Aspulvinone O
Based on 1 Customer Validation
Aspulvinone O is a selective inhibitor of glutamate oxaloacetate aminotransferase GOT1. Aspulvinone O inhibits glutamine metabolism and reduces NADPH production, thereby inducing oxidative stress and apoptosis in pancreatic ductal adenocarcinoma (PDAC) cells. Aspulvinone O inhibits PDAC cell proliferation in vitro and tumor growth in xenograft models.

Aspulvinone O (0.1-100 μM; 48 h) inhibits the proliferation of pancreatic ductal adenocarcinoma cell lines (SW1990, PANC-1, AsPC-1) with IC50 of 20.54-26.80 μM, showing selectivity for cancer cells over normal cells[1].
Aspulvinone O (10-40 μM; 48 h) arrests the cell cycle of SW1990 cells at the S phase and induces apoptosis[1].
Aspulvinone O (10-40 μM; 24 h) reduces the levels of glutamine metabolic intermediates (OAA, malate) and the NADPH/NADP+ ratio[1] in SW1990 cells[1].

Cell Line:SW1990, PANC-1, AsPC-1 (human PDAC cells)
-
Concentration:0.1-100 μM
-
Incubation Time:48 h
-
Result:Dose-dependent growth inhibition with IC50 of 20.54 μM (SW1990), 26.80 μM (PANC-1), and 23.12 μM (AsPC-1), respectively, while showed no significant cytotoxicity (IC50 >100 μM) against normal HPDE6C7 cells.

Animal Model:CB17/scid male mice (8 weeks old, ~20 g), SW1990 cell-derived xenograft model[1]
-
Dosage:2.5 mg/kg, 5 mg/kg
-
Administration:Intraperitoneal injection (i.p.), daily for 14 days, starting when tumors reached ~3 mm diameter
-
Result:Significantly reduced tumor volume and weight compared to control. Showed a 60% reduction in tumor weight in the 5 mg/kg group, at day 14 and a 55% reduction in tumor volume.
Decreased levels of oxaloacetate (OAA) and malate (~50% reduction), increased aspartate (Asp) and glutamine (Gln) (~30% increase), and a 45% decrease in NADPH/NADP+ ratio compared to control.
No significant changes in body weight or histomorphology, indicating good tolerability.
