ABSTRACT
In recent studies, monoamine oxidase (MAO) inhibitory effects of various thiazolylhydrazone derivatives have been demonstrated. Within the scope of this study, 12 new compounds containing thiazolylhydrazone groups were synthesized. The structures of the obtained compounds were elucidated by 1H NMR, 13C NMR, and high-resolution mass spectrometry (HRMS) methods. The inhibitory effects of the final compounds on MAO enzymes were investigated by means of in vitro methods. In addition to enzyme inhibition studies, enzyme kinetic studies of compounds with high inhibitory activity were examined, and their effects on substrate-enzyme relations were investigated. Additionaly, cytotoxicity tests were carried out to determine the toxicities of the selected compounds, and the compounds were found to be nontoxic. The interactions of the active compound with the active site of the enzyme were characterized by in silico methods.
