This study investigated the effects of rimonabant (SR141716), an antagonist of the cannabinoid receptor type 1 (CB1), on obesity-associated hepatic steatosis and related features of metabolic syndrome: inflammation (elevated plasma levels of tumor necrosis factor alpha [TNFalpha]), dyslipidemia, and reduced plasma levels of adiponectin. We report that oral treatment of obese (fa/fa) rats with rimonabant (30 mg/kg) daily for 8 weeks abolished hepatic steatosis. This treatment reduced hepatomegaly, reduced elevation of plasma levels of enzyme markers of hepatic damage (alanine aminotransferase, gamma glutamyltransferase, and alkaline phosphatase) and decreased the high level of local hepatic TNFalpha currently associated with steatohepatitis.

Its effects were assessed at the transcriptional level both in white (WAT) and brown (BAT) adipose tissues in a diet-induced obesity model in mice. Our data clearly indicated that SR141716 reversed the phenotype of obese adipocytes at both macroscopic and genomic levels.

- A new compound called SSR504734 helps increase levels of a chemical called glycine in the brain, which might help with treating symptoms of schizophrenia.
- Schizophrenia-like symptoms can be caused when a specific brain connection (glutamatergic transmission) is impaired, and SSR504734 works by blocking a protein that usually keeps glycine levels low.
- In experiments, SSR504734 showed it could improve brain activity and behaviors in mice and rats that are models for schizophrenia, suggesting it could be a good candidate for treatment.
Since vasopressin has been shown to be critical for adaptation of the hypothalamo-pituitary-adrenal axis during stress through its ability to potentiate the stimulatory effect of CRF, it has been hypothesized that this peptide may provide a good opportunity for pharmacological treatment of stress-related disorders. The availability of the first orally active non-peptide V(1b) receptor antagonist, SSR149415, opened a new era for examining the role of vasopressin in animal models of anxiety and depression. In rats, SSR149415 blocked several endocrine (i.

In this study, ethanol preference was investigated in chronically alcoholized rats that underwent regular withdrawal periods during which the brain cannabinoid CB(1) receptor antagonist, SR141716A, was administered.
Methods: The cannabinoid receptor antagonist SR141716A, 3 or 10 mg/kg/day, was administered i.
