A series of novel 3, 4-methylenedioxybenzene scaffold incorporated 1,3,5-trisubstituted-2-pyrazoline derivatives was synthesised as potent antitubercular agents via chalcone intermediates by reaction with hydrazines. The structures of the compounds were confirmed by IR, 1HNMR, 13CNMR and mass spectral data. The novel pyrazolines were screened for in vitro antitubercular activity by almar blue d...

Metabonomics and other "omics" fields are essential science in analytical chemistry. Modern analytical instruments such as proton nuclear magnetic resonance ((1)H NMR) can be provided the great quantity of analytical information. In order to assign unknown samples, chemometrics methods recognition build classification model based on experimental data. Firstly some current strategies for regardi...

Schiff's bases are one of the important classes ligands, which obtained by condensation amine and aromatic aldehyde. The metal complexes widely considered because they show excellent biological activities. Such as antimicrobial, antitumor, antibacterial, anti-fungal properties. present studies deal with synthesis characterization base transition synthesized from general formula (ML) M=Co(II) Cu...

Dyes present in the effluent of textile industries are recalcitrant molecules difficult to be degraded biologically. In this study we used Pseudomonas fluorescens to degrade Direct Orange 102 dye. Pseudomonas fluorescens NCIM 2100 was obtained from National Chemical Laboratory, Pune, India, that was adapted to grow on Direct Orange 102. The dye was subjected to degradation by the bacterium and ...

the reaction between trimethylamine with propargyl bromide was studied and the structure of triethyl propargyl ammonium bromide was illustrated by 1hnmr, ir, and mass spectra.

Equilibrium constants of Cadmium Oxide (CdO) nanoparticles complexes in human cancer cells with DNA/RNA ligands have been studied with biospectroscopic methods such as 1HNMR, 13CNMR, 31PNMR, Attenuated Total Reflectance Fourier Transform Infrared (ATR–FTIR) and FT–Raman spectroscopies in cosolvent systems at 10, 20, 30°C ± 0.5 and 1 mol.dm–3 ionic strength, was maintained using Sodium Chloride ...

A series of Pyrano[2,3-d]Pyrimidine derivatives were synthesis using Knoevenagel and Michael addition reaction. Investigation of antimicrobial properties were done against gram positive bacteria Staphylococcus(NCTC-7447),Bacillus cereus(ATCC-14579) and gram negative bacteria Serratia maresens(IMRU-70), Proteus merabitis (NTCC-289) using Ampicillin as standard drugs. These synthesized compounds ...

Synthesis of Some Benzimidazole derivatives 4'-(5, 6-substitued-2-trifluoromethylbenzoimidazol-1-ylmethyl)-biphenyl-2-carboxylic acid were synthesized by condensation of various steps with different o-Phenylenediamine was condensed with in propylene glycol was added trifluoroacetic acid in the presence of BF3•OEt2 as catalysis. Elemental analysis, IR, 1HNMR and mass spectral data confirmed the ...
