CAS No. 367514-87-2
Lurasidone (SM-13496) is a second-generation antipsychotic agent that exhibits full antagonism at dopamine D2 and serotonin 5-HT2A receptors with binding affinities Ki = 1 nM and Ki = 0.5 nM, respectively. It also has high affinity for serotonin 5-HT7 receptors (Ki = 0.5 nM), partial agonist activity at 5-HT1A receptors (Ki = 6.4 nM) and lacks affinity for histamine H1 and muscarinic M1 receptors.

|Description||Lurasidone (SM-13496) is a second-generation antipsychotic agent that exhibits full antagonism at dopamine D2 and serotonin 5-HT2A receptors with binding affinities Ki = 1 nM and Ki = 0.5 nM, respectively. It also has high affinity for serotonin 5-HT7 receptors (Ki = 0.5 nM), partial agonist activity at 5-HT1A receptors (Ki = 6.4 nM) and lacks affinity for histamine H1 and muscarinic M1 receptors.|
Lurasidone is a new atypical antipsychotic in the benzoisothiazoles class of chemicals. Like most second-generation antipsychotics it is a full antagonist at dopamine D2 and serotonin 5-HT2A receptors, and is a partial agonist at 5-HT1A receptors. It has much greater affinity for 5-HT7 subtype receptors than other atypical antipsychotics. Lurasidone also has high affinity for the 5-HT1A subtype, α2c-adrenergic receptors and low affinity for α1-adrenergic receptors. It has minimal affinity for 5-HT2C receptors and negligible affinity for histamine H1 and muscarinic receptors.
|In vivo||Lurasidone is rapidly absorbed, reaching peak concentrations within 1.5–3 hours (tmax) after single and multiple oral doses. Once absorbed, it extensively distributes in tissues and rapidly enters the CNS. Lurasidone has high binding to human plasma albumin and alpha-1-glycoprotein (≥99%). Long-term treatment of schizophrenia with lurasidone has been shown to reduce the risk of relapse. The elimination half-life of lurasidone is about 20-40 h. Mean Cmax and area under the curve (AUC) for lurasidone were approximately threefold and twofold greater, respectively, in a comparison of administration with food v. fasting. Lurasidone absorption is independent of food fat content. Lurasidone is metabolised primarily via CYP3A4. In animal studies, lurasidone penetrated the placental barrier and distributed into the fetus, and was excreted in milk during lactation.|

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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)
*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).
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 )
* 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.
