|Description||Apremilast (CC-10004) is a potent and orally active PDE4 and TNF-α inhibitor with IC50 of 74 nM and 77 nM, respectively.|
Apremilast is more potent for inhibition of PDE4 compared with cAMP or cGMP hydrolysing enzymes from other PDE families. Apremilast displays a broad pattern of anti-inflammatory activity in a variety of cell types, inhibits TNF-α, IL-12 and IL-23 production, as well as NK and keratinocyte responses. Apremilast is found to inhibit the zymosan-induced PMN production of IL-8 with IC50 of 94 nM. Apremilast inhibits fMLF-induced PMN CD18 and CD11b expression with IC50 of 390 nM and 74 nM, respectively, and inhibits fMLF-induced adhesion of PMN to HUVECs with IC50 of 150 nM. Apremilast inhibits keratinocyte TNF-αproduction, with no effect on keratinocyte cell viability as measured by intracellular ATP levels.  .
|In vivo||Apremilast is stable in the presence of human microsomes (t1/2 > 60 min). It is 90% protein bound in human plasma. Oral and intravenous administration of it in female rats showed that it have good pharmacokinetics with low clearance, a moderate volume of distribution, and a 64% oral bioavailability. In a LPS-induced TNF-αinhibition model in rats, examined the TNF-α inhibitory ability of Apremilast in vivo, and the ED50 is determined to be 0.03 mg/kg. In another LPS-induced neutrophilia model in rats, Apremilast exhibited an ED50 range from 0.3 mg/kg to 0.9 mg/kg.|
PDE4 inhibitory activity :Cells (1×109) are washed in PBS and lysed in cold homogenization buffer (20 mM Tris-HCl, pH 7.1, 3 mM 2-mercaptoethanol, 1 mM MgCl2, 0.1 mM EGTA, 1 μM PMSF, 1 μg/mL leupeptin). Following homogenization in a Dounce homogenizer the supematant is collected by centrifugation and loaded onto a Sephacryl S-200 column equilibrated in homogenization buffer. PDE is eluted in homogenization buffer and the rolipram sensitive fractions pooled and stored in aliquots. Enzyme activity is assayed in 50 mM Tris- HCl, pH 7.5, 5 mM MgCl2 and 1 μM cAMP (of which 1% is3H cAMP) in the presence of varying concentrations of inhibitors. The amount of extract used is pre-determined to ensure that reactions are within the linear range and consumed lessthan15%of the total substrate. Reactions are performed at 30°C for 30 min and terminated by boiling for 2 min. The samples are then chilled and treated with snake 'venom (1mg/mL) at 30 °C for 15 min. Unused substrate is removed by incubation with 200 μL AG1-X8 resin for 15 min. Samples are then spun at 3000 rpm for 5 min and 50 μL of the aqueous phase taken for counting. Eachdata point is carried out in duplicate with activity expressed as percentage of control. IC50 is determined from dose response curves derived from three independent experiments.

For best results, use promptly after mixing.
* 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.

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 MSDS / 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 MSDS / 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.
