Biological Activity

Description Lurasidone (SM-13496) is an atypical antipsychotic, inhibits Dopamine D2, 5-HT2A, 5-HT7, 5-HT1A and noradrenaline α2C with IC50 of 1.68 nM, 2.03 nM, 0.495 nM, 6.75 nM and 10.8 nM, respectively.
5-HT7 [1] D2 receptor [1] 5-HT2A [1] 5-HT1A [1] noradrenaline α2C [1]
0.495 nM 1.68 nM 2.03 nM 6.75 nM 10.8 nM
In vitro

Lurasidone antagonizes dopamine-stimulated [35S]GTPγS binding at human dopamine D2L receptor in a concentration-dependent manner with a KB value of 2.8 nM. Lurasidone antagonizes 5-HT-stimulated cAMP accumulation in the CHO/h5-HT7 cells with a KB value of 2.6 nM. Lurasidone partially stimulates [35S]GTPγS binding to the membrane preparation for human 5-HT1A receptors with a maximum effect of 33%. Lurasidone dose-dependently increases the ratio of DOPAC/dopamine in rat frontal cortex and striatum. [1]

In vivo The inhibitory actions of Lurasidone on MAP-induced hyperactivity persists for more than 8 hours, and the ED50 values of the action at 1 hour, 2 hours, 4 hours, and 8 hours after the treatment are 2.3 mg/kg, 0.87 mg/kg, 1.6 mg/kg, and 5.0 mg/kg, respectively. Lurasidone (1 mg/kg–10 mg/kg) dose-dependently inhibits conditioned avoidance response in rats with ED50 of 6.3 mg/kg. Lurasidone dose-dependently inhibits TRY-induced forepaw clonic seizure and p-CAMP-induced hyperthermia in rats with ED50 of 5.6 mg/kg and 3.0 mg/kg, respectively. Lurasidone (0.3 mg/kg–30 mg/kg) dose-dependently and significantly increases the number of shocks received by rats in the Vogel's conflict test with MED of 10 mg/kg. Lurasidone (3 mg/kg, 2 weeks) significantly suppresses hyperactivity behavior in olfactory bulbectomy model rats. Lurasidone (700 mg/kg–1000 mg/kg) slightly prolongs the duration of loss of righting reflexes elicited by hexobarbital (anesthesia) in mice in a dose-dependent manner. [1] Lurasidone (30 mg/kg, p.o.) significantly and dose-dependently reverses the MK-801-induced impairment of the passive-avoidance response of rats. [2] Lurasidone (3 mg/kg p.o.) potently reverses MK-801-induced learning impairment in the Morris water maze test in rats. Lurasidone (3 mg/kg p.o.) potently reverses MK-801-induced reference memory impairment and moderately but not significantly attenuates MK-801-induced working memory impairment in the radial-arm maze test. [3] Lurasidone (10 mg/kg) treatment increases total BDNF mRNA levels in rat prefrontal cortex and, to less extent, in hippocampus. Lurasidone (10 mg/kg) significantly increases the levels of mature BDNF protein in rat prefrontal cortex, without affect the protein levels of the neurotrophin (both precursor and mature forms) in hippocampal extracts.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
