Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO Corn oil
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Darapladib is a reversible lipoprotein-associated phospholipase A2 (Lp-PLA2) inhibitor with IC50 of 0.25 nM. Phase 3.
Targets
Lp-PLA2 [1]
(Cell-free assay)
0.25 nM
In vitro

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. [1]
In vivo

In the WHHL rabbits, Darapladib (30 mg/kg p.o.) exhibits excellent inhibition of Lp-PLA2 within the atherosclerotic plaque by 95%. [1]

Darapladib, as an inhibitor of Lp-PLA2, reduces development of advanced coronary atherosclerosis in diabetic and hypercholesterolemic (DMHC) pigs. [2]

In DMHC pigs, darapladib reduces the amount of IgG-immunopositive material that leaked into the brain and also the density of Aβ42-containing neurons. [3]
