Cell experiment: | Rat, dog, rhesus monkey, and human plasma samples (3 mL, N=3) are incubated with 2 and 20 uM [14C] Rislenemdaz at 37°C for 30 min in a shaking water bath. Following incubation, standard ultracentrifugation methodology is used to determine the percentage of drug unbind[1]. |
Animal experiment: | Four groups of 24 rats (12/sex) are given single doses of vehicle (0.5% methylcellulose [MC] and 0.02% sodium lauryl sulfate [SLS] in deionized water) or Rislenemdaz at 10, 30 or 100 mg/kg by oral gavage at a dose volume of 10 mL/kg. Three additional groups of rats (four males and three females per group) are orally dosed in the same manner with Rislenemdaz, and 24h serial blood samples are obtained and analyzed for Rislenemdaz plasma concentrations and evaluated for systemic exposure. Young, adult, male rats are randomly assigned across the treatment groups and are administered vehicle (0.5% MC/0.02% SLS), the reference compound desipramine (20 mg/kg; a tricyclic antidepressant) dissolving in sterile water, or Rislenemdaz (0.1, 0.3, 1, 3, 10, and 30 mg/kg) suspending in 0.5% MC/0.02% SLS, twice on Day 1 (after habituation; ~24 h prior to test, and prior to dark cycle) and once on Day 2 (30 min pretest for desipramine and 45 min pretest for Rislenemdaz and vehicle)[1]. |

Novel Glutamatergic Modulators for the Treatment of Mood Disorders: Current Status
The efficacy of standard antidepressants is limited for many patients with mood disorders such as major depressive disorder (MDD) and bipolar depression, underscoring the urgent need to develop novel therapeutics. Both clinical and preclinical studies have implicated glutamatergic system dysfunction in the pathophysiology of mood disorders. In particular, rapid reductions in depressive symptoms have been observed in response to subanesthetic doses of the glutamatergic modulator racemic (R,S)-ketamine in individuals with mood disorders. These results have prompted investigation into other glutamatergic modulators for depression, both as monotherapy and adjunctively. Several glutamate receptor-modulating agents have been tested in proof-of-concept studies for mood disorders. This manuscript gives a brief overview of the glutamate system and its relevance to rapid antidepressant response and discusses the existing clinical evidence for glutamate receptor-modulating agents, including (1) broad glutamatergic modulators ((R,S)-ketamine, esketamine, (R)-ketamine, (2R,6R)-hydroxynorketamine [HNK], dextromethorphan, Nuedexta [a combination of dextromethorphan and quinidine], deudextromethorphan [AVP-786], axsome [AXS-05], dextromethadone [REL-1017], nitrous oxide, AZD6765, CLE100, AGN-241751); (2) glycine site modulators (D-cycloserine [DCS], NRX-101, rapastinel [GLYX-13], apimostinel [NRX-1074], sarcosine, 4-chlorokynurenine [4-Cl-KYN/AV-101]); (3) subunit (NR2B)-specific N-methyl-D-aspartate (NMDA) receptor antagonists (eliprodil [EVT-101], traxoprodil [CP-101,606], rislenemdaz [MK-0657/CERC-301]); (4) metabotropic glutamate receptor (mGluR) modulators (basimglurant, AZD2066, RG1578, TS-161); and (5) mammalian target of rapamycin complex 1 (mTORC1) activators (NV-5138). Many of these agents are still in the preliminary stages of development. Furthermore, to date, most have demonstrated relatively modest effects compared with (R,S)-ketamine and esketamine, though some have shown more favorable characteristics. Of these novel agents, the most promising, and the ones for which the most evidence exists, appear to be those targeting ionotropic glutamate receptors.
