体内活性 | 方法:为检测体内抗肿瘤活性,将 (+)-JQ-1 (50 mg/kg,5% DMSO in 5% dextrose) 腹腔注射给携带 NMC 异种移植瘤的 NCr nude 小鼠,每天一次,持续十八天。 结果:(+)-JQ-1 治疗后,观察到明显的肿瘤消退和总生存率的提高。[1] 方法:为检测体内抗肿瘤活性,将 (+)-JQ-1 (50 mg/kg) 腹腔注射给携带人胃癌肿瘤 HGC27 的 nude 小鼠,每天一次,持续两周。 结果:(+)-JQ-1 阻止胃癌肿瘤生长并抑制肿瘤转移。[3] |
细胞实验 | Cells were plated at 5,000 cells per well of 96-well plates containing titrations of the compounds as indicated. After incubation, the cells were washed once with PBS and resuspended in 175 μL of ice-cold 70% ethanol and fixed for a minimum of 16 h at 4 °C. The cells were pelleted and washed 1× with PBS and stained for 30 min at room temperature (RT) with 120 μL of staining solution [propidium iodide (20 μg/mL), RNase A (25 μg/mL), 0.1% Triton X-100 in PBS]. Cell number and cell cycle data were obtained by using a flow cytometer using the Express Pro module. DNA content histograms were analyzed by using ModFit LT 3.2 Software. To calculate the number of viable cells in each well, the concentration of events measured using the Guava was multiplied by the volume of cells in the well, then by the fraction of cells in G1+S+G2/M. GI50 values for each cell line were calculated as the concentration of compound giving a 50% reduction in cell number relative to the DMSO control [4]. |
动物实验 | (Harlan) inoculated s.c. with 3 × 10^6 cells per mouse resuspended in 10% Matrigel. Two weeks later (average tumor volume 150 mm3), mice were assigned into two groups: 15 mice were treated with vehicle control (5:95 DMSO:10% 2-Hydroxypropyl-β-cyclodextrin), and 15 mice were treated with 30 mg/kg (+)-JQ1 by i.p. injection twice a day for 28 d. Body weight and tumor volume were measured daily. Tumor volume was calculated from caliper measurements by using the following formula: W × H × L × 0.52. Mice were killed when tumor volume reached 2,000 mm3, when body weight decreased >20% of initial weight, or when the mice were in poor health as established in the IACUC protocol. Survival was plotted and analyzed in GraphPad Prism software, and statistical significance was calculated by using log-rank (Mantel-Cox) and Gehan–Breslow–Wilcoxon tests. MV4-11 xenografts were established in nude mice injected with 10 × 10^6 cells per mouse. JQ1 was dosed i.p. and formulated as described above. Mice were divided into 4 groups of 10 animals: vehicle control once a day; 50 mg/kg (+)-JQ1 once a day; 30 mg/kg (+)-JQ1 twice a day; and cytarabine 100 mg/kg daily (5 d on, 2 d off). Treatment of mice with cytarabine at 100 mg/kg resulted in significant weight loss at day 8 and, therefore, the dose needed to be decreased to 75 mg/kg [4]. |
