Biochem/physiol Actions

EU1794-4 consists of an ethyl ester and lacks a methyl substituent on the tetrahydrobenzothiophene core.
EU1794-4 is an N-methyl-d-aspartate (NMDA) receptor (NMDAR) allosteric modulator that prevents large degree receptor activation in the presence of high level Glu/Gly (IC50/Emax = 2.2 μM/32%/GluN2A, 2.6 μM/67%/GluN2B, 0.42 μM/52%/GluN2C, 0.36 μM/51%/GluN2D with Glu/Gly = ECmax = 100/30 μM using xenopus oocytes co-expressing rat GluN1 and respective GluN2 subtype), while augmenting receptor activation at low level Glu/Gly (EC50/Emax = 3.9 μM/500%/GluN2A, 4.3 μM/210%/GluN2B, 15 μM/220%/GluN2C with Glu/Gly = 1/0.3 μM; 14 μM/540%/GluN2D with Glu/Gly = 300/9 nM).

NMDA receptors mediate a slow Ca(2+)-permeable component of excitatory synaptic transmission, and are involved in numerous normal brain functions including learning and memory. NMDA receptor over-activation can lead to cell death and abnormal excitation in ischemia associated with stroke, traumatic

Secreted frizzled related protein-1 (sFRP-1) inhibitors have the potential to be used for the treatment of osteoporosis or other bone related disorders, since the level of sFRP-1 affects osteoblast apoptosis and proliferation. From high throughput screening, we have identified a

N-methyl-d-aspartate receptors (NMDARs) are an important receptor in the brain and have been implicated in multiple neurological disorders. Many non-selective NMDAR-targeting drugs are poorly tolerated, leading to efforts to target NMDAR subtypes to improve the therapeutic index. We describe here
