Notes: SB 222200 is a neurokinin-3 (NK3) receptor antagonist (IC50 = 18.4 nM).{48780} It is selective for NK3 over NK1 and NK2 receptors (IC50s = 250 and >100,000 nM, respectively). SB 222200 decreases calcium mobilization induced by neurokinin B (Item No. 24542) with an IC50 value of 265 nM in HEK293 cells expressing the recombinant human receptor. It inhibits contractions induced by senktide (Item No. 16721) in isolated rabbit iris sphincter muscle when used at a concentration of 300 nM. SB 222200 (500 pmol, i.c.v.) decreases mean arterial pressure in spontaneously hypertensive, but not normotensive, rats.{48781} It prevents senktide-induced head shakes and tail whips in mice (ED50 = 5.6 mg/kg).{48780}
