Abstract: N-Methyl-d-aspartate receptors (NMDARs) are glutamate-gated Na+ and Ca2+-permeable ion channels involved in excitatory synaptic transmission and synaptic plasticity. NMDAR hypofunction has long been implicated in the pathophysiology including major depressive disorders (MDDs). Herein, we report a series of furan-2-carboxamide analogues as novel NMDAR-positive allosteric modulators (PAMs). Through structure-based virtual screen and electrophysiological tests, FS2921 was identified as a novel NMDAR PAM with potential antidepressant effects. Further structure-activity relationship studies led to the discovery of novel analogues with increased potentiation. Compound 32h caused a significant increase in NMDAR excitability in vitro and impressive activity in the forced swimming test. Moreover, compound 32h showed no significant inhibition of hERG or cell viability and possessed a favorable PK/PD profile. Our study presented a series of novel NMDAR PAMs and provided potential opportunities for discovering of new antidepressants.
