产品描述 | Vorinostat (suberoylanilide hydroxamic acid) is a pan-inhibitor of Histone Deacetylase with antineoplastic activity (IC50: ~10 nM). |
靶点活性 | HDAC:~10 nM (cell free) |
体外活性 | Vorinostat (SAHA) efficiently suppressed MES-SA cell growth at a low dosage (3 μM) already after 24 hours treatment. Decrease of cell survival was even more pronounced after prolonged treatment and reached 9% and 2% after 48 and 72 hours of treatment, respectively. Colony forming capability of MES-SA cells treated with 3 μM vorinostat for 24 and 48 hours was significantly diminished and blocked after 72 hours [1]. SAHA inhibits HDAC1 and HDAC3 activity in vitro. Treatment of cells in culture with SAHA results in a marked hyperacetylation of histone H4 [2]. The concentrations of SAHA of ≥2.5 μM caused profound growth arrest. The IC50 of 0.75 μM was calculated as 50% reduction in cell number after 120 h of continuous exposure to SAHA. Cell cycle analysis evaluated after 48 h exposure to SAHA showed an accumulation of cells predominantly in G1 at low concentrations (1.25 and 2.5 μM) [3]. |
体内活性 | Nude mice injected with 5 x 10^6 MES-SA cells were treated for 21 days with vorinostat (50 mg/kg/day) and, in comparison to placebo group, a tumor growth reduction of more than 50% was observed [1]. For comparison, 100 mg/kg SAHA in either HOP-β-CD or DMSO was administered to WT and R6/2 by single i.p. injection. It had no difference in the degree of histone acetylation between untreated WT and R6/2 mice. Significant increases in histone acetylation could be detected only on s.c. administration of 200 mg/kg [4]. |
细胞实验 | Cells were plated onto 100-mm tissue culture plates at a density of 2 × 10^6 for 48 h and then treated with SAHA or equal concentrations of the vehicle. For longer drug exposure times, medium with drug or vehicle were exchanged every 48 h. For wash-out experiments, cells were treated with SAHA daily for 60–72 h (drug and medium were exchanged at 48 h), then SAHA was washed out and replaced with 10% FCS containing DMEM [3]. |
动物实验 | Athymic Nude-Foxn1nu/nu mice were used in the present study. They were housed at 22°C at a constant light-dark cycle (12-h light, 12-h dark) and had free access to water and rodent chow (4-5% fat, 21% protein). Twelve weeks old male mice (n = 14) were anesthetized with Isofluran and 5 × 10^6 MES-SA cells were injected subcutaneously into the right flank of the animal. Mice from a control group received placebo containing 300 μl of empty HOP-β-CD (2-hydroxypropyl-β-cyclodextrin) vesicles. Another group of mice received vorinostat dissolved in HOP-β-CD at a concentration of 50 mg/kg/day. Both, empty vesicles and vorinostat were administered intraperitoneally, starting on the day 4 after the injection of MES-SA tumor cells. Mice body weight and tumor size (w2 × l × 0.52; measured by caliper) were estimated twice a week. All mice were treated for 21 days and afterward sacrificed by cervical dislocation. Each tumor was isolated as a whole and different tumor parameters (weight, volume, size, and macroscopic appearance) were determined. Finally, tumor slices were cryopreserved and formalin fixed (4%) for further analyses [1]. |

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。
