Abstract

In the last decades, selenium-containing compounds have received increasing attention due to their various biological and pharmacological properties. In the present study, we investigated the effects of 3-[(4-methoxyphenyl) selanyl]-2-phenylimidazo[1,2-a] pyridine (MPI; 1, 10 or 50 mg/kg, i.g.) on the acute restraint stress (ARS)-induced depressive- and anxiety-like behaviors in mice and its underlying mechanism of action. We used the open filed test, forced swimming test, and splash test to evaluate depressive-like behavior, and marble burying and elevated plus maze test to measure anxiety-like behavior. We found that MPI attenuated ARS-induced depressive- and anxiety-like behaviors in all behavioral tests, without having an effect in non-stressed mice. MPI prevented the increased in pro-inflammatory cytokines, indoleamine-2,3-dioxygenase (IDO) and inducible nitric oxide synthase (iNOS) expression in brain structures via canonical nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) down-regulation. Additionally, MPI prevented ARS-induced downregulation of brain-derived neurotrophic factor (BDNF), increased reactive oxygen/nitrogen species generation and lipid peroxidation in prefrontal cortex and hippocampus of mice. In addition, MPI blocked the downregulation of glucocorticoid receptors in the prefrontal cortex and hippocampus and reduced the increased circulating level of corticosterone in stressed mice. These results suggested that MPI showed antidepressant- and anxiolytic-like properties and the effects might be associated with the biological changes in the prefrontal cortex and hippocampus.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
