Cell experiment: | Human non-small cell lung cancer (NSCLC) cell lines H1299 and A549, human breast ductal carcinoma MCF7, as well as human nontumorigenic NL20 lung and MCF12A breast cells are maintained in cell culture media. Cells are treated with WZB117 for 24 or 48 hours. WZB117 (10 μM) is used in the experiments unless otherwise noted. Mock-treated and glucose deprivation samples served as negative and positive controls, respectively. In glucose deprivation, Dulbecco's Modified Eagle's Media (DMEM) with reduced glucose concentration (2 mM or 8% of glucose concentration in the regular cell culture medium) is prepared by mixing glucose-free DMEM with regular DMEM[1]. |
Animal experiment: | Mice[1]Male NU/J nude mice of 6 to 8 weeks of age are used. To determine the in vivo anticancer efficacy of WZB117 on human tumor xenograft growth, NSCLC A549 cells in exponential growth phase are harvested, washed, precipitated, and resuspended in PBS. Each mouse is injected subcutaneously with 5×106 cancer cells in the flank. Compound treatment started 3 days after the cancer cells injection and when all tumors become palpable. Tumor cell–injected mice are randomly divided into 2 groups: control group (n=10) treated with PBS/DMSO (1:1, v/v) and WZB117 treatment group (n=10) treated with WZB117 (10 mg/kg body weight) dissolved in PBS/DMSO solution (1:1, v/v). Mice are given intraperitoneal injection with either PBS/DMSO vehicle or WZB117 (10 mg/kg) daily for 10 weeks. Tumor sizes are measured every 7 days with calipers, and tumor volume is calculated[1]. |

IC50: ~0.6 μM for blocking glucose transport in diverse cancer cells
WZB117 is a glucose transporter 1 (Glut1) inhibitor.
Glucose transporter 1 (GLUT1), a uniporter protein that in humans is encoded by the SLC2A1 gene, facilitates the transport of glucose across the plasma membranes of mammalian cells. GLUT1 is responsible for the low level of basal glucose uptake to maintain respiration. Expression levels of GLUT1 in cell membranes are increased by reduced glucose levels and decreased by increased glucose.
In vitro: Previous study found that WZB117 could inhibit glucose transport in human red blood cells expressing Glut1 as their sole glucose transporter. Moreover, cancer cell treatment with WZB117 resulted in decreased levels of Glut1 protein, intracellular ATP, as well as glycolytic enzymes. All these changes were followed by increase in ATP-sensing enzyme AMP-activated protein kinase and declined in cyclin E2 as well as phosphorylated retinoblastoma, leading to cell-cycle arrest, senescence, and necrosis [1].
In vivo: Animal study showed that the daily ip injection of WZB117 at 10 mg/kg led to a more than 70% reduction in the size of human lung cancer of A549 cell origin [1].
Clinical trial: So far, no clinical study has been conducted.
