GNF4877 是一种有效的 DYRK1A 和 GSK3β 抑制剂（IC50：6纳米和 16纳米）。

GNF4877 is a potent DYRK1A and GSK3β inhibitor (IC50s: 6?nM and 16?nM). It?leads to blockade of nuclear factor of activated T-cells (NFATc) nuclear export and increased β-cell proliferation cells.

High glucose concentrations and glucokinase activators (GKAs) increase Ca2+ signalling in β-cells, and increase intracellular Ca2+ leads to activation of calcineurin and nuclear translocation of NFATc proteins. Indeed, concentrations of GNF4877 ((0.1?μM, 0.3?μM) well below the EC50 for β-cell proliferation are able to induce proliferation in the presence of high glucose or pharmacological activators of glucokinase. Finally, increasing intracellular Ca2+ with glibenclamide (a sulfonylurea receptor 1 inhibitor) or Bay K8644 (an L-type Ca2+ channel activator) show additive activity with GNF4877.

GNF4877 (50 mg/kg; oral gavage; twice a day; for 15 days; double transgenic RIP-DTA male mice) treatment induces β-cell proliferation, increases β-cell mass and insulin content, and improves glycaemic control. Animal Model:Double transgenic RIP-DTA male mice (Tg (Ins 2-rtTA) 2 Efr Tg (teto-DTA) 1 Gfi/J) with Doxycycline (28.8±2.4?g; 82±2 days) Dosage:50 mg/kg Administration:Oral gavage; twice a day; for 15 days Result:Induced β-cell proliferation, increased β-cell mass and insulin content, and improved glycaemic control.
