scyliorhinin II Usage And Synthesis
Uses
Scyliorhinin II is a selective neurokinin-3 receptor agonist, with a Ki of 2.5 nM for neurokinin-3 receptor in rat cerebral cortex.
in vivo
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].
