Description: | Lurasidone is an antagonist of both dopamine D2 and 5-HT7 with IC50s of 1.68 and 0.495 nM, respectively. Lurasidone is also a partial agonist of 5-HT1A receptor with an IC50 of 6.75 nM. |
In Vivo: | Lurasidone dose-dependently increases the ratio of DOPAC/dopamine in both regions, but it shows a preferential effect on the frontal cortex compare with the striatum, especially at higher doses. Lurasidone (ED50 values 2.3 to 5.0 mg/kg) shows a comparable potency with olanzapine (ED50 values 1.1 to 5.1 mg/kg), higher potency than clozapine (ED50 9.5 to 290 mg/kg), and slightly lower potency than haloperidol (ED50 values 0.44 to 1.7 mg/kg). Lurasidone (1 to 10 mg/kg) dose-dependently inhibits conditioned avoidance response (CAR) in rats, and the ED50 values are 6.3 mg/kg. Lurasidone dose-dependently inhibits TRY-induced forepaw clonic seizure and p-CAMP-induced hyperthermia with ED50 values of 5.6 and 3.0 mg/kg, respectively. Lurasidone (0.3 to 30 mg/kg) dose-dependently and significantly increases the number of shocks received by rats in the conflict test with MED of 10 mg/kg (p<0.01)[1]. |
In Vitro: | Lurasidone is an antagonist of dopamine D2 and 5-HT7 with IC50s of 1.68±0.09 and 0.495±0.090 nM, respectively. Lurasidone is also a partial agonist of 5-HT1A receptor with an IC50 of 6.75±0.97 nM. In vitro receptor binding experiments reveal that Lurasidone demonstrates affinity for dopamine D2 and 5-HT2A receptors higher than other tested antipsychotics. Lurasidone does not increase [35S]GTPγS binding to the membrane preparations for dopamine D2 receptors by itself, but it antagonizes dopamine-stimulated [35S]GTPγS binding in a concentration-dependent manner with a KB value of 2.8±1.1 nM[1]. |
Kinase Assay: | [35S]GTPγS binding experiments for the human dopamine D2L or 5-HT1A receptors stably expressed in the membranes of recombinant Chinese hamster ovary (CHO) cells are performed. Shortly after dopamine (or serotonin) and/or Lurasidone are incubated for 20 min at room temperature with the cell membrane preparation containing [35S]GTPγS (0.05 nM for D2L or 0.2 nM for 5-HT1A), the membranes are filtered through glass filters and the radioactivity bound to each filter is measured with a liquid scintillation counter[1]. |
Animal Administration: | SD rats are individually isolated in clear plastic cages and injected with methamphetamine (MAP) (1 mg/kg i.p.) 1 h after the administration of drugs or vehicle. In the test of persistence of the effect, Lurasidone is administered 1, 2, 4, and 8 h before the MAP injection. Locomotor activity is measured for 80 min from 10 min after MAP injection. Four or five groups of 6 to 13 rats are used to calculate the ED50 value that inhibits MAP-induced hyperactivity by 50% of the animals tested[1]. |
