New pyrazoline bearing 4(3H)-quinazolinone inhibitors of monoamine oxidase: Synthesis biological evaluation and structural determinants of MAO-A and MAO-B selectivity
Authors:Gökhan-Kelekçi, Nesrin; Koyunoğlu, Semra; Yabanoğlu-Çiftçi, Samiye; Yelekçi, Kemal; Özgen, Özen; Uçar, Gülberk; Erol, Kevser; Kendi, Engin; Yeşilada, Akguel
Publisher and Date:(Pergamon-Elsevier Science Ltd, 2009)A new series of pyrazoline derivatives were prepared starting from a quinazolinone ring and evaluated for antidepressant anxiogenic and MAO-A and -B inhibitory activities by in vivo and in vitro tests respectively. Most of the synthesized compounds showed high activity against both the MAO-A (compounds 4a-4h 4j-4n and 5g-5l) and the MAO-B (compounds 4i and 5a-5f) isoforms. However none of the novel compounds showed antidepressant activity except for 4b. The reason for such biological properties ...

Synthesis and Screening of Human Monoamine Oxidase-A Inhibitor Effect of New 2-Pyrazoline and Hydrazone Derivatives
Authors:Evranos-Aksoz, Begüm; Baysal, İpek; Yabanoğlu-Çiftçi, Samiye; Djikic, Teodora; Yelekçi, Kemal; Uçar, Gülberk; Ertan, Rahmiye
Publisher and Date:(Wiley-VCH Verlag GmbH, 2015)A group of 35-diaryl-2-pyrazoline and hydrazone derivatives was prepared via the reaction of various chalcones with hydrazide compounds in ethanol. Twenty original compounds were synthesized. Ten of these original compounds have a pyrazoline structure nine of these original compounds have a hydrazone structure and one of these original compounds has a chalcone structure. Structural elucidation of the compounds was performed by IR H-1 NMR C-13 NMR mass spectral data and elemental analyses. These ...
