Description

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[1].

IC50 & Target[1]

MST1

23 nM (IC50)

In Vitro

IHMT-MST1-58 (compound 19) shows good activity against MST1 with an IC50 value of 23 nM[1].
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) [1].
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[1].
IHMT-MST1-58 (0.1-10 μM; 1-2 h) inhibits the phosphorylation of MST1 in vitro[1].
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[1].

Western Blot Analysis[1]

Cell Line: HepG2 liver cells, RAW264.7, RPE1 and HL7702 cells; INS-1 and RIN-m5F cell lines
Concentration: 0-10 μM
Incubation Time: 2 h (HepG2 liver cells, RAW264.7, RPE1, and HL7702 cells)
Result: Inhibited the H2O2-stimulated MOB1 phosphorylation and MST1/2 autophosphorylation in a dose-dependent manner in all four cell lines.
Inhibited the phosphorylation of LATS1 (T1079) and YAP (S127) in HepG2 cells.
Showed strong inhibition of MST1 phosphorylation and its downstream MOB1 autophosphorylation in a dose-dependent manner in both cell lines.
In Vivo

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[1].
