Absolute configuration and biological profile of pyrazoline enantiomers as MAO inhibitory activity
Goksen, Umut Salgin; Sarıgül, Sevgi; Bultinck, Patrick; Herrebout, Wouter; Doğan, İlknur; Yelekçi, Kemal; Uçar, Gülberk; Kelekçi, Nesrin Gökhan (Wiley, 2019)A new racemic pyrazoline derivative was synthesized and resolved to its enantiomers using analytic and semipreparative high-pressure liquid chromatography. The absolute configuration of both fractions was established using ... -
Design and synthesis of novel 2-pyrazoline analogues and their hMAO inhibitory activities
Uçar, Gülberk; Evranos-Aksoz, Begum; Yabanoglu-Çiftçi, Samiye; Yelekçi, Kemal (Wiley-Blackwell, 2015)[Abstract Not Available] -
Design, Synthesis and hMAO Inhibitory Screening of Novel 2-Pyrazoline Analogues
Evranos-Aksöz, Begüm; Uçar, Gülberk; Yelekçi, Kemal (Bentham Science Publ Ltd, 2017)Aim and Objective: MAO inhibitors have a significant effect on the nervous system since they act in regulation of neurotransmitter concentrations. Neurotransmitter levels are critical for a healthy nervous system. MAO ... -
Flavonoids from Sideritis Species: Human Monoamine Oxidase (hMAO) Inhibitory Activities Molecular Docking Studies and Crystal Structure of Xanthomicrol
Türkmenoğlu, Fatma Pınar; Baysal, Ipek; Çiftçi-Yabanoğlu, Samiye; Yelekçi, Kemal; Temel, Hamdi; Paşa, Salih; Ezer, Nurten; Çalış, Ihsan; Uçar, Gülberk (MDPI, 2015)The inhibitory effects of flavonoids on monoamine oxidases (MAOs) have attracted great interest since alterations in monoaminergic transmission are reported to be related to neurodegenerative diseases such as Parkinson's ... -
New Human Monoamine Oxidase A Inhibitors with Potential Anti- Depressant Activity: Design, Synthesis, Biological Screening and Evaluation of Pharmacological Activity
Evranos Aksöz, Begüm; Uçar, Gülberk; Taş, Sadık Taşkın; Aksöz, Erkan; Yelekçi, Kemal; Erikçi, Açelya; Sara, Yıldırım; İskit, Alper Bektaş (Bentham Science, 2017)Aim and objective: Depression is a momentous disease that can greatly reduce the quality of life and cause death. In depression, neurotransmitter levels such as serotonine, dopamine and noradrenaline are impaired. Monoamine ... -
