Biological target:
SSR-146977 HCl is an NK3 receptor antagonist (Ki values are 0.26 and 19.3 nM in CHO cells expressing the human NK3 and NK2 receptor, respectively). SSR-146977 HCl also inhibits senktide-induced inositol monophosphate formation and intracellular calcium mobilization (IC50 = 10 nM).
In vitro activity:
To be determined
In vivo activity:
SSR-146977 is a potent and selective antagonist of the tachykinin NK3 receptor. In guinea pigs, SSR-146977 inhibited bronchial hyperresponsiveness to acetylcholine, bronchial microvascular permeability hypersensitivity to histamine, and cough provoked by citric acid. In gerbils, SSR-146977 inhibited turning behavior and prevented the decrease of locomotor activity mediated by the stimulation of NK3 receptors.
