产品描述 | CX-5461, a selective inhibitor of rRNA synthesis, suppresses Pol I-driven transcription of rRNA. |
靶点活性 | Pol I-driven transcription of rRNA:142 nM |
体外活性 | 在HCT-116(EC50=167 nM),A375(EC50=58 nM),和MIA PaCa-2(和EC50=74 nM)细胞系中,CX-5461能够抑制细胞增殖。在固体肿瘤细胞中,CX-5461诱导细胞自噬或衰老,但不诱导细胞凋亡,其中qi黑色素瘤 A375 (Pol I IC50 = 113 nM;Pol II IC50 > 25 μM)和胰腺癌MIA PaCa-2 (Pol I IC50=54 nM;Pol II IC50 ~25 mM)。在HCT-116细胞中,CX-5461选择性抑制rRNA合成,Pol I(IC50=142 nM),Pol II (IC50 > 25 μM)。 |
体内活性 | 在异种移植人固体肿瘤的小鼠模型中,通过口服CX-5461(50 mg/kg)表现出抗实体瘤活性. |
激酶实验 | Pol I and Pol II Transcription Assay: Two short-lived RNA transcripts (half-lives ~20-30 minutes), one produced by Pol I and another by Pol II, are quantitated by qRT-PCR as a measure of CX-5461-related effects on transcription. The 45S pre-rRNA served as the Pol I transcript and the mRNA for the protooncogene c-myc served as the comparator Pol II transcript. Both Pol I and Pol II transcription are known to be affected by general cellular stress. To minimize the potential effects of such stress, cells are exposed to test agents for only a short period of time (2 hours). This is sufficient time for these transcripts to be reduced by greater than 90% if CX-5461 affects their synthesis. |
细胞实验 | Cells are plated on 96-well plates and treated the next day with dose response of CX-5461 for 96 hours. Cell viability is determined using Alamar Blue and CyQUANT assays(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。
