In Vitro | In vitro activity: 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. Kinase Assay: Darapladib is a potent inhibitor of lipoprotein-associated phospholipase A2 (Lp-PLA2) with IC50 of 0.25 nM. Cell Assay: Mechanistic studies using steady state and transient kinetics indicate Darapladib (SB-480848) to be a freely reversible, non-covalently bound, inhibitor of rhLp-PLA2 with a Ki of 110 pM and an off-rate of 27 min. Potent inhibition of the enzyme in whole human plasma is confirmed (IC50=5±2 nM). Furthermore, the presence of Darapladib during the copper catalysed oxidation of human LDL prevents the production of lyso-PtdCho (IC50=4±3 nM) and subsequent monocyte chemotaxis (IC50=4±1 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. |
