TL;DR: Using the functional cell-based assay Receptor Selection and Amplification Technology (R-SAT((R))), a screening effort identified three small molecule chemotypes (AC-94544, AC-88324, and AC-110484) with selective agonist activity at the V(2) receptor.

30 Jan 2013TL;DR: Combinations of 5-HT2A inverse agonists or antagonists such as pimavanserin with antipsychotics such as risperidone are shown to induce a rapid onset of antipsychotic action and increase the number of responders when compared to therapy with the anti-psychotic alone.
Abstract: Combinations of 5-HT2A inverse agonists or antagonists such as pimavanserin with antipsychotics such as risperidone are shown to induce a rapid onset of antipsychotic action and increase the number of responders when compared to therapy with the antipsychotic alone. These effects can be achieved at a low dose of the antipsychotic, thereby reducing the incidence of side effects. The combinations are also effective at decreases the incidence of weight gain and increased glucose or prolactin levels caused by the antipsychotic.

TL;DR: A series of potential antipsychotic agents with a novel receptor activity profile comprised of muscarinic M1 receptor agonism in addition to dopamine D2 antagonism and serotonin 5-HT2A inverse agonism are developed and demonstrate pro-cognitive actions in the novel object recognition assay.
Abstract: Current antipsychotic drug therapies for schizophrenia have limited efficacy and are notably ineffective at addressing the cognitive deficits associated with this disorder. The present study was designed to develop effective antipsychotic agents that would also ameliorate the cognitive deficits associated with this disease. In vitro studies comprised of binding and functional assays were utilized to identify compounds with the receptor profile that could provide both antipsychotic and pro-cognitive features. Antipsychotic and cognitive models assessing in vivo activity of these compounds included locomotor activity assays and novel object recognition assays. We developed a series of potential antipsychotic agents with a novel receptor activity profile comprised of muscarinic M1 receptor agonism in addition to dopamine D2 antagonism and serotonin 5-HT2A inverse agonism. Like other antipsychotic agents, these compounds reverse both amphetamine and dizocilpine-induced hyperactivity in animals. In addition, unlike other antipsychotic drugs, these compounds demonstrate pro-cognitive actions in the novel object recognition assay. The dual attributes of antipsychotic and pro-cognitive actions distinguish these compounds from other antipsychotic drugs and suggest that these compounds are prototype molecules in the development of novel pro-cognitive antipsychotic agents.

31 Oct 2006TL;DR: In this article, the authors describe compounds that are prodrugs to active compounds that modulate a muscarinic receptor, such as N-desmethylclozapine.
Abstract: Compounds are described that are prodrugs to active compounds that modulate a muscarinic receptor. In some cases, the compounds are prodrugs to N-desmethylclozapine. The compounds may be used to treat neuropsychiatric disorders.

TL;DR: Adjunctive pimavanserin significantly improved sleep/wakefulness disturbance during treatment of MDD, an improvement that was associated with greater improvement in function.
Abstract: Objective This was an analysis of the effect of pimavanserin, a 5-hydroxytryptamine-2A antagonist and inverse receptor agonist, on dysregulated sleep in patients with major depressive disorder (MDD) by DSM-5 criteria and an inadequate antidepressant response. Methods For this analysis of CLARITY, a phase 2 study of adjunctive pimavanserin (N = 207) conducted between December 2016 and October 2018, sleep/wakefulness disturbances were measured with the 17-item Hamilton Depression Rating Scale (HDRS₁₇) insomnia items (sum of items 4, 5, and 6) and the Karolinska Sleepiness Scale (KSS). Outcomes included change from baseline in HDRS₁₇ insomnia factor score and KSS score, correlation between the HDRS₁₇ insomnia factor score and KSS score, and change from baseline in the Sheehan Disability Scale (SDS) total score and Unproductive Days subscore in patients with a baseline KSS score ≥ 6. Results At baseline, HDRS₁₇ insomnia factor score ≥ 3 occurred in 76% of patients receiving placebo and 85% of patients receiving pimavanserin. The overall least squares (LS) mean weighted difference (SE) was -0.5 (0.32) with a 95% CI of -1.2 to 0.1 (P = .088) at week 5. Improvement was observed with pimavanserin versus placebo at weeks 2, 3, and 4, with effect sizes (ESs) of 0.370 to 0.524 (P Conclusions Adjunctive pimavanserin significantly improved sleep/wakefulness disturbance during treatment of MDD, an improvement that was associated with greater improvement in function. Trial registration ClinicalTrials.gov identifier: NCT03018340.
