Curcumin 是一种天然酚类,是乙酰转移酶p300/CREB 结合蛋白特异性抑制剂,抑制组蛋白/非组蛋白的乙酰化和组蛋白乙酰转移酶依赖的染色质转录。它对NF-κb 和MAPKs 有抑制作用,具有抗炎、抗氧化、抗增殖和抗血管生成等多种药理作用。
产品描述 | Curcumin is a phytopolylphenol pigment isolated from the plant Curcuma longa, commonly known as turmeric, with a variety of pharmacologic properties. Curcumin blocks the formation of reactive oxygen species, possesses anti-inflammatory properties as a result of inhibition of cyclooxygenases (COX) and other enzymes involved in inflammation; and disrupts cell signal transduction by various mechanisms including inhibition of protein kinase C. These effects may play a role in the agent's observed antineoplastic properties, which include inhibition of tumor cell proliferation and suppression of chemically induced carcinogenesis and tumor growth in animal models of cancer. |
靶点活性 | p300 histone acetylatransferase:25 μM |
体外活性 | Curcumin induces the expression of forkhead box protein O1 (FOXO1) through activation of extracellular signal-regulated kinase 1/2 signaling. Curcumin inhibits cell proliferation, which was associated with upregulation of the cyclin-dependent kinase inhibitors, p27 and p21, and downregulation of cyclin D1[2]. Curcumin induces endoplasmic reticulum (ER) stress and mitochondrial dysfunction as evidenced by up-regulation of CCAAT/enhancer binding protein homologous protein (CHOP), phosphorylation of JNK and down-regulation of SERCA2ATPase, release of cytochrome c, decrease of Bcl-2 and reduction of mitochondrial membrane potential in both AGS and HT-29 cells[3]. |
体内活性 | Chronic treatment with curcumin significantly reverses the CMS-induced behavioral abnormalities in stressed rats. Additionally, curcumin effectively inhibits cytokine gene expression at both the mRNA and the protein level and reduces the activation of NF-κB[4]. |
细胞实验 | 1×104 B16-R cells are cultivated as monolayer culture for 12 hr. They were then incubated in 200 μL of RPMI, 10% FBS containing curcumin at final concentrations from 1–100 μM in 96-multiwell plates for 24-48 hr. After these incubations, cells are washed twice in PBS and 500 μl of fresh culture medium containing MTT (0.3 mg/mL) are added for colorimetric assay. (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。
