Proton nuclear magnetic resonance (1H NMR) spectroscopy is a noninvasive technique that can provide information on a wide range of metabolites. Marked abnormalities of 1H NMR brain spectra have been reported in patients with neurological disorders, but their neurochemical implications may be difficult to appreciate because NMR data are obtained from heterogeneous tissue regions composed of seve...

1-{β-[3-(4-Methoxy-phenyl)propoxy]-4-methoxyphenethyl}-1H-imidazole hydrochloride 7, or SKF-96365, was synthesized in four steps with an overall yield of 9%. The structure of 7 was confirmed by 1H-, 13C-NMR, HRMS, and elemental analysis. The intermediates 3 and 4 were also isolated and characterized by 1H-, 13C-NMR, and HRMS.

Methyl 9-(1-methyl-1H-indol-3-yl)-9-oxononanoate was synthesized using Friedel–Crafts acylation between N-methyl indole and methyl 9-chloro-9-oxononanoate. The structure of the newly compound elucidated 1H-NMR, 13C-NMR, NOESY-1D, ESI-MS, FT-IR, UV-Vis spectroscopy.

The title compound, 1-phenyl-3,3-di(1H-pyrazol-1-yl)propan-1-one, was synthesized in a 52% yield for the first time by one-step reaction between 1H-pyrazole and 1-phenylprop-2-yn-1-one (their ratio being 2:1) solid Al2O3 at room temperature. product characterized 1H-NMR, 13C-NMR, IR spectroscopy, X-Ray diffraction elemental analysis.

A study electrical conductivity a survey biological act...

Abstract Background Mucoadhesive polymers are applicable for improving the delivery of drug by prolonging residence time and contact dosage form with mucous membrane. Mucoadhesion may be defined as a process where polymer substance gets adhered either to biological substrate or synthetic natural macromolecule, mucus The can studied determine whether they possess some mucoadhesive properties sev...

In this study, a chemical dissolution treatment was used to recover rubber and carbon black (CB) from truck tire scrap, with gas oil acting as the solvent 4-Hydroxy-TEMPO catalyst for reactions. Montmorillonite clay separate solution CB other non-dissolved additives. The recovered were characterized together original scrap sample by XRD, SEM, BET thermal analysis, well FTIR 1H NMR spectral anal...

A diverse series of imine linked 1,2,3-triazole hybrids has been synthesized via Cu(I)-promoted click reaction, with an aim to develop some new antimicrobial molecules. The structural characterization the triazole was accomplished using various spectral techniques like 1H NMR, 13C FTIR and HRMS. Among hybrids, 7d exhibited highest efficacy against R. oryzae S. aureus MIC 0.0123 µmol/mL 0.0061 µ...
