Cat. No. 2400
Chemical Name: (4R)-4-Hydroxy-1-[(1-methyl-1H-indo
Biological ActivitySelective, high affinity tachykinin NK1 receptor antagonist (Ki = 0.69 nM) that displays 320-fold selectivity for human over rat NK1 receptors. Inhibits substance P-induced contraction of isolated guinea pig trachea (IC50 = 32 nM) and inhibits substance P-induced airway constriction in vivo following i.v. and oral administration.
