DARAPLADIB Chemical Properties,Usage,Production

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].

storage

Store at -20°C
