生物活性:
GLS1 Inhibitor-4 (compound 41e) is a potent GLS1 inhibitor with an IC50 of 11.86 nM. GLS1 Inhibitor-4 shows antiproliferative activity, good metabolic stability, robust GLS1 binding affinity. GLS1 Inhibitor-4 blocks the glutamine metabolism and induce the production of ROS. GLS1 Inhibitor-4 induces apoptosis and shows antitumor activity.

体内研究:
GLS1 Inhibitor-4 (50, 100 mg/kg; i.p.; twice a day for 21 consecutive days) shows antitumor activity in a dose-dependent manne.Animal Model:Six-week-old BALB/c SPF nude mice (HCT116 tumor nude mouse xenograft model)
Dosage:50, 100 mg/kg
Administration:I.p.; twice a day for 21 consecutive days
Result:Inhibited the tumor growth at a dose-dependent manne with the tumor growth inhibition (TGI) values of 35.5% at 50 mg/kg and 47.5% at 100 mg/kg, respectively.

体外研究:
GLS1 Inhibitor-4 (compound 41e) shows antiproliferative activity with IC50s of 0.051, 0.37, 0.32, 1.34 μM for HCT116 and MDA-MB-436, CT26, H22 cells, respectively.GLS1 Inhibitor-4 shows good plasma and liver microsomal stability with 96% stability in Human plasma.GLS1 Inhibitor-4 shows robust binding affinity with GLS1 protein, the dissociation constants (Kd) of 52 nM.GLS1 Inhibitor-4 (0.1, 0.5, 1 μM) inhibits the colony formation of HCT116 cells in a dose-dependent manner.GLS1 Inhibitor-4 (100, 300 nM, 12 h) reduces the concentration of a number of key metabolites downstream of glutamate within 12 h.GLS1 Inhibitor-4 (30, 50, 200 nM; 6 h) increases the ROS levels in a dose-dependent manner in HCT116 cells.GLS1 Inhibitor-4 (1 mmol/L; 12 h) significantly decreases the ATP production basal and maximal OCRs (oxygen consumption rates) after 12 h, suppresses the aerobic glycolysis in HCT116 cancer cells.GLS1 Inhibitor-4 (30, 50, 200 nM; 24 h) induces apoptosis in a dose-dependent manner.
