The European Pharmacopoeia (Ph. Eur.) and other official compendia give only a general description of the stationary phase in the description of a liquid chromatographic method. Therefore the selection of a column giving suitable selectivity presents

The current method prescribed in official monographs for the purity control of vancomycin is inappropriate in that several components are not separated from each other and other components are coeluted with the main component vancomycin B. The method

The hydroxide-catalyzed hydrolysis of 3,6-diacetylmorphine (heroin) was shown to take place predominantly via its positively charged form. N-Methylated quaternary derivatives of heroin bearing a permanent positive charge were synthesized, and thus, h

Liquid chromatography (LC) methods compatible with mass spectrometry (MS) that are suitable for impurity profiling of vancomycin mixtures have not been described in the literature. The mobile phases of the existing methods contain non-volatile additi

Rotamers of N-acetyl-L-cysteine (NAC, the most popular mucolytic drug) are characterized in terms of populations, site- and conformer-specific acid-base properties, reducing strength, and molecular pharmacology. A new, general relationship between th

Ester-type compounds are important drugs as directly binding active principles, but also, as prodrugs that provide the acting agent after hydrolytic decomposition. The profound characterisation of the kinetics of ester hydrolysis is therefore equally
