Background:

LY2608204 is a activator of glucokinase (GK) with EC50 of 42 nM.IC 50 value: 42 nM (EC50)Target: glucokinasein vitro: LY2608204 activates glucokinase (GK) with EC50 of 42 nM at 10 mM glucose with a concentration dependent manner at lower glucose concentrations. LY2608204 also stimulates glucose metabolism in rat insulinoma INS1-E cells with EC50 of 579 nM.in vivo: LY2608204 decreases plasma glucose in a dose-dependent manner at both fasted and postprandial glucose levels. A maximal lowering of glucose AUC versus the untreated control group is observed with the high dose (30 mg/kg) and represents a 42% decrease. Interpolation of the data show that a 20% glucose AUC decrease occurs at an average LY2608204 concentration of 99 ng/mL (179 nM) in plasma, corresponding to a 6.9 mg/kg LY2608204 dose. The in vivo blood brain barrier permeability of LY2608204 results in a mean brain/plasma ratio of 0.17 five minutes post-dose with a mean total brain level of 0.539 nmol/g.Clinical trail:
