The Glucokinase Activator, Cpd A, also referenced under CAS 603108-44-7, modulates Glucokinase. This small molecule/inhibitor is primarily used for Activators/Inducers applications.
Synonym(s):
Glucokinase Activator, Cpd A, Hexokinase D Activator, Hexokinase IV Activator, 2-Amino-5-(4-methyl-4H-(1,2,4)-triazole-3-yl-sulfanyl)-N-(4-methyl-thiazole-2-yl)benzamide, Compound A
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.

Uncoupling protein 2 (UCP2), a mitochondrial protein, is known to be upregulated in pancreatic islets of patients with type 2 diabetes (T2DM); however, the pathological significance of this increase in UCP2 expression is unclear. In this study, we highlight the
Pancreatic β cells couple nutrient metabolism with appropriate insulin secretion. Here, we show that pyruvate kinase (PK), which converts ADP and phosphoenolpyruvate (PEP) into ATP and pyruvate, underlies β cell sensing of both glycolytic and mitochondrial fuels. Plasma membrane-localized PK
