体外研究 (In Vitro) |
根据葡萄糖摄取测定,WZB117 以剂量依赖性方式减少癌细胞中的葡萄糖转运。该测定在不到一分钟内完成,表明 WZB117 诱导的葡萄糖转运减少可能是快速直接机制的结果。根据细胞活力实验,WZB117 减少癌细胞增殖,IC50 约为 10 μM。克隆实验验证了WZB117对癌细胞发育的抑制作用,并证明了这种抑制的不可逆性。 WZB117疗法对肺癌A549细胞的细胞生长抑制作用远大于对非致瘤性肺NL20细胞的细胞生长抑制作用。 MCF7 乳腺癌细胞和非致瘤性 MCF12A 细胞表现出类似的结果。据报道,与常氧环境相比,当将 WZB117 给予在缺氧环境下培养的癌细胞时,细胞发育受到更大的抑制 [1]。

体内研究 (In Vivo) |
根据动物研究,与模拟 (PBS/DMSO) 治疗的肿瘤相比,每日腹膜内注射 10 mg/kg 体重剂量的 WZB117 后,化合物治疗的肿瘤平均大小减少了近 70%。最令人惊讶的是,治疗后,用化合物治疗的 10 个肿瘤中有 2 个停止生长,甚至在试验期间消失。与模拟处理的小鼠相比,WZB117 处理的小鼠体重减轻了 1 至 2 克,其中脂肪组织占体重减轻的大部分。这些发现基于体重的测量和分析。该研究的结论显示,虽然细胞计数保持在正常范围内,但化合物治疗的小鼠的淋巴细胞和血小板计数与载体治疗的小鼠不同。使用葡萄糖转运抑制剂引起了某些担忧,因为接受治疗的小鼠可能会出现高血糖[1]。

蛋白质靶点研究I:红细胞膜囊泡制备和葡萄糖摄取测定[1]
红细胞和红细胞衍生的囊泡是使用已发表的方案进行微小修改制备的。使用密封囊泡的葡萄糖摄取测定与RBC中的类似,不同之处在于在每次洗涤步骤后以18000×g离心20分钟以沉淀囊泡。 蛋白质靶点研究II:对接研究[1] 使用Spartan 10构建WZB117的分子模型(Wavefunction股份有限公司;参考文献23)。在默克分子力场的分子力学能量最小化之后,将化合物结构导出到Macromodel,并对接到Glut1同源性建模的PDB结构1SUK蛋白质和网格制备使用默认方案的FirstDiscovery 2.7的Glide模块进行,并以传输通道的中间为中心,边界框包围整个通道。然后使用Glide对接WZB117,并根据Glide计算的Emodel值选择化合物的最佳对接结构。 蛋白质印迹分析、RNA分离和实时聚合酶链式反应[1] 使用标准方案进行蛋白质印迹分析。Glut1(H-43)、eIF2α和环磷酰胺-阿霉素-长春新碱-泼尼松(CHOP)的抗体来自Santa Cruz;PGAM1抗体来自Novus Biologicals。p-eIF2α抗体来自Invitrogen。 使用RNeasy总RNA提取试剂盒从处理的A549细胞中分离RNA,并使用Bio-Rad iScript Select cDNA合成试剂盒合成cDNA。使用Bio-Rad iCycler和Bio-Rad iQ SyBr Green Supermix试剂盒,使用所产生的cDNA来特异性地定量SLC2A1(Glut1)的转录物。人SLC2A1和β-肌动蛋白的RT2-PCR引物组来自SuperArray。为了量化转录水平,使用了δCt方法。β-肌动蛋白mRNA用作使Glut1 mRNA正常化的内部对照。 乳酸和ATP测量及ATP抢救研究[1] 使用乳酸测定试剂盒II测量细胞外乳酸浓度。 使用来自Perkin-Elmer的ATPlite发光ATP检测测定系统测量细胞内ATP浓度。简言之,将细胞以50000个细胞的密度接种在96孔板的每个孔中。在治疗6、12和24小时后测量ATP水平。测定每个孔中细胞的蛋白质浓度,用于信号归一化的乳酸和ATP测量。 在细胞拯救研究中,在含有或不含有30μmol/L WZB117的96细胞板的癌症细胞的细胞培养基中加入不同浓度的ATP。在处理后24小时通过MTT测定法测量细胞内ATP水平和细胞活力。 |

癌症细胞和人红细胞葡萄糖摄取测定[1]
如前所述,通过测量2-脱氧-d-[3H]葡萄糖的细胞摄取来分析化合物对葡萄糖转运的抑制活性。 类似的程序用于人红细胞(RBC)的葡萄糖摄取测定,不同之处在于通过以2000×g离心5分钟来洗涤和收集RBC,因为它们是悬浮细胞,并且在测量放射性之前,将处理过的RBC溶解在0.1%SDS中。 细胞增殖(MTT)和克隆形成测定[1] 使用MTT增殖测定试剂盒(Cayman)或克隆原测定法测量细胞增殖和存活率。 缺氧研究[1] 癌症细胞缺氧研究是使用Anaerobe气体生成袋系统和指示剂进行的。该袋形成无氧环境,在该无氧环境中将化合物处理的细胞孵育24小时。缺氧孵育后,通过MTT测定法测量处理的细胞的生存能力。 |
动物实验 |
Male NU/J nude mice of 6 to 8 weeks of age were purchased from The Jackson Laboratory and were fed with the Irradiated Teklad Global 19% protein rodent diet from Harlan Laboratories. To determine the in vivo anticancer efficacy of compound WZB117 on human tumor xenograft growth, NSCLC A549 cells in exponential growth phase were harvested, washed, precipitated, and resuspended in PBS. Each mouse was injected subcutaneously with 5 × 106 cancer cells in the flank. Compound treatment started 3 days after the cancer cells injection and when all tumors became palpable. Tumor cell–injected mice were 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 were given intraperitoneal injection with either PBS/DMSO vehicle or compound WZB117 (10 mg/kg) daily for 10 weeks. Tumor sizes were measured every 7 days with calipers, and tumor volume (L × W2/2) was calculated and presented as means ± SEM. All of the procedures involved in animal study were conducted in conformation with the guidelines of both Ohio University and NIH.[1]

