| In Vitro | Glucose uptake assays show that WZB117 inhibits glucose transport in cancer cells in a dose-dependent manner. The inhibition of glucose transport induced by WZB117 occurres within 1 minute after the assay started, suggesting that the inhibitory activity is likely to be via a direct and fast mechanism. Cell viability assay shows that WZB117 inhibits cancer cell proliferation with an IC50 of approximately 10 μM. The inhibitory activity of WZB117 on cancer cell growth is also confirmed with a clonogenic assay, which also indicates that the inhibition is irreversible in nature. WZB117 treatment results in significantly more cell growth inhibition in lung cancer A549 cells than in nontumorigenic lung NL20 cells. Similar results are also observed in breast cancer MCF7 cells and their nontumorigenic MCF12A cells. When WZB117 is added to cancer cells grown under hypoxic conditions, more cell growth inhibition is observed than under normoxic conditions[1]. |
| In Vivo | The animal study shows that after daily intraperitoneal injection of WZB117 at 10 mg/kg body weight, the sizes of the compound-treated tumors are on average more than 70% smaller than those of the mock (PBS/DMSO)-treated tumors. Notably, 2 of the 10 compound-treated tumors disappear during the treatment and never grow back even at the end of the study. Body weight measurement and analysis reveal that the mice treated with WZB117 lost about 1 to 2 grams of body weight compared with the mock-treated mice with most of the weight loss in the fat tissue. Blood counts and analysis of mice at the end of the study show that lymphocytes and platelets are changed in the compound-treated mice compared with the vehicle-treated mice, but the cell counts remained in the normal ranges. One of the concerns for using glucose transport inhibitors is that the inhibitor might produce hyperglycemia in the treated mice[1]. |
| Cell Assay | 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 Admin | 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]. |
