CYCLOHEXANECARBOXAMIDE, N-[2-[4-(2-METHOXYPHENYL)-1-PIPERAZINYL]ETHYL]-N-2-PYRIDINYL-, HYDROCHLORIDE (1:3)

The Uses of CYCLOHEXANECARBOXAMIDE, N-[2-[4-(2-METHOXYPHENYL)-1-PIPERAZINYL]ETHYL]-N-2-PYRIDINYL-, HYDROCHLORIDE (1:3)

WAY 100635 exhibits high affinity and efficacy at the dopamine D4 receptor (1,2,3). WAY 100635 is a potent 5-HT1A antagonist.

Definition

ChEBI: N-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-N-(2-pyridinyl)cyclohexanecarboxamide is a member of piperazines.

Biological Activity

5-ht1a receptors mediate various serotonergic functions and may be implicated in various pathologies including depressive and anxiety disorders, alzheimer’s disease, and schizophrenia. way-100635 is a potential spect ligands for the 5-ht1a receptor.

in vitro

way-100635 displaced specific binding of the 5-ht1a radioligand, [3h]8-oh-dpat, to rat hippocampal membranes with a plc50 of 8.87. in functional assays, way-100635 was a potent 5-ht1a receptor antagonist, with no evidence of any 5-htia receptor agonist or partial agonist activity. in the isolated guinea-pig ileum way-100635 was a potent and, at high concentrations, an insurmountable antagonist of the 5-ht1a receptor agonist action of 5-carboxamidotryptamine, with an apparent pa 2 value (at 0.3 nm) of 9.71 [2].

in vivo

way-100635 blocked the inhibitory action of 8-oh-dpat on dorsal raphe neuronal firing in the anaesthetised rat at doses which had no inhibitory action per se. in behavioural models, way-100635 itself induced no overt behavioural changes but potently antagonised the behavioural syndrome induced by 8-oh-dpat in the rat and guinea-pig (minimum effective dose = 0.003 mg/kg s.c. and id50 = 0.01 mg/kg s.c., respectively). way-100635 also blocked the hypothermia induced by 8-oh-dpat in the mouse and rat with id50 values of 0.01 mg/kg s.c. [2].
