Chem.,2020,11, of carbon-substituted piperazine pharmacophores 745 and oxidative related heterocycles Plato A. Magriotis † The important requirement for approval of a new drug, in case it happens to be chiral, is that both enantiomers of the drug should be studied in detail, which has led synthetic organic and medicinal chemists to focus their attention on the development of new methods for asymmetric synthesis especially of relevant saturated N-heterocycles. On the other hand, the piperazine ring, besides defining a major class of saturated N-heterocycles, has been classified as a privileged structure in medicinal chemistry, since it is more than frequently found in biologically active compounds including several marketed blockbuster drugs such as Glivec (imatinib) and Viagra (sildenafil). Indeed, 13 of the 200 best-selling small molecule drugs in 2012 contained a piperazine ring. Nevertheless, analysis of the piperazine substitution pattern reveals a lack Creative Commons Attribution 3.0 Unported Licence. of structural diversity, with almost every single drug in this category (83%) containing a substituent at both Received 16th February 2020, the N1- and N4-positions compared to a few drugs having a substituent at any other position (C2, C3, C5, Accepted 27th April 2020 and C6).

Mass Spectral, Infrared and Chromatographic Studies on Designer Drugs of the Piperazine Class by Karim M. Hafiz Abdel-Hay a Diss
Mass Spectral, Infrared and Chromatographic Studies on Designer Drugs of the Piperazine Class by Karim M. Hafiz Abdel-Hay A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the degree of Doctor of Philosophy Auburn, Alabama May 7, 2012 Approved by C. Randall Clark, Chair, Professor of Pharmacal Sciences Jack DeRuiter, Professor of Pharmacal Sciences Forrest Smith, Associate Professor of Pharmacal Sciences Angela Calderon, Assistant Professor of Pharmacal Sciences Abstract The controlled drug 3,4-methylenedioxybenzylpiperazine (3,4-MDBP) has regioisomeric and isobaric substances of mass equivalence, which have similar analytical properties and thus the potential for misidentification. The direct regioisomers of 3,4-MDBP include the 2,3- methylenedioxy substitution pattern and the indirect regioisomers include the three ring substituted methoxybenzoylpiperazines. The ethoxy and methoxymethyl ring substituted benzylpiperazines constitute the major category of isobaric substances evaluated in this study. The direct and indirect regioisomers of 3,4-MDBP and also isobaric substances related to MDBP were synthesized and compared to 3,4-MDBP by using gas chromatographic and spectrophotometric techniques. The GC-MS studies of the direct regioisomers and isobaric substances of 3,4-MDBP indicated that they can not be easily differentiated by mass spectrometry. The synthesized compounds were converted to their perfluoroacyl derivatives, trifluoroacetyl (TFA), pentafluoropropionyl amides (PFPA) and heptafluorobutryl amides (HFBA), in an effort to individualize their mass spectra and to improve chromatographic resolution. Derivatized 3,4-MDBP was not distingushed from its derivatized regioisomers or isobars using mass spectrometry. No unique fragment ions were observed for the various regioisomeric and the isobaric compounds. -
