WZB117 (Synonyms: Glucose Transporter Inhibitor IV)

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].
