RO5328673
RO5328673 is an orally active, blood-brain barrier permeable neurokinin receptor antagonist that effectively targets human NK3 receptors (Ki=0.4 nM, Ka=0.1 nM), human NK2 receptors (Ki=1.1 nM, Ka=0.9 nM), and guinea pig NK3 receptors (Ka=0.1 nM and 0.13 nM). RO5328673 acts as an insurmountable antagonist of NK3 receptors with a slow dissociation rate, while it shows rapid association and dissociation rates at human NK2 receptors. RO5328673 potently inhibits senktide (HY-P0187)-induced enhancement of spontaneous activity in dopaminergic neurons and reverses senktide-induced changes in motor activity of gerbils. RO5328673 is widely applicable to research related to schizophrenia.

Biological Activity
|
hNK2 1.1 nM (Ki) |
hNK3 0.4 nM (Ki) |
RO5328673 (0.0003-10 μM) binds to hNK2 and hNK3 receptors with high affinity, with corresponding Ki values of 1.1 nM and 0.4 nM, respectively, while it shows weak affinity for the hNK1 receptor (Ki=52.8 nM)[1].
[3H]RO5328673 (0.01-20 nM; 23 °C for hNK2, hNK3, gpNK3 or 37 °C for gpNK3) binds with high affinity to a single saturable site on hNK2, hNK3 and gpNK3 receptors, and its binding to gpNK3 is temperature-independent[1].
RO5328673 (1-300 nM; 20 min) acts as an insurmountable antagonist of hNK3 and gpNK3 receptors, which reduces the maximal response intensity and potency of [MePhe7]NKB, with a stronger effect on gpNK3[1].
