|Description||Darapladib (SB-480848) is a reversible lipoprotein-associated phospholipase A2 (Lp-PLA2) inhibitor with IC50 of 0.25 nM. Phase 3.|
During the copper catalysed oxidation of human LDL, Darapladib prevents the production of lyso-PtdCho with IC50 of 4 nM and subsequent monocyte chemotaxis with IC50 of 4 nM. 
|In vivo||In the WHHL rabbits, Darapladib (30 mg/kg p.o.) exhibits excellent inhibition of Lp-PLA2 within the atherosclerotic plaque by 95%.  Darapladib, as an inhibitor of Lp-PLA2, reduces development of advanced coronary atherosclerosis in diabetic and hypercholesterolemic (DMHC) pigs.  In DMHC pigs, darapladib reduces the amount of IgG-immunopositive material that leaked into the brain and also the density of Aβ42-containing neurons. |

* 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.
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.
