产品描述 | Tubastatin A (Tubastatin A BASE) is an effective and specific HDAC6 inhibitor (IC50: 15 nM, in a cell-free assay). Its selectivity is 1000-fold against all the other isozymes except HDAC8. |
靶点活性 | HDAC6:15 nM |
体外活性 | 与对照组相比,Tubastatin A 可使PCNA阳性细胞的量显著降低(34% vs 65%).在同基因大鼠原位胆管癌模型中,Tubastatin A(10 mg/kg)降低瘤重与肝重和体重(分别为5和5.6倍)的比值.在给弗氏完全佐剂诱导的动物炎症模型中,Tubastat A(30 mg/kg,i.p.)对鼠爪体积有显著抑制作用.Tubastat A(30 mg/kg,i.p.)处理胶原诱导型关节炎DBA1小鼠的爪子组织,使临床评分(70%)和IL-6表达显著降低. |
体内活性 | Tubastatin A(5 μM)剂量依赖性地使神经元细胞免于同型半胱氨酸诱导的死亡,10 μM时可完全避免。 Tubastatin A(10 μM)对组蛋白乙酰化有轻微诱导作用。作用于胆管癌细胞系时,Tubastatin A(10 μM)促使乙酰化α-tubulin水平增加和初级纤毛表达的恢复,初级纤毛表达的恢复与Hedgehog、MAPK信号通路下调、细胞增殖率(平均50%)和浸润(40%)减少相关。作用于脂多糖刺激的人类 THP-1巨噬细胞时,Tubastatin A明显抑制TNF-α和IL-6(IC50:272/712 nM)。作用于小鼠Raw 264.7巨噬细胞时,Tubastatin A剂量依赖性抑制一氧化氮分泌(IC50:4.2 μM)。 |
激酶实验 | HDAC enzymatic assays: Tubastatin A is dissolved and diluted in assay buffer (50 mM HEPES, pH 7.4, 100 mM KCl, 0.001% Tween-20, 0.05% BSA, and 20 μM tris(2-carboxyethyl)phosphine) to 6-fold of the final concentration. HDAC enzymes are diluted to 1.5-fold of the final concentration in assay buffer and pre-incubated with Tubastatin A for 10 minutes before the addition of the substrate. The amount of FTS (HDAC1, HDAC2, HDAC3, and HDAC6) or MAZ-1675 (HDAC4, HDAC5, HDAC7, HDAC8, and HDAC9) used for each enzyme is equal to the Michaelis constant (Km), as determined by a titration curve. FTS or MAZ-1675 is diluted in assay buffer to 6-fold the final concentration with 0.3 μM sequencing grade trypsin. The substrate/trypsin mix is added to the enzyme/compound mix and the plate is shaken for 60 seconds and then placed into a SpectraMax M5 microtiter plate reader. The enzymatic reaction is monitored for release of 7-amino-4-methoxy-coumarin over 30 minutes, after deacetylation of the lysine side chain in the peptide substrate, and the linear rate of the reaction is calculated. |
细胞实验 | Anchorage-independent growth is assessed by growing cells in soft agar. About 25,000 cells suspended in 0.4% agar in culture media are layered over a 1% agar layer in a 6-well plate. Media are added twice a week and pictures are taken after 21 days of incubation. The number and size of colonies are analyzed using the Gel-Pro software.(Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
