An inhibitor of glucose transport; partially inhibits glucose uptake in U937 and DU145 cells at 15-80 μM; sensitizes PPC-1 prostate cancer and U937 leukemia cells to FAS-induced cell death; also increases the expression of AspSyn and PCK2 at 50 μM; halts the cell cycle at the G0/G1 phase in U937 cells at 40 μM
