Ketamine displays efficacious rapid-acting antidepressant (RAAD) activity in the rat chronic mild stress (CMS) model. It rapidly reverses anhedonia (CMS-induced sucrose consumption deficit) and attenuates working memory deficit (novel object recognition: NOR) following both systemic (intraperitoneal, i.p.) administration or local administration in the prefrontal cortex (PFC). However, the...
The highly selective 5-HT1A serotonin receptor "biased" agonists NLX-101 and NLX-204 display, like ketamine, potent and efficacious rapid-acting antidepressant (RAAD) activity in the rat chronic mild stress (CMS) model with systemic (i.p.) administration. They rapidly (within 1 day) reverse anhedonia (i.e., CMS-induced sucrose consumption deficit), attenuate working memory deficit (novel object...
NLX-101 and NLX-204 are highly selective serotonin 5-HT1A ‘biased’ agonists, displaying potent and efficacious antidepressant-like activity upon acute administration in models such as the forced swim test. we compared the effects of repeated administration of NLX-101, NLX-204 and ketamine in the chronic mild stress (CMS) model of depression, considered to have high translational potential, on...
