Biological Activity

[Description]:

NS3763 is a selective and noncompetitive GLUK5 receptor antagonist with an IC50 of 1.6 µM. NS3763 does not show significant antagonistic properties on GLUK6, AMPA or NMDA receptors[1].

[Target]

IC50: 1.6 µM (GLUK5 receptor)[1]

[In Vitro]

In human embryonic kidney HEK293 cells expressing homomeric GLUK5 or GLUK6 receptors, NS3763 displays selectivity for inhibition of domoate-induced increase in intracellular calcium mediated through the GLUK5 subtype (IC50 = 1.6 µM) of kainate receptors compared with the GLUK6 subtype (IC50 > 30 µM)[1]. NS3763 selectively inhibits l-glutamate- and domoate-evoked currents through GLUK5 receptors in HEK293 cells[1].
