NMDA receptor antagonists have potential for therapeutics in neurological and psychiatric diseases, including neurodegenerative epilepsy, traumatic brain injury, substance abuse disorder (SUD), major depressive (MDD). (S)-ketamine was the first of a novel class antidepressants, rapid-acting to be approved medical use. The stereoisomer, (R)-ketamine (arketamine), is currently under development treatment-resistant depression (TRD). compound has demonstrated efficacy multiple animal models. Two clinical studies disclosed TRD bipolar depression. A study by drug sponsor recently failed reach priori endpoints but post hoc analysis revealed efficacy. value supported experimental data humans rodents, showing that it less sedating, does not produce marked psychotomimetic or dissociative effects, than (S)-ketamine, produces models range disorders. mechanisms action antidepressant effects are hypothesized due antagonism and/or non-NMDA mechanisms. We suggest further experimentation with will create improved medicines some disorders underserved current medications.

Ketamine, a dissociative anesthetic, is widely utilized in both human and veterinary anesthesia. Its (S)-enantiomer, esketamine, similarly employed for anesthesia analgesia. The anesthetic effects of ketamine esketamine arise from their antagonism the N-methyl-D-aspartate receptor (NMDAR). In field psychiatry, rapid-acting antidepressant properties severe depression have generated significant interest, resulting its increased off-label usage United States (U.S.). 2019, nasal spray received approval use U.S. Europe. However, concerns emerged regarding potential adverse effects, including long-term efficacy, addiction risks, suicide risk clinical settings. contrast, arketamine, (R)-enantiomer ketamine, exhibits superior longer-lasting rodent models depression, with fewer side compared to esketamine. Nevertheless, research on efficacy safety arketamine patients remains limited. This article provides concise exploration historical two enantiomers while also delving into future directions application these fields.

Sirt6-mediated gut microbiota plays a vital role in poststroke depression (PSD). Icariside Ⅱ (ICS Ⅱ) is naturally-occurring neuroprotectant with Sirt6 induction potency. However, it unknown whether ICS protects against PSD through modulation of microbiota. This study aimed to reveal the effect and potential mechanisms on PSD, microbiota-gut-brain axis was investigated. Using middle cerebral artery occlusion (MCAO) chronic unpredictable mild stress (CUMS) establish post-stroke (PSD) mice, we assessed anti-depressant effects via behavioral tests, immunohistochemistry, western blot. Transcriptome profiling, molecular docking, surface plasmon resonance were used identify key targets. 16S rDNA genomic-derived taxonomic profiling fecal transplantation (FMT) conducted figure out mechanistic short-chain fatty acids (SCFAs). ameliorated depressive-like behaviors mice as evidenced by sucrose preference test, forced swimming test tail suspension test. restored mitochondrial function, reduced oxidative damage pro-inflammatory cytokines both brain intestine regulation Sirt6/NF-κB pathway. significantly increased abundance (such asAkkermansia Ligilactobacillus), enhanced SCFAs concentrations, repaired intestinal barrier integrity upreglated tight junction protein expression. FMT from II-treated replicated these benefits, confirming microbiota's role. Mechanistically, directly bound its activity. Ⅱ-mediated neuroprotection neutralized or hydrogen peroxide-induced enteric glial cells when absent. Our findings expand pharmacological properties II demonstrating ability ameliorate axis. Ⅱ, novel activator, could be translated into an alternative microbiota-targeted avenue for coping PSD.
