Herein, we report a new class of amide-based inhibitors (1-4) of N-methyl-o-aspartate receptors (NMDARs) that were prepared as analogues of pregnanolone sulfate (PAS) and pregnanolone glutamate (PAG) - the steroidal neuroprotective NMDAR inhibitors. A series of experiments were conducted to evaluate their physicochemical and biological properties: (i) the inhibitory effect of compounds 3 and 4 on NMDARs was significantly improved (IC50 = 1.0 and 1.4 mu M respectively) as compared with endogenous inhibitor - pregnanolone sulfate (IC50 = 24.6 mu M) and pregnanolone glutamate (IC50 = 51.7 mu M), (ii) physicochemical properties (logP and logD) were calculated, (iii) Caco-2 assay revealed that the permeability properties of compounds 2 and 4 are comparable with pregnanolone glutamate, (iv) compounds 1-4 have minimal or no adverse hepatic effect, (v) compounds 1-4 cross blood-brain-barrier.
