Biological Activity

In vitro: PF-05175157 is not metabolized in rat, dog, or human microsomes. PF-05175157 is also stable in human hepatocyte incubations, but is minimally metabolized by recombinant human CYP3A4 and CYP3A5. PF-05175157 inhibits formation of malonyl-CoA in a concentration-dependent manner with a potency (EC50=30 nM) in rat hepatocytes consistent with its potency against rat ACC1 (24 nM).

In vivo: Oral administration (3 mg/kg) to rats and dogs show bioavailability of 40% and 54%, respectively, consistent with the low microsomal clearance and good solubility at low pH. Formation of the direct product of ACC, malonyl-CoA, in the skeletal muscle and liver of lean rats is assessed 1 h following an acute oral dose of PF-05175157, showing concentration-dependent reductions in both skeletal muscle and liver malonyl-CoA. At the nadir, quadriceps and liver malonyl-CoA levels are reduced by 76% and 89%, respectively. The EC50s for inhibition of quadriceps and liver malonyl-CoA are 870 and 540 nM, respectively, determined from unbind plasma concentrations of PF-05175157. Acute oral administration of PF-05175157 inhibits hepatic DNL in rats in an unbind plasma drug concentration-dependent manner. PF-05175157 inhibits up to 82% of the incorporation of [14C]acetate into [14C]lipids with an EC50 of 326 nM.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
