Biological Activity
SB-201076 (20 min) potently and equally inhibits purified rat liver ATP citrate-lyase and recombinant human ATP citrate-lyase with a Ki of 1 µM[1].
SB-201076 (1 mM; 2.5 h) does not inhibit cholesterol or fatty acid synthesis in Hep G2 cells at concentrations up to 1 mM[1].
SB-201076 potently inhibits recombinant rat and human ATP citrate lyase with a Ki of 1 μM, acting competitively against citrate and noncompetitively against CoA[2].

SB-201076 (150 µmol/kg; i.v.; two doses administered 245 and 65 minutes prior to 3H2O injection) is delivered via intravenous administration of SB-204990 to rat liver, inhibiting hepatic cholesterol synthesis by 76% and hepatic fatty acid synthesis by 39%[1].
SB-201076 (10-25 mg/kg per day; p.o.; daily; 22 days) is delivered via chronic oral administration of SB-204990 to beagle dogs, resulting in sustained decreases in plasma cholesterol (up to 23%), plasma triglycerides (up to 38%), LDL cholesterol (40%), and HDL cholesterol (22%) over 22 days[1].
SB-201076 (p.o.) dose-dependently reduces plasma cholesterol by up to 46% and plasma triglycerides by up to 80% in rats[2].
SB-201076 (p.o.) dose-dependently reduces plasma cholesterol by up to 23% and plasma triglycerides by up to 38% in dogs[2].

Animal Model:Sprague-Dawley (male, 200-250 g body weight, maintained on reverse light cycle for 2 weeks prior to study)[1]
-
Dosage:150 µmol/kg (delivered as SB-204990)
-
Administration:p.o.; single dose
-
Result:Reached maximal plasma concentration of 41 nmol/mL at 4 hours after dosing.
Reached maximal hepatic concentration of 87 nmol/g at 4 hours after dosing, a level sufficient to inhibit ATP citrate-lyase relative to its Kᵢ of 1 μM.
