The degradation behavior of eight benzodiazepines (BZPs): alprazolam, etizolam, diazepam, triazolam, nitrazepam (NZP), flunitrazepam (FNZ), bromazepam, and lorazepam, in artificial gastric juice was monitored by a LC/photodiode array detector (PDA) to estimate their pharmacokinetics in the stomach. For drugs that
We have developed the [5-(4-nitrophenyl)-2-furyl]acrylic acid substituted benzophenone 4g as a novel lead for anti-malarial agents. Here, we demonstrated that the acyl residue at the 2-amino group of the benzophenone core structure has to be a phenylacetic acid substructure substituted

The FT-IR and Raman spectra of 2-amino-5-nitrobenzophenone (ANBP) molecule have been recorded using Brucker IFS 66 V spectrometer in the range of 4000-100 cm(-1). The molecular geometry and vibrational frequencies in the ground state are calculated using the Hartree-Fock (HF)

The role of single crystal diffraction in the quantitative determination of polymorphism is demonstrated by the examination of three compounds. Two polymorphs were found for each of the compounds bis(2-nitrophenyl) trisulphide (1), 2-amino-5-nitrobenzophenone (2) and bis(2-nitrophenyl) sulphide (3). Only in

A method for the direct quantitative densitometry of nitrazepam and its main metabolites (7-aminonitrazepam, 7-acetamidonitrazepam and 2-amino-5-nitrobenzophenone) in urine was developed. The unchanged drug and its metabolites were extracted with benzene-dichloromethane (4:1), subjected to thin-layer chromatography, and determined by direct
