| Questions And Answer | Back Directory | [Description]
Darapladib (SB-480848) is a reversible lipoprotein-associated phospholipase A2 (Lp-PLA2) inhibitor with IC50 of 0.25 nM. Phase 3. | [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. | [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.

Treatment of atherosclerosis. | [Biological Activity]
plaque rupture is responsible for the clinical events of ischemic death, myocardial infarction, acute coronary syndromes and ischemic strokes. lipoprotein-associated phospholipase a2 (lp-pla2) seems to play a major role in the development of such high-risk lesions, in both the coronary and carotid arteries. darapladib is a selective inhibitor of lp-pla2. | [target]
