Schizophrenia

RenaSci offers a range of assays that can be used to develop compounds to treat schizophrenia and related disorders. Compounds can be evaluated in well-established dopaminergic or hypoglutamatergic hyperactivity assays. They can also be assessed in the conditioned avoidance assay; selective disruption of the conditioned response is a characteristic property of both typical and novel antipsychotic agents.

  • Amphetamine or PCP induced locomotor activity.
  • Antipsychotic drugs reverse the hyperactivity induced by amphetamine or PCP in mice and rats

  • Conditioned Avoidance Response – Typical and novel antipsychotic agents selectively inhibit the conditioned response in rats without affecting the unconditioned response. The efficacy of a drug to suppress conditioned avoidance responding in rats correlates with its ability to reduce psychosis in man. The conditioned avoidance response test is a crucial model in development of drugs to treat schizophrenia

  • DOI-induced head twitch in mice: many novel antipsychotic agents inhibit DOI-induced head twitch indicating an interaction with the serotonergic system

  • Drug-induced catalepsy in rodents is an assay predictive of extrapyramidal side effects in man

  • Weight gain is a serious side-effect of antipsychotic treatment. We have developed a rat model of antipsychotic weight gain

  • Increased plasma prolactin is a side-effect of antipsychotic drugs. We offer a plasma prolactin assay that can assess whether novel drugs to treat schizophrenia increase circulating levels of prolactin
