Abstract:
The redox potential (ΔE1/2), electron affinity (EA), ionization potential (IP), coulomb repulsion integral (J12), and electronic transition energy (ECT) of several oxazolone derivatives in DMF were computed. A linear correlation was shown to exist between ΔE1/2 and ECT• The polarographic reduction was investigated in ethanolic-Theil buffer solutions. At pH ≤ 7.2, two waves were obtained representing the uptake of 2- and 4-electron steps respectively. In alkaline media, a third wave appeared seemingly a result of the hydrolysis of oxazolones. The rate of hydrolysis was determined and the electr

Abstract:
Rifaximin is known as an oral antibiotic that can be used in a wide range of digestive diseases, but not only. Chemically, rifaximin is a yellow solid powder that can be relatively easily dissolved in methanol and which, because of its color, can be analyzed spectrophotometric. To be able to use such a simple method in the quantitative analysis of rifaximin, the most important spectrophotometric characteristics are required. In this study, these spectrophotometric characteristics (maximum wavelength (&lambda;<sub>max</sub>, nm), spectral band width (&Delta;&lambda;<sub>1/2</sub>, nm), molar ab

Abstract:
Titrimetric and spectrophotometric methods are described for the determination of oxcarbazepine (OXC) in bulk drug and in tablets. The methods use N-bromosuccinimide (NBS) and bromopyrogallol red (BPR) as reagents. In titrimetry (method A), an acidified solution of OXC is titrated directly with NBS using methyl orange as indicator. Spectrophotometry (method B) involves the addition of known excess of NBS to an acidified solution of OXC followed by the determination of the unreacted NBS by reacting with BPR and measuring the absorbance of the unreacted dye at 460 nm.

A consequence of this increased exposure is the 88 to 875-fold amplification of the peroxidase activity in 1-65H over horse heart cytochrome c_.
