Application

WAY-100635 maleate salt has been used as a 5-HT1A serotonin receptor antagonist:
  • to study whether the behavior of the cleaner wrasse is regulated by serotonin activity
  • to block activity of 3,4 methylenedioxymethamphetamine (MDMA) used to induce oxytocin release in male Wistar rats to increase their social behavior
  • to study the role of serotonin during metamorphosis of the ascidian Phallusia mammillata larvae

Biochem/physiol Actions

WAY-100635 maleate salt is a highly selective 5-HT1A serotonin receptor antagonist. It has an ability to inhibit brexpiprazole, an antipsychotic drug that regulates serotonin-dopamine activity.

WAY-100635 (N-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-N-(2- pyridinyl)cyclohexanecarboxamide trihydrochloride) is an achiral phenylpiperazine derivative that binds with high affinity and selectivity to the 5-HT1A receptor. WAY-100635 displaced specific binding of the 5-HT1A radioligand, [3H]8-OH-DPAT (8-hydroxy-2-(di-n-propylamino)tetralin), to rat hippocampal membranes with a pIC50 of 8.87. This

Firing activity of serotonin (5-HT) neurons in the dorsal raphe nucleus (DRN) is controlled by inhibitory somatodendritic 5-HT1A autoreceptors. This autoinhibitory mechanism is implicated in the etiology of disorders of emotion regulation, such as anxiety disorders and depression, as well

The tritiated derivative of the novel silent 5-HT1A receptor antagonist WAY 100635 [N-(2-(4-(2-methoxyphenyl)-1-piperazinyl)ethyl)-N-(2-pyridinyl) cyclohexane carboxamide] was tested as a potential radioligand of 5-HT1A receptors in the rat brain. Binding assays with membranes from various brain regions showed that [3H]WAY 100635
