General description
A cell-permeable thiazolylamide glucokinase (GK; Hexokinase IV/D) activator that reversibly targets a allosteric site that is only exposed for binding in the glucose-bound GK conformation, but not in the unbound "super-open" GK conformation or the GKRP- (GK Regulatory Protein) bound GK, and effectively stabilizes GK in an active conformation as well as prevents its interaction with and nuclear sequestration by GKRP, while exhibiting little effect against Hexokinase I/II/III. Compound A is shown to activate GK activity in cell-free assays (EC50 = 0.42 and 0.14 µM in the presence of 2.5 mM and 10 mM of glucose, respectively) and effectively induce cellular GK activation and increase glucose metabolism both in in rats (10 to 30 mg/kg, p.o.) in vivo and in rat islets and hepatocytes cultures (10 to 30 µM) in vitro.
