GNF2133 is a potent, selective and orally active DYRK1A inhibitor with IC50s of 0.0062, >50 µM for DYRK1A and GSK3β, respectively. GNF2133 shows good proliferation potency and efficacy on rat and human primary β-cell. GNF2133 significantly improves glucose disposal capacity and increases insulin secretion. GNF2133 has the potential for the research of type 1 diabetes[1].

GNF2133 (30 mg/kg; p.o.) shows good oral absorption with oral bioavailability of 22.3%[1].GNF2133 (30 mg/kg; p.o.; once a day for 5 days) shows the ability to proliferate β-cells in vivo[1].GNF2133 (3, 10, 30 mg/kg) significantly improves glucose disposal capacity and increased insulin secretion in RIP-DTA mice[1].Pharmacokinetic Parameters of GNF2133 in CD-1 mice[1]. plasma (iv) plasma (po) pancreas (po) CL (mL/min/kg)23.5Vss (L/kg)11AUC (h.nM)326810974144420 Cmax(nM)1977167513319tmax<(h)0.033.03.0Clast(nM)36.6191324t1/2<(h)6.63.46.6F (%)22.3CD-1 mice; 30 mg/kg; p.o.sup>[1].
