Herein, we report the synthesis, structure-activity relationship study, and biological evaluation of neurosteroid inhibitors of N-methyl-D-aspartate receptors (NMDARs) receptors that employ an amide structural motif, relative to pregnanolone glutamate (PAG) a compound with neuroprotective properties. All compounds were found to be more potent NMDAR inhibitors (IC50 values varying from 1.4 to 21.7 mu M) than PAG (IC50 = 51.7 mu M). Selected compound 6 was evaluated for its NMDAR subtype selectivity and its ability to inhibit AMPAR/GABAR responses. Compound 6 inhibits the NMDARs (8.3 receptors (8.3 +/- 2.1 mu M) more strongly than it does at the GABAR and AMPARs (17.0 receptors (17.0 +/- 0.2 mu M and 276.4 +/- 178.7 mu M, respectively). In addition, compound 6 (10 mu M) decreases the frequency of action potentials recorded in cultured hippocampal neurons. Next, compounds 3, 5-7, 9, and 10 were not associated with mitotoxicity, hepatotoxicity nor ROS induction. Lastly, we were able to show that all compounds have improved rat and human plasma stability over PAG.
