Ki: 2.5 nM (Neurokinin-3 receptor)[1]

Scyliorhinin II is a neurokinin-3 selective tachykinin receptor, with a Ki of 2.5 nM for neurokinin-3 (NK-3) receptor in rat cerebral cortex. Scyliorhinin II has little effect on NK-1 and NK-2 receptors, with Ki (NK-1 receptor)/Ki (NK-3 receptor) and Ki (NK-2 receptor)/Ki (NK-3 receptor) of 176 and 200[1].

Scyliorhinin II produces potent, dose-related reciprocal hindlimb scratching about equipotently with an ED50 of 0.08 nmol via intracerebroventricularly (i.c.v.) administration in mice[2].
