Publisher and Date:(SPRINGER WIEN, 2013)A series of 1-[2-((5-methyl/chloro)-2-benzoxazolinone-3-yl)acetyl]-35-diaryl-45-dihydro-1H-pyrazole derivatives were prepared by reacting 2-((5-methyl/chloro)-2-benzoxazolinone-3-yl)acetylhydrazine with appropriate chalcones. The chemical structures of all compounds were confirmed by elemental analyses IR H-1 NMR and ESI-MS. All the compounds were investigated for their ability to selectively inhibit monoamine oxidase (MAO) by in vitro tests. MAO activities of the compounds were compared with ...
Synthesis molecular modeling and in vitro screening of monoamine oxidase inhibitory activities of some novel hydrazone derivatives Authors:Salgin-Goksen, Umut; Gokhan-Kelekçi, Nesrin; Yabanoglu-Ciftci, Samiye; Yelekçi, Kemal; Ucar, Gulberk
Publisher and Date:(SPRINGER WIEN, 2013)Thirteen 2-[2-(5-methyl-2-benzoxazolinone-3-yl)acetyl]-3/4/5-substituted benzylidenehydrazine derivatives were synthesized by reacting 2-(5-methyl-2-benzoxazolinone-3-yl)acetylhydrazine and substituted benzaldehydes in neutral and acid/base catalyzed conditions and a comparison was made in terms of their yields and reaction times. The structures of all compounds were confirmed by IR H-1 NMR C-13 NMR mass spectral data and elemental analyses. All the compounds were investigated for their ability ...
Synthesis of some novel hydrazone and 2-pyrazoline derivatives: Monoamine oxidase inhibitory activities and docking studies Authors:Evranos-Aksoz, Begum; Yabanoglu-Ciftci, Samiye; Ucar, Gulberk; Yelekçi, Kemal; Ertan, Rahmiye
Publisher and Date:(Pergamon-Elsevier Science Ltd, 2014)A novel series of 2-pyrazoline and hydrazone derivatives were synthesized and investigated for their human monoamine oxidase (hMAO) inhibitory activity. All compounds inhibited the hMAO isoforms (MAO-A or MAO-B) competitively and reversibly. With the exception of 5i which was a selective MAO-B inhibitor all derivatives inhibited hMAO-A potently and selectively. According to the experimental K-i values compounds 6e and 6h exhibited the highest inhibitory activity towards the hMAO-A whereas compound ...
