hNK3 13 nM (Ki) |
hNK2 1220 nM (Ki) |
SB 218795 (3-30 nM) antagonizes the contractile responses induced by the NK3 receptor agonist senktide in a surmountable and concentration-dependent manner[2].
SB 218795 (0.3-3 μM) does not affect the contractile responses of the NK3 receptor agonist [MePhe7]-NKB in the rabbit iris sphincter muscle[2].