A new generation of antidepressants: an update on the pharmaceutical pipeline for novel and rapid-acting therapeutics in mood disorders based on glutamate/GABA neurotransmitter systems
Mood disorders represent the largest cause of disability worldwide. The monoaminergic deficiency hypothesis, which has dominated the conceptual framework for researching the pathophysiology of mood disorders and the development of novel treatment strategies, cannot fully explain the underlying neurobiology of mood disorders. Mounting evidence collected over the past two decades suggests the amino acid neurotransmitter systems (glutamate and GABA) serve central roles in the pathophysiology of mood disorders. Here, we review progress in the development of compounds that act on these systems as well as their purported mechanisms of action. We include glutamate-targeting drugs, such as racemic ketamine, esketamine, lanicemine (AZD6765), traxoprodil (CP-101,606), EVT-101, rislenemdaz (CERC-301/MK-0657), AVP-786, AXS-05, rapastinel (formerly GLYX-13), apimostinel (NRX-1074/AGN-241660), AV-101, NRX-101, basimglurant (RO4917523), decoglurant (RG-1578/RO4995819), tulrampator (CX-1632/S-47445), and riluzole; and GABA-targeting agents, such as brexanolone (SAGE-547), ganaxolone, and SAGE-217.
Ketamine and Other Glutamate Receptor Modulating Agents for Treatment-Resistant Depression: A Systematic Review of Randomized Controlled Trials
Objective: Available treatments of depression have limited efficacy and unsatisfactory remission rates. This study aims to review randomized controlled trials (RCTs) investigating effects of glutamate receptor modulators in treating patients with resistant depression. Method : The study protocol was registered in PROSPERO (CRD42021225516). Scopus, ISI Web of Science, Embase, Cochrane Library, Google Scholar, and three trial registries were searched up to September 2020 to find RCTs evaluating glutamate receptor modulators for resistant depression. The difference between intervention and control groups in changing depression scores from baseline to endpoint was considered the primary outcome. Version 2 of the Cochrane risk-of-bias tool for randomized trials was used to assess the quality of the RCTs. No funding was received. Results: Thirty-eight RCTs were included. Based on the included studies, compelling evidence was found for ketamine (with or without electroconvulsive therapy, intravenous or other forms), nitrous oxide, amantadine, and rislenemdaz (MK-0657); the results for MK-0657, amantadine, and nitrous oxide were only based on one study for each. Lithium, lanicemine, D-cycloserine, and decoglurant showed mixed results for efficacy, and, riluzole, and 7-chlorokynurenic acid were mostly comparable to placebo. A limited number of studies were available that addressed drugs other than ketamine. Conclusion: The study cannot determine the difference between statistical and clinical significance between the agents and placebo due to high heterogeneity among the RCTs. Nevertheless, ketamine could be used as an efficacious drug in TRD; still, additional studies are needed to delineate the optimum dosage, duration of efficacy, and intervals. Further studies are also recommended on the effectiveness of glutamatergic system modulators other than ketamine on treatment-resistant depression.
Rislenemdaz treatment in the lateral habenula improves despair-like behavior in mice
The specific GluN2B antagonist rislenemdaz (Ris; a.k.a. MK-0657 and CERC-301) is in phase II clinical trial as an antidepressive drug, but the working mechanism for its antidepressant effects is not clearly understood. Given the important role of the lateral habenula (LHb) in the pathogenesis of depression and the fact that GluN2B-containing N-methyl-D-aspartate receptors and brain-derived neurotrophic factor (BDNF) are expressed in the LHb, we conducted a study to examine whether the LHb mediates Ris' antidepressant effects in a chronic restraint stress (CRS)-induced depressive-like mouse model. In this study, Ris was administered systemically or locally into the LHb. Short hairpin RNAs were used to knockdown BDNF in the LHb. Depressive-like behaviors were assessed with the open field test, forced swimming test, tail suspension test, and sucrose preference test. Expression of GluN2B, BDNF, and c-Fos in the LHb were analyzed with western blotting and immunohistochemistry under condition with Ris administered systemically or with BDNF knockdown in the LHb. We found that both systemic and intra-LHb administration of Ris alleviated CRS-induced despair-like behavior and that systemic Ris reduced LHb expression of GluN2B, BDNF, and c-Fos (a neuronal activity marker). Specific knockdown of BDNF in the LHb prevented CRS-induced despair-like behavior, while preventing CRS-induced increases in BDNF and c-Fos expression in the LHb. Together these results suggest that Ris may exert its antidepressant effects through affecting the LHb such as downregulating BDNF expression in the LHb.
