GR 159897 is a highly potent, selective, competitive, brain-penetrated non-peptide antagonist at tachykinin NK2 receptors, inhibits binding of [3H]GR100679 to hNK2-CHO cells and rat colon membranes with pKis of 9.51 and 10, respectively. Antagonizes bronchoconstriction, with anxiolytic-like activity.