其他信息 |
WZB-117 is a diester resulting from the formal condensation of the two hydroxy groups of 3-fluorocatechol with the carboxy groups of 3-hydroxybenzoic acid. It is an inhibitor of glucose transporter 1 (GLUT1) that suppresses tumour growth in mouse xenograft models. It has a role as an antineoplastic agent, a glucose transporter 1 inhibitor and a radiosensitizing agent. It is a diester, a member of phenols, a benzoate ester and a member of monofluorobenzenes. It is functionally related to a 3-hydroxybenzoic acid and a 3-fluorocatechol.

Small-molecule WZB117 and its inhibitory actions on glucose uptake and cancer cell growth. Glucose transport and cell proliferation of WZB117-treated cancer cells was measured by glucose uptake and MTT cell viability assays, respectively. A, structure of WZB117. WZB117 is a structural analogue of WZB115 (21) with a more potent anticancer activity and a molecular weight of 368.31 Da. B, WZB117 inhibits glucose transport in A549 cancer cells in a dose-dependent manner. C, WZB117 rapidly and completely inhibits glucose transport in cancer cells. WZB117 (30 μmol/L) was used to treat A549 cells. Glucose uptake in the treated cells was measured at 0, 1, 5, 30, 60, and 120 minutes after the addition of 2-deoxy-d-[3H] glucose. D, WZB117 treatment led to irreversible cell growth inhibition in 3 cancer cell lines as determined by clonogenic assays. E, WZB117 inhibits cell proliferation in the human lung cancer cell line A549 significantly more than it does in NL20 nontumorigenic lung cells 48 hours after treatment. ***, P ≤ 0.001. F, WZB117 treatment under hypoxic condition further reduced cancer cells' proliferation rate. A549 cells were treated with or without 10 μM WZB117 and were then immediately transferred and maintained in a hypoxic pouch. The viability of the treated cells was measured 24 hours after treatment. A549 cells in normal or low-glucose cell culture media treated under normoxia or hypoxia conditions served as controls. **, P ≤ 0.01. Mol Cancer Ther . 2012 Aug;11(8):1672-82. td> |
Small molecule WZB117 inhibits cancer growth in tumor-bearing nude mice. A, daily intraperitoneal injection of WZB117 at 10 mg/kg body weight for 10 weeks resulted in more than 70% reduction in tumor volume of human A549 lung cancer grafted on nude mice. PBS/DMSO (1:1, v/v) were injected in the mock-treated control mice. N = 10 for each treatment group. *, P < 0.05. B, photographs of untreated or WZB117-treated tumor-bearing nude mice with representative tumors. Photographs were taken 8 weeks after the compound treatment. The middle images represent tumors close to the average tumor sizes of the groups. The tumor on the mouse of the WZB117-treated group (bottom right) disappeared during the study.

Glycolysis studies: WZB117 treatment resulted in changes in levels of glycolytic proteins and metabolites and addition of ATP rescued WZB117-treated A549 cells. A549 cells were treated with WZB117 for various times and then mRNA, proteins, and metabolites of the cells were measured. Glucose deprivation samples served as controls. *, P ≤ 0.05; **, P ≤ 0.01; ***, P ≤ 0.001. Western blot analyses were conducted 3 times. Intensities of protein bands were first normalized with their respective β-actin controls and then further normalized by arbitrarily setting the relative intensity of the mock-treated sample of that time point as 1 in histograms. A, RT-PCR analysis of Glut1 mRNA level. B, Glut1 protein levels of WZB117-treated A549 cells analyzed by Western blotting. C, extracellular lactate levels secreted by A549 cells treated with or without WZB117. Lactate concentration of mock-treated samples was assigned as 100%. D, intracellular ATP levels of cancer cells treated with or without WZB117. Mock-treated and glucose deprivation samples served as negative and positive controls, respectively, and the ATP concentration of mock-treated samples was assigned as 100%. E, addition of extracellular ATP rescued WZB117-treated but not paclitaxel-treated A549 cells. Cells were treated with various concentrations of ATP in the presence of either 30 μmol/L WZB117 or 1 μmol/L paclitaxel for 24 hours, and the cell viability was measured. F, synergistic anticancer effect between WZB117 and a mitochondria inhibitor oligomycin. A549 cells were treated with 1 μmol/L WZB117 in the absence or presence of 50 nmol/L oligomycin. G, glycolytic enzyme changes over time in WZB117-treated A549 cells. This experiment was repeated 3 times. Mol Cancer Ther . 2012 Aug;11(8):1672-82. td> |
