Curcumin Isolation, Synthesis and Characterization of Curcumin Isoxazole Derivative Compound

Curcumin, one of the curcuminoid constituents which derived from Curcuma longa, has been extensively used as a pharmacological agent. This study was started with extraction of the curcuminoid from Curcuma longa where extraction was carried out with two different solvents (dichloromethane and ethanol), followed by isolation of curcumin from the other two components of curcuminoid. The pure curcumin was converted to its isoxazole derivative with the addition of NH2OH center dot HCl. The reaction product was characterized using mass spectrometry, UV/Vis and FTIR spectrophotometry. Optimization of the extraction and synthesis shows that for the extraction ethanol was a better solvent than dichloromethane with 12.67 % yield. Temperature and optimization time for synthesis of curcumin isoxazole were 70 degrees C and 8 hours, respectively.

The readily available 3-methylisoxazol-5-amine (1) has been used as a key intermediate for the synthesis of isoxazolo[5,4-b]pyridine, pyrrolo[3,2-d]isoxazole, isoxazolo[5,4-b]azepine-4,7-dione and isoxazole derivatives via its reactions with some chemical reagents. Sixteen compounds were designed to study their cytotoxic properties against three human cell lines: colorectal carcinoma (HCT-116), prostate cancer (PC3) and normal lung fibroblast (WI-38), using the MTT colorimetric assay. 5-Fluorouracil, a well-known anticancer drug, was used for comparison. Among the tested candidates, pyrrolo[3,2-d]isoxazole 5 and isoxazole derivatives 11-14 showed the highest activity against the tested cancer cell lines with good selectivity by their lower toxicity against normal cells.

Vibrational assignment of isoxazole aided by rovibrational data and density functional theory

IR and Raman spectra of isoxazole and D(3)-isoxazole are reassigned with the aid of density functional theory calculations at the B3LYP/6-311+G(d,p) level. Harmonic wavenumber values of all non-CH stretch modes give an r.m.s. deviation from experimental values of 3 cm(-1) when they are uniformly scaled by 0.9818. Anharmonic values obtained using a second-order perturbative approach show an r.m.s. deviation of 7.6 cm(-1). Results of equal quality are obtained for D(3)-isoxazole. Predicted Raman and IR band strengths match experimental spectra very closely. Detailed re-examination of rovibrational constants and inertial defect data from high resolution IR spectra, in comparison with values from the anharmonic frequency calculation, provides confirmation of the vibrational assignments. ‘Dark state’ fundamentals nu(12) (900.2 cm(-1)) and nu(15) (866 cm(-1)) are detected through the perturbations they cause in nearby bands.

Isoxazole derivatives of silatrane: synthesis, characterization, in silico ADME profile, prediction of potential pharmacological activity and evaluation of antimicrobial action

A new family of mono- (3a-h) and bis- (4a-g) isoxazole-bridged silatranes has been synthesized by the reaction of 3-aminopropylsilatrane (1) and 3-substituted 5-chloro-methylisoxazoles (2a-h). The structure of the isoxazole-silatrane hybrids is characterized by elemental analysis, FT-IR, UV, NMR (H-1,C-13,Si-29 and(15)N) spectroscopy, high-resolution mass spectrometry, and X-ray diffraction analysis. Thein silicoADME (absorption, distribution, metabolism, excretion) assessment reveals that properties of mono-adducts (3a-h) are similar to those of drugs obeyed to the Lipinski’s rule. The calculated screening of potential pharmacological activity profiles (in silicoPASS program) of isoxazole-silatranes shows that all synthesized compounds (both mono- and bis-substituted) may have high antitumor action, unlike starting isoxazoles. The preliminary screening of the synthesized silatranes for antimicrobial activity againstEnterococcus durans,Bacillus subtilis,Escherichia coli,andPseudomonas aeruginosaindicates that all test samples are active only against gram-positive microorganisms. Silatrane3fdisplays minimal inhibitory concentration (MIC 12.5 and 6.2 mu g ml(-1)) againstE. duransandB. subtilisas compared with standard drug gentamicin (MIC 25 and 50 mu g ml(-1)).

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 446292-10-0. Product Details of 446292-10-0.

The preparation of an isoxazole derivative of 4-hydroxycoumarin

A method for preparation of an isoxazole derivative of 4-hydroxycoumarin, 3-phenyl-5-(4-hydroxy-3-coumarinyl)-isoxazole has been described. The reaction sequence includes addition of bromine to 3-cinnamoyl-4-hydroxycoumarin, and the subsequent treatment of the obtained dibromo derivative with 2 equivalents of sodium azide. Due to steric reasons, the azido group is introduced in the beta-position with respect to the side chain carbonyl group, so that an isoxazole ring can be formed. The total yield of the reaction was 58%.

Metal-free 1,3-dipolar cycloaddition approach towards the regioselective synthesis of beta-carboline and isoxazole based molecular hybrids

Nature has nourished beta-carboline and isoxazole derivatives as privileged scaffolds and consequently they are ubiquitously found in alkaloids isolated from various sources. Moreover, several drug molecules based on them have been released in the market. Considering their immense impact, novel beta-carboline-isoxazole- based molecular hybrids have been designed and a 1,3-dipolar cycloaddition strategy was devised to prepare the desired prototypes. A library of compounds with a wide range of diversity have been developed by employing beta-carboline-containing dipolarophiles as well as dipoles. The current method represents a simple, efficient and easy-to-execute protocol towards the regioselective synthesis of beta-carboline-isoxazole conjugates.
