产品描述 | MC1568 is a specific HDAC inhibitor for maize HD1-A (IC50: 100 nM, in a cell-free assay). It is 34-fold more selective for HD1-A than HD1-B. |
靶点活性 | HD1-A (Maize):100 nM |
体外活性 | 在胰脏移植研究中,MC1568增强内分泌β和δ-cells细胞,并使Pax4的表达增强. 在鼠体内,MC1568(50 mg/kg)组织选择性地显著抑制HDAC. 在PPRE-Luc鼠体内,MC1568(50 mg/kg)主要损害心脏和脂肪组织部位PPARγ信号.作用于骨骼肌和心脏时,MC1568抑制HDAC4/5的活性,不影响HDAC3活性,故MEF2-HDAC复合体处于未激活状态. |
体内活性 | MC1568对HDAC II的选择性抑制效果(IC50:220 nM)是I型的176倍。作用于C2C12细胞时,MC1568(5 μM)通过降低肌细胞增强因子2D的表达,使HDAC4-HDAC3-MEF2D复合体稳定,并抑制分化诱导的MEF2D乙酰化,从而使肌细胞生成被阻断。MC1568(5或10 μM)可使RAR和PPARγ调节的分化诱导信号通路受干扰。 在MCF-7细胞中,MC1568(20 μM)使乙酰化H3和H4组蛋白的累积增强,并提高乙酰基微管蛋白的水平,表明MC1568可抑制HDAC6。作用于人类乳腺癌ZR-75.1细胞裂解物时,MC1568对HDAC1无抑制作用,但是可使HDAC4受抑制。作用于F9细胞时,MC1568选择性抑制内胚分化,对VA诱导的早幼粒NB4细胞成熟无影响。作用于3T3-L1细胞时,MC1568使PPARγ诱导的脂肪生成降低。 |
激酶实验 | Maize HD2, HD1-B, and HD1-A Enzyme Inhibition.: The enzyme liberats tritiated acetic acid from the substrate, which is quantified by scintillation counting. IC50 values are results of triple determinations. A 50 μL sample of maize enzyme (at 30 °C) is incubated (30 min) with 10 μL of total [3H]acetate-prelabeled chicken reticulocyte histones (2 mg/mL). Reaction is stopped by addition of 50 μL of 1 M HCl/0.4 M acetate and 800 μL of ethyl acetate. After centrifugation (1×104 g, 5 min), an aliquot of 600 μL of the upper phase is counted for radioactivity in 3 mL of liquid scintillation cocktail. MC1568 is tested at a starting concentration of 40 μM, and active substances are diluted further. NaB, VPA, TSA, SAHA, 85 TPX, HC-toxin, and tubacin are used as the reference compounds, and blank solvents are used as negative controls. |
细胞实验 | The 3T3-L1 cells are propagated and differentiated using a cocktail of isobutylmethylxanthine, dexamethasone, and insulin. From the second day post-confluence and throughout the differentiation period of 8 days, the 3T3-L1 cells are induced by: (1) no induction: at post-confluence and throughout the differentiation period of 8 days, the cells are incubated with DMSO or MC1568. (2) troglitazone: at post-confluence and throughout the differentiation period of 8 days, the cells are induced with 5 μM troglitazone, MC1568, or both. (3) rosiglitazone: at post-confluence and throughout the differentiation period of 8 days, the cells are incubated with 1?μM rosiglitazone and either DMSO or MC1568. (4) rosiglitazone and dexamethasone: at post-confluence, the cells received 1?μM of rosiglitazone and 390?ng/mL dexamethasone. Throughout the differentiation period of 8 days, the cells are induced with 1?μM of rosiglitazone and either DMSO or MC1568. All medium is renewed every second day.(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。
