydrazonyl chloride with a cinnamic acid derivative and solvent effects on absorption and fluorescence properties of the novel synthesized pyrazoline derivatives (isomers 4 and 5) were studied by UV-Vis. absorption and steady-state fluorescence spectroscopy techniques. The absorption and fluorescence spectra for both isomers showed that solvent structure and polarity have effect on photophsical properties of the isomer molecules. Isomers 4 and 5 exhibited positive solvatochromism behavior when the polarity of the solvent was increased from p-Xylene to MeOH. Furthermore, isomers 4 and 5 showed very high quantum yields in the solvents except for polar solvents and bromobenzene. Solute-solvent interactions were analyzed by using the solvent polarity parameter (E-T(30)) approach, Lippert-Mataga equation, Kamlet-Taft and Catalan multiple linear regression analysis. These results revealed that the most contributing factor of solute-solvents interactions for the isomer 4 was the solvent acidity whereas the most contributing factors for isomer 5 was the solvent acidity as well as the solvent polarity.
