Popis: | Monoamine oxidase (MAO) is an enzyme, present in mammals in two isoforms MAO-A and MAO-B. These isoforms have a crucial role in neurotransmitters metabolism, representing an attractive drug target in the therapy of neurodegenerative diseases (MAO-B) and depression (MAO-A). In this context, our work has been focused on the discovery of new chemical entities (NCEs) for MAO inhibition, based on the development of chromone carboxamides. Chromone derivatives with a carboxamide function located in position 2- and 3- of the benzo-γ-pyrone core, (compounds 2-6 and 8-12) were synthesized, with moderate/good yields, by a one-pot condensation reaction using phosphonium salts as coupling reagents. The synthetic compounds were screened towards human MAO isoforms (hMAO) to evaluate their potency and selectivity. The chromone-3-carboxamides show high selectivity to hMAO-B, with compounds 9 and 12 displaying IC 50 values at nanomolar range. © 2010 Elsevier Ltd. All rights reserved. |
