AM-2394 is a potent and selective Glucokinase agonist (GKA), which catalyzes the phosphorylation of glucose to glucose-6-phosphate. AM-2394 activates GK with an EC50 of 60 nM, increases the affinity of GK for glucose by approximately 10-fold, exhibits moderate clearance and good oral bioavailability in multiple animal models, and lowers glucose excursion following an oral glucose tolerance test in an ob/ob mouse model of diabetes

Type 2 diabetes mellitus (T2DM) is a disease characterized by elevated plasma glucose in the presence of insulin resistance and inadequate insulin secretion. Glucokinase (GK), a member of the hexokinase enzyme family, catalyzes the phosphorylation of glucose to glucose-6-phosphate in the presence of ATP.

Glucokioase i exok ase IV or D> is a glycolytic enssyiris that plays, an importaat. role irt blood sugar regulation .related to glucose utifeattoti a»d metabolism in the liver and pancreatic beta ^•cells. Serving as a glucose sessor, gtoeokiuase controls lasma glucose, levels. Glucokinaae plays a doal rob in .reducing plasma glucose levels; glucose-mediated activation of the en¾ymc in hepatocytes facilitates hepatic giocose npiafcc aad glycogen synthesis, while that la pancreatic beta ceils ultimately induces ins lin seeretio«. Both of these effects in turn reduce plasma glucose levels.

Clinical evidence has shown that, glueokitiase variants with, decreased, and increased activities are associated with mature easel, diabetes of the y ung { O0Y2) and persistent: hyperinsul nemic hypoglycemia &( infancy (PHHI), respectively. lso, aoo n.sulin dependent diabetes rneilitos (NIDDM) patients have been reported to have inappropriately lo giueokaiase activity; Ftirtherrnare. overexpressioa of glucokiuase it* dietary or gesetie animal models of diabetes either prevents, aoKiiorafes, or reverses the progress of pathological. symptoms in the disease. For these reasons, compounds that activate gfecokiaase have been sought by the pitasaaceatjeai liidustry.

International patent application, Publication No. WO 2 7/OS3345, which was published on May 10, 200?, discloses as giocokinase act ators certain 2-an«.aopyridiiie derivatives bearing at the 3 -position a meihyieneoxy-dkrked aromatic group a d on. the ammo group a heteroaryl ring, such as dna/oly! or i A4-lmadiazoiyl

it has .now been found that pyridyl ureas are useful as glneokirtase activators. Cettain of these •compounds have been, found to have an outstanding combination of properties that especially adapts them, for oral use to control plasma glucose levels.

Novel Series of Potent Glucokinase Activators Leading to the Discovery of AM-2394

Glucokinase (GK) catalyzes the phosphorylation of glucose to glucose-6-phosphate. We present the structure–activity relationships leading to the discovery of AM-2394, a structurally distinct GKA. AM-2394 activates GK with an EC₅₀ of 60 nM, increases the affinity of GK for glucose by approximately 10-fold, exhibits moderate clearance and good oral bioavailability in multiple animal models, and lowers glucose excursion following an oral glucose tolerance test in an ob/ob mouse model of diabetes.
