SB 218795 is a potent and selective non-peptide NK3 receptor antagonist, with a Ki 13 nM for hNK3. SB 218795 shows about 90-fold and 7000-fold selectivity for hNK3 over hNK2 and hNK1, respectively. SB 218795 can inhibit NK3 receptor-mediated pupillary constriction of the rabbit[1][2].
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].
SB 218795 (0.25-1 mg/kg; i.v.) inhibits Senktide-induced miosis in rabbits by the maximum inhibition of 78%[2].
