What is FK 888?
The Uses of FK 888
FK 888 is a neurokinin NK1 receptor antagonist, which is active both in vivo and in vitro.
Definition
ChEBI: (2S,4R)-4-hydroxy-1-[(1-methyl-3-indolyl)-oxomethyl]-N-[(2S)-1-[methyl-(phenylmethyl)amino]-3-(2-naphthalenyl)-1-oxopropan-2-yl]-2-pyrrolidinecarboxamide is a peptide.
Biological Activity
Selective, high affinity tachykinin NK 1 receptor antagonist (K i = 0.69 nM) that displays 320-fold selectivity for human over rat NK 1 receptors. Inhibits substance P-induced contraction of isolated guinea pig trachea (IC 50 = 32 nM) and inhibits substance P-induced airway constriction in vivo following i.v. and oral administration.
