生物活性:
IHMT-MST1-58 is a potent, selective mammalian and orally active STE20-like protein 1 kinase (MST1) inhibitor with IC50 value of 23 nM. IHMT-MST1-58 can be used for the research of Type 1/2 diabetes.

体内研究:
IHMT-MST1-58 (compound 19) (p.o, 50 mg/kg/day, QD) combination with metformin led to the decline of fasting blood glucose, show protective effect of β cells and decrease the hemoglobin A1c level in the STZ-induced T1D/T2D mouse models.Pharmacokinetic Parameters of IHMT-MST1-58 in different species (i.v. or p.o; 1 mg/kg, 5 mg/kg and 10 mg/kg). miceratsbeagle dogs

体外研究:
IHMT-MST1-58 (compound 19) shows good activity against MST1 with an IC50 value of 23 nM.IHMT-MST1-58 (1 μM) displays strong inhibitory activity against MST1 (IC50 = 23 nM), weak activity against MST2 (IC50 = 652 nM), but no activity against NEK3 even at 10 μM (IC50 > 10 μM) .IHMT-MST1-58 (1 μM) shows strong binding affinity to MST1 and weak binding affinity to MST2 with Kd values of 240 nM and 2.7 μM.IHMT-MST1-58 (0.1-10 μM; 1-2 h) inhibits the phosphorylation of MST1 in vitro.IHMT-MST1-58 (0.03, 0.1 and 0.3 μM; 48 h) exhibits a significant protective effect of β cells from the damage caused by inflammatory cytokines.
