Journal ArticleDOI
Development of a simple, rapid, and robust liquid chromatographic method for the simultaneous determination of sulfalene, sulfadoxine, and pyrimethamine in tablets.
TL;DR: The RP-HPLC method allows a quick quantitative determination of sulfadoxine and sulfalene and the separation of the respective impurities within a total runtime of approximately 15min and was validated with respect to specificity, linearity, precision, accuracy, limits of detection and quantification, robustness, and stability of the standard and sample solutions.
Journal ArticleDOI
Cer(IV)‐Oxidationen von β‐Aminoketonen. 3. Mitt.: Ein Syntheseweg zu 4‐spirosubstituierten 1,2,3,4‐Tetrahydroisochinolinen
TL;DR: In this article, a pathway to 4-Spiro is described for synthesizing 1,2,3,4,4-Tetrahydroisoquinolines.
Journal ArticleDOI

TL;DR: The presented results justify the use of royal fern extracts as an anti-cancer remedy in history and imply a further analysis of ingredients.
Journal ArticleDOI
Comparison of the separation of aziridine isomers applying heptakis(2,3-di-O-methyl-6-sulfato)β-CD and heptakis (2,3-di-O-acetyl-6-sulfato)β-CD in aqueous and nonaqueous systems
TL;DR: Robust baseline separations were obtained using heptakis(2,3‐di‐O‐acetyl‐6‐sulfato)β‐CD (HDAS) in acidic methanol and sulfated β‐CD in acidic phosphate buffer, and the method will be used as a screening method for further isomeric mixtures of aziridines.
Journal ArticleDOI
Stereochemistry and opioid receptor affinity of 2,4‐dipyridine‐3,7‐diazabicyclo[3.3.1]nonanones ‐ influence of the substituent in position N7
TL;DR: The stereochemistry the 2,4-di-arene substituted 3,7-diazabicyclo[3.3.1]nonan-9-one 1,5-dicarboxylate skeleton was found to be regulated by the kind of substituents attached to the arene rings as well as to the nitrogens N3 and N7.
