Application

The pharmacodynamics profile of SB 222200 enables its use as a tool to study physiological and pathophysiological roles of NK-3 receptor in CNS-modulated behaviors.

Biochem/physiol Actions

Non-peptide NK3 tachykinin receptor antagonist.
SB 222200 is a 2-phenyl-4-quinolinecarboxamides and a selective, reversible and competitive antagonist of human NK-3 receptor that effectively crosses the blood-brain barrier. It inhibits the NK-3 receptor-induced miosis or pupil constriction in conscious rabbits.1,2

Are neurokinin B (NKB), NK3 receptor (NK3R), kisspeptin (KISS1) and kisspeptin receptor (KISS1R) expressed in human ovarian granulosa cells? The NKB/NK3R and kisspeptin/KISS1R systems are co-expressed and functionally active in ovarian granulosa cells. The NKB/NK3R and KISS1/KISS1R systems are essential

The pharmacological and pharmacokinetic profile of SB-222200 [(S)-(-)-N-(alpha-ethylbenzyl)-3-methyl-2-phenylquinoline-4-car boxami de], a human NK-3 receptor (hNK-3R) antagonist, was determined. SB-222200 inhibited (125)I-[MePhe(7)]neurokinin B (NKB) binding to Chinese hamster ovary (CHO) cell membranes stably expressing the hNK-3 receptor (CHO-hNK-3R) with a K(i)

The necessity and functional significance of neurotransmitter co-transmission remains unclear. The glutamatergic 'KNDy' neurons co-express kisspeptin, neurokinin B (NKB), and dynorphin and exhibit a highly stereotyped synchronized behavior that reads out to the gonadotropin-releasing hormone (GnRH) neuron dendrons to drive
