GKA50 quarterhydrate
GKA50 quarterhydrate is a potent glucokinase activator (EC50=33 nM at 5 mM glucose) and stimulates insulin release from mouse islets of Langerhans. GKA50 quarterhydrate is a glucose-like activator of beta-cell metabolism in rodent and human islets and a Ca2+-dependent modulator of insulin secretion. GKA50 quarterhydrate shows significant glucose lowering in high fat fed female rats.

Biologische Aktivität
Beschreibung
In Vitro
GKA50 (0.01-100 μM; 24 hours) enhances INS-1 cell proliferation with EC50 values ranging from 1 to 2 μM[2].
GKA50 (1.2 μM+40 μM glucose; 2-4 days) treatment reduces apoptosis induced by chronic high glucose in INS-1 cells[2].
GKA50 activates human glucokinase enzymatic activity with an EC50 of 0.022 μM. GKA50 stimulates insulin secretion in the pancreatic insulinoma cell line, INS-1, with an EC50 of 0.065 μM. GKA50 reduces chronic-high-glucose-induced apoptosis via modulation of glucokinase and apoptotic protein BAD[2].

Research Protocol for Endocrine Diseases
Endocrine diseases often arise from disrupted hormone production, hormone signaling, or target-tissue responsiveness; for diabetes-focused endocrine disease models, insulin signaling regulates glucose uptake, hepatic glucose output, lipid metabolism, and β-cell compensation. Type 2 diabetes develops through interacting defects in insulin resistance, β-cell dysfunction, adipose inflammation, hepatic glucose overproduction, altered incretin signaling, and ectopic lipid metabolism. A major unresolved question is whether endocrine dysfunction is driven primarily by target-tissue insulin resistance, intrinsic β-cell failure, immune/inflammatory stress, or combined multi-organ failure that differs by disease stage.

Human Islet Cell Culture
The method of preserving islets in vitro, with purified reduced immunogenicity. The steps are islet isolation, islet cell purification, in vitro determination of islet function and islet cell culture.

Ca2+ Staining Technique
Ca2+ staining is an experimental technique that utilizes specific fluorescent probes (such as Fluo-4 AM, Fura-2, etc.) to qualitatively or quantitatively detect dynamic changes in intracellular Ca2+ concentrations; this is achieved by monitoring the changes in fluorescent signals generated when these probes bind to free intracellular calcium ions. The underlying principle relies primarily on the presence of chelating groups within the probe's molecular structure that possess high affinity for calcium ions.
