A simple, accurate, and precise HPLC method was developed and validated for determination of rimonabant in human plasma. Following liquid-liquid extraction, chromatographic separation was accomplished using C18 column with mobile phase consisting of acetonitrile : water (90 : 10, v/v), drug was detected at 260 nm using UVdetector. The LOD and LOQ were 3.0 and 10.0 μg/L, respectively. The method is linear in the interval 50.0-1000.0 μg/L. The average extraction recovery of drug from plasma was found to be 92.2%. The percent CV of the method was found to be less than 10.8%, and accuracy was found between 94.5 and 106.7%. The assay may be applied to a pharmacokinetic and bioequivalence study of rimonabant.

Ketamine (KET) is recognized as rapid-acting antidepressant, but its mechanisms of action remain elusive. Considering the role of endocannabinoids (eCB) in stress and depression, we investigated if S-KET antidepressant effects involve the regulation of the eCB system using an established rat model of depression based on selective breeding: the Flinders Sensitive Line (FSL) and their controls, the Flinders Resistant Line (FRL). S-KET (15 mg/kg) effects were assessed in rats exposed to the open field and forced swimming test (FST), followed by analysis of the eCB signaling in the rat prefrontal cortex (PFC), a brain region involved in depression neurobiology.

Clinically, patients with depression are at a heightened risk for developing epilepsy, and vice versa, suggesting shared mechanisms for this bidirectional comorbidity. Unfortunately, comorbid depression and epilepsy is associated with worsened quality of life and treatment refractoriness, highlighting the need for novel treatment targets and nonpharmacologic supplements to existing therapies. The present study used the Swim-Low Active rat, a well-validated model of depression and epilepsy comorbidity that was selectively bred based on forced swim test behavior, to assess the safety and efficacy of caloric restriction in treating this comorbidity.

Anxiety disorder is one of the most common neuropsychiatric disorders, and affects many people's daily activities. Although the pathogenesis and treatments of anxiety disorder have been studied for several decades, the underlying mechanisms remain elusive. Here, we provide evidence that olfactory stimuli with inhaled linalool or 2-phenylethanol decreased mouse anxiety-like behaviors and increased the activities of hippocampal dentate granule cells (DGCs).

Rationale: The newly emerging synthetic cannabinoids (SCs) 5F-EDMB-PICA, CUMYL-PEGACLONE, and NM-2201 have been observed to produce effects by activating cannabinoid type 1 (CB1) receptors. Nevertheless, the pharmacological effects and potential for abuse of these three substances remain to be studied. These substances have yet to be regulated in many countries.
