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.

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

Major depressive disorder (MDD) is one of the most disabling psychiatric disorders in the world. First-line treatments such as selective serotonin reuptake inhibitors (SSRIs) still have many limitations, including a resistance to treatment in 30% of patients and a delayed

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

Although considerable progress has been made in characterising the 5-HT1A receptor using agonists, partial agonists or non-selective antagonists, further studies of 5-HT1A receptor function have been hindered by the lack of highly selective antagonists. The term 'silent' antagonist has been
