| 背景说明 | BI 2536是 PLK1 和 BRD4 的双抑制剂。 |
| 生物活性 | BI 2536 is a dual PLK1 and BRD4 inhibitor with IC50s of 0.83 and 25 nM, respectively. BI-2536 suppresses IFNB (encoding IFN-β) gene transcription.[1-4] |
| In Vitro | 超过从 10 nM 开始的 100 倍浓度范围,BI 2536 导致 HeLa 细胞以 4N DNA 含量积累,表明 G2 期或有丝分裂中的细胞周期阻滞。除了 HeLa 细胞外,BI 2536 还能有效抑制一组 32 种人类癌细胞系的增殖,这些细胞系代表不同的器官衍生 (包括乳腺癌、结肠癌、肺癌、胰腺癌和前列腺癌、黑色素瘤和造血系统癌) 和多种多样的肿瘤抑制基因或癌基因突变的模式 (包括 RB1、TP53、PTEN 和KRAS 状态)。该细胞组的半数最大有效浓度 (EC50) 值范围为 2-25 nM,而浓度为 100 nM 的 BI 2536 通常足以诱导完全的有丝分裂停滞。指数生长的 hTERT-RPE1、人脐静脉内皮细胞 (HUVEC) 和正常大鼠肾 (NRK) 细胞的增殖在 12-31 nM 的 EC50 值范围内被阻断,表明与将未转化的细胞循环至 BI 2536[3]。 |
| In Vivo | BI 2536 (40-50 mg/kg,iv) 在免疫缺陷的 nu/nu 小鼠中阻止人类癌症异种移植物的生长。每周一次或两次静脉注射 40-50 mg/kg BI 2536 的连续周期被发现在不同的异种移植模型中非常有效,例如 HCT 116 结肠癌完全抑制肿瘤,每周两次时间表 (处理与每周一次处理的对照 (T/C) 值为 0.3%,T/C 值为 16%;根据临床体征和没有重大体重变化来判断,这两种方案都具有良好的耐受性[3]。 |
| 细胞实验 | Cell proliferation assays are performed by incubation in the presence of various concentrations of BI 2536 (10 nM-1 μM) for 72 hr, and cell growth is assessed by the measurement of Alamar Blue dye conversion in a fluorescence spectrophotometer. Effective concentrations at which cellular growth is inhibited by 50% (EC50) are extrapolated from the dose-response curve fit[3]. |
| 动物实验 | Mice[3]Female BomTac:NMRI-Foxn1nu mice are grafted subcutaneously with HCT 116 colon-carcinoma, NCI-H460, or A549 lung-carcinoma cells by subcutaneous injection, respectively, of 2×106, 1×106, and 1×107 cells into the flank of each mouse. When tumors reached a volume of approximately 50 mm3, animals are pair-matched into treatment and control groups of ten mice each. In regression experiments, treatment is not initiated until the mean tumor volume reached 500 mm3. BI 2536 is injected intravenously into the tail vein at the indicated dose and schedule. The administration volume is 10 mL per kg body weight. Tumor volumes are determined three times a week with a caliper. The results are converted to tumor volume (mm3) by the following formula: length×width2×π/6. The weight of the mice is determined as an indicator of tolerability on the same days. For statistical analysis, the treatment group is compared with the vehicle control group in a one-sided (decreasing) exact Wilcoxon test. |
