Ethylenamine derivatives. After growing crystals of N,N′-bis(9-phenyl-9-thioxanthenyl)ethylenediamine from various alkyl halide solvents, we discovered that this host is highly proficient for the enclathration of these guest types. 2-Benzylaminopyrridine, in turn, can be easily synthesized by reduction of a Schiff base, synthesized by condensation of 2-aminopyrridine with benzaldehyde [9–11].

All Publications/Website. A sensitive method for following this interaction involves the use of an analog cis-[3H]dichloro(ethylenediamine)platinum(II) (cis-[3H]DEP). J. ATP-utilising systems vary enormously in their specificity; so what acts as a good analogue in one case may be very poor in another. The aim of this study was to develop and validate a bioanalytical method for quantification of (S,S)-O,O-diethyl-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoate dihydrochlorides (DE-EDCP) and its metabolite, substituted propanoic acid (EDCP), in mouse serum by ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).
