| | DARAPLADIB Usage And Synthesis |
| 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.
| | Uses | Treatment of atherosclerosis. | | Uses | Darapladib (SB-480848) is a reversible lipoprotein-associated phospholipase A2 (Lp-PLA2) inhibitor. | | 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. | | in vitro | darapladib potently inhibited lp-pla2 with an ic50 of 270 pm. a lack of selectivity against other secretory pla2s postulated to play a role in atherogenesis had been demonstrated. the percentage inhibition achieved when 1 μm darapladib was evaluated against human secretory pla2s iia, v and x, was 0, 0 and 8.7%, respectively [1]. | | in vivo | inhibition of lp-pla2 by darapladib led to attenuation of inflammation in vivo and decreased plaque formation in apoe-deficient mice, suggesting an anti-atherogenic role during the progression of atherosclerosis [2]. | | target | Lp-PLA2 | | storage | Store at -20°C | | references | [1] bui qt, wilensky rl. darapladib. expert opin investig drugs. 2010;19(1):161-8.
